It is a large stone circle with water flowing off of it. It is reached by a bridge which falls after someone travels across it. There are rocks hovering around the ring.
Vexx can challenge him to a fight here. If Vexx falls he loses. If Sumo Kin falls he will grab the edge, pulling himself back up, and making part of the ring crumble.
There is a Wraithheart hovering above the ring. If Sumo Kin is defeated, it will go to Vexx.
