Actually im just gonna keep going if you don't mind this is really cool
Where do these rebels get their supplies and stuff i was wondering... like, are they fully self-sufficient in regards to like farming and agriculture do they trade with some other community/nation perhaps? :0 you dont need to answer or think of all of these of course akdbsjdbdb worldbuilding serves plot and not all of everything would show up depending on where the story goes
And also—do the rebels have some sort of goverment system? Have they been around for long enough that they need a stabilished way of replacing their leader(s) once they die?
OH and who decides who goes into the mechas. At the kingdom too. Is it voluntary? Is it forced, like mandatory military service? Do they "source" their pilots from some kind of institution, like a shady lab or maybe an outstanding academy I have no idea. Is that method of aquiring pilots too different from the rebels to the kingdom? :0
Oh and do they use the gregorian calendar (365 days 12 months leap years every now and then year zero is the birth of christ etc) RANDOM AND LIKELY INCONSEQUENTIAL but um. I think calendars are neat.
Ok im done u_u be selective as your heart desires no pressure
Where do rebels get their supplies?
Mostly trade with other nations who remain neutral in the conflict, but there are sometimes supply raids on state supply depots, or hijacking supply trains etc. They have farming of both animals and crops, but as for other supplies they're all either stolen or traded with other nations.
Do the rebels have a government system?
Their government system is very rudimentary, with a simple sort of "leader, second in command, third in command and then everyone else" kind of system. I haven't yet decided who they want to put in charge once they overthrow the state, but it'd probably be whoever leads the rebellion? The rebellion's leader, though, is somewhat of a figurehead, as the system of making decisions is more democratic and the title of leader is more of a military title of who's in charge. They haven't been around long enough for them to need to replace a leader, but it's assumed that the second in command would take up the position.
Who decides who pilots the mechs?
For the state, it's involuntary. The mechs have a form of neural connectivity that allows them to be piloted, and some people have innately higher connectivity - they still don't know what causes this, but they're pouring a lot of money* into figuring it out. Generally pilots are taken by the military, as people over the age of 13 have their connectivity tested mandatorily every few years. Carrion (the main character) was taken at age 15.
They're shuttled to the capital's military base by people carrier bus kind of things. People within the state generally view becoming a pilot as a privelige, as glorious because of the propaganda that gets put out. This leads to many pilots being entirely unprepared for the intensity of the training and either dying or getting kicked out.
In terms of the rebels, they have the same problem of connectivity, but whether or not you pilot the mech is voluntary. People who have high connectivity (testing is still mandatory, they don't really have the freedom to be missing pilots) are allowed to choose whether they want to be a pilot or not, but most people agree to it because they understand what they're fighting for. Transport to the military bases is a lot less dystopian as they're just like, driven in a car or bus etc. or any other public transport (their public transport system is rudimentary at best)
What calendar do they use?
They use a version of the gregorian calendar same months/year naming as ours except they're in the year 10,026 - see Kurzgesagt's video on the "human era" calendar, because I think it's a really cool idea. It essentially places the start of human civilisation 8000 years before the real world "common era" (BC/AD, year 0), and uses that as the year 0 instead of the birth of christ. The story takes place starting in 10,006 (2006).
*the entire world uses the same money system in this story for ease of writing it, this being a non descript "credit" system. As for languages, there's several languages spoken throughout the world (less than the real world though, on account of the state taking over the vast majority of the world) but all of the languages spoken are real world languages. I've yet to decide which are used, but the state speaks English (because it's the only language i speak T-T)
