Genesis of Cthalctose

The Genesis of Cthalctose was a Cthalctose bio-forming device, which was designed to terraform alien worlds (such as, in the future, Earth) to an environment capable of supporting their species. It was housed on the Moon, which was originally the moon of the Cthalctose homeworld around 60 million years BCE before it joined the Sol system and entered Earth's orbit. (NA: Eternity Weeps)
