The lubber fiend, Lob, lubberkin, lurdane or Lob Lie-By-The-Fire is a legendary creature of English folklore that is similar to the "brownie" (or "Urisk") of Scotland and northern England, the "hob" of northern England and the Scottish Borders, the Slavic "domovoi" and Scandinavian "tomte".
The lubberkin is typically described as a large, hairy man with a tail who performs housework in exchange for a saucer of milk and a place in front of the fire.
But so soon as my back is turned he will be forever answering the door and peeping out into the street to gather the mongrel boys about him.
'Tis a most foul Lubber Fiend to keep about an honest house, plaguing decent folks withal!
A creature called a lubberkin appears in The Witcher 3: Wild Hunt, in which it is a type of protective household spirit (a kłobuk [pl] from Slavic folklore).
