Chapter 1:A New Journey

Author's Note

IMPORTANT: Before you read the story, read this:

This story is the sequel to my other story, Quest For the Cure.Originally, I was going to 'ponify' my original story but then I thought it will be much cooler if I just start from scratch and make a sequel.Note that if you haven't seen Quest For the Cure yet, you should go and read that because this is the sequel and does have a story behind Twilight and Frisk's friendship.Just click the link listed on the synopsis to read it.

Now, if you have seen my original story, then you may move on!Enjoy the sequel!:twilightsmile:

Chapter 1:A New Journey

'Hold on tight,' Twilight said to her friend, flying through the sky.

'I'm glad you finally decided to take me to your place, we have been friends for a long time,' said Frisk.

Frisk is now much older than how she used to be, but the 23-year-old still thrived throughout her life. She might have been older if it weren't for the age spell Twilight learned to perform. After her showdown with Gromiz, the evil former emperor of her country, life has been pretty well but became a bit predictable, thus began their next journey in Twilight's world: The land of Equestria.

As they flew closer to the brink of the atmosphere of Earth, Twilight did the spell she used to fly to Earth years ago. 'This may be a complicated spell...Hold still while I perform it,' she reminded Frisk.

Soon, a big bubble-like thing wrapped the two inside, allowing them to breathe normally even in outer space.

'Where did you find this spell?This is amazing!' Frisk exclaimed.

'I might have been teaching my friend Starlight about friendship, but she has a very good knowledge of magic.' Twilight replied.

Upon hearing her friend's name, Frisk was curious. 'Starlight?Who is she?'

'Oh, it's a long story.She is now a good friend of mine.We had differences in the past but I was able to befriend her.Well since it will take quite a while to get to the planet I might as well tell you the story.' she explained.

Spike had a grin on his face. 'It's actually quite dramatic.' He added.

A whole lot of story-telling about time traveling and all these alternate universe stuff (I suppose you guys know the story, also I broke the fourth wall lol), Frisk was really excited. 'Wow, I really want to know more about you and your friends, it would be so awesome!' As she was saying that, depths she accidentally fell off of Twilight.

She was expecting herself to plunge depths of space when...The bubble protected her.

'Oh!I forgot to mention, this bubble actually protects anything inside from the surroundings, and the direction of how it moves actually depends on where the controller, for example being me, flies toward to.' Twilight explained further.

'So I actually could've walked the whole time inside here, huh?' Frisk asked.

'Well...Technically yes, but I will have to keep flying. Don't worry, I did say I was a unicorn before but I got used to these wings.' She giggled.

After flying for a ridiculously large amount of time, Twilight told Frisk she finally got to the point where she can teleport near the planet.

'Phew!I guess that long amount of flying was worth it right Twilly?' Frisk laughed.

'Geez, you would NOT be saying that if YOU were the one flying,' Twilight yelled at her, panting like crazy. 'There's no way I could have lasted this long if I didn't have a spell that can temperately let me rest inside this bubble.'

'Alright let's not get into an argument here guys, let's just let Twilight teleport us to Equestria.' Spike interrupted them.

'Ah yes, sorry Spike, I'll do it now.' She turned to Frisk. 'Hold still,' she warned.

And in a flash of light, Twilight teleported the three, and as Frisk opened her eyes, a beautiful planet came in sight.

'So this is Equestria, the place you talked about?' Frisk turned to Twilight.

Twilight was pleased. 'It looks just as pretty as it looked before.This magical land...You will love it here,' She smiled.

Chapter 2:Reunion with shocking news

Something has gone wrong. We don't seem to have an archived copy of that chapter.

Chapter 3:The discussion

Frisk woke up during the middle of the night (Well, it's actually always night), and to see Twilight wasn't by her side.

'Where did she run off to?' She thought.She ran into the forest to see if she can find her.Later, she went back to the empty spot she landed at, and there's Twilight, sitting there alone in the night.

'Twilly?Are you okay?' She asked.

'Oh...It's nothing.I just...need some time alone, nothing special.' Twilight replied in a soft voice.

As she turned around to face Frisk, her face was actually covered in tears.

'Are you crying?What happened?' She sat down next to her friend.

'It was my fault...All of this right now...It's because of what I did...' Twilight was sobbing.

Frisk was curious why. 'How can you say it's your fault?You had to use the elements to come save Earth.It was the core thing that helped us save my country.'

'You don't get it,' Twilight cried. 'Equestria's most important defense is the elements, I altered the timeline to get the elements back when Nightmare moon was attacking the place since that time is possibly the only time I can steal the elements of harmony without anyone noticing.Since the elements aren't there anymore, she beat our former ruler...Princess Celestia,' She explained.

'But why didn't anything change really?You said when Starlight was traveling through time history was altered greatly!'

'That's because when she prevented the 'rainboom' from Rainbow Dash happening, it wasn't able to connect us together since we actually got our 'cutie marks' at the same time and we had a special connection.Without it, over won't be stopping multiple forces from attacking Equestria.'

Frisk let out a sigh.She put her around her to comfort her friend. 'Look, Twilight, sometimes these things happen.You can't be able to do something if you don't sacrifice something else.That's the same case with you now.Through my experiences, I think you can do it.We can defeat Nightmare Moon again and send her to where she belongs.Because as far as I know, friendship is a powerful thing.You taught me that the first day I met you.We brought the elements with us, we can defeat her pretty soon.' She calmly told her.

Frisk helped Twilight dry her tears and waited for her to calm down. 'Thank, Frisk, I am glad I met you that day.' She said, still sniffing from her tears.

'Let's actually get some rest and move on.' Frisk suggested.

The next day, still under the moonlight, the group was talking about their plan to defeat Nightmare Moon once and for all, until Twilight came in.

'Hey, girls...I have a confession to make.' She said anxiously.

'You can tell us if you want to, I don't mind,' Fluttershy replied.

