Background
Malikon is one of the more subtle of demon princes, and is less dedicated to chaos and destruction than his brethren. He seeks to gain domination through subterfuge rather than direct force. His main center of power is the Council, a group of conspirators located in the Bandit Kingdoms (near Rift Canyon). From their hidden stronghold, they seek to influence events on the Flanaess. It is known that their agents have penetrated (and possibly control) the network of the slave lords, the orcish empire of the Pomarj, and the Scarlet Brotherhood. They also have many allies in humanoid regions throughout the Flanaess, and in the subterranean cities of the Drow. His priests are always seeking to turn new nations to Malikon's cause. They are currently concentrating on infiltrating the United Kingdom of Ahlissa (seeking to gain back power lost in the fall of the Malachite Throne).

Malikon's priests rule over an elite order of knighthood, known as the Dark Legion. These knights have priestly powers similar to those of a paladin, as well as fearsome skill in combat. Fortunately, there are less than 50 full knights in the Legion at this time, though Malikon's priests are always eager to enlist new warriors in their service.

Malikon is known to have great enmity with the Demoness Lolth, as well as with Fraz'Urb'Luu (Prince of Deception). He is currently allied with Graz'zt and Yeenoghu. He normally appears as a shadowy figure in rune-covered black plate armor, wearing a great cloak of mingled fire and shadow. It is unknown if this is his true form.

Malikon (and his background) are largely my own creation, though he is loosely based on Tyranthaxus, the Forgotten Realm's Lord of Tyranny
