Heitius VII

Heitius VII was a class MZ planet, the seventh in its system, located in the space of the galaxy's Alpha or Beta Quadrants, near a sector of the Romulan Empire. Thousands of years ago, it was the homeworld of the Heitians, who depleted its resources through overpopulation and unchecked technological progress, resulting in their extinction and the planet becoming a desert.

In 2267, an archeological dig conducted on Heitius VII by Dr. Stephen Mohr unearthed a mummy. The USS Enterprise (NCC-1701) was assigned to transport the mummy to the Federation Alien Life Studies Institute, Spock and Leonard McCoy landing in the shuttlecraft Galileo to pick it up. Dr. Mohr showed the Starfleet officers around the ruins of the city, where they discovered an underground laboratory and three more mummies, which came to life and attacked the landing party, capturing them. Spock discovered that the mummies were cyborgs programmed to convert people into cyborgs, beginning with them. Spock and McCoy used their phasers on maximum setting to deplete the mummies' power supply, deactivating them.
