The Frost-Ash Crags form a brutal northern barrier where the highest mountains of the Apex Peaks meet buried geothermal fire. Blackened glaciers crawl between volcanic ridges, while frozen caverns shelter clans, predators, and forgotten ruins. House Scyllagix, a feral white dragonborn war-house, controls the safest passes through hunters, barbarians, and berserkers. Settlements cling to heated stone and sheltered valleys, while every trade route crosses territory that can become lethal under a single changing wind.
