Mammon

Mammon is an archdevil who is the lord of the third layer of The Nine Hells, Minauros.

Background
Mammon was an utterly selfish entity that practically personified greed with his insatiable desire. He was a ruthless hunter who would unrelentingly pursue his prey, whether it be an actual quarry or future possessions, but was ambivalent towards his prize once it was actually obtained and would swiftly move on to new targets. While his cupidity wasn't limited to currency, Mammon was wholly materialistic and measured worth in regards to monetary value. He made deals solely for the purpose of making profit and was otherwise indifferent to the results of the exchange. Alongside being avaricious, Mammon was also megalomaniacal, lusting after power and always scheming to acquire more of it.

The methods required to achieve his goals were irrelevant to Mammon and he would perform whatever act he believed necessary to accomplish them. The duplicitous Viscount would seduce his victims with silver-tongued promises before wantonly and gleefully watching their expressions when he betrayed them. The Serpent's speech, like his convoluted schemes, was riddled with winding messages and unclear requests, meandering even when supposed to be delivering orders. Mammon was not only sinister, but shameless, keeping his position primarily by acts of bootlicking sycophantism most charitably described as embarrassing. His pathetic groveling before his master was as renown as his arrogant condescension towards his own inferiors.

Mammon's host of other flaws included his overactive paranoia that drove him in his craven, and often foolish pursuit of loyal servants. This was combined with his petty, oversensitive demeanor and overindulgent hedonism to make a being that was practically impossible to work with. Mammon's typical response to frustration, such as if he felt his time was wasted, was to alleviate the feeling by destroying the offender or otherwise tormenting unrelated parties. No matter how competent the tyrant, it was impossible to stay on Mammon's good side for he had no such thing.
