Fizban's Treasury of Dragons is a comprehensive guide to the dragons of the worlds of D&D. It introduces the gem dragons—a family of five dragon kinds—as well as a variety of other Dragons and dragon-related monsters, character options, and inspirations. It also introduces the myth of the First World, created by the dragon gods Bahamut and Tiamat, giving readers a peek into the role dragons play in the myths of many Material Plane worlds—all with notes and anecdotes from doddering archmage (and avid baker) Fizban the Fabulous, divine avatar of Bahamut himself.