She got her bag and reached for the elements.Everypony gasped in shock of her keeping them for so long.

'What!?You had them all along?' Rainbow exclaimed.

Twilight sighed.She knows this won't be good for her. 'Let me explain what happened...'

'So that time traveling spell you told me to do...It was for this?' Starlight asked her.

'I know girls, it was my fault I altered the timeline, I am so sorry...' Twilight was going to cry again.

Being the understanding pony she is, Applejack went over to her. 'Twilight, you sacrificed the one thing that we depended on to beat out other bad forces attacking.But trust me, it was for a good cause.'

Even the very unserious Pinkie Pie had her mane deflated. 'You saved Earth because of the elements of harmony!That makes up for it right?'

While Twilight was still feeling a bit guilty at first, seeing her friends being so nice to her, she finally puts that away as a thing in the past.All she needed to do was ask for their forgiveness.

'So...After al, I did, after everything, I altered to make Equestria such a miserable place...Can you all forgive me?' She said softly.

Everypony nodded and went over to comfort her, even Frisk did!

'You're never alone Twilight, we will always be with you.' Frisk smiled.

Twilight got herself free from her friends. 'Thanks, girls, it means a lot.' She said, relieved. 'So, what's the plan?'

Rainbow Dash immediately spoke up. 'Alright listen up everypony, our plan will go a little like this...'

The plan was surprisingly simple; Use the elements, storm the castle, defeat Nightmare Moon and send her to the moon, done.Call it a day and everypony's lives return to normal.

'I thought you ponies would have a pretty like complicated plan, I didn't expect to be so direct, though.' Spike said.

'Sometimes the best plans are the most direct ones,' Starlight punched him playfully. 'Now that we are all back together, we can use the elements that Twilight just so happened to bring with her to defeat Nightmare Moon!'

But, what they didn't expect, was what happened after Frisk used the elements for saving her country.

'Girls, I'm afraid this plan won't work...' Twilight said mid-way.

'What!?Why not?' Rainbow shouted.

'Calm down Dash, she must have a reason,' Rarity told her.

Frisk sighed. 'When I used to elements to be able to give myself the ability to save my country from that stupid emperor, Twilight told me the magic from them was nearly drained after that long fight.I suppose you guys would definitely not want to wait forever for them to charge to its maximum potential, but I don't know how else we would possibly be able to charge it up faster.'

And everypony instantly became hopeless on their plan.

'I thought it would be this easy,' Fluttershy said. 'But through our experiences, dealing with sins wasn't easy.'

But then, Starlight had an idea. 'Twilight, did you tell me before how the elements get the magic from?'

'It's obviously none other than friendship, of course.'

'Why don't we help the crystals regain their power through spreading friendship?It is very simple, considering you are the princess of friendship.' She suggested.

'But how in Equestria are we gonna do that?' Applejack asked. 'We aren't getting much friendship problems after Nightmare Moon took over this place!'

It took a bit of silent thinking for the plan to work out.At last, Frisk thought of something. 'Speaking of which, I haven't really got used to this world yet...Maybe I can possibly help you all, while trying to blend in at the same time.'

'It's worth a shot,' Starlight replied. 'Without friendship, I don't think we will be using them in the battle.'

'Great idea!While you recharge the power of the crystals, you can learn more about friendship as well!' Twilight said. 'Okay, new plan.Frisk and I will be going around spreading friendship and help recharge the elements.Starlight,you're coming with us too.' She suggested, winking at Starlight.

'I guess I can help a little,' She thought, feeling shy.

'While we're doing that, the rest of you can work on our battle plan.Applejack, Dash, you two go sneak on the guards so we can easily break through into the throne room.Pinkie Pie, go with them to try and distract the guards so they can carry out their part.And for Rarity and Fluttershy, you get to discuss what works after they come back.In the meantime, make sure everypony is good and fine.' She explained.

The group thought it was pretty good, so they closed their deal on the plan.

'Let's make Equestria great again!' Frisk said confidently.

So everypony gathered and put their hoofs (or hands) together. 'Let's do this!' They said in harmony, raising their hoofs and hands.

Chapter 4:Blending in

With all their plans settled, the group of four went out for friendship problems or chances for Frisk to spread friendship on her own, while the remaining five work on a battle plan.This was actually great for Starlight since she also took the friendship lessons with Frisk as well.Not exactly a lesson, but it's just to help Frisk get used to ponies since she has never encountered anypony except Twilight.

'Okay, so what's our plan?' Frisk asked.

'Since we want to make this fast and easy, ,it will be much better for you to get used to the ones that I am more familiar wit because I will probably know how they act or how they will respond to you.' Twilight explained to her. 'Let's start with a simple one, the cutie mark crusaders.They are still pretty young, who we called "Fillies".Should be easy enough.'

So they walked over to their clubhouse.While on their way, Twilight remembered how time-traveling works. 'Starlight, I thought you girls were still supposed to be in 2016, but I teleported like, way back to the 20th century.Shouldn't there be possibly no time difference for you?Or is it the fact that it actually has been forever since I left?'

Upon her saying that, Starlight chuckled. 'Are you serious?Don't you know how time works?Nightmare moon freaking made it enteral night, no daylight cycle or anything!So time literally has stopped, and yes, we are still in 2016.That's why we were surprised when we saw you.'

As they were laughing, the clubhouse was in sight at last. 'I see something,' Frisk said.

'Good, and I think they are in there, I hear some sounds already.' Twilight replied, listening closely.

As they got up, they knocked on the door, came in and saw the three crusaders, discussing cutie marks stuff.As soon as the crusaders saw Twilight, they had the same reaction.

'Princess Twilight!' They gasped.As they went over to cuddle her, Twilight couldn't help but smile.

'We can catch up later,' She said. 'Right now, I have a new friend who's on a mission.'

'Who's came here?Is your friend having trouble getting a cutie mark?' Apple bloom asked.

