Alternatively could be the wall of a prison full of Weeaboos

Note that there’s about 4 Billion in the LAVR military alone, let alone the entire faction’s population

Not really. The only ones around are either slaves, pirates or merchants, selling off their rare earthling goods.
There’s also supposedly about 50 humans in the LAVR too.

By most races aside from the Charcadons and Solarians, they’re seen as warmongering savages that strip they’re own city worlds of recources and STILL use religions despite the fact they should’ve moved on by then. Most races in CD are either 100% atheistic or gave up on their religions once science gave them answers. Only very few races like the Fenreeshans and Tryquilleeans use religion nowaday, the Tryquilleeans don’t even believe in their religion but they still use it for guidance and culture

True, but only a few, considering little is known about humanity

Well I’m heavily bound to science and i also can’t use anything that’d drain the ship’s battery in a minute

Light speed travel is used for short journeys but mostly it’s portals, whether by folding space-time to create a wormhole or by using inter-dimensional drives to pass into a form of space where every metre could equate to millions of miles, however that’s only really on Verrinian Republic and Union ships, and the big ones too. There are smaller ships that have achieved it too but cannot mach the speed of the larger ones.

It’s not easy to add things into CD without adept creativity.

1) the reason you don’t see mass robot armies is because of EMPs, which are already in wide use due to the devastating might of some of the strongest faction’s vehicles like the AOW Havoc Walker and Union Advancer, Arch Advancer and Arch Advancer Primes.

2) while humanity did indeed get advanced enough to create super intelligent AI, they never did since creating a treaty to ban the creation of free thinking AI.

3) The Kracknos and Neurox like the Solarions enough to let them in the AOW.

4) there are some robots created for mundane tasks like farming, construction, cleaning, cooking, all that jazz. Some even for the military but aren’t very ccommon due to the aforementioned EMP weaponry widely available. None of the bots look human though.

5) I’m trying my best to leave humanity out of this as much as possible. I hate it when watching a sci-fi thing and either the protagonists are human or all the aliens are gust humans with f**king green skin (lookin’ at you Gomora). I want it to be special when a human appears, to be one of those “HOLY S**T IT’S A HUMAN” sorts of moments. They’re unimaginably rare so making as little ties to them as possible is essential to keeping them special

Water worlds aren’t very creative but are existent. However, Arscalcia, Fenreesha and Wetiece steal that idea. Arscalcia being an earth like world with lots of lakes and oceans, Fenreesha being 95% water on it’s surface and Wetiece being full of huge craters and caverns full of water, a popular hiding spot for Space Pirates.
