I am neither all-knowing nor all-seeing, which can go hand-in-hand with all-powerful. My magic is very powerful, but there are things I cannot do. I can reanimate someone, bring them back from the dead, but I cannot fully resurrect them. They won't be completely the way they were before they died, and they will be stuck in a decaying body because I cannot restore a body completely to life. I can shapeshift, but I can only take the form of an eagle.
