[@Zugzwang] That's actually quite similar to the [s]Space Tiefling[/s] Ra'Voric Empire. They're also really low-key eugenicists who are obsessed with the purity of their race. 

A note about the empires, while they aren't technically racial, the capitals are the homeworlds of each of the council races. Each of the four empires is generally associated with, and primarily populated by, one of the council races. This is especially true with the Ra'Voric, who have managed to lower their non-Voric population by imposing huge taxes on non-Vorics. The Galactic Council is a bit upset by this, but they're still licking their wounds from the War and the Ra'Voric have the largest post-war military since they were neutral right up to the end. No one wants to risk another war over space-racism.
