Orgrimmar, heart of orcish civilization on Azeroth, was set ablaze by revolution. When Warchief Garrosh Hellscream revived the heart of the Old God Y’shaarj to empower his army, he desecrated Pandaria’s sacred Vale of Eternal Blossoms. This affront, alongside Garrosh’s increasingly dangerous conquests, led Horde rebels and Alliance stalwarts to assail the great walls of Orgrimmar, hoping to dethrone the tyrant before he ravaged an entire world. Alongside Thrall, champions of the Horde and Alliance fought their way to the Warchief’s lair beneath the city, where the battle grew so desperate that Garrosh absorbed the energies of the Old God to halt his downfall. It was not enough. At the behest of King Varian Wrynn, a defeated Garrosh was brought to trial before the August Celestials of Pandaria – but the scars of his rule will bleed for some time.

Garrosh Hellscream's quest for power in Pandaria leads him to excavate part of the sacred Vale of Eternal Blossoms in search of a sinister artifact, a decision that puts the Horde at odds with the Shado-pan and other influential pandaren. Meanwhile, in the Horde capital of Orgrimmar, Chieftain Vol'jin and the Darkspear trolls are declared traitors and hunted by the Kor'kron, Hellscream's personal guard. Vol'jin's people retreat to Durotar and the Barrens to gather supplies and reinforcements for their counter-strike, relying on the support of their former warchief, Thrall, and a particularly tenuous pact with the Alliance, whose interest in ending Garrosh's rule may not bode entirely well for the Horde...

While war between the Horde and the Alliance raged across Pandaria, the scattered mogu plotted a return to their terrible former glory. They rekindled their historical alliance with the Zandalari trolls, who managed to resurrect the tyrannical mogu emperor, Lei Shen the Thunder King, in the hopes of restoring mogu dominion over the continent. The valiant Shado-pan rushed to suppress their enemies, creating a task force, the Shado-pan Assault, originally composed of pandaren warriors and later supported by heroes of the Horde and Alliance. These fearless champions strove to defeat the Thunder King, though they also simultaneously served their factions' interests on Pandaria. Jaina Proudmoore led the Kirin Tor Offensive on a quest to uncover the source of all mogu power (and keep it from the Horde), and Lor'themar Theron took the Sunreaver Onslaught in search of mighty mogu weaponry to aid a daring plan…an insurrection against Warchief Garrosh Hellscream.

The conflict between the Horde and the Alliance entered a bloody new chapter in Pandaria. As the two factions' armies clashed on the shores of the continent, Warchief Garrosh Hellscream dispatched elite troops to find the Divine Bell—an ancient mogu artifact capable of endowing his soldiers with unimaginable power. Garrosh's bold and reckless actions, however, had dire consequences for the Horde, including the outbreak of violence against the Darkspear trolls and the expulsion of the blood elves from the once-neutral mage city of Dalaran. Although Garrosh claimed the bell, Prince Anduin Wrynn and the Alliance secret agents of SI:7 closely tracked the warchief's every move. On the highest peaks of Kun-Lai Summit, the brave prince thwarted Garrosh's plans, leading to the fabled mogu artifact's destruction.
