Mammon

Waren of the Gaunt Halls of Avarice, Lady of Plenty

Mammon, the Sixth Lord of Hell, is perhaps the most deceptive and insidious Lord in all The Nine Hells. She appears as an an attractive, gold-skinned tiefling woman who dresses in lavish celestial style. Her angelic appearance is completely seamless, even in her alternative form as a large golden dragon. Her Gaunt Halls are a large, rich estate overflowing with music, water, food, and glamor in sharp contrast with the barren wasteland outside its gates. Her unfortunate wards live in paralyzing fear of being thrown out on a whim, and are forced to grovel for her favor and hand-me-downs in sharp contrast with their rampant excess and greed in life. For this reason, she is unintentionally one of the most efficient Wardens in Hell, as souls repent and diminish to the Shadowfell in her shadow.
The Lady of Plenty is a domineering, entitled, and elegant archdevil whose sole aim is to own everything in the world. She has many warlocks contracted with her, and a prominent cult on the Material Plane because of her willingness to cut deals with mortals in exchange for their souls. Many of her followers are placed strategically in high-ranking positions across Talonn to better obtain whatever Mammon's heart's desire is: artifacts, knowledge, power, money, or even people's loyalties or memories. Her abyssal vacuousness within makes her insatiable, and dangerous.
Among the archdevils, she is widely hated by most, with the exceptions of: Baalzebul, her on-and-off lover; Argus the Vigilant, who she has a bizarrely friendly battle of manipulation going with, and secretly hates; and Tempus, who she pursues unsuccessfully as he considers her simple and easy to manipulate. Because of her lack of romantic success with Tempus, she resents and hates Sune, who she styles herself after.
