Lady of Myr
The Lady of Myr is a trading galley which presumably comes from Myr.
A Feast for Crows
While in Maidenpool, Brienne of Tarth and Podrick Payne pay a few pennies to stay in one of the galley's cabins for a night. The Lady of Myr has lost her mast and half of her crew in a storm, so her captain is appreciative of the two visitors.
