Chaos Wastes
From RoR Wiki
The Chaos Wastes is the fourth tier zone for the Raven Host army. The outskirts of the Chaos Wastes are similar to an artic tundra, while further inward they become a warped wastland, full of mutated inhabitants and changed by the power of Chaos, even to the point of Time slowing down or speeding up, and the laws of gravity failing, sending chunks of earth into the sky.
