Talisman 4th Ed. - The Dungeon Exp. - Rules of Play says:
Talisman: The Dungeon adds a new Region to the game for heroes to explore. A custom-fitted map board and over 100 new cards bring this subterranean realm vividly to life. Five brand-new characters – the formidable Gladiator, noble Amazon, dashing Swashbuckler, enigmatic Gypsy, and sagacious Philosopher – are each brought to life with a superbly detailed plastic miniature, and offer fantastic new playing experiences. The players need to brave untold dangers, and discover what lies in the darkness beneath the world of Talisman!
