Old Hatreds - The Colonization of Kalimdor

Though victory was theirs, the mortal races found themselves in a world shattered by war. The Scourge and the Burning Legion had all but destroyed the civilizations of Lordaeron, and had almost finished the job in Kalimdor. There were forests to heal, grudges to bury, and homelands to settle. The war had wounded each race deeply, but they had selflessly banded together to attempt a new beginning, starting with the uneasy truce between the Alliance and Horde.

Thrall led the orcs to the continent of Kalimdor, where they founded a new homeland with the help of their tauren brethren. Naming their new land Durotar after Thrall's murdered father, the orcs settled down to rebuild their once-glorious society. Now that the demon curse was ended, the Horde changed from a warlike juggernaut into more of a loose coalition, dedicated to survival and prosperity rather than conquest. Aided by the noble tauren and the cunning trolls of the Darkspear tribe, Thrall and his orcs looked forward to a new era of peace in their own land.

The remaining Alliance forces under Jaina Proudmoore settled in southern Kalimdor. Off the eastern coast of Dustwallow Marsh, they built the rugged port city of Theramore. There, the humans and their dwarven allies worked to survive in a land that would always be hostile to them. Though the defenders of Durotar and Theramore kept the tentative truce with one another, the fragile colonial serenity was not meant to last.

The peace between the orcs and humans was shattered by the arrival of a massive Alliance fleet in Kalimdor. The mighty fleet, under the command of Grand Admiral Daelin Proudmoore (Jaina's father), had left Lordaeron before Arthas had destroyed the kingdom. Having sailed for many grueling months, Admiral Proudmoore was searching for any Alliance survivors he could find.

Proudmoore's armada posed a serious threat to the stability of the region. As a renowned hero of the Second War, Jaina's father was a staunch enemy of the Horde, and he was determined to destroy Durotar before the orcs could gain a foothold in the land.

The Grand Admiral forced Jaina to make a terrible decision: support him in battle against the orcs and betray her newfound allies, or fight her own father to maintain the fragile peace that the Alliance and the Horde had finally attained. After much soul-searching, Jaina chose the latter and helped Thrall defeat her crazed father. Unfortunately Admiral Proudmoore died in battle before Jaina could reconcile with him or prove that orcs were no longer bloodthirsty monsters. For her loyalty, the orcs allowed Jaina's forces to return home safely to Theramore.
