Lake Wintermist

The fog that blankets Lake Wintermist is a year-round phenomenon, belying its name. The lake is inhospitable for most creatures, but those that thrive in frigid climes. White dragons frequently appear in the northwestern part of the lake, particularly in the dead of winter when they seek out mates. The lake provides ample supplies of fish for the Tigerclaw barbarians of the Winterbole Forest and a few homesteads along its southern shore. From time to time, someone passing through this area might come across a pair of angry trolls. The twin troll brothers Hurly and Burly both lair in caves not far from the lake—despite the fact that they can't stand each other. When they get into one of their family feuds, anyone who crosses their path could become a target of their rage.
-Mistwatch: Huddled against a hillside on a stony shore, Mistwatch has an exquisite view of Lake Wintermist’s cold water. A sleepy town, blessed with riches pulled from the unyielding stone in the nearby Cairngorm Peaks, grown rich from timber cut from the Winterbole Forest, and fed well on trout and salmon drawn from the clear, mist-covered water, has grown eerily quiet in recent months due to an undead curse. Mistwatch, totally covered in mist, is in the process of transforming into a domain of dread.
