King Pellinore is the king of Listenoise or of "the Isles" in Arthurian legend. In the tradition from the Old French prose, he is associated with the Questing Beast and is the slayer of King Lot. His many children include the sons Aglovale, Lamorak, and Percival, and the daughter Dindrane.

King Lot, also spelled Loth or Lott, is a British monarch in Arthurian legend. He was introduced in Geoffrey of Monmouth's pseudohistorical 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. His literary character is probably derived from hagiographical material concerning Saint Kentigern, which features Leudonus as king of Leudonia and father of Saint Teneu.
