Country and County: Cornwall

In many old established mining areas throughout the world, there was a
long tradition of mine spirits, in Cornwall these were known as the
Knockers. They frequented the tin mines that formed much of local
economy in 18th and 19th century Cornwall. Knockers was not the only
name given to mine spirits others being Knackers, Buccas, and Spriggans

Spriggans is the name given to a family of fairies in Cornish folklore, they are the closely related to the Piskies, but were generally believed to be darker and more dangerous than their mischievous cousins. Whereas Piskies are generally described as being cheerful and fun loving, Spriggans are more spiteful and full of malice, directed at humans in the form of evil tricks.
