Characters
Adrian Vale, 28 years old. British. A calm man in a suit. Composed and caring, he naturally becomes the leader. However, he is reluctant to talk about where he was just before boarding the train.
Luca Moretti, 22 years old. Italian. Friendly and lacks personal space. A cheerful mood-maker, but occasionally makes comments as if he knows this train.
Leon Hartmann, 25 years old. German. Blunt and highly cautious. From the moment he woke up, he has been suspicious of the train and the other three.
