Trasgu
Region of origin: Spain
Related to goblins and kobolds, the trasgu are domestic spirits found throughout Spain and into northern Portugal. They may take up residence on farms or in homes and chiefly make their presence known by causing mischief such as moving items or making noises in the night but will also perform chores and be generally helpful if kept placated with a share of food and milk. Some are said to have a hole in their left or both hands to prevent them from stealing items from the houses they reside in, similar to the Catalonian pesanta. The trasgu will become attached to its family, following them if they move, so the only way to get rid of one is to assign it impossible tasks and, shamed by its inability to complete it, will leave in disgrace. The Cantabrian trasgu are more wild than their rural cousins, instead living in the woods and wearing clothes made from moss and bark to camouflage themselves as they play pranks on people who enter their forest.
