It is not warm, it is not cold, it is absolutely freezing. Ice-cold would be a more merciful atmosphere compared to where she was now.

Atmosphere, she loathed that word now for there was none here.

There was nothing.

She had no body, no eyes to see with, no ears to hear with, and no hooves to walk with. For an unbearably long time there would be nothing to taste, to hear. All she could do was feel: hate, sorrow, cold, pain, and fear.

It is very dark that is one thing she knows in here. She can still remember.

She remembers everything so well, which is why everything hurts so much now. She can feel that she is not quite herself, she could feel time passing but not how much.

All it had taken was one spell and everything - all the pent up emotion - was unleashed. The magic was all her own, from her and made by her, but the likes of it had never been seen before. Like the northern king's it was quite clear something happened to her mind but to what extent?

What would be recorded by the scribes in the coming ages? That she was two? No, that was not so. She was still one pony hurt and twisted between all those layers of neglect and sadness.

She did not even look the same anymore, but it didn't matter when she was sealed within this distant and lucent satellite.
She could not see any of that light.

This was the closest thing to nothingness she was likely to know.

Discord was petrified by the Elements that they unearthed from the ruins of a much older castle beneath their own dwelling in the Everfree. Before they found those stones and their once-friend had his last laugh there was another sealed in a place, but they had used their own magic for that and he had more than Discord's last laugh, for an entire city was lost.

That northern waste was a sun-scorched and sand bound desert compared to her here and now.

There was no home here and was there one in that forest, the ruined castle both Celestia and herself barely remembered. She destroyed the atrocious edifice that replaced the old place they had walked away from together as happy-go-lucky fillies.

There was so much time to think up here in the sky. She could only think since she knew not much else other then that time was passing as it always did. But what did it matter to an immortal like herself?

It didn't.

She cared not that time was passing or what was done what that time because she was alone here, where it did not matter.

After all, she could do nothing but think and ask questions.

Would she be like this forever?

'This', of course being her not-quite herself transformation, she had snapped after all. That statement was simple even if nothing else was.
She was not even sure if the spell or whatever strange and awesome she performed - as horrifying as it was - could be reversed. She was sure there was regret in there somewhere but not specifically what it was for.

Most of all she was well aware that she couldn't quite control herself anymore.

Her own thoughts were conjured in brief, angry, and vengeful snaps. The mental bite's wound lingered long after the initial realization. Always, she asked how were these hers? Her bewilderment was never addressed for it there are only questions, there can never be answers.

The resentment never faded and thrived once again in this lightless place.

Nothing was dim for every second of this turmoil occurred within the mind of an immortal where 'fade' is only the slightest possibility, not as mortals know it, and 'forget' is utterly impossible.

Maybe all the sorrow was for herself, who else would need it?

There was no fire or warmth here. She could not laugh or cry, all was mirthless. However, this stopped nothing - her wrath was more than a mere candle, it was a cold and biting fire that inspired her but never drained. Her bitterness was not wanton or foolish.

From this place her magic essence would slowly reach out with invisible strings seeking the power she needed, the power that was her birthright. Celestia could not block this gradual occurrence no matter how much she tried, if she noticed at all since powers lie elsewhere and who is to say she remembers her all the way up in the sky?

Up here, the daytime of the world below was masked in the sun's light, oblivious to the machinations of the heavens above where all is darkness and the careful workings of the banished princess make no fault as she moves the threads that guide her fate. She uses her currently sealed and finite power to secure her hope of release.

Ever so slowly, it begins and the stars will aid in her escape.

This chapter here is the original draft. The second part was added later. I suppose that you could just read this one, if you really wanted to... please don't
