Immaterium

The Immaterium, also referred to as the Empyrean, the Aether, the Sea of Souls, the Realm of Chaos, Warpspace or most commonly, “the Warp,” is an alternate dimension of purely psychic energy that echoes and underlies the familiar four dimensions of the material universe. The Warp is the source of all psychic powers and known instances of so-called “sorcery” or “magic” as well as the home dimension of the powerful entities known as the Chaos Gods and their myriad legions of Daemonic servants. In fact, the terms “Chaos” and the “Warp” are often used interchangeably by those aware of their existence within the Imperium of Man. Superficially, the Immaterium is Mankind’s solution to the problem of faster-than-light travel. The Warp functions as the medium for FTL interstellar travel, with voidcraft entering it through the use of a Warp-Drive.
