In the Dungeons & Dragons fantasy role-playing game, Deathless was a classification of monsters that could be encountered by player characters. Deathless are creatures that have prolonged their lives unnaturally using magic.
Description
Deathless are defined by their opposition and contrast to Undead, in that Undead are associated with negative energy, death and decay, while Deathless are associated with life-based magic.
Deathless as a creature type first appeared in the Book of Exalted Deeds, published by Wizards of the Coast, in 2003. It subsequently appeared in a smattering of Third Edition publications, including the Eberron Campaign Setting.
Deathless as a creature type has not appeared in the Fourth Edition of Dungeons & Dragons. Fourth Edition D&D defines creature types differently from earlier editions, so creatures that appeared as Deathless in Third Edition may be defined in terms of other creature types.
