The Warforged are a race of living constructs originally created by the Gnossians in the old empire. Gnomish arcanologists rediscovered the Warforged creation core and reactivated the technology. The Gnomes accepted the sentient constructs into their society as a labor class, where they serve as soldiers construction workers and in other positions that take advantage of their physical prowess.
Though they have free will, whether they have a soul is not known with certainty; they can be resurrected by spells designed to restore human souls to life, but, unlike humans, never remember anything of their experience in the afterlife after such an event.
While they have no biological sex, warforged may adopt a gender role as part of their individual personality. They do not age as the other races do, and it is not known what effects time will have on them. It is generally assumed that, like all living creatures, their bodies must experience degradation over time. Like other races, warforged may take levels in any character class.
