Everyone dropped back to the ground, feeling exhausted but great and proud. As Frisk slowly dropped back down, she was very proud of herself. Everything in the past years or even decades... finally put off to rest.

'Is he dead?' Celestia asked.

Frisk went forward. 'I'll go and check.'

When the dust from the blast had cleared, she slowly went forward to check. In the middle, no sign of his body was found; just a pure, black and dark heart on the ground.

'I can't believe it... I did it again!' She thought. 'Hey everypony, look what I have found!' She called out to the others.

Everyone was stunned by this heart. 'Was this his heart?' Twilight asked. 'I have never seen it before...'

'Amazing... We killed him!' Nathan exclaimed. 'But, what do we do with this?'

Suddenly, the heart started to glow, and dark magic was slowly wrapping around it. Slowly, it left Frisk's hand and started spinning quickly.

Flurry heart was worried. 'We should probably not touch that... Just like how I accidentally destroyed the crystal heart that time.'

'Flurry, this isn't the time to joke around!' Cadance said nervously. 'It's may actually be-'

But before she could finish, the dark magic grew and grew. Then, everypony started to get pulled in by something. The heart is not just a heart with dark magic... It was a miniature black hole!

'Wait, why are we getting pulled in?' Luna was scared and wanted to cuddle her sister.

Frisk knew what's going on. 'Uh... New plan everyone.' She slowly backed away. 'Run!'

The entire group ran for their lives, and as the black hole grew bigger, the stronger it's gravitational pull became. As the group ran faster and faster, they slowly managed to escape, one by one. However, Frisk wasn't so lucky.

'Ahhh! No! Not now!' She was behind them all, getting slowly pulled in by the black hole.

Twilight saw what happened. 'No! Frisk, come back!' She ran to her friend and took her arms, trying her best to pull her out. She wanted to ask the others but was afraid they will get caught by the black hole. Plus, Nathan is the last one that was even close to the two, the others all successfully ran away.

'Quick, in the portal everypony!' Celestia signaled, opening a portal to Equestria.

'What are you doing Nathan!? Run away!' Frisk yelled, seeing he was tempted to go back for her.

He thought for a bit and was a bit depressed. 'Oh Frisk... I'm sorry.' He said as he charged up his powers, and flew away quickly.

Leaving the two alone, Twilight was struggling to pull Frisk out of the pull of the black hole. Frisk knew this is the end for her, she couldn't possibly get away. She thought about all the times she had with Twilight, and couldn't stop crying.

She smiled. 'Here we are again... In the worst situation possible.'

Twilight tried her best to continue pulling through. '(Grunts) I won't lose you. Not this time.'

As they got to a safe place, Frisk didn't follow her friend. 'I have a last resort to save you all.'

'Huh? What is it?'

Frisk saw the expanding magic. 'If I unleash all of the magic I got from that rainbow potion in there... I can get rid of that black hole, and save all of you.'

Twilight pulled her friend's arm. 'No! Don't do it, you'll die!'

'It's the only way.' Frisk said. 'If nothing is done, this black hole will only keep expanding forward, and soon... all of the solar systems... Equestria, everything... it will get consumed. I can't tell how strong it is, but I believe even with your planet so far away, it can reach there very soon. Terminating it is our only option.'

Twilight was crying. 'No... I can't lose you again... I have lost you for so long...'

'I know you don't want to loose me... But why?' Frisk was getting nervous about the black hole.

She had a confession. 'That's because... as your friend... I...'

Frisk knew what she tried to say, and hugged her. 'I understand. You love me, don't you?'

'(Sobs) Exactly! Please don't leave me alone again... I can't stand being alone without you anymore...' Twilight hugged Frisk tightly.

Even in this situation, the two sang with each other for one last time.

'Leave me be... Say goodbye...
You can't help... Why must you try?
Why must you... Stay with me?
Your battle's won, go with your family!'

'It's not fair to be alone,
After what you've been through.
But if it's the only way,
I will not stop your plan.'

'I'll keep trying to reach out,
I won't abandon you.
Determination fuels me,
I will go save you all.'

'I will give you my comfort,
(I don't need...)
because it's clear to me...
(Your comfort...)
Fighting won't solve anything.
(If you can't help...)
Please, I won't let you go!
(Just let me go!)'

'I will stay here by your side,
(Don't worry...)
I know it's frightening...
(If I cry...)
To think that you might now leave,
(I am ready...)
But my friend, that is why...
(To say goodbye...)

I will keep you in my heart,
(Don't stay here...)
And hug you tight and close.
(You will die...)
We will be together here,
(Your battle's won...)
Until it's safe to go.
(Go live on happily!)
I'll always be by your side.
(Forgive me...)
I know it's frightening,
(Say goodbye...)
To think that you might now leave,
(You're the last light...)
but my friend, that is why...
(I'll ever see...)'

'I will keep you in my heart,
I won't abandon you.
Our friendship will pull us through,
Until both of us die.
I will never forget you,
I love you so, so much...
Time has come for us to say...
"Farewell, my best friend."
We'll always be together,
And both hug tight and close,
We will never split again,
I'll never let you go...'

They both let go of each other and looked at each other for the last time.

'Goodbye, Frisk.' Twilight said, running away.

Frisk smiled as she left. 'So long, Twilight Sparkle.'

She turned to the mist of magic and immediately held back all her tears.

'Zebulon... If you want to force me to die... I will die with you.' She thought, flying into the middle of the dark hole.

As she flew in, she tried her hardest to find where the source is: The soul of Zebulon. Once she shatters it and the power of her rainbow spell can overpower the dark magic, it will all be over.

She finally found it, and held in front of where her heart is, and started to unleash the magic inside of her. She can hardly bear the pain she is suffering. As rainbow magic shone in front of her eyes, she was about to cast the spell and said one last thing, smiling.

'I love you... so much... Princess Twilight.'

And with a deafening bang, the power was unleashed all at the same time, sacrificing Frisk in the process, and shattering the dark soul. The power was enough to defeat the dark magic, and she collapsed to the ground, resting in peace.
