The Visitors

The Visitors were the original sapient inhabitants of the planet that later became the Mantle. They possessed advanced technology. Their fate is up to debate, as they left behind little evidence, and no bodies, just Ruins. Several theories have sprung up that tried to explain the lack of bodily remains. Theories such as The Cult of Aleph, which believes that they succeeded in ascending to the stars in the footsteps of their creator Aleph.
