Warcraft III: Reign of Chaos
After a period of many years of deteriorating in captivity, the remainder of the orcs on Azeroth ended up being freed by the ex- slave known as Thrall. This youthful shaman and the reformed Horde left towards the continent of Kalimdor to flee the attack from the Burning Legion, a demonic military that desired to ravage all Azeroth. To destroy the world's protection, the Legion let loose a terrifying new weapon: the undead Scourge. Royal prince Arthas Menethil of Lordaeron battled fearlessly to guard his lands from this terrifying opposing force, but his fearfulness and paralyzing desparation led him to join forces together with the Scourge's strange leader, the Lich King. On Kalimdor, Thrall's Horde put aside older hatreds and combined along with other races to combat the immense Legion assault helmed by the demon lord Archimonde. At great expense, the improbable partnership of humans, night elves and orcs overcame their adversaries on top of sacred Mount Hyjal.
