The Stolen Keg

You've got to help us, lad. We were tasked with escorting a precious cargo to our fellow dwarves...a keg full of the finest ale you can get out here! Unfortunately, bird-brain over here fell asleep on the job! Those blasted orcs took our keg, and hauled it up into Dun Algaz where they're hiding. This can't stand! Now, while I stay here and try to convince this idiot that it was his fault, I'd like you to go in there and get our keg back. For Khaz Modan!
