The Cult of the Damned began breeding a plagued dragonflight within the Scholomance, another method of spreading the Plague of Undeath throughout the land, during the Scourge's invasion of Azeroth. They were unable to get suitable numbers of them before the Scourge fractured and was driven back into the Plaguelands and Northrend. Now, the remaining necromancers of the Scholomance continue their work and hope to unleash the plagued dragons on the world. However, the Argent Dawn has caught wind of their activities and plans, and works to destroy the abominable plagued dragons before they can be deployed.
