Daemons or "Warp Demons" are entities of the Warp, and servants of Daedalus. They were not part of The Invasion Not to be mistaken for Demons from the Nether. Daemons are created at the whim of a Chaos god from a fraction of the god's own power and act as an extension of their will.Being an entity of the Warp (a dimension of the immaterial) a daemon cannot exist for long periods of time in realspace, any more than a mortal can survive unprotected in warp space. There are a few ways a daemon can breach the walls separating warp from real space and gain entry into the mortal universe. Daemons can be fought in a physical sense whilst in realspace but are rarely killed, more frequently they are banished back into the warp to fester and brood until their next chance into realspace presents itself.
In order to enter real space in greater numbers Daemons need to use Warp rifts. These are breaches in the fabric of reality that can vary in nature and size. At times a Daemon can possess a mortal and turn him into a portal through which whole hosts can pass. These daemonic incursions can taint real space severely, often twisting and reshaping whole planets until they are lost and turned into Daemon Worlds.It is not surprising that the Eurasia's Witch Hunters are granted unlimited resources to deal with such threats.
Greater Daemons are the most powerful of the Chaos Gods servants. They act as wardens of their patron's realm and have authority over the lesser Daemons of their respective God. It is often they who lead Daemonic Incursions.
The followers of Chaos try to gain the attention of their gods in order to gain terrible power and great rewards.
They are the foot soldiers of Chaos, building the core of the Daemonic Legions. They are usually anthropomorphic in appearance and possess a calculating, malevolent intellect.
