In 166.M40, over one hundred Regiments of the Imperial Guard defended Rebas as it was invaded by the Skullsworn Warband. In the bloody battle that followed, the Skullsworn destroyed eighty-eight of the Guard's Regiments, before the eight surviving Chaos Space Marines all simultaneously became Daemon Princes. In the aftermath of their ascension, nothing remained on Rebas but mountains of skulls.
