In Arthurian legend, King Lot is generally the king of Lothian and sometimes Orkney and Norway
GM as well. There is historical basis as there appears to have been a king in the fifth century in the Lothian area who was headquartered near Edinburgh.
RC
Lot is typically considered the father of Sir Gawain, one of the Knights of the Round Table. Depending on the source, he is married either to King Arthur's half-sister Anna GM or Morgause. TM There is even an argument to be made that he was married to Morgan Le Fay. RL
Lot is sometimes portrayed as an ally of Arthur's GM and at other times the leader of a rebellion against him. Some accounts have Lot taking over the British armies after Uther Pendragon, Arthur's father, became ill. However, when Uther died and Arthur was named king, Lot rebelled. EBK In some versions, Lot is defeated at Bedegraine and then becomes Arthur's ally. PV In other versions of the story, Lot remains a bitter enemy of Arthur until he is killed by King Pellinore. TM

In Otter and Arthur and the Round Table, Lot is King Arthur's primary enemy. Lot had a bitter rivalry with Uther Pendragon, Arthur's father, and maintained his desire to destroy the family after Arthur came to power. This hatred against Arthur is deepened when Lot marries Arthur's sister, Morgan (a composite of Anna, Morgause, and Morgan Le Fay). They bear a child, Mordred, who will maintain the hatred against Arthur.
