Daemon World - Daemon World: A Daemon World is a planet twisted and corrupted by the power of Chaos and the Warp after being trapped in a prolonged Warp rift. Entwining the impossibilities of the Warp and the reality of the material universe, Daemon Worlds are not bound by the laws of physics, but by the whim of their Daemonic rulers and the emotions of their mortal inhabitants' collective unconsciousness.Daemon Worlds are usually ruled by a Daemon Prince, who can shape the world's environment and nature to their liking due to the pure psychic mutability of the Warp. Each of these worlds is a bizarre sub-reality ruled by their terrible Daemon Princes. The majority of the known Daemon Worlds are to be found within the great Warp rift known as the Eye of Terror.Those few that are known to exist within realspace within the boundaries of the Imperium of Man are rigorously quarantined by the forces of the Imperial Inquisition. These worlds are rarely subject to an Exterminatus, as the reality-shifting effects which predominate in the local space around a Daemon World usually preclude any attempt by the Imperium to eliminate it. This is one reason why the Inquisition will move so swiftly and mercilessly to unleash a purge upon any world where the forces of Chaos gain a hold, to preclude them from transforming it into another Daemon World that will be impossible to eradicate from Imperial space.The four major Chaos Gods continuously compete to possess the Daemon Worlds. Armies of Daemons and their mortal allies fight huge and bloody battles to determine which of the Ruinous Powers will dominate them, adding the world to their realms within the Warp. These battles often last for hundreds of standard years, so that the entire world becomes little more than a gigantic arena where the opposing forces are pitched against each other. The Ruinous Powers do not, of course, appear in person to lead their armies -- they are spectators to events, not participants. Their generals are Greater Daemons and favoured Daemon Princes who, because they were once alive as mortals, understand the nature of both the material universe and the Immaterium.The most powerful of Human psykers have reportedly had visions of worlds located in the Eye of Terror. On one world a black sun stands in a white sky and smoky threads pour from it onto a tangled black city. This is Medrengard, the world of the Daemon Primarch Perturabo of the Iron Warriors Traitor Legion. Another planet within the Eye is marked by lakes of blood from which spheres of fire float into the air and spread their light across the sky. This is Bubonicus, the world of the Daemon Prince of the same name, a servant of Nurgle. Visions of such places routinely disturb potent psykers across the galaxy, and can presage an attempt at Daemonic possession.Once a Daemon Prince has conquered a Daemon World or brought a world from the physical universe into the Warp, their grateful divine patron gives it to them as a gift to rule over as they wish. When a Daemon Prince takes control of their hard-won world they use their mighty sorcerous powers to reshape it into a new form which pleases them. Because of this, every Daemon World is different and all are equally horrific in their own way.
