Eastern Callahax is dotted with ruined castles. Remnants from hundreds of years of war.

The plains of Callahax are the farthest northern duchy in Thessan and is protected from the Cainscape by the Standing Stones of Frey, ancient markers of a kingdom long past. The stones provide an intense heat, so powerful that few can withstand being close enough to see them. The heat provided by these stones prevents more Southern regions from being overtaken by the glaciers of the Northern wastes. As a result, Callahax is known for having large regions of marshes.
