Arc 21The Dark Portal War
Thrall’s coalition defeated Garrosh and the Heart of Y'Shaarj, but Garrosh escaped to another Draenor and united the True Horde. When the True Horde invaded Azeroth, the allied forces crossed the Dark Portal in turn and divided across Draenor as new conflicts gathered.
- Zul'jin and Nalorakk broke through Razor Hill’s weakened wall, while Jaina and Varian rallied more forces to the resistance and the Night Empire joined the campaign.
- Saurfang and the Alliance captured Orgrimmar’s harbor, then the resistance, Goblin rebels, and Night Empire attacks broke the city’s defenses and surrounded Garrosh’s remaining troops.
- Thrall defeated Nazgrim, who was healed by a ray of dawn, and the rebels fought their way toward Garrosh as Cthulhu’s power disrupted the battle and N'Zoth fled Twilight Citadel.
- Thrall negotiated with Gazlowe, then confronted Garrosh, who fused with the Heart of Y'Shaarj before Grandmother Gaia'an’s words led him to release it and collapse.
- The Horde chose Vol'jin as Warchief and sent Garrosh to Pandaria for trial, but Kairozdormu helped him escape to a parallel Draenor, and Thrall later admitted he had enabled the escape.
- Garrosh killed Kairozdormu, joined Grom Hellscream, and helped the True Horde resist Gul'dan and defeat Brutallus as the Orcs built a Dark Portal to Azeroth.
- Grom led the True Horde through the completed portal, where Azeroth’s armies repelled the vanguard, and the Allied Forces counterattacked through the portal and advanced into Draenor.
- The Allied Forces divided across Draenor as Velen’s Draenei joined the Alliance in Shadowmoon Valley, while Crusaders secretly freed Gul'dan and the Shadow Council warlocks.