Frisk showed herself to the trio, and they were obviously surprised.

'Umm, hi, I am Frisk.I came from the human world thanks to Twilight Sparkle.We are pretty good friends now.' She said, feeling shy.

'You look pretty nice, but I don't suppose you have an issue regarding cutie marks since you aren't a pony.' Sweetie belle commented. 'So...What's the matter, princess?'

Starlight cut her off before she could say it. 'We need the power of friendship to help recharge the power of the elements of harmony.'

'The elements are long gone, aren't they?' Scootaloo questioned.

Twilight shook her head. She turned to Frisk and told her to show the crystals.

'Oh my, we could really count on you girls to help us from this terrible event that has happened.' Apple bloom replied.

After a bit of chatting between the human world and Equestria, the crusaders took her as their friend and hoping that Frisk can join them in cutie mark adventures one day.As they were talking, the crystals started to glow, seemingly recharging their magic.

Twilight looked closer and levitated it. 'This is rather interesting...Does that mean we should go find somepony else now?'

'There's no reason not to.' Spike replied.

'Sorry girls, we have to go, we have a long way to go to save this place!' Frisk giggled. 'Thanks for the help, it can go a long way.'

Sweetie belle was feeling a little sad there, but the other two are fine. 'Well, I guess we'll see you around later!' She said.

'Perfect, not only did we manage to do the right thing, but you have at least found out a bit how the world works.' Starlight whispered to Frisk on the way back.

'Alright, where to?' Frisk asked again.

'Alright, we are going on an adventure for friendship, searching far and wide to grow the power of the elements, and help you to understand our world more. Maybe you'll need it sometime in the future.' Twilight explained.

'So what are we waiting for?We have the world to save!' Spike exclaimed.

As they were walking towards the station to go to other places of Equestria,Starlight and Frisk wanted to know each other more. 'This isn't the first time I've been in an adventure like this,' Frisk whispered.

'Well,this isn't my first either,' Starlight whispered back.

'I'll talk more about it on the train ride.'

As the weeks or even months went by,the group continued their search of the cure (no reference intended),what they believed will save a world not once,but twice.They got to meet a lot of different ponies along the way,including Twilight's old friends,Moon Dancer in particular,some of Applejack's other family members,and of course a lot in other places.But one part of the adventure that was the coolest,was their last stop:The crystal empire.

'Next stop,crystal empire!' Twilight said excitedly. 'I've been waiting forever for today!'

'What's all the excitement?' Frisk asked her.

'I get to see my brother and my sister-in-law,the three of us were really close back then,no matter within family or friends.I wonder how my nephew is doing?' She explained.

'Wow,I have been waiting for this day as well actually,I haven't visited my old friend Sunburst for a while.' Starlight added.

'Aaaaaaand,I am so excited to see if the ponies are excited about me coming,since I was literally dubbed a savior of the crystal empire.' Spike also joined in.

'Geez,am I the only one that is not excited about all of this?' Frisk was feeling left out.Everypony laughed after she said that.

Chapter 5:The Crystal Empire

After a long journey,they finally got to the crystal empire.Then it was a bit of walking to the actual place,since the station was a bit far away.The crystal empire is probably one of the most beautiful,yet one of the most fragile places of Equestria.While everything is crystal,if the important relic,the crystal heart gets shattered,it can only end in disaster.

'Surely one of the most beautiful places so far,' Frisk thought.

Upon getting to the castle,multiple guards were protecting the crystal heart,while also protecting the castle as well.But as soon they saw Princess Twilight,they thought that she surely couldn't cause any trouble,thus they let her and her friends in.

'That was for whatever reason easy,' Starlight thought. 'I thought it would be much harder than this.'

Twilight pointed to the throne room. 'Okay,this is the place!' She told them.

'The princess of love...Princess Cadance.And she is right through that door.' Spike added.

In the room,Princess Candance was having a hard time working out a way to help overthrow Nightmare Moon.While the villain didn't discover any of this,the Princess was always nervous when she came to have a look around.She was lucky to keep her control of the crystal empire,even after Nightmare Moon ruled Equestria.

'Cadance...Are you okay?' Shining armor asked her.

The princess sighed. 'If only Twilight was able to come and help us,but one day,she disappeared without a trance.'

'Don't worry,I am sure you can figure something out.'

Just then,somepony came in to tell the princess great news.

'Your highness,somepony came to help you.And I think you know her very well.' He said.

As soon she heard it,she thought of Twilight Sparkle. 'Is this true?'

'Yes,your highness!We just saw her a while ago.Although she is with some other friends.'

The princess chuckled. 'Bring her in then.'

She was right.The group came in,and there stood their old friend.And again,they had the same reaction.

'Twilly!I've missed you buddy!' Shining exclaimed,hugging his sister.

'I finally came back guys,' She replied.She saw Cadance on the throne. 'Cadance!You're here as well!'

Cadance's heart was instantly warmed by her return. 'Do you remember our little dance we did while we're little?'

Twilight giggled. 'Of course I remember.Sunshine sunshine,ladybugs awake,clap your hooves and do a little shake!' She said,both of them doing their dance.

'Wow,they go back a long way,don't they?' Frisk thought.

'We can catch up later,' Twilight said to the two. 'Right now,I've brought a friend to help us do something special.' She revealed Frisk behind her.

As an emperess of her own country,she knows what to do. 'Greetings,your highness.' She said,bowing down to her.

'You can just call me Princess Candance.' Candance replied.

'I am Frisk,the emperess of my home country in the human world.Now,I have followed Twilight Sparkle to here,for refueling the elements and to save Equestria.'

'Aren't they long gone already?You know,since Nightmare Moon took over?' Shining questioned.

Once again,Frisk showed the elements,and again,they were shocked.

'Through friendship,they regain their magic.We can really use your help!' Starlight begged.

