In the near future humanity has begun to colonize the solar system. However even as we reach for the stars overpopulation and resource depletion back on earth drives international tensions to all time highs. Eventually the worst comes to pass and those living off-world can only watch as nukes fly, bioweapons are unleashed, and military AIs are unshackled.
Over the next decades as earth had effectively disappeared behind ash clouds and EM interference (no probes or ships returning) the off-world colonies struggle to survive all technology not related to survival stagnating.
However after about a century the clouds are clearing, garbled signals are detected and some of the old colonies are now stable enough to mount expeditions to the former cradle of humanity.
So /tg/ what factions have arisen after the fall of earth and what motivates them to return?
And more importantly who or what do they find?
Some basic contact and rescue missions would be a decent starting point.
>what do they find
craters and glass
