Sixty miles northeast of Fort Valiance, the Stonetalon Range breaks open in a narrow pass forming the primary overland route between Morgath and the Frostvall Clans. It is here that Frostwatch Keep stands — a masterwork of military architecture carved as much from the mountain itself as from dressed stone.

The Keep has never fallen. Three times in the past century, the Frostvall Clans have attempted siege. Three times, the mountain has answered with stone and blood. The pass narrows to scarcely sixty feet at its widest point — any attacking force finds itself funneled into a killing ground with crossfire from multiple levels.

The same pass that serves as gateway for Frostvall raiders is also the only viable overland route for legitimate trade. The clans' furs, amber, and crafted goods flow south through the Keep's controlled passage. In turn, Morgath's manufactured goods, grain, and luxuries flow north. The Keep profits from tolls and tariffs, but the arrangement creates abiding tension — how does one police a border against warriors who also bring legitimate commerce?
