Phenax

Phenax is the god of cheats, liars, and tricksters. He governs magic, gambling, deception, betrayal, isolation, planning, and secrets. He is worshipped by criminals and others who wish to subvert the rules and gain an advantage through deception. Despite this, he is not a malevolent god, as he views pure malevolence to be rather straightforward and uninspired. Temples to Phenax are typically hidden in plain sight, but marked clearly for those who know what to look for.
