A steam-powered auctioneer has been added to the Dalaran Like Clockwork engineering shop, allowing access to one's faction auction house. The steam-powered auctioneer was programmed with a superiority chip, and will only interact with grand master engineers.
Forget that rogues can eat me in one faceroll, or that paladins can solo ANYTHING. This is the only thing worth fighting for in the whole of WoW. I want a dalaran auctioneer too, dammit!
