From the back cover: On the seacoast of Prax a fishing village is being terrorized by unknown terrors from the Deep. The Chief Fisherman has raised a call for hearty adventurers to seek out and destroy the unknown menace that has sunk their boats and eaten their people. Monstrous Serpent tracks have been spotted leading into a nearby Sea Cave complex. Who knows what dangers and riches live therein... This incomplete RUNEQUEST! adventure includes background, cave complex maps, room descriptions, and a cast of dozens of foes. Made for game Referees, solitaire role-players will also find this expedition a challenging and absorbing one. From the "Introduction" section: EDITOR’S NOTE: This scenario was found in the Chaosium files after having been set aside, unfinished, in the late 1970’s. It remains unfinished to not diminish its “work in progress” charm.
