According to some old journals we found in the depths of Bitterstone Mine, Durak hid a stash of cannons somewhere nearby. They're likely useless after all these years, but we could scrap 'em for parts to fix our own guns.
My kinsman Grulfen Stonebeard's in charge of the search for the forgotten cache. He set off a few days ago, sure he was on the right track. You find him and you might find the cache.
