Mammon

Lord of Greed
The third layer of the Hells is ruled by Mammon the most greedy of the devils. In the depths of Minauros, his motives are some of the most pure in the darkness of the Hells, he is one of the only devils that will trade power for treasure. And many have tried to outsmart him, hoping to use the treasure of dragon hoards, the burial gold of forgotten empires, and gifts of the gods to gain his power.

But many misunderstand Mammon's singular motivation as weakness, thoughts that the dark lord is easy to manipulate are quickly discarded when a bargainer sees the cities of gold that the third layer of Minauros has. If the gold isn't enough to awe travelers, then the dried blood and flesh that cling to the wealth of a million dead sinners will.
