Exploration Stage: Expedition
From: Conductor
Description: I wonder why I was chosen to guide that train... By the time it reached the last stop, the train was empty. All the passengers had already gotten off. And when we arrived at the station, there was no one there. People seemed to have disappeared without anything... some luggage was still on the carts. See how many suitcases were left there?
Completed: See, I told you, didn't I? The luggage is still here. That day, I was looking around to see if there were passengers who had forgotten their luggage. Then the train I was on disappeared like a phantom.
