Tiamat

TIAMAT IS THE EVIL GOD OF WEALTH, greed, and envy. She urges her followers to take vengeance for every slight, and she is the patron of chromatic dragons and those whose lust for wealth overrides any other goal or concern. Tiamat has five heads, each the shape and hue of that of a different chromatic dragon. Perhaps five minds drove her to madness, because Tiamat is bitter and wicked. Her story is a topic of art, myth, and legend throughout the cosmos.

A nightmarish synthesis of hatred, rage and draconic might is embodied in the huge form of a five-headed dragon. The dragons sinuous body is powerful and thickly scaled, the color of dark wine or
dried blood. Her long tail ends in a scorpions venomous barb.
