Luramin's Knowledge (history): 1d20 + 10 ⇒ (10) + 10 = 20
Luramin strokes his beard as he thinks. Hmm. No, I'm sorry; I can't recall anything about why the warden's wife was at the prison--although Jorfa was around back then, so she may even remember. You know Jorfa? The dwarven smith, works at the Forge just across the way. I'd try there, if I were you.
You can see that Luramin, too, is now curious about why you are following this particular line of enquiry--but at this stage, he doesn't bring it up.
