After having obliterated the Briarwolves' camp at Farlorn's Hope, the path to Greyfell was found to be blocked by the rune warrior. She talked to the dwarf called Bork Gorinson, who revealed her, that he might be able to get rid of the rockslide blocking the path. He suggested to ask Jon Farlorn of the Free Traders for help in getting the required materials.
The following ingredients were needed by Bork:
- Firepowder
Could be provided by Jon Farlorn by crushing three Stones of Eternal Fire. - Sulphur Binder
Could be bought from Jon Farlorn for 1 gold. - Salpeter
Could be provided by Jon Farlorn by bringing him a phial of Demon's Blood. - Phial of Vulcan Glass
Could be found at the dragon Faurung northwest of Farlorn's home.
Once the rune warrior had brought him all required ingredients, he headed out to the south-west and placed an explosive. Said explosive got rid of the rubble blocking the path to Greyfell.
