Bring the Crate of Grimtotem Horns to Belgrom Rockmaul in Orgrimmar.
Ah, so I did mention a bounty, didn't I? Well, that'll teach me to open my mouth, won't it?
You did the work, so I suppose it is only right you reap the greatest reward from it. Take the horns, I'll have them put in a crate for you. Find Belgrom Rockmaul in the Valley of Honor, he'll want to know what you saw and he'll reward you for your hard work.
Be well, [class], and thank you again for everything you've done.
