Crusaders' Square is located inside Stratholme's Scarlet Crusade side, west from the Market Row. It is the location of the Scarlet Bastion, and is also where adventurers have to do battle against Timmy the Cruel. Numerous members of the Crimson Legion attempt to defend their holdings here, behind crates and rubble.
