Rhul Tháar, The Garden of Filth

Name: Karuz Thrak
Type: Demon Lord of Pestilence, Diseases and Plagues
Appearance:
An imposing figure, over seven feet in height, his face ever shrouded in a hood, and radiating the faintest light green aura, Thrak is capable of striking fear into even some of the most stalwart of champions.
Personality and Drive: Relatively silent, and very soft spoken, as if he were the whisper of a silent death, Karuz Thrak works towards the ultimate goal of imbuing all mortals with the “gifts” of his realm. To spread disease and pestilence to all, so that all become equal under its grasp. Karuz sees the existence of pestilence and disease as proof that mortality is not supposed to be. Life is suffocated under the grip of an epidemic, and life itself cannot fight back without the medicines and magics that it uses to defend itself.
He regards other Demon Lord and Champions of the Planes as outside the realm of his influence, as he has yet to successfully be able to infect a fellow demon with the even the dullest of ailments.
Karuz Thrak does not see his intent as malicious, the pain inflicted by the tools of his trade is merely a side effect of the greater goal, to guide the mortal soul to its inevitable fate.
History: Humanity has, in the past, come dangerously close to extinction at the hands of epidemics or other plagues. Usually it is by some miraculous medicine or shielding magic that they are saved from the void. Thus, his eternal life has been endlessly disappointing to Karuz Thrak.
As his human cultists would tell you, Karuz Thrak was born of the first plague of man. Created by the Gods to reign in the world of mortals with pestilence and disease as his tools. Since the dawn of man, Karuz Thrak has waged his battle against life and its tireless perseverance. In recent years he has remained rather inactive, a depression has fallen over the Demon Lord if you will. His holdings crumble around him, and as his efforts seem tireless he has begun to have a sort of existential crisis (as much of one as a Demon can have). He still pierces the world of mortals every now and then, throwing at humanity the all manners of flu and pox, and perhaps more is coming.
Armaments: The only weapon carried by Karuz Thrak is the short sword at his side. Its blade containing a trace of every plague there has ever been or ever will be. It is merely for the purpose of defending against other Demon Lords who might wish him harm, and for instances where he finds it necessary to strike down specific individuals in the most painful of ways.
Abilities: From his hands come decay and rot, anything living that his body touches immediately decays. Aside from this is his demonic strength and fortitude, it would take much to fell the Plague Lord.

Name:Toruz Mak

Type: A ruined city within one of the immense caverns of Rhul Tháar, ever crumbling and smelling of the rotted bodies that populate its cracked architecture. Bloated growths appear throughout the city streets, spores float throughout the air, and the denizens of The Decay wander the streets. The city resembles the ancient great cities of mankind, though it is hard to see this past the spore releasing growths and collapsed buildings.

The Cult of The Plague's history is long and cloudy. It is not clear when the first cultists began practicing their devotion to Karuz Thrak and endeavoring serve him. What is clear is that they most often operate alone, and very rarely interact in large groups. These agents of the decay spread disease and pestilence among the worlds of men in secret. Many plagues that have afflicted mankind have been given a helping hand, much to the credit of these disturbing men and women.
