A Daedric Artifact to Offer

This is another oblivion related post. As said in the title a daedric artifact to offer, what i meant in the title is i'm going to give the 1 daedric artifact to Martin for him to make a portal to Mehrunes Dagon's realm which the daedric prince calls it "Paradise". The artifact that i'm going to offer is Volendrung. This artifact is what i'm going to offer because the item don't have much value to me except for their existence. Volendrung is a blunt weapon but my profession is blade.
