Once Upon a Time in Faerûn
Icewind Dale was an arctic region, along the northernmost part of the Sword Coast. The region was first populated when Northlander longships reached the region during the last centuries of the Illefarn empire. Initially settling on the islands, the northlanders eventually would found Icewind Dale. The region is mainly populated by fishermen, craftsmen, rangers, dwarves mining the deeps for minerals and precious stones, barbarians, and merchants who tolerate the hostile climate in the hope of trading in ivory and gems. The region was home to a number of white dragons.
Icewind Dale was an icy tundra and the northernmost explored area of Faerûn. Its only permanent settlements were known as the Ten Towns, a confederation of a number of minor settlements cooperating with each other. The towns are built around three lakes, whose temperature even in the summer months is cold enough to kill a man are the only known places to find the Knucklehead trout, a fish whose bones are almost exactly like ivory. The only other notable feature is Kelvin’s Cairn, the only mountain within a thousand miles.
