As the portals opened up and energy connected to the vault and activated the lock, our heroes looked at the set of portals.

Wondering what they had to do, Tails and Twilight began to discuss ideas on how to solve this issue and what connections these portals have with the locks. Unfortunately, Sonic and Rainbow dash began to get impatient as Rainbow was to complain and said, "Come on. How long does it take to say 'let's explore the portals' anyways?"

Twilight began to get annoyed. If there was one thing that annoyed her, it was a complaining Rainbow dash. "If you MUST know, we're discussing if these portals are safe to travel through. AND deciding what's the best course of action to do it in. We don't want to risk going into these portals recklessly, right?"

Rainbow dash then remembered what she meant and immediately shut upped as Tails said, "I've done a scan of the portals and discovered that they ARE like the portals as before. And that their linked with the vault, like a security system."

Twilight continued to elaborate on Tails results and said, "There's also the fact that behind each portal is a sort of guardian. Defeating it will Cas not only the portal's link to the vault to break, but also release a key fragment that will combine to create the key needed to open the vault see what's behind the door."

Everyone then nodded as Sonic began to say, "Alright then, now as for who gose where -" Knuckles then interrupted Sonic and said, "Guys, I sence the Master emerald behind one of the portals!"

This causes the mobiun heroes to be alert as Knuckles began to charge at the portal, but Spear and Sonic stopped him as Spear said "Whoa there knuckles! I know getting the Master emerald is important, but we don't know which portal it's in or what we're gonna run into in there. How about whoever finds the Master emerald, brings it back here for safety, ok?"

Knuckles begrudgingly nodded as The equestrian heroes began to question what he meant with Twilight asking, "Ok, we've heard you guys mention this "Master emerald" a few times already. But I gotta ask, what IS this Master emerald your talking about?"

Sonic and the others nodded to each other Sonic said "Well, I guess it'll go easier if we explained what it was. But in order to understand it, well have to first tell you about the Chaos emeralds first." Twilight looked confused and asked "Chaos emeralds? Are they connected to the Master emerald?"

Sonic nodded as he said "Wanna start us off Tails?" Tails nodded as he began to explain the Chaos emeralds to Twilight and the others. "The Chaos emeralds are seven gems of unlimited power. They have been in countless legends, myths, and properties ever since history was first recorded. Nobody has found out who made them or why they were created in the first place. And everytime we learn something new about them, more questions about them surface."

Knuckles then decided to explain the Master emerald as he was it's guardian. "As for the Master emerald itself, from what I've know about it, I've learned from the tales and writing left behind by my people. The Master emerald has been around for just as long as the Chaos emeralds, possibly even longer. It was created for the sole purpose of enhancing or neutralizing the Chaos emeralds power. And the Master emerald itself has infinite energy itself. And as the guardian of the Master emerald, it's my duty to protect it of being use for evil intentions."

Amy then picked up where Knuckles left off, "The Chaos emeralds can be used for any number of things. Like powering up machines for examples. And they also other powers as well. Like teleporting, stopping time, time travel, traveling between dimensions,healing a person-or a pony's injuries, resurrecting the dead, and even empowering themselves with Chaos energy. The possibilities are limitless!"

Spear then continued on to a critical part of the explanation. "However, their most legendary capability is that they can turn the welders thoughts into power. And the emeralds are also somewhat sensitive. And can sence the if the user is good or evil."

Spear then brought a chalkboard (thanks to Discord), and continued to explain his section of the emeralds. "Depending on the thoughts of the user, they can assess different powers of the emeralds. If the user has good motives with positive emotions, they can assess light chaos energy. But if the user has bad intentions with negative emotions, they can only assess negative chaos energy."

Spear then closed his eyes and said "However, that's only scratching the surface, And other anomalies can happen too. For example, if someone uses emotions like anger or sadness around the emeralds but has a strong heart to control the power, they can use dark chaos energy. A strong heart is CRITICAL to keep your mind in check, Cas even if your using positive emotions but your heart becomes corrupted, it'll turn you into a corrupted and mindless monster. But thankfully, that last example about corruption doesn't happen often."

Sonic then took over after seeing Spear get kinda winded on explaining the lore on Chaos energy. "And all on that can happen depending on your mastery on controlling the emeralds and their power. And with one emerald, the user can wield unlimited power. But they said that if some gathers all seven chaos emeralds together, a miracle happens, and the user can also weld ultimate power."

