Celestial Orb

The Celestial Orb is a ruby the size of a baseball, carved with symbols that Professor Cosmo Dinkley was able to interpret as a map to the Temple of Sirius, a site that was built by ancient alien astronauts. The Orb was found in the booby-trapped Cave of Death in the aptly-named Valley of the Zombies.
