During the exploration of an ancient Jistkan ruin in Katapesh, the automaton Star goes missing, leaving their archeologist companions worried for their safety. The head archeologist calls upon the Pathfinder Society for assistance, but warns the agents that arrive that the ruin is filled with dangerous creatures and traps and that they should be careful while exploring. A strange frozen automaton meets the Pathfinders on each floor, slowly pointing the way deeper and deeper into the ruin. Will they find Star? Or does the automaton have more malicious motives?
