The Frostflow Lighthouse is located in the north of Skyrim, west of Winterhold and east of Dawnstar. Some potatoes (×4) and leek (×6) are being grown just outside. The lighthouse is the site of a quite gruesome family tragedy, where strange noises in the cellar turn out to be a deadly threat. Via the various journals and notes the story is told.
The brazier is located at the top of the ladder upstairs at the lighthouse, along with a large chest requiring Habd's Lighthouse Key.
There are a few bear traps leading down to the cellar. In the cellar proper is a tanning rack and a number of barrels and shelves. There is also an opening in the wall leading to icy caves. There are also some chaurus.
 Frostflow Abyss
The Frostflow Abyss is a series of icy caves where the bodies of Sudi (imprisoned) and Mani are found in a falmer (×6) camp. With Sudi are a Bloodstained Note and a Scrawled Page. A few Frostbite Spiders (×2) may also be about.
