Exon

Chosen survivors of dying Earth escaped to the nearest habitable exoplanet named Exon but what an irony, Exon's native civilization seems escaped from their only city and home planet without a trace. No sign of struggle or war, they seemed to simply vanished into thin air.

As humanity settled into their new home, they tried to find out why the natives left their planet but in the process a bizarre explosion transformed unlucky ones into ghost-like beings sooner or later. While leaders of humanity tried to hide the problem under a carpet only one person has what it takes to solve the mystery.
