Nymphs resemble elven women, but are unfathomably perfect and beautiful. They are so physically attractive, in fact, that the slightest glance can stun a person, drive them mad, permanently blind them, or even kill them. Nymphs are able to suppress this effect if they choose to, however.
Nymphs prefer attractive aquatic environments, such as a secluded cove or sandy beach, and are mostly solitary, though sometimes live in groups. They might assist a group of adventurers, or have a love affair with a man who wanders into their midst, but there is little contact between them and civilization otherwise (this is typical for a fey). Nymphs hate ugliness and evil.