Twilight and the other equestrian heroes were amazed at what they heard. They never could have imagined any artifacts with that much power. However, Rainbow dash then thought of something. "Hey Twilight." Twilight turned to Rainbow dash as she said "Those Chaos emeralds...they kinda sound like the Elements of harmony, don't they?"

The mobiun heroes, except Spear, were confused about what they were talking about as Amy said "The Elements of harmony? What are those?"

Twilight, having the most knowledge of the Elements, thought she was the best one to explain what the elements were. "Well...Since you guys were kind enough to explain what the Chaos and Master emeralds were, it's only fair that we explain what the Elements of harmony are."

Twilight then prepared a speech on the Elements of harmony. "The Elements of harmony are six gems that contain the greatest magic that pony kind has ever seen. No pony know who created them, but there purpose is to protect the harmony between pony kind. The Elements are made up of the six elements of friendship. And each of us are the manifestation of a element."

Twilight then pointed ar Rainbow dash and Applejack and said "For example, Rainbow dash is the Element of loyalty. And Applejack is the Element of honestly. While I'M the Element of magic. And the rest of our friends are Elements too. The Elements of laughter, generosity, and kindness."

Twilight then continued to explain the lore on the Elements saying "Before the six of us found the Elements, our rulers Princesses Celestia and Luna, used the Elements in turn Discord to stone when he ruled Equestria." The mobiun heroes looked at discord as he said "Yes, Yes, we got that part, but I'm reformed now. It's not like I plan to try again or something like that."

Twilight cleared her throat and said "But after that, The princess ruled equestria together and returned balance to it. With Princess Celestia, rising and setting the sun. And Princess Luna, rising and setting the moon."

The mobiun heroes were surprised at the mention of the Princesses power to move the moon AND sun on there own. That was a impressive feat.

Twilight then closed her eyes as she continued the story. "However,during their rule, Princess Luna grow jealous that ponys adored her sister's sun while her moon was shunned by sleep...so she threatened to let the night rule forever, till princess Celestia used the Elements of harmony to...to banish her sister in the moon for a thousand years."

The mobiun heroes were surprised and felt bad that Celestia would be forced to banish her own sister to the moon. But Sonic felt especially bad for Luna. Her jealously caused her for be imprisoned for a thousand years. He couldn't imagine imagine himself having to endure that kind of punishment away from his friends like that. It actually reminded him of a certain wizard he knows that he recently met.

Twilight opened her eyes and smiled and said "Thankfully, after a thousand years passed and Nightmare moon returned, my friends and I found the Elements of harmony in their old castle and used them to free Princess Luna from her jealousy, anger, and the nightmare that had trapped her for centuries. Now, the six of us stand as the new Element welders, ready to defend Equestria from any danger."

Sonic and the others were surprised by the story that the Elements had with their lives. And hearing a bit about the Elements, Tails began to have a interesting theory. "Twilight, when you and your friends use the Elements, dose it feel like that there...alive in a sence?"

Twilight began to the moment that she and her friends first got the Elements of harmony all that time ago and remembered how they seemed like that they pulse with life when they first used them. "Well, it definitely felt like they were alive at some ponits...why?"

Tails began to think and said "Well...if our worlds have connections with each other with similarities...it MAY be possible that a seventh element of harmony is out there somewhere."

The equestrian heroes were surprised at Tails threoy. A seventh element of harmony? How would that be possible? Spear then thought about, and it made sence. "I don't think Tails theory is too far off. If we didn't find the seventh chaos emerald till our adventure in west side island, maybe we missed something at the castle of the two sisters?"

Twilight began to think about this. Was it possible that they missed something in the castle? "Sonic, do you mind waiting here while I do some research? Spear, Spike, and Tails, you come with me. We need to investigate this theory."

Sonic nodded but then asked "Mind if i tag along? You might need a extra pair of hands to help find what your looking for." The five of them then made their way to Golden oak library, while Knuckles, Amy, Rainbow dash, Applejack, and Scootaloo, waited by the portals for them to return.

As the five of them arrived at Golden oak library, which has more of its color back than before and Twilight immediately got into her 'research mode' and began to look for info to support evidence on a seventh Element of harmony. "Spike, can you hand me the book 'Equestria's myths and legends'?"

