What happens when a forest dies? Its treant swears vengeance. Learn about the dark side of treants: fury, hatred, revenge, and the charred, undead creatures left behind when a treant burns! The Complete Guide to Treants is a stand-alone, world-neutral sourcebook covering everything you ever wanted to know about treants. It covers the traditional role of the treant as noble protector of the forest, but also examines the fate of those treants who turn to other means. It includes detailed background material on treants, including their various groves, the guild-like branches of the Vine of Tales, their cosmology, the deep treants of the underdark, and more; stats and background on the dark side of treants – such as shadowed treants, who resort to great evils to protect their trees; full stats for treants as a character race, including four new classes (Firesworn, Treeherd, Woodwarden, and Leafsinger); and, of course, new feats, spells, and other such things. This book uses the 3.0 edition of the d20 rules set, and is fully compatible with the world’s most popular role playing game.
