After these people were safe, they were unwilling to remain hiding underground.
They wanted to understand what exactly had happened? Why did such a catastrophe occur?
Even if the planet was destroyed, and the stars vanished, why couldn't the Empire be contacted?
So they started researching!
Among these people, there were powerful Transcendents and advanced mechanical equipment, with many means to "observe" what had happened back then.
Soon, someone discovered part of the "truth".
However, those who discovered the truth, for some reason, without exception, committed suicide shortly thereafter!
Their research records only contained gibberish, along with some bloody warnings.
Before they died, they left warnings for the survivors not to attempt to research the truth further.
Otherwise! Everyone would die!
However, how could the survivors resign themselves?
They continued their research, and thus met their demise one after another.
