In the Horgon Era, this area was mined for gemstones, iron, and copper. The Mine of Gruordock was the most successful of these. Gruordock's famed blue emeralds, unique to the area, became a hot item in the markets of Thadir, Kathodrarg, and other holds of the Aerie.
In the First Epoch, the white dragon Amaglothorn unleashed a great ice storm on the Vale of Inzurakthol. The city-state of Gruordock, then of dwindling population, took in thousands of refugees, reviving her fortunes for a few decades.
In 867, Gruordock was sacked by a frost giant warlord, the first Jarl of Inzurakthol. Gruordock became the home of frost giants, ice trolls, a young pair of white dragons, both descendants of Amaglothorn, and an existing population that only continued to decline under their savage occupiers.
