Corusk Mountains
The Corusk Mountains or just Corusks become less dangerous from the threat of humanoids and monsters the farther east one goes, but the unpredictable freezing fogs and mists that can sweep down from them in a matter of minutes are a hazard to any traveler. Most peaks here are permanently ice-capped, and while frost giants, yeti, and taer are not common, they are dangerous enough to keep most folk away.
