Ranald
The human god of tricksters in Warhammer Fantasy. Not an evil god, he's more the patron of Bards and internet trolls. He's not the kind of god you devote yourself to at a shrine, more the kind who's name you say over and over from either a poker table or from the bottom of a foxhole.
According to myth, he stole divinity from Shallya. This has not earned him any endearment from most of the pantheons of the world.
