The Immaterium is a psychic parallel to 'Real space', where, within this realm, there are no physical laws as such; they are more akin to guidelines, that subjects can use or bend, unlike those that dominate the mortal plane. Few mortals are capable of perceiving this dimension in its true splendour, for the living mind recoils from such outlandish domains. This realm is a place of dreams, and nightmares; within its bounds, anything is possible.
