Garrosh's Autograph

They say that Garrosh Hellscream is one of the greatest heroes in the Horde! When I grow up, I want to be a hero of the Horde too! Do you know Garrosh, <name>? Could you do me a favor, please? Could you get his autograph for me? I dunno how to ask him, and he probably wouldn't listen to someone like me... but you! You're an adventurer, like him! I bet he'd give you his autograph easy! Please?