'As old friends,we will surely help you with that,' Candance smiled.

'Okay,to make this faster,let's split into two teams.Starlight and Spike,you guys go see Sunburst.We'll stay here,' Twilight explained to them. 'Take half of the elements,and go shake up some friendship,'

As they left,the four started to talk more about the history of Equestria,and more about each other's lives since Equestria plunged into darkness.

'How was life in Equestria when I was gone?' Twilight asked.

'It's terrible,Twilly.Time has stopped working because the moon is staying up there forever.We have to get Celestia back soon.' Shining explained,coldly.

'But on the bright side,since I'd say about a few years ago for your world,I started to secretly work on a plan to overthrow Nightmare Moon,that will probably be useful.' Cadance added,showing them the plan.

'Can we take it back for our discussion on the battle plan?We will very likely need it.' Frisk asked.

'Sure,it's not the best plan in the world,but it will help.'

Twilight thought about Celestia. 'Say Shining,you said we have to get princess Celestia back soon,what happened to her?'

'Don't you see how different the moon is?' He winked at his sister.

'Wait,you don't mean-'

He nodded. 'That's right,the roles have switched places.Now,she is trapped on the moon.'

'There's got to be some way we can get her back,' Frisk suggested.

As soon they were going to discuss more about it,Starlight teleported in with a bang.

'Twilight,we have to go now!' She exclaimed nervously.

'What's going on?'

'She came...Nightmare Moon!We saw her secretly on the streets!'

Princess Cadance was worried. 'Oh dear,as much as I want to talk more,you will get caught if she sees you.'

Thankfully,the crystals glowed brightly and only represented one thing:Their power is completely restored.

'Oh thank Celestia that the crystals got back to full power in time!' Spike thought.

'We'll visit you again when we defeat Nightmare Moon,see you soon!' Twilight said,initiating the teleportation spell.

Not long after they left,Nightmare Moon actually came in the castle.

'Princess Candance!We have to talk.' She said in a solemn voice.

'Y-Your highness,what's the matter?' Cadance replied,worried.

'I have been receiving a number of reports from the royal guard that someone that I recall wasn't supposed to be here has entered our world,with somehow another pony princess,the one I thought had been long gone.' Nightmare Moon explained.

'Oh no,that's impossible!How could you have not seen that?' Cadance faked being on her side.

'Twilight Sparkle...' She said. 'She is the one who could try to lead her friends to stop me.And now,I can see she has returned.Now,princess.I have a task for you;Catch that princess,and bring her to me.If you don't,there will be consequences.'

'Yes,your highness.We will take care of it as soon as possible.' Shining armor answered.

'Excellent.You two are my most trusted allies,get me Twilight Sparkle,and my rule won't be disturbed.' She demanded,shutting the door.

Chapter 6:Stories and Plans

On the way back to Ponyville on the train,Frisk wondered how Twilight's friends came together and found the elements.While Twilight told her many stories about Equestria,this one was one thing she didn't bring up.

'Say Twilly,I was wondering:How did you and your friends meet in the first place?' She asked.

'About that;I have an interesting fact about myself a few years back.That's probably why I preferred not to tell you about it until we became very close friends.The truth is,I wasn't into friendship at all when I was young.' Twilight explained.

'What?Then what happened?You're now the princess of friendship,but what's the thing that helped you to realize that it is such a good thing?'

'Again,it's a long story.'

A few years ago,Twilight was under a tree in Canterlot,reading a book about the two royal sisters.She started to think about an upcoming event,the summer sun celebration.However,she recalled something about Nightmare Moon returning to Equestria many years after her defeat.

'I know I have heard about the elements and all of this before,' She thought to herself.

She ran back to her home,tried to look deeper into the defeat of the infamous pony.She found a book about 'The Mare in The Moon',and when she read it,she found out Nightmare Moon is returning exactly 1000 years after her defeat,which happens to be the 1000th summer sun celebration.She knew it will be a disaster if she didn't warn the Princess about it.But after she sent a letter to the princess,her reply was more different than usual.

'The princess told me to make some friends while checking out the preparations done in Ponyville...But why would she say that?She knows I don't mix well with friendship.' Twilight thought.

But what she didn't expect,was that after making the five friends she still had to this day,it was the key to defeating Nightmare Moon's return.With her knowledge about the elements of harmony,she understood more about the basics of friendship through her journey to the old castle with her friends.After all of that,she realized her position as the barer of the element of magic and friendship,a title that is still recognized by many ponies to this day.

'Who knew that one adventure helped to bring an unbreakable bond between me and my friends?' Twilight chuckled.

'Honestly,I don't think Equestria would have been saved if it weren't for you,' Frisk replied. 'Oh,we're almost there,' She said as she looked out of the window.

As soon they got off,the group dashed back to the castle,hoping to end this as fast as possible.Opening the door to the throne room,the other ponies wasted no time and started to discuss about plans.

'So,was your part of the plan good?' Pinkie questioned.

'Nearly got caught at the last moment,but we're fine.Also,thanks to Princess Cadence,we have a pretty interesting battle plan from her.' Spike explained.

'Awesome,it has all of the secrets of how the castle is guarded!It will be easy to sneak into the throne room this way.' Rainbow thought.

'How are we going to get in there,now that we know what to do?' Starlight asked.

'We plan to attack from all sides,that way we can meet up at the throne room for the battle,' Rainbow suggested. 'Fluttershy and I will go in from the top,since we can fly.Pinkie and AJ,you two are going on the left of the castle once you all go in.Starlight and Rarity are on the right side.And the rest are going to deal with the guards,and then take the middle.' She explained.

'Nice,I'll get to show how awesome I am at combat,' Frisk replied.

'So,no problems everypony?' Twilight asked.After they all shook their head,she locked in their plan. 'Alright,we'll talk about the final showdown,and then we'll attack on the next day.'

Chapter 7:Battle Time!

