The archway

You walk out onto the courtyard and the first thing you see is people all over the place sparring with each other. You turn your head to the left and there is a big pit of mud and you can see people who have been defeated crawling out of it. On your right you notice a small tent and can here people moaning from inside. All in all the class seems pretty interesting so you decide to stay and give it a shot. What mystery awaits you? What fun will you have? You may never know unless you try it out...
