After several minutes, Dak approaches you. He's pushing a wheelbarrow containing a large sack and several other pieces of debris. "Not sure why you want this stuff, but here ya go."
As you look through the junk you find, among other things, a broken black shaft that appears to be a mate to the one Tor found. Kerrz, thanks to his familiarity with horses, also finds a few strips of leather with metal fastenings that he claims is part of a wagon harness for a horse or similar beast of burden.
