Synopsis: Clarence Shandon is adrift, both spiritually and literally, his ship, the Naglfar, having sunk suddenly while at sea. He manages to survive the wreck and when he makes his way to a floating spar finds another man already clinging to it. This man is Golias, a bard. Eventually, they manage to reach an island, apparently deserted.
