Down in the Flood! As the adventurers work to track down the missing colonists, the trail leads to a nearby island. There, they discover the submerged ruins of a cathedral dedicated to a now-dead god; the site has become a lair of an ichthyic monster and its cunning minions. The adventurers must fight their way through flooded chambers and vicious monsters to rescue the kidnapped colonists and learn of a greater threat to the region—and to humanity as a whole.