The day has finally came.The day where the ponies finally overthrow Nightmare Moon.A lot of ponies already know this is happening considering Twilight told the friends they met through their exploration about their attack.After they have split up for their plan,Twilight led the way to the front entrance of the old castle.

'Wow,who knew night actually helped us carry out this plan?' Frisk whispered to Pinkie Pie.

'I didn't expect this either,I'm so excited!' She replied.

'Shh,wait right here,we are gonna strike them guards.' Twilight whispered to everypony.

They emerged from the forest and appeared in front of the castle guards.

'Who has came to here without permission?' One of them said in a solemn voice.

'Somepony's going back to where they belong,' Frisk said with a mischievous smile. 'Twilight,go for it!'

They immediately started a battling spree with the guards,but with Frisk's unbelievable fighting skills,paired up with Twilight's magic,the guards didn't stand a chance.The others came out.

'That was easier than expected,' Applejack said,laughing.

'Stick to the plan,go where you are told to go.' Twilight levitated the sword for Starlight and gave it to her for protection. 'Ready?'

The ponies nodded,and in the castle they go!

At the top,Dash and Fluttershy teamed up to sneak inside secretly.They didn't really have to do much fighting since there aren't guards on the roof.

'Huh,no guards in sight.You can relax now Fluttershy,' Dash laughed.

'It's not my fault I'm not assertive,Dash.' Fluttershy replied,flapping her wing against her playfully.

They found a hatch,and got into the castle from up top.What they didn't expect,they landed right in front of the throne room.

'Sweet,now to sneak in there,wait for everypony else to come in,and let's beat her up!' Dash thought.

Twilight,Frisk and Spike caught up to them,since they were heading in the same direction.

'Convenient you girls landed here,are you ready?' Twilight asked.

'Time to put her to where she belongs.' Dash replied.

They opened the door to the throne room,and finally came face-to-face with the infamous ruler.While she looks surprisingly cool,no one challenges her magic.

'This ends here,Nightmare Moon.' Twilight called out to her.

'Ah, "princess" Twilight Sparkle.I was expecting you.' She turned back to see her friends standing,including someone new. 'Who is this traitor you brought along as well?' She pointed towards Frisk.

'You don't need to know...Because you'll meet your downfall right here,right now!' Frisk yelled back.

As they were talking,the other two pairs came in.

'Surrender yourself,or we will take it by force!' Rainbow shouted.

But the villain only laughed evilly. 'You think you ponies can defeat me!?Think again!You don't stand a chance against me!'

Frisk knew this was the final battle.Nodding to her friends,they started the fight.While Nightmare Moon was overpowering the ponies at first,but the ponies eventually started using multiple attacks,unusual and practical,to beat the ruler to the ground.

After a while,Nightmare Moon was getting exhausted and had no choice.Charging up her magic attack,she immediately tried to kill the strongest one of the team:Frisk.

'Muhahahhahaha!Die you traitor!' She laughed in a loud voice,initiating the attack.

Frisk immediately pulled out her dual swords,surprisingly strong enough to block the attack.

'Wha-What!?Impossible!' Nightmare Moon thought.

'Come on...I can't hold it any longer...' Frisk mustered all her power as much as possible to keep her alive.

The beam caught the group's attention. 'Frisk!' Starlight and Twilight yelled.They dashed over and backfired the attack with combined magic.Stunning the villain,they had a chance to finish her off.

'Come on everypony,we only have one shot at this!' Twilight gathered everypony to perform the rainbow laser attack,the same thing that helped Frisk brought victory. 'I've beaten someone with this once,I will do it again!'

As the elements unleash their magic,Frisk,standing at a side,suddenly had memories going through her head about Equestria.

'We have to get Celestia back as soon as possible.' A voice in her head said.

'She defeated our former ruler...Princess Celestia.' Another said.

She even recalled her own memory of defeating Gromiz.

'To the moon you go!' Her voice said to her.

'No...I need to save her.' Frisk thought.

As the magic finally got to it's potential,it's ready for fire. 'Go back where you belong!' Twilight shouted,firing the huge laser.

'No!!!!' The villain cried as she got blasted to the moon,with some kind of magic fading away.

But,what the group didn't expect,was Frisk running in as soon it was about to open fire.Everypony gasped in horror,especially Twilight. 'Frisk,no!' She called out.But it was too late,she got blasted all the way to the moon,and all she could do was hold on tight in her travel.

Chapter 8:Confrontation On The Moon

Blasting all the way to the moon,Frisk battled the huge force,hoping to at least get to the moon to do one last task.And thankfully,she survived,and it was also lucky that for some whatever reason,she was able to breathe.

Frisk gasped in amazement. 'I did it...I'm on the moon!It's a wonderful sight up here!' She glanced at the planet she was on. 'I still can't believe I survived...I thought I was very likely going to die!' She thought to herself.But not long after she landed,she heard the voices of somepony crying.

'Huh?Who is it?' She walked closer to the sound. 'Princess Celestia?Are you there?I've came to rescue you,' she called out.

After walking for about 10 minutes or so,she stumbled upon the crying pony.She was blue (literally and figuratively),with beautiful wings and a horn.She looked like an alicorn,just like Twilight,but much taller.

'I am so sorry...Tia...Forgive me please...' The pony sobbed.

'Uhm,hello?Sorry to disturb you,but I heard you from miles away,what happened?' Frisk tapped her from her back.The pony turned around,to see a familiar person.

'I recognize you...' She said. 'You were that girl I fought with moments ago,aren't you?'

'Call me Frisk.And,are you Nightmare Moon?You know me,but you don't look like her...' Frisk questioned.But as soon she said that,the pony started crying again.

'Don't call me that!' She cried. 'I was her,yes.But I was consumed by this magic..I didn't want to take it so far...'

'Sorry,who are you?'

The princess dried her tears. 'Call me princess Luna,the princess of the moon.'

