Unknown station (IC ONLY): Instead of a regular nightmare kingdom, this Stygian's kingdom is a long, winding train track with a single train travelling along it continuously on the move. It can travel through other nightmare realms and "pick up" passengers as well as "drop off" others. During the track, temporary landmarks such as very small stations and tunnels can be created. The kingdom becomes almost like an "aura" on the move: the tracks move where the train does and then rapidly disappear behind it, leaving nothing behind.
