Starr, a veteran instance clearer, enters the Train K3016 dungeon. Players receive instruction: abide by train rules, travel to Carriage 1 to find the conductor and clear the instance. This rule was a fatal trap. A hidden mechanism: "choose your travel direction based on abnormal movements in the carriages"; wrong choices stack brutal killing rules. Players perish, suspicion and sacrifice run rampant. Starr survives traps, only to discover the conductor was never in Carriage 1.
