The Fair Folk are spirits that reside in the regular world (as opposed to the Otherworld) that generally have one of two major functions – guarding and caretaking a particular place, family or building; or embodying the essence of the creative processes, particularly in physical crafts such as carpentry, masonry, pottery and weaving. These were termed, respectively, elves and dwarves in Germanic mythology, and variations of the Folk include the Celtic sidhe and dusii, the Slavic leszi and vilas, the Greco-Roman satyrs, fauns and nymphs, and various house-spirits such as the brownie, the nisse, the tomte and domovoi.
