I Am Stuck

So after the dialogue between Axelus and the king and the doguns, I was teleported to a room. The quest book asked me to talk to the king and the dogun chieftain, but I accidentally pressed the "S" button so I left the place.
I went back to the portal and tried to enter Garaheth's mouth again, and start the whole thing over, but I can't get in.
So I am stuck in that realm and I find no way to finish the quest.

P.S. I know I can do /kill to leave, but that's not a problem. The major problem is I can't finish the quest because of an accident.


EDIT: I am sorry if I posted in the wrong section
