For centuries, the Subterranean Realms have supported an uneasy truce among the Empire of the Dark Elves, the Dominion of the Trolls, and the Kingdom of the Dwarves. Now some mysterious force has destroyed that truce, and open war has spilled into the lands above and below. Will your alliance discover a way to end the War in the Deep, or will you exploit the conflict to further your own ends? Each Adventure Pack includes approximately 40 - 60 cards, 1 - 3 punchboard sheets , and 1 rules booklet. Each Adventure Pack adds a new narrative story arc to the game, and each alliance can choose the ways in which it wishes to engage each particular story arc. These packs are a non-linear way to add story content over the course of an entire campaign (solo, cooperative, or competitive) and should keep the game challenging as the heroes spend Campaign Points between adventures.
