SHUMBRA, The Caliginous Warlock, is the Elemental Deity of Darkness. He's usually depicted as a humanoid adorned in ceremonial black feathers, with a blind head, a snout full of fangs, twisted into a malicious snarl. He is thoroughly evil, and deceitful; he is the shadow that lurks in the night. He thrives on fear and misery.
He tends to be worshipped by tricksters, thieves, and sadistic or selfish people, as he helps out people who do things for their own benefit without considering anyone else.
