Guardhouse

The Guardhouse is a room found behind a locked door in Karazhan and which only recently became accessible to players — during the Scourge Invasion world event precursing World of Warcraft: Wrath of the Lich King. Within the chamber are several containers filled with what seems to be blood. The room is also the location of Prince Tenris Mirkblood and the quest item Orders from the Lich King.
