King Lot

King Lot /ˈlɒt/, also spelled Loth or Lott (Lleu or Llew in Welsh), is a British monarch in Arthurian legend. He was introduced in Geoffrey of Monmouth's chronicle Historia Regum Britanniae as King Arthur's brother-in-law, who serves as regent of Britain between the reigns of Uther Pendragon and Arthur. He has appeared regularly in works of chivalric romance, alternating between the roles of Arthur's enemy and ally, and is often depicted as the ruler of Lothian and either Norway or Orkney.
