The War of Five Kings is the first monthly installment of fixed cards for the "A Clash of Arms" cycle for A Game of Thrones: The Card Game, based on George R.R. Martin's bestselling Song of Ice and Fire saga. This Chapter Pack contains twenty different never-before-seen cards designed to augment existing decks and add variety to the A Game of Thrones metagame. (The first edition of this Chapter Pack included only one of each character card, while the second edition includes three copies of each card.)

The five kings have summoned their mighty hosts, and their queens are protected by guardian knights. The realm is past the time for treaties; the hope for peace is lost. Now is the time for the champions of Westeros to prove their worth on the field of battle. Now is the time for war.
