Fraz-Urb'luu

"This hulking menace stands just over 18 feet tall, despite his hunched posture. His muscular body is covered with short, coarse pale-blue fur. Two black, leathery wings protrude from his back, and his coiling tail ends in a cruel razor-sharp point. His face is framed by large, ragged ears, and while his eyes are relatively small, his mouth is overly large and filled with fangs."

Deceptive Fraz-Urb'luu is the patron demon lord of illusionists and tricksters, a wrathful prince who only recently escaped imprisonment on the Material Plane.

Combat
Fraz-Urb'luu begins combat by summoning monsters and demons, sending these minons to engage the enemy while he hangs back using support spells to aid them. His hatred for humanity tends to trump these tactics, however. Against humans, he prefers to close to melee immediately, focusing his physical attacks on such enemies until they are slain. He is a master of summoning, and the creatures he conjures are more powerful than normal. His most potent ability is to deceive other demon lords into believing they have been summoned. He uses this ability to cover his escape or to trick other powerful demon into fighting his fights.

His vision is excellent and piercing with both darkvision and true seeing. His ability to fly is average. His challenge rating is a 21.

In ancient Narfell
In -181 DR the ruler of Narfell, Ilithkar, was overthrown by his cousin Rheligaun "the Horned," a half-fiendish son of Fraz-Urb'luu.

Recent history
Since his recent escape from the Material Plane, Fraz-Urb’luu has spent the past 25 years rebuilding his Abyssal realm of Hollow’s Heart and searching for his staff, a potent artifact that was stolen at the time of his imprisonment. Fueling these goals is rage—rage focused primarily on all of humanity. Fraz-Urb’luu hopes that when he has fully reestablished his power over Hollow’s Heart and has reclaimed his staff, he’ll be able to bring this rage to bear on his enemies.

Fraz-Urb’luu counts no other demon lord as an ally, because his ability to deceive them and trick them makes him particularly hated among his kind. Rumors hold that this hatred might have encouraged some of the other demon princes to aid in Fraz-Urb’luu’s imprisonment. For now, his enemies keep a watchful eye on Hollow’s Heart but dare not move against him. He might be alone, but Fraz-Urb’luu remains one of the more powerful of the Abyssal lords nevertheless.

Minions
Fraz-Urb’luu prefers minions that play to his strengths of deception, seduction, and treachery. Succubi are one of his favorite tools, as are the sinister lilitu. He also commands a large number of chaotic evil rakshasas known as the Hollow Rajahs.

Cult of Fraz-Urb'luu
Fraz-Urb’luu’s cults are known as the Cults of Deception. A typical cult consists of a dozen or so members, most of which have at least a few levels of cleric. Posing as benign sects of obscure deities, these cultists seduce and trick people into joining their ranks and offering their misguided worship to Fraz-Urb’luu. These poor folk are doomed the moment they join a cult, for eventually they are sacrificed or goaded into sacrificing themselves. These poor deluded souls inevitably find themselves the eternal prisoners of Fraz-Urb’luu in his mighty city of Zoragmelok on Hollow’s Heart.

Clerics of Fraz-Urb’luu have access to the domains of Chaos, Demonic, Evil, and Trickery. His symbol is his staff—a jeweled scepter of adamantine cast at the end to resemble five bestial arms that splay outward to grip a horned and fanged humanoid skull.

Fraz-Urb'luu in other worlds
On the world of Oerth, the most significant event in Fraz-Urb'luu's recent past was his imprisonment below Castle Greyhawk by the mad archmage Zagig. He remained imprisoned in those infamous dungeons, trapped in a bas-relief carving on a wall, for over two hundred years before he was accidentially released by a pair of adventurers whom Fraz-Urb'luu promptly repaid by destroying their gear and stranding them in his Abyssal realm.
