The Plagueworks is a laboratory for creation of potions, vials and containers of the Plague of Undeath and blight slimes. It is also the factory where several Abominations and horrific scourge creations are made. Professor Putricide is the leader of the Plagueworks. In order to access his lab, adventurers must first turn the Gas Release Valve and the Ooze Release Valve. The two valves however, are guarded by two fleshbeasts: Festergut and Rotface.
The Plagueworks opened on January 5, 2010, 28 days after the opening of Icecrown Citadel.
