In worlds that Chaos conquers the Phase energy becomes corrupted. This corrupted energy will often become these things, commonly called Chaos creatures or Corrupts. When these creatures are 'killed' their energy cycles through the Phase again and becomes uncorrupted. In order to reclaim a world from Chaos all of the creatures must be destroyed.
