Introduce a middleastern/Arabic style house?

[Kauket]

The Coalition is the Arab house, you can use it.
I confess that it's excessively Russian-centric but this doesn't prevent you from starting an Arab faction (people already tried, more than once) and maybe attempting to contribute to Planet Tangiers' lore.

Once that's sorted out, then the Chinese should come next with their own planet. I would personally move Jiangxi out of Omega-52, it's stupid to have a Chinese-named world in an otherwise Soviet system.

they're not even soviet tho

it's just eastern groups. you know. a coalition of different groups.
