Located in the Pergitor system, in a close orbit around the sun, Onadax is a tedious place to live. It was once a lush, tropical garden of a world, and it held a rich cache of rare and exotic minerals. The original settlers were employees of Sparra Inc. who came to Onadax to mine the minerals. The mining operations took massive volumes of material out of the planet's crust until intense deep-bore mining by Sparra Inc. resulted in a volcanic eruption that slowly destroyed the atmosphere. Following this cataclysm, Sparra Inc. abandoned the planet, with the mining outposts being swallowed by the lava pits that formed around the mine shafts. As the atmosphere was slowly poisoned, the plant life began to die, and soon after that, the animals began to die off. A few years is all it took for all life on the planet to be extinguished.

As Onadax's sister planet Pergitor passed by, its orbit around the sun having decayed, Pergitor's gravity pulled some of the atmosphere away from Onadax. The process has repeated for many years with each close call stripping Onadax's atmosphere until its last vestiges disappeared, along with the gases expelled from Onadax's core following volcanic eruptions.

After ages of being uninhabited, because of high temperatures and a non-existent atmosphere, the scum of the galaxy found a home on Onadax, where there was nobody else to bother them. But after some time the situation changed, as governments took control of more and more planets, forcing the criminals to seek a protector. They found it in a group of pirates who were said to be driven by the force and studying the lore of a dark being. Rumours continue that this abandoned planet is used as a base for training recruits to survive even in the harshest conditions.
