Talking to a Ghost

From: Conductor
Description: There’s very little time before the train leaves! We’ve found a lot of strange objects, but how to connect them and understand why passengers turn into ghosts when the train takes them into the fog? What if we ask them? Lend me some artifacts to summon the ghosts.
Completed: I’m no medium, and I don’t know how it works, but I’ll try to put the artifacts next to the objects related to the passengers’ ghosts.\n It worked, the conductor’s ghost appeared! He says the fog turns passengers into ghosts, draining their memories and emptying their souls.
