Mammon

Mammon is a devil, ruler of the third of the Nine Hells, progenitor of Nothing's bloodline and her oncetime patron.

Appearance
Mammon has yet to be seen in person, and the only potential indicator of his physical appearance is the design of the demon hunters' crest. He may have red eyes, as on the occasions that he has spoken through the mouths of others their eyes have turned a fiery, glowing crimson. The tieflings of his bloodline have red skin and curled horns - whether this represents their progenitor's own appearance is unknown.

His voice is low, dark, and rumbling.
