Aemma Arryn

Daughter of Lord Rodrik Arryn and Princess Daella Targaryen, wed to her cousin Viserys before he came to the throne. She bore him Rhaenyra and several stillborn or short-lived sons, and died at the birth of the last: a son, carved from her body by the maesters on Viserys's command, who outlived her by less than a day.
