Scourge plague spreads across Lordaeron

Full History

Lordaeron stood among the strongest human kingdoms after the defeat of the Horde, but its defenses were prepared for armies more readily than for a disaster growing inside its towns. The Lich King used Kel'Thuzad and the Cult of the Damned to spread plague through the population. What began as sickness became a terror unlike ordinary disease: those who succumbed could rise to attack their neighbors as undead servants of the Scourge.

The cult's use of infected grain made the threat especially dangerous. Food that sustained ordinary households became a means of carrying the plague, and the boundary between healthy community life and imminent catastrophe grew uncertain. Prince Arthas and Jaina Proudmoore traced signs of the corruption, confronting necromancers and the undead that followed in its wake. Their investigation revealed that an organized enemy was exploiting the kingdom's daily life rather than relying solely on open warfare.

As settlements collapsed, fear and urgency shaped Arthas's decisions. The catastrophe at Stratholme marked the breaking point of his campaign: believing the inhabitants would soon become undead, he ordered their deaths before transformation. Uther and Jaina refused to support the slaughter. Arthas's pursuit of the plague's masters carried him to Northrend, where his quest for vengeance drew him into the grasp of Frostmourne and the Lich King.

The plague's political effects were immense. Lordaeron's institutions and royal family collapsed, the Scourge occupied much of the former kingdom, and survivors formed rival movements struggling over the north. At the original World of Warcraft endpoint, the Plaguelands and the ruins of the capital still bore the consequences. The spread of plague was not merely the first battle in a conventional invasion; it was the mechanism by which a living kingdom was transformed from within.
