Following on the heels of Thunderstone Advance: Caverns of Bane, Thunderstone emerges into the deepest trouble yet.
The tunnels under the fortress at Cheah Dell are clear. The lost dwarven kingdom of Caligin is reclaimed. And the djinni lich, Mowtil, has been defeated, sealing the portal of black flame into Tala.
The adventurers have collected three more Thunderstones, and Doom's full plans are revealed. He has corrupted the heart of Tala, Dun Ordha. A monstrous army marches on the capital city, even as the final Thunderstone is revealed to be held by King Caelan himself. Can the adventurers race ahead of an army to save the city from a siege outside the walls and sickly corruption within?
Over 300 new cards, dividers, rulebook, and a poster map containing a board for a brand new co-op game, using existing Thunderstone rules!
