Faerie Mountains
Although there is relatively little on mountain peaks, there are more than a few fey to be found there.
Weather fey are especially fond of these places, and the Unseelie Court has a fair presence. The Seelie, however, are scattered and weak in these desolate climes. The fey of these places are reclusive and impersonal for the most part, and only a few of the most malicious Unseelie care to go forth and interact with mortals who come into their environs. Most non-fey inhabitants of Faerie are also surprisingly active in these empty places, especially Fomorians, linnorms, and giant eagles and other winged magical beasts.
