The Shasvastii are a lost race. They once flourished as a galactic civilization spread across the entirety of the island universe known to humanity as Messier 82, a starburst galaxy. One hundred million years ago, however, their galaxy collided with Messier 81 and their civilization was ripped apart.
In an effort to save their race, the Shasvastii spewed Embryo Arks out into the dark vastness of space, targeting thousands of galaxies across the Virgo Supercluster in order to maximize their odds of success. One of these Arks crossed a void of twelve million light years before finally alighting in the Milky Way. The local Shasvastii hope that other Arks were also successful in their journeys, but they have no way of knowing for certain.
