Eir

Eir is the god of madness, darkness, cruelty, mockery, and corruption. Its divine pair is Serenae. It is associated with hags, gremlins, insanity, and dark magics. It is the most eager to corrupt whenever it has the opportunity, and none depraved enough to worship it are spared from its twisting influence. It creates mockeries of humanoids, personifying their deepest regrets, darkest impulses, and greatest fears.
