During the early years of the Galactic Civil War, the Ssi-ruuvi Imperium raided a number of Imperial outpost worlds along the edge of civilized space, enslaving their Human colonists through a process known as "entechment," as part of a deal struck with Emperor Palpatine, who craved the aliens' technology. One such colony world was B'Knos, which the Ssi-ruuk raided in 0 ABY.
When Emperor Palpatine made contact with the alien invaders called the Ssi-ruuk, he made a deal with them: In exchange for their battle droid technology, the invaders were allowed to attack smaller colonies at the edge of colonized space. The B'Knos mining colony in the Abran asteroid belt was one of these.
The Ssi-ruuk raided the planet B'Knos.
Since the Empire wanted to keep the presence of the Ssi-ruuk a secret, the Imperial Navy released a cover-up story at 35:8:16, which was published through Imperial HoloVision and Galaxywide NewsNets. According to it, the supply ship Ambitious crashed into the mining colony due to interferences of the local star and the mineralogical composition of the asteroids. The captain of the Ambitious, Vin Freen was posthumously awarded for his bravery, since he tried to stop the disaster by destroying his own ship.
Nonetheless, rumors escaped about this and other incidents and spacers whispered about them in the galaxy's cantinas.
