Game description from the publisher:
The House of Black and White introduces sixty new cards (three copies each of twenty different cards) that further enrich the "Beyond the Narrow Sea" cycle and its exploration of the people, places, and events of Essos. House Stark features prominently in this Chapter Pack, but players will also find a host of high-impact locations for each House, as well as an arsenal of Weapons and other attachments.
Meanwhile, The House of Black and White provides fantastic and deadly tools to players who favor the unique personalities of George R.R. Martin's A Song of Ice and Fire. The Many-Faced God may wait at the end of the road for all individuals, but two plots, a location, and an event allow players to make greater stories of the lives of those characters who stand unique in A Game of Thrones: The Card Game.
