Game description from the publisher: As the Great Houses head to sea, A Game of Thrones: The Card Game - The Pirates of Lys – the third Chapter Pack from the "A Song of the Sea" cycle – develops deep synergies between their characters, events, and locations. The naval challenge enhancement features prominently, appearing on several characters and interacting with new events and locations. Finally, a new agenda promotes the cycle's themes of naval exploration and encourages radical new deck designs.
