For the sake of the universe’s continued existence, every civilization deemed worthy of venturing into the stars is granted a trial by the gods to determine whether it will survive.
Pass, and your civilization evolves, living as long as the heavens.
Fail, and you are reduced to dust, as if you had never existed.
“Civilizations that draw the biological trial have a pretty high pass rate.”
“Being assimilated doesn’t count as passing, does it? They were assigned to cannon fodder duty.”
“By that logic, the biological trial’s pass rate is the lowest of them all, then?”
“All I can do is wish them luck.”