'Luna?Were you in charge of the Moon?' Frisk asked.

'Yes,it's a long story to why I became the so called "Nightmare Moon".I was jealous of my sister Tia for her popularity years ago,to the point where I feel like the ponies didn't care about me,since they just sleep during nighttime.I felt so left out I wanted to make it enteral night,and then overthrow her,then everypony will obey me,' Luna explained. 'But now...I realized I was wrong all along.I don't want to be like how I was ever again...'

'Your sister was kinda the spotlight...I understand how it feels.' Frisk comforted the poor princess.

'But you don't,you aren't a pony.You didn't know what happened,and I don't think you understand how I feel inside.'

Frisk sighed,but still smiled. 'Luna,I understand.My home country on my home world was the same case.An evil wizard from my country was jealous of the former king,and while he agreed to work with him,the jealousy of the wizard's heart only grew.And in the end,he declared war on the king,and won.But one thing stood between him and ruling the country forever:That was me.'

Luna was still trying to keep calm. 'But- (sniffs) But why would you follow me here?'

'Through princess Twilight telling me more about Equestria,I understood how important princess Celestia was to this place.I have to save her.' Frisk answered.

'Why will Tia forgive me for what I did?I have done so much evil to Equestria...It was my fault,she won't forgive for what I have done.' Luna was puzzled.

'Trust me,she hasn't seen you in forever.And,you two are sisters.I am sure she will forgive you,you never know.'

So the two wandered around the moon,hoping to find Princess Celestia. After quite some time (about an hour or so),they heard a voice,singing some kind of lullaby.

'Fate has been cruel and order unkind...How could you have hurt me this way?'

'Tia?' Luna thought.They walked closer to see what has been going on.As they walked closer,Luna knew her sister was near,she recognizes her voice.A few minutes later,they found the beautiful and glamorous princess,with a colorful mane.

Frisk was impressed by her looks. 'Wow...So this is your sister?' She turned to Luna.

'Still as beautiful as she was years ago...' Luna cried.But to not ruin the moment,they let Celestia finish her singing.

'The years now before us,

Fearful and unknown....

I never imagined,

I'll face them on my own...

May these thousand winters,

Swiftly pass,I pray,

I love you,I miss you,

All these miles away...'

As Luna continued to watch,her heart was breaking fast too. 'Oh,she still cares about me...I love her so much...' She cried.

'Go for it,make up with her.' Frisk softly told her. 'If you really love your sister,do what you must.'

'Stay aside then,I don't want you to ruin the moment.'

After that,she flew behind her sister.She felt shy to ask for her sister's forgiveness,but it must be done.Tapping her back,she saw her face for the first time in almost forever. Celestia gasped,tears were running down her face.

'Tia?I'm sorry.' Luna told her.

But Celestia didn't need to hear anything.She just wanted to hug Luna so badly,so she did.

'Luna,you finally learned your lesson and came,didn't you?' Celestia cried.

'It's a long story to why I came here all of a sudden.But,all you have to know is that I've came to apologize for what I have done,and I know I was wrong.I was wrong to be so jealous toward you,and I couldn't hold it in that day.I finally felt your feeling of being stuck on the moon alone for so long.I don't want my dear sister to be alone again...Please forgive me and come back.' She begged.

After hearing her words,Celestia was really surprised on how she was so sad that she was gone.

'Oh Luna...' She said as she took Luna under her big wing. 'You are my sister,we are meant to rule together.I don't blame you for being so jealous.I should have listened to your feelings more about me,even if you have bad opinions.But,at the end of the day,both of us have been doing something wrong all along.If I forgave you for what you did,will you do the same?'

Luna smiled.She has wanted to do this for a long time. 'Of course I forgive you.' She said,hugging her sister.

But all of a sudden,Frisk came in and nearly ruined the moment. 'Well done,Luna.I haven't got to know you much,but I'm glad both of you are reunited.' She said,clapping her hands.

Celestia was surprised when she saw her.She has never seen a human on their world before. 'Did you bring a guest,Luna?' She asked.

'Oh,I almost forgot!' She turned to Frisk. 'This is Frisk,Twilight Sparkle's new friend.I know that because I was fighting with her friends earlier and she somehow got to the moon with me.'

Upon hearing Twilight's name,Celestia was once again surprised. 'She came back!?'

'She did,your highness.I expect you haven't seen her in a long time.But how did you know?'

'I did a lot of analyzing to why the elements weren't there while I was trapped here.Thanks to Princess Cadance,I was able to communicate with her through a magic book,that sent messages back and forth.' She explained,showing the two the book. 'Many years later,she reported to me about the missing of Princess Twilight.Then,it all made sense that she was the culprit.'

Frisk was impressed. 'You were right,she did steal them.I talked to her.'

'You did?' Luna asked.

'She even ran into the forest to have some "alone time".' She added.

'We can talk more about that later.Right now,we need to get back to Equestria.' Celestia said.

'What?How!?It's like,miles away from here!' Frisk thought.

'I know what you're thinking Frisk,I have my own ways.Get ready for a ride.'

Frisk hopped up on Celestia's back,and she initiated a very powerful spell to teleport all of them.

'Hold still!I have not perfected this spell,I hope it works!' Celestia warned.

With a bright bang,the trio successfully teleported back to Equestria,safe and sound.

Author's Note

Author:Okay,time out.I know this is very sudden,but I just wanted to tell that I do not own the rights to the song reference I put in there.I had to because I wanted to make it more cool and cheesy.

Alright,sorry for disturbing you reader,you may move on.Time in!

Chapter 9:Returning to Equestria

Back in Equestria, The ponies just woke up after collapsing to the ground when they finished the attack. They see the giant hole in the castle, and knew that everything was finally over.

Pinkie Pie gasped. 'We did it! She's banished to the moon!'

But seeing Frisk suddenly running into the laser, Twilight was nervous. 'Wait, where's Frisk? I just remembered she ran in and got blasted to the moon as well...'

