Forsaken

The Forsaken (aka Forsaken Undead, undead Forsaken, or Undead) are a race and faction of undead who broke away from the Scourge and took control of much of the kingdom of Lordaeron, destroyed during the Third War by the death knight Arthas. They are currently allied with the Horde, but in an alliance of convenience only. The Forsaken are led by their Banshee Queen, Sylvanas Windrunner, the former Ranger-General of Quel'Thalas. Their capital is the Undercity, in the royal catacombs beneath the ruins of the City of Lordaeron. Undercity is the faction for the playable Forsaken in-game.
