|Book||The World of Ice & Fire (mentioned)|
Lucifer 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. Lucifer had a brief, inglorious reign before being put down by the power of Storm's End. His connection with the extinct Justman dynasty is unconfirmed.