'Nope,nowhere to be seen.' Dash replied,looking around.

'Oh dear...Where did she go?' Fluttershy said coldly.

Suddenly,a vain of light started shining through the room.It was the princess returning!

Twilight walked closer to the light,curious to find what's inside. 'Are you there,Frisk?' She asked.

As she touched it,it exploded and the trio came flying out,with Frisk knocking Twilight back.

'Frisk!You're okay!' Twilight exclaimed,hugging Frisk.

'What happened?I just remembered I was on the moon just now...Princess Celestia used a powerful spell to teleport us...And then,I came back here!' Frisk explained,feeling puzzled but relieved that she was safe.

'Wait,did you say princess Celestia came back?Where is she?'

Celestia came out and everypony bowed down to her. 'Indeed I came back,with somepony else you didn't expect.' She said,revealing her sister behind her wing.

'Princess Luna!' Everypony thought.

'Hey everypony.I'm sorry for what I did for all these years,I just made up with Tia about it.I hope you all forgive what I have done,' Luna said,feeling shy.

'We already have,' Starlight replied.

Princess Celestia was just glad to finally get back,but she knew Twilight has done something very wrong.She turned to her and said, 'Twilight Sparkle,we need to talk.'

Twilight sighed.She knew this was coming. 'I get it,you know I stole the elements,don't you?'

'I received your letter,explain what happened.'

'I stole the elements for a good cause,Frisk's home planet was in danger.I time travelled back to get the elements so I can use them to possibly save her world.But,if it weren't for me doing so,she wouldn't have came to save us all.I met her in our first journey,and with the power of the elements,we saved her country and possibly the world at the same time.Then she asked if I can take her back here and then...' Twilight sighed. 'I guess you know the rest.However,I altered history and made you stuck on the moon...Feel free to do what you must.I am ready for my punishment I should have taken years ago.' She added,with tears dripping down slowly.

Seeing how apologetic she was,Celestia felt bad for her.She thought for a moment,and calmly told her:

'I was going to do what you said,but hearing your story...You deserved to use them.I understand that this was a good thing,and you just helped save the one person who will guide you to save us all...Don't feel guilty,princess.You've done the right thing.'

Twilight dried her tears. 'Thank you,I mean it from the bottom of my soul.' She turned to the others. 'So,what's next?'

'Are you kidding?Let's get the celebration started then!' Rainbow replied excitedly. 'Pinkie Pie,hit it!' Pinkie grabbed her party cannon from out of nowhere and was ready to open fire.

'Whoa,Pinkie!Can we do this in a later day?I'm sure we are all exhausted from that long battle.Let's do this sometime soon.' Frisk warned her.

Everypony burst into laughter.

Chapter 10:A Sad Goodbye

The celebration was held a few days later,celebrating the return of Celestia's sister and herself to Equestria,and this day became the national holiday we all know as 'The summer sun celebration'.This day was when the sun shone the brightest and longest,and starts with Luna lowering the moon and Celestia raising up the sun,and the crowd cheers loudly for the two.

They were about to start,and everypony was excited.As the princesses came out,the crowd cheered with joy for both of them.It was such a sight that both are together again.

'Mares and Gentlecolts,we are gathered here today to celebrate the first annual summer sun celebration.After all that has happened,with time being altered and Nightmare Moon taking over Equestria,this time we are celebrating the return of both me and my sister,princess Luna.' Celestia said in a loud and solemn voice.

As everypony cheered under the moon it was time for the sun to finally rise for the first time in years.

'Go on Luna,you can do it.' She whispered to her sister.

'Alright,I haven't lowered the moon for a while though.' Luna replied.

As Luna slowly lowered the moon,Celestia immediately brought the sun out,and everypony got the glimpse of light for the first time in several years.

'It's so beautiful,' Frisk whispered to Twilight backstage.

'Wait till you see what I do next.You'll love it.' Twilight whispered back.

As the sun reached it's peak and light finally shone over the land,Twilight came flying out with a magical sonic rainboom!Not the real rainbow one,but still really cool.The ponies gasped in excitement as they saw her.Landing without a scratch,Twilight came in for another speech.

'Thank you everypony,it has been a long time since I've came back here,and I'm glad to able to save this place once again.Many of you may have seen me a few times a while back,and I was bringing along someone special.But before she comes up,I just wanted to warn that nothing is wrong with her,I brought her here for just a visit,but nopony expected this!'

Some ponies in the crowd were curiously talking to each other about the special guest.

Twilight saw they were curious,but she smiled anyway. 'Now,I have been talking long enough.Some of you may know her and some may not,but please welcome my friend from the human world,empress Frisk!'

Upon Frisk stepping up to the stage,everypony held back their curiosity and cheered for her loudly.She was pleased and had a big smile on her face.After calming down everypony in the crowd,she give yet another speech before the fun starts.

'Hello everyone,I am Frisk,the empress of my home country,as my friend princess Twilight has told you.Now,I came here for a reason,and it all happened when Twilight and I became friends on our first journey.After we defeated my country's former ruler,we decided to come back here to Twilight's home,and I wanted to get to know more about her world.But what I didn't expect,was the fact I will be joining her friends to defeat Nightmare Moon!Now,although my visit here is coming to a close,I hope to make the best out of this celebration before I return back home.This has been a blast for me and I'm certain this country has a bright future for the years to come.Okay,I have been boring you ponies long enough,so let's get the party started!'

Everypony cheered for her and the celebration has begun.It was a long day,but it was an awesome last day for Frisk.

However,all good things come to an end,and it was time for Frisk,Spike and Twilight to go back to the human world and continue on their reign.That evening,the ponies stand before the trio,to say goodbye.

'I guess this is goodbye,' Starlight said.

Twilight felt sad,but she knew she was going back. 'I honestly wish I could stay longer,but we have our own things to attend to back on Earth.'

