Balon Greyjoy, the self-proclaimed King of Salt and Rock, and his Ironborn lords, have seized on the death of King Robert Baratheon as an opportunity to renounce their oaths to the Iron Throne and take the "green lands" by storm. Now, raiders in their deadly longships have set sail to choke Westeros in the arms of the Kraken. A Song of Silence features the mysterious and power-mad Euron Crow's-Eye, as well as a wealth of synergy for cards with the Raider trait through cards like Longship Silence and Euron's Mongrel. As with every Chapter Pack in The Brotherhood Without Banners cycle, A Song of Silence includes never-before-seen cards for every faction and also continues the ongoing theme of this cycle by deepening the Brotherhood trait with cards like Hollow Hill and The Mad Huntsman. A Song of Silence will augment existing decks and add variety to the A Game of Thrones metagame.
