The devastating Second War against the orcish horde left the Alliance of Lordaeron in a state of shock and disarray. The bloodthirsty orcs, led by the mighty warchief, Orgrim Doomhammer, not only smashed their way through the dwarf-held lands of Khaz Modan, but had razed many of Lordaeron's central provinces as well. The unrelenting orcs even succeeded in ravaging the
elves' remote kingdom of Quel'Thalas before their rampage was finally stopped.

The Alliance armies led by Sir Anduin Lothar, Uther the Lightbringer, and Admiral Daelin Proudmoore pushed the orcs south into the shattered land of Azeroth - the first kingdom to fall before the orcs' ruthless onslaught.

The Alliance forces under Sir Lothar managed to push Doomhammer's clans out of Lordaeron and back into the orc-controlled lands of Azeroth. Lothar's forces surrounded the orcs' volcanic citadel of Blackrock Spire and laid siege to their defenses.

In a last-ditch effort, Doomhammer and his lieutenants staged a daring charge from the Spire and clashed with Lothar's paladins in the center of the Burning Steppes. Doomhammer and Lothar squared off in a titanic battle that left both mighty combatants battered and drained. Though Doomhammer narrowly succeeded in vanquishing Lothar, the great hero's death did not have the effect the warchief had hoped for.

Turalyon, Lothar's most trusted lieutenant, took up Lothar's bloodstained shield and rallied his grief-stricken brethren for a vicious counterattack. Under the ragged standards of both Lordaeron and Azeroth, Turalyon's troops slaughtered the bulk of Doomhammer's remaining forces in a glorious, but terrible rout.

There was nothing left for the ragged, scattered orc survivors but to flee to the last standing bastion of orcish power - the dark portal.

Turalyon and his warriors chased the remaining orcs through the festering Swamp of Sorrows and into the corrupted Blasted Lands where the dark portal stood. There, at the foot of the colossal portal, the broken horde and the rugged Alliance clashed in what would be the last, bloodiest battle of the Second War.

Outnumbered and driven mad by the curse of their bloodlust, the orcs inevitably fell before the wrath of the Alliance. Doomhammer was taken prisoner and escorted to Lordaeron while his broken clans were rounded up and hauled north - back to Lordaeron.
