Nymphs

Nymphs are nature spirits that live in the trees and waters. They are capable of leaving their tree and watery domains and assuming a physical body resembling human form. There are two types of nymph, Dryads who dwell in the trees and Naiads who dwell in the rivers, streams, and wells. They are so spiritually tied to their places of nature that, if it is destroyed, the nymph bound to that place dies with it. They are capable of consorting with human men and women, and can produce children with them. In The Magician's Nephew, one female nymph was seen with two fauns, a dwarf, a bird, and a hare as they welcome Digory and Polly. Nymphs were later seen in the coronation where they worship the first King and Queen of Narnia. In The Lion, the Witch, and the Wardrobe, many Nymphs were seen as stone prisoners in the White Witch's courtyard where Edmund was passing. Nymphs were seen in Aslan's camp as they welcome the Pevensies and the Beavers just as they were going to see Aslan. It is uknown if nymphs were present in the First Battle of Beruna, but are later seen in the coronation as the Pevensies become the High Kings and Queens of Narnia, so it is more likely than not they fought.

There are also evil Nymphs that are called Nymphs of Poisonous Plant that appear in The Lion, the Witch, and the Wardrobe.
