Pixies (also Pixy, Pixi, Pizkie, Piskies and Pigsies as they are sometimes known in Cornwall) are mythical creatures of folklore, considered to be particularly concentrated in the high moorland areas around Devon [1] and Cornwall, [2] suggesting some Celtic origin for the belief and name - akin to the Irish sidhe, pixies are believed to inhabit ancient underground ancestor sites such as stone circles, barrows, quoits, Rounds or standing stones.
