An ancient stone arena that has withstood the test of time - and, somehow, all the battles it has seen. You are welcome to hold your duels in other rooms (unless asked to move), but this offers a specialized environment to really get down and open up a can of whoop-ass.
Whether you are going to be a fighter or just a spectator, remember: There's no limit to how violent things can get in here. No sex here, it's still an all-ages room.
NOTICE: Remember, folks - it's just RP. Don't let fictional events affect how you interact with people out-of-character, or you're going to have a problem.
