The Horde Needs Tin Bars!
Bring 20 Tin Bars to Grunt Maug at the Valley of Spirits in Orgrimmar.
Lok'tar, <race>, I'm sure you already know that we're going to war at Ahn'Qiraj with the insects. But first the Warchief has decided that we're going to do something called 'prepare'. Though I'd rather be sharpening weapons and hammering armor into shape, I'm proud to have been chosen to be in charge of tin bar collection here. But I cannot do that without your help.
So I need you to go out and make tin bars and bring them back to me here. I think I'm going to need more than I can count.
You have my sincere gratitude. Your efforts in helping Cenarion Hold have shown true courage.
