Anguis (or Lumasi, Vritran, or Primordial Snakes) are creatures of primordial chaos. Anguis descend from one or more emanation of primordial chaos, monsters which rivaled and in many cases predated the gods. Creatures such as Tiamat, Apophis, Jormungandr, Illuyanka, Tannin, Lotan, Zahhak, Yamato-No-Orochi or Echidna, which lost the battle against the forces of Order long ago.
The true form of an Anguis is a giant, primordial monster, generally combining the features of lizard, snakes and/or fish.
As creatures of chaos and corrosion, they can warp and erode both matter and minds. They seek to unmake and destroy reality and their powers reflect this. Primal elemental forces are at their command, representing the primal forces which could destroy early man.
