Rainbow serpents, named for their glimmering scales, are primordial dragons responsible for shaping the land when the world was young. Since that time, rainbow serpents have retired to the bottoms of lakes and rivers, where they spend most of their time slumbering. When a rainbow serpent awakens, it does so to battle chaos and evil in the vicinity of its watery lair. Preferred targets are individuals responsible for political strife, social upheaval, and the erosion of traditional values.
