The Galactic Purge is the name given to the extinction wide event the Alethians attempted to carry out as part of their plan of purifying the galaxy of all lesser lifeforms. Numerous undocumented species, planets, and other lifeforms were wiped clean from the galaxy. It wasn’t until the intervention of the Thorions did the Alethians finally abandon this plan and agree to sign a peace treaty. The number of dead from the Galactic Purge is unknown as the Alethians did not keep active records of the species they eradicated, nor did they consider the now barren and dead worlds even noteworthy in their archives. As such it is near impossible, at a glance, to know what planets were always barren and devoid of life, and which ones were stripped of life by the Alethians.
