Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Races of the Dragon is an optional supplemental source book for the Dungeons & Dragons fantasy role-playing game. This book contains info on two new races. One criticism that this book has received is that it offers an overpowered new race that is theoretically the best one for Dungeons & Dragons sorcerers, a class that uses magical power derived from having dragon blood. Dungeons & Dragons (abbreviated as D&D or DnD) is a fantasy role-playing game (RPG) originally designed by Gary Gygax and Dave Arneson, and first published in 1974 by Tactical Studies Rules, Inc. (TSR). The game has been published by Wizards of the Coast since 1997. It was derived from miniature wargames with a variation of the Chainmail game serving as the initial rule system. D&Ds publication is widely regarded as the beginning of modern role-playing games and the role-playing game industry.
