Thrall, born as Go'el, is a fictional character who appears in the Warcraft series of video games by Blizzard Entertainment. Within the series, Thrall is an orc shaman who served for a time as a Warchief of the Horde, one of the major factions of the Warcraft universe, as well as the leader of a shaman faction dedicated to preserving the balance between elemental forces in the world of Azeroth known as the Earthen Ring. Originally introduced in promotional material released by Blizzard Entertainment as the protagonist of the canceled video game Warcraft Adventures: Lord of the Clans, which was co-developed by Blizzard and Animation Magic from 1996 until 1998, Thrall's first proper appearance is in the 2001 novelization of the canceled video game's narrative authored by American novelist Christie Golden. The novel's story is set during his youth, where he is depicted as a slave who was raised by an abusive human military officer, but eventually rebelled and escaped captivity.

Warcraft Adventures: Lord of the Clans is a cancelled graphic adventure game developed by Blizzard Entertainment and Animation Magic from 1996 until 1998. Set in the Warcraft universe after the events of Warcraft II: Beyond the Dark Portal, it followed the orc character Thrall in his quest to reunite his race, then living on reservations and in slavery following its defeat by the human Alliance. Assuming the role of Thrall, the player would have used a point-and-click interface to explore the world, solve puzzles and interact with characters from the wider Warcraft series.
