Quoted By:
You can't stop yourself from wondering what other horrible surprises await you in the castle. You have been shown such a small segment of it... the fact that it goes underground into the pillar on which it stands increases its interior size dramatically, but you did not get to see how far down it went, as you were lead back up the stairs after visiting the hall of bones.
Instead of taking you back to the main hall, Strahd continues to lead you 50 feet up the staircase, taking you to the second floor of Castle Ravenloft, where there is another plateau with a doorway. You do not go out this door - instead you continue climbing for another 40 feet, ascending to the third floor, where you reach another exit to the stairwell. It continues further above this, but Strahd leads you to follow him through this door, which is illuminated by fluttering torches.
