Gather 8 bundles of Composite Ore from the digs surrounding Galakrond's Rest and bring them to Xink at Nozzlerust Post.
Hello hello! The Scourge to the south are digging up some ancient dragon thing. I could care less why they're doing it, but they're pulling cartloads of composite ore in the process.
Go lift me a bunch of that ore. That stuff should yield a pretty penny for all the weapons the Horde are crafting.
