[@RickyG85]Few questions if you don't mind: 
- What is the age of adulthood? Life expectancy of normal people during this era? 
- Does hydroponic/mushroom farming exist for large settlements? 
- How human-desired are they? Like given a mortally wounded Giant and a mortally wounded human side by side, what would a Giant go for?
- Also tech level? Like 1945 for the Outside World as was portrayed in AoT?

I'll try to whip something up soon.

Those are some good questions! In order:
-It varies; Undergrounders try to protect their youths at least until age 15 and the more well off Mole colonies can manage the mid 80's for people who live safer lives. Meanwhile Rat's in their more survival focused groups could expect a kid to start pitching in as soon as they're old enough to hold a knife or lift something heavier than a stool,  and might look at you like you just said "I'm immortal" if you tell them you're 45.
-Yes.
-Pretty strongly, [i]but[/i], They'll go after whichever is closer or caught Their attention first.
-Civilization as we know it fell in 2025, so the disparity of tech level between human communities can also be radical, but the ruined state of the surface also makes it much less reliable, up there.

Does that sufficiently answer your questions?
