The infinity castle. A familiar sight, one of the only one's you have ever known. You haven't seen much of the world, not knowing where to go, and not knowing if anyone would come for you if you didn't come back.
Your father wouldn't, that was sure. No, he wouldn't come for you, he might never even notice your absence at all. And if he did come looking, how would he know who to look for? He never looks at you. Does he even know what you look like at all?
This is just another day in your dull, lonely life. The upper moons are to scary to be around, every demon is, and your father, as always, wouldn't pay attention to you. Busy with experimenting, trying to find a way to immortality. You can see him from here, standing busily over the table, his expression one of concentration.
Sometimes you wonder if he ever found one, if he would just discard you. He would have no more use for you, then, right?
