You are the concierge of the hotel aboard the Sky Express, a magnificent airship. Unfortunately, all your guests are axe murderers, werewolves, spies, mad scientists, cultists, and so on. Your job is to keep them from killing each other.
You can only pick which guest stays in which room. During the night, the guests activate and get up to all kinds of... things. If you placed them correctly, their activities will cancel each other out in a series of lucky escapes. If you did not, an entertaining catastrophe ensues.
