Asmodeus (Dungeons & Dragons)
In the Dungeons & Dragons roleplaying game, Asmodeus (/æzmɵˈdeɪəs/az-mo-DAY-əs or /æzˈmoʊdiəs/az-MOH-dee-əs) is an Arch-Devil: a lord of the game's version of Hell (Baator in 2nd Edition; also in early 3rd edition but increasingly referred to as "the Nine Hells" in 3.5 products). There he is the Overlord of the Dukes of Hell. His symbols include a clawed fist gripping a skull and a ruby-tipped rod.
In the game's in-universe history, Asmodeus retained his position all through the Reckoning of Hell, unlike many of the other arch-devils. Asmodeus is specifically the lord of Nessus, the Ninth Layer of Hell, but he reigns as king over all of Baator.
