Oghma, the Incomprehensible

Oghma, the Incomprehensible is a deity of the Knowledge Domain, the Arcana Domain, and the Trickery Domain. Oghma resides in The Plane of Chaos where no other deity would trespass and has large cults in the Material Plane who enter into deals with Oghma that are skewed in his favour and usually end up driving the worshippers who lust after the knowledge mad.
