Once Upon a Time in Faerûn
Kelvin’s Cairn was a free-standing 1,000-feet-tall mountain fronted by a river valley about as deep as the mount was high. The mountain top was always capped with snow and ice even through the short summer. The mountain was the only peak within a thousand miles, even though it appeared as merely a pile of loose boulders.
Barbarian legend held that Tempus defeated the frost giant Kelvin in this spot and gouged out the rocks here and piled them on top of his corpse. More likely, however, was that it was an extinct volcano. The valley to the south of Kelvin’s Cairn was the home of the Battlehammer Clan of dwarves. From underneath this vale, the dwarves mined iron and forged it into well-crafted weapons and armor that were then sold in Bryn Shander, located at the other end of the valley.
