The Argalian Empire ignored the hails of Human ships who happened to cross the path of their vessels, but always largely remained neutral, keeping their distance. In the last thirty years though, they seem to have opened up, and the reason for this long period of silence appears to be that their society was deeply xenophobic. Once the floodgates of communication were broken down though, a number of Argalian immigrants made their way into Human space. These immigrants proved to be quite the xenophiles, which seemed quite contrary to the Empire’s official stance on Humanity.
Other than their appearance, not much else is known about them. The Argalians are secretive about their society, rituals, and technology.
