Undead get the prestige treatment in Libris Mortis, the second of Wizards of the Coast's highly-focused, hard-cover and color-illustrated monster source books.
Like the Draconomicon before it, Libris Mortis starts off with an overview of undead, delving into physiology, psychology, society, and religion. Although brief, it hits on the major points of the undead life cycle, including their creation and connection to the Negative Energy Plane, rules for "hauntings" (locations infused with negative energy, but not proper undead) and new rules for undead cravings. The cravings -- a ghoul's hunger, a vampire's thirst -- are addressed both as part of the undead's unnatural ecology, and as a motivating force for them. It also gives a brief rundown of the various undead deities, including the major powers from the traditional Greyhawk pantheon (Nerull, Wes Jas, etc.) as well as a few new lesser and demigod additions.
