The cards in this expansion are designed to augment existing decks and add variety to the A Game of Thrones metagame. This Chapter Pack features 3 copies each of 20 unique cards.

Forging the Chain develops more synergy for the Maester trait across several Houses, a key feature of the Secrets of Oldtown cycle. New support for the Maesters include Pale Steel Link, Maester Kedry, and Called by the Citadel. This Chapter Pack also includes deeper deck-building opportunities through cards like Jaqen H'ghar, Shireen Baratheon, and Riders of the Red Fork.
