Proof of Deed
Take Margol's Gigantic Horn to Curator Thorius in Ironforge.
Margol's Gigantic HornDescription
You expect me to believe a story like that? The real horn would have had my broken axe head still lodged into its surface.
Listen, take that obvious fake to Curator Thorius in Ironforge. If he can validate your claim, you will receive a proof of deed. Bring that proof back to me and I'll give you the key to the Searing Gorge.
Get going!
Progress
Why hello there young man/lady. Would you like a tour of the museum?
Completion
What's this?
Oh my, I don't believe it! Do you realize what you've got here, <race>? This is the horn of Margol the Rager! Margol, the bane of every archaeologist that ever set foot in the Searing Gorge.
May I keep it?
