Prologue:
The world around me is small, cramped. At least compared to the one I used to occupy. This one is like a bubble, contained and confined to itself, though it does hang off the other. Or, rather, it hovers near the other one, its plane close to but not connecting with its counterpart. Ah, the glories of physics and its theories.
As much as contemplating my surroundings amuses me, which is very little, I have greater things to think about. My escape from said captivity. And what to do about those who will oppose me when I am free. I open a window from my place to the other, and find exactly who I want to find.
My mad brother, interacting with those gods forsaken ponies. He's been accepted by them and truly accepted them recently. I watch what he does from time to time; it amuses me. For, not only is he mad, he is delusional! He thinks he's found solace in friendship with the tiny equines, when he's only been truly tamed. I hate him for his weakness, for he has acted against me before. He aided our other brother and his mare in their attacks against me when I revealed I no longer wished to work for them. I growl in remembrance.
I also remember how, before he wiped his mind clean, he called into existence two ponies who would aid him when I eventually returned. That time is coming soon, and I have been monitoring them as well. When they were young, I sent projections of myself to them, and attempted to break them before they could stand up to me. My power was so low, then, that I could do little more than terrify the one with nightmares and visions of pain and decimation and remove the wings from the other when she was still unfinished. Discord had put protective spells around them, but more on the male unicorn than the female pegasus, or would-be pegasus, rather. That is why I could only torment him, rather than take his unicorn magic in the womb. My projections lasted for only their foalhood years, and they only affected the unicorn, and then I decided I would hold onto and grow my remaining energy to escape my prison.
The ponies of Equestria do not know it, but their anger feeds me. Their battle lust fuels my magic. Their most recent years have provided me with almost all that I need. Soon, I will be able to interact with their world in much more tangible ways… which will only serve to fuel my magic even more.
I look at my brother, pulling strange pranks and stranger faces for the amusement of the ponies. His body is reminiscent of my own. I wonder if he based his form on me, after I left him alone on the mortal plane. Or maybe it was that last spell I leased on him… His form is more chaotic, as fits him, than mine. My limbs match each other, as do my horns. Similarly, my body is not segmented, though it is very, very long. He has bad posture, but I suppose that is not so important. I look at him, and I almost pity him. He has aged poorly, slightly, but poorly. He is insane, but I can see behind those crazed eyes exhaustion, misery, loneliness. Now that he knows friendship again, part of him can recognize that he missed it, although he only thinks he was missing it in that he never had it. For all that his memories are gone, truly eradicated, his fragile heart knows something. But I do not pity him. I have gone for longer with less, and I have made do perfectly well alone.
No, I cannot pity him, only hate him and wish him a terrible death. A tragic, drawn out, humiliating death. Him and his children of fate. I desire greatly to know why the unicorn had greater protection around him and why the female suffered. I suppose as he is dying, my brother, I can ask him. If they oppose me, I will make their deaths far more agonizing, but if after a warning they back down, I shall make it less so. I laugh. Their options are great pain and greater pain, and that amuses me. They are cornered and they don't even know it.
I release the window and relax backwards into my space. I conjure a weakly structured, at least on a molecular level, couch on which to recline. There's so little matter here for me to manipulate. But it serves my purpose well enough for now. Soon enough I'll be in the mortal plane, where I can manipulate so many things, so much more than a thousand handfuls of atoms. Soon, ponies, animals, plants and civilizations alike will be my puppets for the playing with. I'll send the world crashing down around their ears. I'll set off tiny nuclear explosions and see what sort of monstrosities climb out of the fall. I'll take the bratty princesses, my abominable nieces, and strip them of their magic so that they are little more than newborn foals and I will kill them as slowly as I shall kill my brother and his weapons. I will breed diseases of horrible, horrible pain against specific mixbreeds of ponies, and watch as the nation scrambles. I will do so much to them.
I will destroy them.
I yawn. I am tired of being awake, for now. I shall sleep, and dream of all the little ponies' deaths. Yes, what a pleasant dream that will be. And what a better reality.
