So you need to bring the return mail back to Mount Hyjal, eh? There's a little problem... Y'see, someone came through here and ransacked the outgoing mail just a few days ago! Probably looking for money in the mail. Ran off into the hills somewhere north of here and never came back. Probably got torn apart by a yeti or something! Anyway, if you wanna bring back the mail, you're gonna have to go get it first!
