Exo III

Exo III was a planet once inhabited by a group of Great Old Ones who left their bodies at some point in the Universe's distant past. Archaeologist Bernice Summerfield explored the planet's tunnels. There were images of them in their bodies in a citadel. The images were carved in living rock millions of years earlier and were identical to older carvings on Veltroch and on other planets, including Earth. (NA: White Darkness)

Around 59,000 BC, the Gubbage Cones' galactic empire encompassed Exo III,when it waqs inhabited by androids. (MA: The Crystal Bucephalus)
