Mincham believes that Olnathron can be found in some ancient ruins in the western Fields of Fornost.
'I believe Olnathron is at Tham Lorn, some ruins in the western fields. I have heard dark rumours about that place of late, and it could well be the source of the evil stirrings in Fornost.
'My horse will take you there if you wish to go. You must be careful. You are a seasoned warrior, but this place is truly evil.'
Tham Lorn, in the western Fields of Fornost, can be reached by taking the horse from Mincham's Camp.
You should travel to Tham Lorn to confront Olnathron once and for all.
Olnathron can be found to the west of the graves of his wife and child.
Fearing for the strength of his will, Mincham has asked you to find and confront the fell spirit who has taken his wife's semblance.
Mincham awaits you at his camp.
Mincham will be relieved to learn that the fell spirit Olnathron has been sent back to the abyss.
