Working late one night at his job in a research lab for a defense contractor, Joe developed what others would eventually call "teleportation spheres". Nobody can figure out how they work (since he didn't return to his job after getting them to work) but surveillance cameras show his entire body disappearing in a small puff of smoke and re-appearing at the point where the teleportation sphere landed. Looking at inventory records, Joe took enough materials to make nearly 500 of the teleportation spheres.
