Talisman 4th Ed. - The Cataclysm Exp. - Rules of Play says:
Exploration in the remnants of a shattered world! It has been countless ages since the great Cataclysm left the world of Talisman on the brink of destruction and now, from the ashes, civilisation rises once again. The Cataclysm expansion introduces an entirely new main board to replace the one found in the base game. Players explore the broken lands and meet its many new and varied denizens with over 150 cards and five brand-new characters. Who can best their opponents, secure the crown, and seize destiny?
