Potbellied Kobold's Guide to Villains & Lairs: They of Many Colors

From publisher blurb: They of Many Colors is an ancient, feathered dragon; though it more resembles a serpent, lacking wings, legs, and claws. Often, in the taverns of larger cities, one might overhear a story about the giant-sized beast. These city-folk believe it to be a thing of myth and legend. It is not. They of Many Colors considers itself a god, as do many of the people living amongst the forest where the beast lairs. Some pay tribute to They of Many Colors, leaving gifts of food, treasure, and drink on a stone pedestal in the forest near the dragon’s treetop lair. More malicious people lure adventurers to their god’s lair, as their own form of tribute.
