Now, turn back to the door and walk towards a small corner between the wall and the door frame. Walk towards it slightly, don’t get too close. If you walk within few steps of the door and look to the right you’ll see a fire. You should see an open door where a man with a white pointer over his head is waiting, do not go through this door.
On Skyrim when the Dragon first appears at the very beginning of the game merely run up the stairs and wait for the Dragon to break through the wall, after the Dragon breaks the wall and your Runaway Comrade tells you to jump, make the jump and walk and go down through the holes in the flooring.
