Question the nearby Razormane prisoner. If he's not there or unconscious, Togrik can revive him for you.
I suppose he'll come around with some cold water to the face. What do you think he'll tell us?
I'll secure him inside our livestock pen behind me here. I don't think he'll stay conscious long. Find out what you can about why the quilboar are attacking our farms! I'll leave the interrogation methods up to your better judgment.
