Fairies were a fae species of supernatural beings resembling diminutive humans with insect-like wings. They lived underground, along with the Slimefolk, the Ravenclan, and creatures that resembled leaf-blowers. The Slayer Organization helped the four races band together and defeat a horde of demons, led by Yamanh of Hoht, who were coming from deeper underground to attack both them and the surface world.
Following the End of magic, some fairies ventured to the surface; others lived in London at Alasdair Coames' apartment where they were protected, and one such fairy was sent to San Francisco by the spirit of Sineya to send Buffy Summers and Willow Rosenberg a message on how to reverse the end of magic and save the world.
