Goth variants of Nymph, Seelies. Nymphs in cold climates were often known to hunt upon the backs of wolves.
An unseelie nymph was a twisted relative of the nymph that delighted in the destruction of natural beauty. Their beauty, while rivaling that of their good cousins, was not quite the same; it was gothic with the occasional glint of malevolence in their eyes or smirk betraying their intentions, and it was easy to miss. Unseelie nymphs that favored forests had black or brown hair, while those that favored aquatic environments had blond or blue-green hair.
Personality
It delighted unseelie nymphs to destroy or twist all that was good and beautiful, corrupting it to their dark, gothic tastes. They maintained an innocent demeanor at all times, never overtly betraying their true colors.
Unseelie nymphs were extremely particular about their chosen environment; a forest unseelie nymph would stay away from lakes (even those she befouled), and an aquatic unseelie nymph kept her distance from forests, never dwelling willingly in the other's environment.
Any creature that laid eyes on the unseelie nymph was at risk of falling in love with her, an effect well likened to being charmed; men so affected were known to be more vulnerable to the nymph's corruption and especially pliable to her orders. This effect was so intense that even Elves were at a fair risk of being afflicted.
