Mythic creatures

This article concerns mythic creatures that have been referenced in Warcraft sources but which have no lore describing their existence as actual races.

Fairy
Fairies (a.k.a. faeries) are mentioned on several items and spells including Fairy's Embrace, Faerie-Kind Staff, and Faerie Fire. We can also see them around fountains of health and fountains of mana in Warcraft III.

Gremlin
Gremlins are mentioned in Night of the Dragon, "Foul little gremlins!"

Faun
Fauns are mentioned in material concerning dryads. Most likely a typo of fawn. Dryads are said to have the lower bodies of woodland  gray fauns and the upper bodies (head, arms, and torso) of night elf women. In mythology fauns are closer to satyr. They are bipeds with goat-like legs and goat horns on their heads.

Ouroboros
Ouroboros is a mythological serpent swallowing its own tail.

See Ouroboros Belt.
