The Hall of Chambers
The Hall of Chambers, a vast area, with a ceiling far above out of view. In this near endless seeming 'hall', door after door can be seen, each leading to a new area outside the boundaries of the physical plain. The doors act as gateways to pocket dimensions and can alter the landscape to suit the minds of those who enter.
History
A world unto itself, no one recalls who built the hall, nor how vast it truly is. Many have died trying to reach the ends. Even the halls Keeper, and guardians do not know the truth of the Hall.
Alignment = Chaotic Neutral.
Purpose - A place for people to train, spar and fight safely without endangering lives as the hall heals and revitalizes all upon completion of any task held within.
