The Ruins are the domain of Chaos, the god of Decay. This region of Urth encompasses the ruins of what was once a thriving metropolis. When the meteor came in contact with the planet, the cataclysms wiped out the modern cities and destroyed all modern technology. The derelict skyscrapers have become a place for the newly evolved lifeforms to reside in.
The arena is set near the dried-up banks of a river near the ruined city. A beached ocean liner lies to the left, and to the right is a downed power transmission line.
