Turn right and go right toward the stairs. Walk across the room through the middle entryway. Go straight until you reach the room with the chandelier.
With the wall that doesn't have any doors on your right, exit through the doorway ahead of you and turn right towards the stairs leading downwards. Continue past the stairs and exit the room through the center archway of the three archways on the opposite wall. Stop once you enter the room at the end of the vaulted hallway.
Turn to the right and then turn right again immediately. Go the right and pass the table. Then turn left and go through the two doorways and stop.
