Speak with Foreman Oslow in Lakeshire and ask him for Rethban Iron Ore.
I've been meaning to finish my copy of The Stresses of Iron, but...
Well you see, I make my own ink for books I copy. It's my own recipe; it doesn't run or smear, and it dries very quickly Unfortunately, it dries too quickly! My last batch dried up before I could finish the copying job, and I haven't had the chance to make more ink!
To make more I need Rethban Iron Ore from the Redridge Mountains. Foreman Oslow in Lakeshire is my usual supplier.
You need what?? Maybe you haven't noticed, but we're busy fortifying Lakeshire's defenses and repairing damage from recent orc attacks. If you need Rethban Iron Ore, you'll have to get it yourself!
