Praxxis orbits Barnard's Star, one of the closest stars to Earth at a distance of 5.9 light years. It was one of the first extrasolar planets settled and colonised by mankind, during the Early Interstellar Expansionist Era (2566 - 3239 CE)

Praxxis is small and cold, with a mass roughly 76% that of Earth and an average surface temperature of -49 degrees Celsius. Originally, it was used as a penal colony and supermax security prison, housing extremely dangerous criminals of the former Solar Federation in a highly inhospitable and inescapable environment. Following the adoption of the Chee Doctrine and the eradication of confrontational thoughts through the Human Empire, Praxis was repurposed as a military outpost and shipyard: its small mass and lack of significant atmosphere allows for easy launching of spacecraft, and the Imperial Navy of Man have extensive training facilities on the planet.

Due to Praxis' close proximity to Sol and the Holy Earth, it is considered one of the Human Empire's most important military strongholds and a major component in the Imperial Navy's strategic arsenal. Despite several outspoken threats against humanity's 'uncivilized practices' on the planet from alien envoys, Praxxis is highly valuable and necessary to the mounting war effort, and under no circumstances is implicated in any outlawed or sanctioned activity.