Spike gave a playful salute and said "You got Twi!" Spike began to look around for the book and gave it to her, "Thanks Spike. What would I do without you?" She nuzzled his cheek with her own as Spike blushed. It had been awhile since she's shown THIS much affection to him.

Sonic then decided to poke around the library and see what books they have. He eventually found a book with a cover of a tan Pegasus with a Indiana Jones looking hat on her. Twilight looked up for a second, smiled and said "I see you found one of my daring do book's Sonic. If you want, you can read them. I think you would like them. There's full of adventures you might like."

Spear's ears Twitched when he heard Daring do and said "Did somepony say Daring do? Oh I love that book series! Sonic, you HAVE to read it! It's really good!"

When Twilight saw Spear geek out as he began to show Sonic the Daring do books, she smiled. She remembered when she introduced him to the Daring do series ànd how absorbed he got into it. The two of them, along with Rainbow dash, would get together and talk about her newest books, Daring do theories, and hoping one day go to a Daring do convention together. Even on days when Scootaloo was on a sleepover, she and Spear would cuddle together with a Daring do book. She blushed remembering the softness of his fur on hers.

"Eques to Twilight. Are you there?" Spike snapped his claws to get her as Twilight snapped out of memory lane blushing at a smug Spike as he said "Your thinking about you and Spear cuddling near the fireplace again, are you?" Twilight blushed and said "S-Shut it Spike! I don't want him to hear us!"

Thankfully, Spear didn't hear them. In fact, just like Twilight, he was in full on research mode. After hearing more about Tails theory on a seventh Element of harmony, he actually began to wonder, are the Elements of Harmony are this world's version of chaos emeralds, is it possible to unlock the full capabilities of the Elements with chaos control? The thought of all that potential got him extremely excited to say the least.

Tails was intrigued by all the books on magic and wondered how magic worked in this dimension. He'll have to ask Twilight on the details on the basis of magic later on.

Sonic, after reading and liking the daring do book, began to explore the library and found a door that lead to a underground lab. He then Said "Yo Tails! Look at this!"

Tails then walked to the door and was in awe at the technology in the lab. While it wasn't as advanced as his lab back at home, but was still impressive since this world didn't look like it was incredibly advanced, technology wise. "Wow! This lab looks really cool! Is it yours Twilight?"

Twilight walked over to the lab as she saw Tails geeking out over her lab. She smiled and said "Well yeah, it actually is. When me and Spike first moved in, it was only a basement for extra space. So, with some connections from cantrlot, I managed to set up the basement with some of the most advanced equipment I could find and make this lab."

Tails was all giddy and then asked "You know Twilight, as impressive as this lab is, maybe I can help you improve on it. Do you mind if I add a 'Tail spin' on it?"

Twilight, while rolling her eyes on the pun, smiled and said "Sure, but maybe after we finish our research on a seventh element of harmony. But, to be honest. I'm kinda wondering if it's a giant-"

"Sorry to interrupt Twilight, but what's with the pile in the corner over here?" Sonic then pointed to the pile in question and both Twilight and Spear realized what the pile was. They turned to a very nervous-looking Spike as he smiled awkwardly.

"Spike...is that the pile of stuff you hoarded during your greed spurt?" Twilight looked at her little brother with a disappointed face as she stared him down.

Sonic and Tails were confused at what Twilight was talking about as Spear filled them in. "See, it was Spike's birthday and it was the first time he celebrated it with friends, so we kinda gave him alot presents, not knowing that dragons are greedy by nature."

He began to feel guilty as he was apart of causing his pain in the first place. "So, he began to subconsciously hoard stuff due to the sudden greed and became a giant dragon and almost destroyed ponyville."

Spear then smiled and said "Luckily, our friend Rarity, somehow managed to get to the real Spike and helped him to return to normal. Thanks to a act of kindness he did for her earlier that week."

Sonic and Tails were surprised by the development of this. They definitely weren't expecting something like that. Tails then asked "So, what WAS the act of kindness that helped him snap out of it?"

Spear chuckled and said "See, Spike was aging a gem, dragons eat gems by the way, for his birthday called a fire ruby. It's a ruby in the shape of a heart."

Tails looked confused as Spear said in the shape of a heart. "Yeah, I don't know the geology of Equestria either."

Spear continued to explain and said "Long story short, Rarity came by and was really enamored by the gem, Spike saw it and decided to give it to her instead of eating it himself."

