From the back cover: The Ierendi princess, Corinna, has disappeared. She set sail aboard a ship of the Minrothad Guilds - the guild's ships which have been pirated and plundered for many weeks. Trade is horribly disrupted as many ships leave, never to be seen again. The guild masters now call for adventurers of great skill and renown. They offer small fortunes to any who can help them discover who is pirating their ships. But most importantly, to any who can rescue the princess. Can you and your party of adventurers defeat the dangers which lurk in the dark depths of a terrifying sea? Or, will you find a watery grave within the cold confines of a murky sea floor? This game adventure contains special rules for underwater adventuring.
