Yeti

Yeti, large bipedal white furred creatures, can be found in a number of areas in Icewind Dale. Though their existence was often suspected, as dale dwellers came across strange footprints, it was Mirek of Kuldahar who first encountered them. Visiting The Vale of Shadows in 1281 DR with his brother, he encountered a tribe of the creatures, who attacked the two men. His brother was killed, but Mirek was able to flee back to Kuldahar, followed by the yetis, who proceeded to invade the town.

A visiting group of outsiders trapped in Kuldahar by an avalanche, is said to have helped the townspeople to successful repel the invasion.

The Kuldahar yetis appeared to have a social order, with a chieftain, and inhabited an ice cave in The Vale Of Shadows. Other groups have since been reported in Wyrm's Tooth, including in Joril's Cave, and Gloomfrost.
