Lord Robert Vance was the head of one of the branches of House Vance four centuries before the Aegon's Conquest.
Robert claimed the title of river king or King of the Trident in the generations after the riverlands were conquered by the Storm King Arlan III Durrandon. Lord Robert had a brief and inglorious reign before being put down.
