Seek out Oronok Torn-heart on the Shattered Shelf - north of Coilskar Cistern.
I do not know how we can acquire the spell that the spirits mentioned, <name>. Truth be told, I don't even know where we would start such a search.
<Torlok stares off in the distance, lost in thought.>
Hrm... It is a long shot but it might be our only chance. There is an orc that I have seen visit this area before. I spoke to him briefly once. He is a hermit that claims to live above Coilskar Cistern to the northeast. Seek out this orc, Oronok Torn-heart.
As I said, it is a long shot.
