A pixie (also called pisky, pixy, pixi, pizkie, piskie, or pigsie in parts of Cornwall and Devon) is a mythical creature of British folklore. Pixies are speculated to be particularly concentrated in the high moorland areas around Cornwall and Devon, suggesting some Celtic origin for the belief and name. However, the word 'pixie' (under various forms) also appears in Dorset, Somerset and to a lesser extent in Sussex, Wiltshire and Hampshire.
Similar to the Irish and Scottish Aos Sí (also spelled Aos Sidhe), pixies are believed to inhabit ancient underground sites such as stone circles, barrows, dolmens, ringforts, or menhirs. In traditional regional lore, pixies are generally benign, mischievous, short of stature, and childlike; they are fond of dancing and wrestling outdoors, which they perform through the night.
