A prominent character in Blizzard Entertainment's Warcraft universe, Thrall initially became a primary character in the Warcraft storyline through his role as warchief of the orcs in Warcraft III: Reign of Chaos, a role which Blizzard continues to expand upon in World of Warcraft.
Born of an orc tribe that stoically believed in the ancient shamanistic roots of the orc people, the infant Thrall was found among the bodies of his recently murdered parents by the commander of the Human-run orc internment camps, Aedelas Blackmoore. Intending to turn Thrall into a gladiator of unparalleled skill, Blackmoore saw to it that Thrall was trained, wet-nursed, and educated by humans. Despite this nurturing, Blackmoore treated Thrall with scorn and disdain, and constant beatings and mistreatment eventually led Thrall to escape his captivity and regain his original place among the exiled orc clan of the Frostwolves. Soon afterward, Thrall became the first new shaman of the orcs since their corruption by the warlock Gul'dan. Thrall went on to lead an uprising of his people which resulted in the destruction of the internment camps, and he eventually became warchief of the combined clan armies.
