Helm's Bed Lake is a smallish lake in southeastern Dun Morogh. Although the lake has mostly frozen over, a hole in the ice is maintained at all times in order to provide access to fresh water. While travel across the lake itself is quite safe, the surrounding area is crawling with dangerous wildlife and stray troggs. As if that was not enough, Dark Iron dwarves have also taken control of an abandoned building south of the lake, and will attack anyone who wanders too close.