Sonic then manged to put two and two together and said "Was it because he has a crush on her?"

Spike overheard what they were talking about and blushed, said "I-I was just being nice, ok?!"

Twilight remembered that day and she admittedly felt bad for him. She remembered that he was so excited about eating the fire ruby, only for him to give it away. She has tried to find another one to give him, but she hasn't been able to find one. She wondered how Spike managed to find one in the first place.

She then turned back to Spike and asked "Spike, why do you still have some of that pile that I asked you to return to the ponys you took from?"

Spike sighed, as he knew that he was gonna have to explain himself one day. "Well, remember when you told me to return everything I took from everypony? Well, I did. And everypony was grateful I returned their stuff. But..."

Spike began to look sad and said "Some of the ponys refused to accept their stuff back. Some of them said they already replaced their belongings...while others..."

Spike didn't want to say it, but he HAD to explain why the pile, while much smaller, was still there. "There were ponys that were scared of me. And even angry at me for taking their things and accidentally destroying their homes. They wanted to run me out of town like a wild animal. I even thought that...Is it even worth staying here anymore?"

Spike's reason suddenly became clear to her. It also explains that, despite having been treated like a hero, he still seemed like he was holding on to guilt. She saw Spike trying to hold on to his tears as the memories returned from that day. Twilight then hugged him to try and comfort him. Letting a few tears fall as her heart breaks for her little brother.

Sonic, Tails, Spear felt bad for Spike as they remembered how they felt when they first encountered humans, other then Spear's adopted family.

After a few minutes of comfort, they continued to look for existence of a seventh element of harmony, when Twilight then realized something. "Sonic, you and the others seem to be really knowledgeable about the emeralds, right?"

Sonic nodded as Twilight then asked "Then I have to ask, how DID you and the others come to know about the Chaos emeralds and Master emerald?"

Sonic then began to tell the story of how he and his friends first discovered the Chaos emeralds. From their first adventure on south island, to their adventure on north star island. And the stories fascinated and surprised her.

Hearing that the emeralds helped to start their friendships, just like how the Elements of harmony helped to form her friendship with Rainbow dash, Applejack, Pinkie pie, Fluttershy, and Rarity.

She was about to ask what when Spike suddenly said "Ummm guys?"

Spike then pulled out a round rock with a gem marking on it. Sonic and the others wondered what it was, but Twilight was shocked at what it was. She recognized what it was. "Spike...where did you get that?"

Spike then looked at the pile and said "I found it after looking through my "Hourd" and I thought it was important."

Twilight then had a stary look in her eyes, and hugged him saying, "Ohhh Spike your amazing! You found it! YOU FOUND IT!"

Spike blushed at the hug and said "Twilight, what's going on?!" Twilight then kissed his cheek in excitement saying "Spike, I don't know how, but you found the lost seventh Element of harmony!"

Spike's eyes widen as he said "Seriously? Wow! How did i find it? Or, WHERE did I find it?"

Twilight then let go of Spike and put him on the floor. Happy that the element was found. Spike then began to wonder, "But...how DO we activate the Element? Or should I said, Twilight, how DID you and the girls activate the other Elements of harmony in the first place?"

Everyone began to think of a way to achieve the dormant Element, till Spear thought of a crazy idea. "Why not use the Master emerald's power to activate the element? I mean, if we're right, and the Elements of harmony ARE Equestria's version of Chaos emeralds, then the Master emerald SHOULD resonate with it."

Twilight WAS a bit concerned about using a unknown magic to activate a Element of harmony, but Sonic and Tails actually agreed with his theory.

Tails began to explain "I think Spear has a point! If The Master emerald can synchronize with the Element of harmony with someone who it thinks is worthy, then the Element SHOULD come to life. And find it's rightful bearer."

Sonic then casually put his arm around Twilight and said "Trust me Twi, things will work out. And if the Master emerald can't connect with the Elements, will find another way. You just gotta believe in the unknown sometimes."

Twilight then remembered when she tried to understand Pinkie pie's Pinkie sence, but could never understand it, despite all her attempts at studying it.

But Sonic somehow made her think that, it could be possible to trust in something she didn't understand. And it enforces her choice on to learn more from Soinc about friendship.

The group then left the library to meet up with everyone with the-soon to be awaken-seventh Element of harmony.
