The Alliance Needs Iron Bars!

Well hello there, Mr. Fancypants, aren't you a sight for sore eyes. In case you hadn't heard while you were out there "adventuring", the Alliance has been gearing up for a war in Ahn'Qiraj and is in need of iron bars... a whole mess of 'em. Bring them to me in stacks of twenty. We can count on you, right, <class>?
