who was the lord of rooks rest

Rook’s Rest was a castle held by House Rosby in the Crownlands, so the “lord of Rook’s Rest” would have been the Rosby lord in that period. In House of the Dragon discussions, the name most often tied to the castle itself is the Rosby lord, not a separate named “Lord of Rook’s Rest”.

Quick Scoop

• Rook’s Rest was not usually ruled by a famous standalone lord in the way major lordships are discussed.
• It was associated with House Rosby, a Crownlands house.
• In the battle there, the castle became famous for the fighting around it, not for a specific lord of its own.
