"The redcap (or powrie) is a type of malevolent, murderous goblin found in folklore of the Anglo-Scottish border region. The redcap is said to inhabit ruined castles along the Anglo-Scottish border, especially those that were the scenes of tyranny or wicked deeds, and is known for soaking his cap in the blood of his victims.[1][2] He is also known as Redcomb and Bloody Cap."
