The third Dungeons and Dragons book for 2021 has been announced; it will be called Fizban's Treasury of Dragons. Oddly enough, it will focus heavily on dragons, which happens to be a major part of the game (the clue is in the name, after all).
Fifth Edition D&D books that aren't adventures tend to feature a prominent character from the game's canon. Fizban is a rather doddery arch-mage who may or may not be the all-powerful dragon god Paladine in disguise.
The book is intended to be used in all D&D setttings, though the book's title is a nod to the Dragonlance setting. It will be crammed with references to D&D's rich history of dragon-inspired storytelling. We understand that Dragonlance's iconic Draconians will feature in this book, with rules that will allow you play them in different settings.
The book will feature extra rule, character options and story ideas. This includes introducing a third faction of dragons, the crystalling dragons. The book will go into the story of the First World and the role Bahamut and Tiamat played in its creation and destruction.
New character options will include draconic-themed subclasses for monks and rangers, as well as new spells and feats. New types of Dragonborn will also be in the book, as well as dragon lair maps and many different kinds of dragons.
The book comes out October 19th, 2021, and will be available in normal and special 'art' cover hardback variants.
