Caina, one of the Nine Hells, 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. The position of ruler is currently being fought for.
