Well, up until now, all magic has been illusions and mental powers. The power to influence the minds of others. As such, how about Stigma?

Stigmata? Like cause black spots to appear on someone's palms? Not really very interesting.
Note that I don't care about power, It needs to be otherworldly though.
As long as it is powered by a complete disregard of common sense.
I'll stick to influencing minds for now then.

EDIT- Oooh I got just the thing!