'That's right,Twilly. We are important for our country,and I also wished that I can stay longer to know more about this place.' Frisk added,still with a smile on her face.

'I am really thankful you helped to free my true self,young one.You have really proven yourself as the chosen one,as you told me.If only I talked to my sister in the first place,she would've realized my feelings.' Luna said,embarrassed.

Celestia flapped her wing against her sister playfully. 'Oh Luna,you silly sister.' She chuckled. 'But seriously Frisk,thank you for saving all of us.This wouldn't be possible without you.' She added.

Frisk's face turned red upon her praise. 'You're welcome,your highness.' She smiled,shaking her hoof.

'By the way Twilight,I have a spell I have been working on,and I think you guys are going to like it.' Starlight told them,charging up a spell with her horn.

'What is it?'

As she used the spell,nothing really changed.But,her explanation was the really exciting part. 'If I did the spell correctly,you three will forever stay at the same age,so now you don't have to worry about growing old again!' She said excitedly.

'Wow,you're amazing Starlight!' Spike replied.

'Before we go,let's have one last picture together,shall we?Just for Twilight to remember you all.' Frisk suggested.

Everypony nodded,and gathered for a picture.Photo finish was obviously the one doing the photo-taking part.

'Three,two,one!' She called out,taking the photo.

At last,after a tearful farewell with everypony,Celestia was ready to use the teleportation spell to take them back to Earth,thanks to Twilight guiding her target.

'Are you ready,Twilight?' She asked.

'Ready when you are,' Twilight replied.Turning to her friends,she went over for one last group hug with them.

'Don't miss me girls,I'm sure we'll be back together soon.And this time,I really mean it.' She told them,shedding a tear.

'We love you Twilight!' Pinkie said.

'We will always remember you,sugarcube,' Applejack was crying as well.

Turning back to Celestia,she was fully ready now. 'Okay,let's do this!'

As Celestia was charging up the teleportation spell,she still looked at her friends.

'Come back soon!' Rarity cried.

'Our bond will forever stand as one,don't forget us!' Rainbow shouted,in a good way.

'We will be waiting for you!' Even Fluttershy wasn't so quiet in this situation.

Starlight was almost too shy to say farewell. 'Never say goodbye,Twilight!'

As the teleportation spell stroke them,Twilight was crying,but they were happy tears. 'Goodbye,my friends...' She thought,as the teleportation spell finally successfully teleported them back,and they disappeared without a trance.

Chapter 11(The End):Under the moonlight

The spark from the spell had appeared on a hill,and they landed right there.It was a rocky landing,but it was great to be back.

'It worked again!We are back now!' Frisk exclaimed.

Seeing the buildings nearby,she knew it was Britannica they landed back on. 'Yep,it looks like we are home.' Twilight replied.She turned to Spike. 'Oh,and Spike?Do you mind if you go back to the palace now?We want some time...Alone,' Twilight said,her face turning red.

'I guess I don't mind,' Spike answered,and he left the two alone,under the tree that was under the night sky as they got back during the night.

The two lied on the soft grass of the hill. 'Twilly,do you have something to talk to me?' Frisk asked.

'I have a confession for you,' she replied. 'Through these past adventures,you have grown a lot in understanding friendship,and I am glad I met you.The day you resurrected me,I was glad I finally got out of the afterlife,and was able to see a real chosen one on my side.Sure,I have been resurrected a few times before emperor Zebulon told you all about the secret of the cure,but meeting someone like you,it doesn't happen everyday.'

Frisk's face was turning red too. 'Uhm,thanks,I guess.You have shaped me into the person I am today,I couldn't thank you more.'

Twilight smiled as well. 'Well,it's time that we head back,we have a lot of stuff to do.'

'We already had a long day...Can we spend some time here?' Frisk asked,showing her friend a cute face.

'I guess we could,we're not in a hurry.' Twilight felt a little embarrassed.

'Thanks Twilly,because I want to say something too.'

'What?' Twilight was curious.

Frisk was acting strange at first,but she said, 'This sounds weird but...I feel like we are friends destined to be,I just hope you will always be my best friend.' And as awkward as it is,she lightly kissed Twilight on the cheek.

Twilight giggled a little. 'Frisk...You are so sweet,of course I'll be your best friend.'

'Do you promise me?' Frisk asked,giving Twilight the 'promise finger'. 'If you do,link your pinkie finger across mine and we'll make our promise.'

Just for the sake of this promise,Twilight turned into a human. 'Best friend promise,' She said.With their fingers crossed,they both said:

'I promise you,I will always be your best friend and you will always be my best friend in my heart.'

Twilight smiled as they let go. 'We'll be best friends forever,won't we?' She said,putting out her hand.

Frisk felt a little shy. 'We will,Twilly.Nothing can break our friendship,the same with how your friends were to you.' She took her hand.

'Come on,you can do better than that,' Twilight said,punching her playfully.Frisk chuckled.

'If you don't mind...Bring it in then,' She replied,bringing her close with her arm.Twilight felt a little odd but her heart was feeling so warm.

'Haha,you too Frisk,come here.' Twilight laughed,doing the same.

The two friends laughed and played on with each other under the moonlight.

**The End**

Author's Note

Firstly,thanks for reading this story till the very end. :)

About the story:During the working of my original version of this story's prequel,Quest For the Cure,I added a very significant my little pony reference.Then,I thought it would be cool to 'ponify' the story after the original has been completed(As told in chapter 1).But then,I had a cooler idea:I should start from scratch and make a sequel.
Surprisingly,it only took less than a week for me to finish the story,can't believe I finished so many chapters in the past two days :derpytongue2: Anyway,I can stop this little 'series' now,but you'll never know what I come up with...In fact,I have a cool idea for my third story of the series.But,if I plan to do it,I have a mini story coming up that will link up to it...Be sure to keep on the lookout for that!
