Thane Rollo,
I understand the trials of leadership and that you are undoubtedly an extremely busy dwarf, so I'll keep this rather short. I am a Transmuter who's doing some research on a metal called "Harmonium" (or "Zabar's Treat" on the surface). If you or your clan were able to find a sample somewhere near Sanctuary, I would greatly appreciate it. I'm quite close to discovering a way to prove that a specific kind of mineral is Harmonium, and when I do I will share it with you.
I'm afraid that neither the metal itself nor the fruits of my research would be terribly useful to your Stouts. I am not a wealthy man by any means, but I could spare up to 250 crowns for your aid, as well as my devotion to your cause. For the time being, I only need the item found for the time being so that I can collect a sample.
If you were to aid a researcher who's working to improve conditions, my opinion of your Clan (and the opinion of anyone within earshot) would likely be quite favorable.
Sincerely,
Lucius Foxmantle Crone, Room Two
