Are you trying to tell me he can manipulate the very fabric of existence himself? [Ok, that's a new one. Total destruction, yeah he knows that. But he's never met anything that can just will something away into nonexistence.]

From the way you make it sound I'm not sure if anyone can help the boy. I'm familiar with turning things to complete dust but not even I have the ability just to make something disappear like a magic act. In fact, not even the gods of my world can do that. What is he?
