The War Room (also spelled war room and also known as the map room) is located inside Stormwind Keep, to the right and southeast of the central throne room from the main hall of the keep. Weapons of war line the walls, everything from blunderbusses to swords to even three cannons. There are areas piled high with books about military strategy and its signature map table at the room's center where Alliance military leaders plan their strategies. It is the location of all the battlemasters, which moved into this room from the throne room in patch 2.0.1. It is also here where players can turn off their experience point gain by paying Behsten.
In Battle for Azeroth, the map on the table in the center of the room has been changed to depict Azeroth with the Legion version of the world map. At the end of Battle for Azeroth, Fearbreaker was also placed here, before Magni Bronzebeard came and asked to get it back to fight against the forces of N'Zoth.
The room received a major redesign with Cataclysm. Among other things, it was moved to its former location beyond the northeastern door, behind the central throne room, to its current location to the southeast.
This room was opened up and had all the battleground masters placed within due to the Onyxia chain quest in which Onyxia called forth her minions to fight the player, causing low-level players not able to join a battleground until the fight was over.
