After I get King Olaf's Verse and run torwards the Sealed Door, the Ghost will not open it. Instead, he simply stands there and does nothing. I have tried using the tcl command to no-clip through the door and continue with the quest, but it will not work inside Dead Man's Respite. I have also tried using the disable command on both the Ghost and Sealed Door, but if I do that, then the boss fight between the Ghost and the Draugr will not occur, plus the Draugr will not awaken at all, nor will the boss emerge from his coffin.
Discussion in this thread is no longer necessary, thanks.
I have long since completed this quest and have become a member of the Bards College through clever use of console commands. Nonetheless, I appreciate any and all help that you gave me. A moderator or admin is now free to close/lock this topic since it is no longer necessary.
