King Lot, the King of Lothian, is the preeminent king of the north. He comes from the northern islands of the Orkney Islands, but rules over Lothian. He also has alliances with many Pictish tribes. Though Lot is dominant, the rulers of most of the other British kingdoms have not submitted to him.
His queen is Margawse. They have at least three sons: Gawaine, Agravaine, and Gaheris.
