"Beyond the boundaries of physical space, unrestricted by time or causality, there is a dimension incomprehensible to mortal minds. It lies on the other side of dreams and nightmares, infinite in scope but without form or structure.. The Realm of Chaos exists far outside imagination; an impossible abstraction made real only by metaphor and the roiling emotions of mortal minds. It is constantly reborn but has never changed, eternally shifting though endless in potential. No mundane sense can see, smell or hear it, and even the most powerful Psykers cannot glean the Warp's true nature, lest they be driven insane."
