Alrighty, I'm about to get started on that damn profile. But I'd like some opinions on this dudes powers. One idea I had was that he'd be a sort of fallen God-entity given mortal flesh as punishment, who has none of his prior powers save knowledge of the language of the Gods, which can be understood (but not reproduced by) any mortal and used to control them by warping their perceptions. For example, if you wanted to be perceived in a different form, you'd describe said form in the God-tongue and the words would give you a lingering illusionary body. If you wanted to affect a single persons mind dramatically (say by creating such a powerful illusion that they believe they actually are going to die or by haunting them with recurring nightmares) you'd have to know their name or somesuch.

Seem fair?
