Enter the Scarlet Halls.
King Anduin Wrynn has requested that any able-bodied adventurer head to the Scarlet Halls, northeast of the Undercity, immediately!
Crusader activity has picked up throughout the plaguelands and elsewhere. His majesty fears a revival is underway. Scarlet zealotry will not be tolerated near the King's lands!
Enter the Scarlet Halls and assault the armory and library before they can mobilize.
