Something went wrong. You try to remember what exactly occurred... you remember warping to the edge of the universe, holding onto... something. You don't remember what it was, but it was frightening, and now everything is black. You think for a moment, accounting for the tug at your feet.
You panic, engulfing your body within your own soul. That should give you some time to think.
You are inside of the event horizon of a black hole.
Even if you were to escape, it would be meaningless due to the massive amount of time dilation you have already undergone. Chances are, everyone you have loved and cared about is already gone. The only chance you would have at getting back is if you stumbled upon Niki, but the planet has likely been engulfed by the sun already.
You begin to think to yourself, but realize even if it is impossible, its your best shot anyway.
