About
100 years since the extinction of humanity.
Earth has become the universe's prime candidate for tourism.
On the planet Nea, far from Earth, advanced space civilization has made interplanetary travel and the investigation/development of uncharted planets commonplace.
Noval Corp, a space enterprise specializing in planetary development, environmental surveys, and tourism development.
Noticing the lush nature and the cultural heritage left behind by humans, Noval Corp has begun an investigation to see if Earth can be developed as a new resort planet.
Dispatched to Earth as an investigator is Guest.
