From the back cover: After a successful plunder of the Urchinn Isles, a well deserved night of drinking is in order, during such you trade stories with a local "antique dealer" who tells of a well-financed acquaintance who is organizing an archeological dig. The "antique dealer" goes on to explain that his friend has unearthed a forgotten portal which accesses the island tomb of the ancient Sea Kings (guarded by legendary beasts, of course). The treasures are said to be plentiful and there is rumor that a peculiar magic sword was swept up from the depths to find its resting place in the halls of Blackstone Island.
