Lady Rhea Royce, also known as the Bronze Bitch, was the head of House Royce of Runestone and the Lady of Runestone under the rule of King Viserys I Targaryen. She was the first wife of Prince Daemon Targaryen.
Rhea and Daemon had no love for each other, with Daemon nicknaming her the Bronze Bitch, a reference to the ancestral armour of House Royce. She died childless, it is unknown if this was because she was barren or Daemon preferred the company of other women.
Rhea died during a hawking accident. After her death Daemon requested to be made Lord of Runestone, but this notion was rejected by Lady Jeyne Arryn, meaning the title instead passed on to Rhea's nephew.
