|Died||In 51 AC, Maidenpool|
|Book||Fire & Blood (mentioned)|
Rosamund served as a lady and companion for Queen Alysanne Targaryen. When her queen was attacked by the order of holy sisters while attempting to bathe in the sacred waters of Jonquil's Pool at Maidenpool, Rosamund, like the rest of the queen's ladies, did not hesitate to put herself between the queen and her would-be assassins. Rosamund was stabbed in the stomach during the attack. The shouts alerted the Kingsguard who were guarding the entrance of the bathhouse, and the knights intervened and ended the assassins plot. Rosamund died a few days later from the wound.
