Havuk

okay so I checked the cart at the southwest portion of the mines and I did not find anything. I am currently using a person with 13 mechanics. Is the purple area supposed to be the cart itself? or did it come from the box in the same room? I dont remember since its been a while i looted that room. Nvm, I was only able to find it after getting that note from the frozen dwarf in the secret room of the great hall. Thanks for the heads up!
