"A NEW GUEST HAS ARRIVED"

You hear these words before waking up in a white room which has a wrought iron door in the middle of it. The door has number 430 carved on it

As you observe the surroundings, even though there is not much to see, you notice that number "431" is imbedded on top of your hand

When you try to open the door, which seems like only thing to do, a serpent appears behind you

"Welcome to my manor, guest"
