It varies. If I want something to happen, I can will it into happening. I can step outside the universe -- sometimes -- and rearrange things so they happen like I want them to. I can build universes and dimensions and just ... anything, really.
Um, also I know all the spells from Harry Potter and can do all of them with varied success -- except the bad ones -- obviously. But I don't know if I make them work properly or just will them to work.
