Hidden deep within the forest lies Crystal Lake... The only race that knows about it would be the Wood Elves. It's a small lake north of the Corbolo River's source and southwest of Cheydinhal. Besides Vaermina's Shrine on its shore, and nearby Muck Valley Cavern, there is little here of importance. There is one nirnroot growing by a rock on its north-western shore. The amazing thirty foot drop... Was created centuries ago by a falling astroriod, which created Twin Falls.
