Ten thousand years ago, when Planetary Emperor Pythor was still the leader of the weak human race, this place was a barren desert, one of the sites where acid rain was abundant and therefore a land of death that no one cared about.
But when the Overlord first contacted him and told him how to build a space portal, he gathered a thousand experts specialized in weapons manufacturing and brought them here to build the portal in complete secrecy, the portal he used to go to the Pit of Destruction planet and bring the race upgrade device, the portal he later used to surprise his enemies and struck them from behind, the portal he used to transform himself from a petty leader who was destined to die in unending war, to a Planetary Emperor who was almost worthy of the title of multi-planetary emperor!
