Marked Globe Edit
The Gaians travel to Earth, their ancestral home, in order to exterminate an existing Super-volcano that was close to erupting, creating another mass extinction event. Following this, the Gaians began stripping various places of the planet for resources.
Solans descend from Homo Magnus over 70,000 years ago. They went through a range of adaptations through living on their new home planet away from that of earth.
