At some point in the not-so-distant past, you did one of the following things:
- Bought a ticket and boarded some sort of transportation: a plane, a boat, a train, something or another.
- Fell asleep and awoke to the smell of roses.
- Blacked out.
- Opened a door.
Something happened, at least, which resulted in a number of doors being flung open in unison, people standing around and noting that for a bus this looks rather...train-like, people being jarred awake from their slumber as the train rolls over a bump in the rails...chugga chugga bump...and/or comatose bodies.
The train itself appears to be fairly normal. There's a number of cars attached, with the usual assortment of sleeping cars, a dining car with kitchen (clearly marked 'do not enter'), a caboose and the front three cars also blocked from casual access. (The effectiveness of said warnings having yet to be seen. Also, the
music in the dining car is a bit...dreary.)
People attuned to the mystical might also notice something odd in the atmosphere...actually, anybody would given the fact that they were expecting to open the door to the...I don't know...the bathroom and walked into a train instead.
Also, there may or may not be random puzzles scattered about if people really look for them. Riddles and number puzzles and things...the 'do not enter' sign being (if you were to look closely) a sliding block puzzle which somehow, in some way, locked the door.
It seemed unlocking the mysteries of the train would require patience, skill, and/or Yu-Gi-Oh cast who weren't fixated yet on cards.
