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.
Mermaids are mythical and legendary sea-dwelling creatures of European & Asian folklore, resembling a woman, with a human torso, but having a fishtail or tails instead of legs. Mermen are also heard of, but have a secondary role in the lore of the sea. Other similar water spirits include nymphs, dryads, oceanids, hamadryads, naiads, nerieds, oreads, and undines. Mermaids are supposed to be able to lure imaginative, amorous men to destruction by enticing them into the depths .
