The Battle of Grim Batol (History of Warcraft)
- Deepwater Tavern in Wetlands.
- Hall of Explorers in Ironforge.
- War Room of Stormwind Keep in Stormwind City.
- Bael'dun Digsite in Mulgore.
Meanwhile, in the war-torn lands of the south, the scattered remnants of the Horde fought for their very survival. Though Grom Hellscream and his Warsong clan managed to evade capture, Deadeye and his Bleeding Hollow clan were rounded up and placed in the internment camps in Lordaeron. Notwithstanding these costly uprisings, the camps' wardens soon re-established control over their brutish charges.
However, unknown to the Alliance, a large force of orcs still roamed free in the northern wastes of Khaz Modan. The Dragonmaw clan, led by the infamous warlock Nekros, was using an ancient artifact known as the Demon Soul to control the Dragonqueen, Alexstrasza, and her dragonflight. With the Dragonqueen as his hostage, Nekros built up a secret army within the abandoned - some say cursed - Wildhammer stronghold of Grim Batol. Planning to unleash his forces and the mighty red dragons on the Alliance, Nekros hoped to reunite the Horde and continue its conquest of Azeroth. His vision did not come to pass: a small group of resistance fighters, led by the human mage Rhonin managed to destroy the Demon Soul and free the Dragonqueen from Nekros' command.
In their fury, Alexstrasza's dragons tore Grim Batol apart and incinerated the greater bulk of the Dragonmaw clan. Nekros' grand schemes of reunification came crashing down as the Alliance troops rounded up the remaining orc survivors and threw them into the waiting internment camps. The Dragonmaw clan's defeat signaled the end of the Horde, and the end of the orcs' furious bloodlust.
