Cania (or Caina), the Eighth Hell, is an unimaginably cold wasteland, where few living things can survive more than a few moments in an unsheltered area. Huge fast moving glaciers crash around the layer sending snow and ice up in the sky. It is dominated by intense, freezing cold, and is extremely hostile toward those who are unwelcome on the layer, which includes nearly every being that enters. It is the home of the gelugon baatezu.
The layer is ruled over by Mephistopheles, from his great citadel of ice Mephistar. It sits upon a giant glacier called Nargus, the movement of which is controlled by Mephistopheles himself. Inside Mephistar huge heated baths and fire warm the citadel, providing quite a comfortable environment.
Many things lie hidden under the ice of Cania: vast lost cities, frozen armies of creatures. The primary portal to access Nessus is through a gaping hole guarded by 9,999 gelugons. At the bottom of the dizzyingly deep pit is an icy body of water and 1,001 fathoms deep in that is a silvery portal to Malsheem.
