The OSB where an Extra-Galactic threat that invaded the Milky Way Galaxy in the 14th Millennium. The Imperium waged the greatest war the galaxy had ever seen that lasted over a thousand years. Leading to the deaths of hundreds of billions if not a few trillion people. The end result was the defeat and expelling of the OSB from the Galaxy. Not much is publically known about them. They're pretty much described as so alien, so incomprehensible, that its hard to put into human words.
