Several of the humans within the Champions' Hall are named after major characters from the Stargate series.
Prior to patch 2.0.1, the Champions' Hall was accessed through a portal which only allowed access to players with the rank of Knight (Rank 6). With the addition of the new honor system in patch 2.0.1, all characters can enter the hall, and as of patch 3.0.2, the Champions' Hall is no longer entered via a portal and is now simply a part of Stormwind City.
During the Zombie Infestation, zombies were able to open or close the door to the hall at will. Players could be trapped inside indefinitely, unless someone outside or inside became a zombie to reopen the door, with the door sometimes staying closed for extended periods of time. This glitch was never fixed before the Zombie Infestation ended.
Patch 3.0.2(2008-10-14): The Champion's Hall is no longer instanced, and the door cannot be shut.
Patch 1.7.0(2005-09-13): The Champion's Hall has a new load screen.
