The trail of flowers that grow near SkorgrÃm's corpse have led you to Gormr, the Steward of Thorin's Hall.
'I heard one of the guards here talking -- down yonder is Gormr, the Steward appointed by Thorin Oakenshield before he left. Gormr is the reason we have come, and the leader of this Dourhand rabble you see all over the place.
'You are the well-spoken one in our party, ${PLAYER}. You might as well go speak with him and find out what he has done here...and why he has grown silent over the years.'
Gormr guards the door to the tomb at the Berghold, in the south of the Thorin's Gate area.
You should speak with Gormr and find out what you can about his initiatives as Steward of Thorin's Hall and why SkorgrÃm's body has been moved.
