Martinet

Martinet is a pit fiend who serves in the court of Asmodeus as his constable. Martinet's job is to clean up the frequent political messes of The Nine Hells of Baator. His influence has stopped several wars from breaking out among the lords, and his diplomacy has ended even more conflicts. Martinet has an extremely level head, and he never flies off the handle. He has withstood the tirades of Baalzebul and Mephistopheles without raising an eyebrow, and he always has a cunning retort. While he is not greatly powerful himself, he is feared because others know he is the voice and mouth of the Dark Lord of Nessus, Asmodeus himself.
There is no doubt that Martinet is the most powerful and influential Duke of Hell, guaranteed by his status as the Constable of Nessus and the Voice of Asmodeus. There is also little doubt that he is the single most despised Courtier of Perdition and that many, particularly the Lords of the Nine, eagerly anticipate the day that his favor before the eyes of The Overlord dims. Fortunately for Martinet, he is well aware of the fine line he walks and he revels in it, knowing full well that Asmodeus is not prone to flippancy or sudden change and that, so long as he stays absolutely loyal to The Overlord - or at least, as loyal an appearance as necessary - he will be able to continue behaving as if he were an equal to the Lords of the Nine .
