Artifact: King Tut’s Scabbard
Occultists are amazingly predictable. All you have to say is something like “King Tut was buried with a dagger made from meteoric iron” and suddenly every member of the magical community is suddenly contemplating how to ‘liberate’ the item in question. Not all would fight for it, but some would; and some would even murder for the right to wield King Tut’s Dagger. And not a man jack of ‘em would give more than a couple of looks at the scabbard.
