Flooded Undercity Arena

Publisher's blurb:

Heavy stone pedestals mark the outskirts of the arena, angelic statues standing upon them grasping chains or holding swords.

Many stone pillars hold up the cavernous roof over the crowded stands and platform that looks down upon the contestants. The floor has fallen away In many places and been flooded by excess wter from the nearby sewers. Sharped wooden spikes have been placed all along the walls and around many of the pillars within the arena while bloody marks have been left upon the stone from previous battles.

A large symbol has been carved into the stone floor, a mark of the owner of this place as well as a functional trap door that leads to the elevator used to get the combatants access to the arena.
