In
Games Workshop's Warhammer Fantasy and
Warhammer 40,000 fictional universes,
Chaos refers to the malevolent entities which live in a different timespace, known as
the Warp in
Warhammer 40,000 and as the
Realm of Chaos in
Warhammer Fantasy. The term can refer to these warp entities and their influence, the servants and
worshippers of these entities, or even the parallel universe in which these entities are supposed to reside. The most powerful of these warp entities are those known as the
Chaos Gods, also sometimes referred to as the
Dark Gods,
Ruinous Powers, or the
Powers of Chaos. Similarities exist between the Warhammer idea of Chaos and the concept of
Chaos from
Michael Moorcock's
Elric saga, which also influenced
D&D's
alignment system. Further similarities can be seen with the godlike extradimensional
Great Old Ones of horror writer
H. P. Lovecraft's stories.
