Game description from the publisher:

Valar Dohaeris is the second Chapter Pack in the "Beyond the Narrow Sea" cycle for A Game of Thrones: The Card Game. It introduces cards and strategies meant to welcome new players to the game directly after the Core Set, as well as challenge the traditional thinking of veterans immured in the game’s shifting balances of power.

Meanwhile, as the Great Houses continue to expand their influence into Essos, Valar Dohaeris brings more of the Eastern continent's flavor. Two unique locations encourage decks that unite characters from rival houses, players continue their journey down the Rhoyne with four flowing River plots, and a host of new personalities arrive, ready to serve. Knights, Fools,
Allies, and Lords – all must show obedience and play their roles in the myriad battles and intrigues launched between rival houses as they seek to claim the Iron Throne.
