As of 2149 (a couple years after the end of the Orionite War for National Rejuvenation), five member species are official signatories of the United Federation of Orion’s founding document, the Singapore Treaty. However, most people consider it as eight, separating humanity’s two major sections as well as their two spawn.

These include:

\- Terran Humanity. The founders, the big dogs, and the eldest. Incredibly happy to be here with their gang. From the planet of Earth, although spread throughout the Federation. Lots of genetic diversity due to gene modification, which leads to some interesting results as you’ll see later down the line.

\- the Dilinici. A race of mammals with a thick, inert fur coating. Humanity’s closest companion given they have the most compatible set of communication systems (both using vocal and gestural language). Often compared to Terran Bears, although significantly smaller. Native to Stör!le|le. Very low in population and new to space. Happy to be here with their protectors.

\- the Europans. A race of close-to-fish that mostly use electrical impulses to communicate. Pretty close allies with the Terran Humans due to sharing a home system. Relatively isolationist. Often compared to Terran cookie-cutter sharks. Still has a massive culture shock from uplift, and isn’t quite as happy to be here. Lowkey stressed as fuck but doing their best.

\- the Frinstari. A race of nomadic insectoids native to the Austrickan Transolar Empire with a destroyed homeworld. No close Terran analogue. Mostly fucks with the Federation because they give them free rein over space so long as they follow the laws. Look very closely at the “I Really Wish I Weren’t Here Right Now!” button. 

\- the Zincstili. Another nomadic race, this time much more warlike. Basically space mongol crocodiles. Really fucks with Terran humanity after they put up a stiff resistance to them, and the Austrickans basically forced them together during their occupation of the Orion Arm. Exceedingly willing to go along with the Federation’s bullshit in the name of protecting their pack.

\- Cantoran Humanity. Don’t ask why there’s two of them, they’re magic. Probably gonna blend with Terran Humanity at some point as magic seeps out of Cantora. Contemplative. Is this what the stars are truly like? Is this what they have gazed up at for millennia wondering what if? How many beliefs can this call into question?

\- the Synthetoids. Terran Humanity’s robot friends who they built because they were lonely before everyone else showed up. Generally act very similar to humans with some quirks. Does not like the irrationality of the Organic Species but puts up with it because they like them.

\- the Therians. A catch-all term for uplifted Terran species and hybrids with humanity. Same situation as the Synthetoids. Basically anything between an outright anthropomorphic animal and a catgirl. “Every day, we stray further from god.”

A dysfunctional and happy family
