The Federation is a neutral, highly militaristic, dystopian, oligarchic multi-planet nation with one of the biggest militaries in the system. Civilian life in the Federation is horrendous and quite a pain due to the rules, laws, and policies put in place by the government.
64% of the total Federation budget is put into the military, the other 36% is put into civilians. This is much, much more than any other nation.
The Federation is mostly made up of humans, there is the occasional rare non-human, however, they are usually discriminated and harassed.
The Federation, after discovering intelligent alien life, was too busy to truly contact them, for there was an ongoing insurgency which threatened the livelihoods of the people. So, they made a few laws and policies and told the corporations to make first contact and do whatever they want, as long as it was legally possible.
The Federation constantly deals with insurgencies, insurrections, and rebel groups appearing on their own planets. This means the military is almost always active, squashing the “bugs” that were these rebel groups. Said military is also deployed to protests to discourage any more unruly behavior.
The Federation has not gotten into any conflicts with non-human beings as of now, not including criminal mercenaries hired by said rebel groups.
