The Brawler's Guild is the name for a number of underground fighting rings that have sprung up in recent times in Orgrimmar and Stormwind. Open only to those clutching a Blood-Soaked Invitation, these are brutal arenas where hardened adventurers can go to do battle against a range of special bosses. A unique solo PvE challenge, fights are performed in the centre of the ring for all to see, and success is rewarded with progression through the guild's ranks and access to even tougher opponents, as well as the grudging respect of your fellow brawlers.
