The sourcebook gives details of each dragon's powers, tactics, myths, lairs, servitors, and more. In addition, this book provides new information about draconic nations (such as Arkhosia) and organizations, and how chromatic dragons fit into the D&D game. Wide-ranging story and campaign elements in the book give DMs ready-to-play material that is easily incorporated into a gane, including adventure hooks, quests, and pregenerated treasure hoards.

Draconomicon I: Chromatic Dragons describes several varieties of dragons, including red, blue, green, black, and white dragons, as well as three completely new chromatic dragons: the brown, the purple, and the gray dragons!
