The enormous Gray Mountains dominate the eastern reaches of Gulnir. The high elevations, brutally cold weather, and fearsome frost giants drive away all but the most hardy. Yet Gulnir depends on the Gray Mountains as its only reliable source of ore. Highpoint funnels the ore through the Cheviot Pass down to Cheviot to distribute throughout the kingdom.
Various explorers have attempted to scale the Gray Mountains and see what lays beyond, but if any succeeded, they never returned. Throughout the history of Gulnir, countless expeditions have been mounted to find a pass besides Cheviot Pass, and all have failed.
