See the funny thing is, all of the characters I'm using in this are at least a year old (as in I've had them for a year) and this rp is just an alternate timeline of their original story. It won't really interfere in a bad way, but they each actually have a fully completed backstory and an overarching backstory of the whole place that hasn't even been mentioned in the rp.
Funny tidbit about that, I didn't say anything about it because I thought it was fun to run with, but in the original story, it isn't a dystopian future, but a lightly steampunk-style, industrial themed, dystopian past. That's why in all of their character pictures, the robotic parts look fierily clunky and primitive instead of sleek and advanced. And though it wasn't really relevant, I was sort of thinking about it when Fem is thinking to herself about "how much the tech has advanced." In her original story, it's all just gears and pistons and tiny hydraulics.
