Xethar: The Thing of the 'Past'

Planet Xethar was created after the mass Giant Wipeout Death of the old planet Earth and the Human race. During the year 2020, the human body was infected by a disease named Reaco. Reaco was a cell that made the human fall into a 'zombified' state and eventually dies along with Earth.
Three hundred years later and planet Xethar was a memory of the past to most other planets alike to planet Saturxena. Saturxena was a planet based solely around 'magic' as an energy source. Most planets don't have the advanced technology as Saturxena does. Mythical Engine Ships are used by Dark Mages that habit the planet. Out on training the new recruits one named Lucious ends up accidentally crashing his ship into Xethar the 'dead' planet that's un-habitual.
Lucious regains his consciousness and learns that he needs to rebuild his ship to fly back to his own planet. After a quick scout of the planet, he learns his thoughts of the 'dead' planet has been quite vibrant with all kinds of living organisms.
Surviving in the harsh reality of Xethar's unnatural painful living conditions Lucious finds a bunch of different companions to help him survive while fixing his ship.
