Story recap page for the fifth World of Warcraft expansion pack, Warlords of Draenor.
Before he can be judged for his war crimes in Pandaria and Kalimdor, Garrosh escapes captivity with the aid of a renegade bronze dragon, Kairozdormu, who allows for Garrosh to time-travel back to the once orcish homeworld of Draenor and interferes with history; creating an alternate timeline prior to the rise of the Horde. Garrosh changes history by preventing his father, Grommash Hellscream, from drinking the blood of the Pit Lord, Mannoroth, which led to the orc's corruption by the Burning Legion, and played a major role in the events of the first three Warcraft RTS games. Instead, the clans unite into an "Iron Horde" using technology Garrosh brought from his reality; beginning a war of conquest on Draenor by killing Mannoroth, and leading to the construction of a time-traveling Dark Portal that would allow for them to travel through time to lay siege to the Azeroth of the present era.
Garrosh's Iron Horde storms through the Dark Portal only to be met by heroes that were called upon by King Wrynn and Warchief Vol'jin. However, a small band of Iron Horde forces led by Warlord Zaela manage to break through the Azeroth armies, and are able to find refuge in what used to be Rend's fortress for the Dark Horde of Blackrock Mountain. Heroes of the Horde and Alliance are then tasked to return to the Upper Fortress of the spire to dispose of Zaela's group. Soon after, with the help of Khadgar, the forces of Azeroth are able to fight the Iron Horde Vanguard back through the portal to the alternate Draenor.
The Azeroth Vanguard pursue their attackers through the Dark Portal to the alternate-Draenor, and use the Iron Horde's own weaponry to destroy the portal entrance on Draenor's side, but were subsequently forced to flee in order to evade the full might of the Iron Horde. The Azeroth Vanguard fled to the docks, and split into two ships with the Alliance following the Draenei, and the Horde joining the Frostwolf Clan. Afterwards, the Alliance and Horde established bases with portals to Azeroth to bring in supplies. The Alliance and Horde continue to fight back against the Iron Horde, and ultimately confront the escaped war criminal, Garrosh Hellscream, in Nagrand. Garrosh counters the efforts of the heroes, but were saved by the intervention of Thrall who challenges Garrosh to mak'gora - a duel of honor that can led to death. In the battle that followed, Garrosh initially has the upper hand, and blames Thrall for Garrosh's own failures, but Thrall counters by stating that what Garrosh had done were choices that he made on his own. Utilizing his elemental powers, Thrall finally kills Garrosh off for good.
