Over a hundred thousand years ago, the invasion of the Dark Matter Sea brought human civilization to the brink of annihilation.
At that time, humanity had only two paths before it.
Since surrender was impossible, they could only flee or fight to the death.
Many humans left this star system for distant, dangerous places.
Perhaps they found a new paradise; perhaps they vanished without a sound into the vast universe.
For certain reasons, the vast majority of humans could not leave their homeland. In the end, led by that god, they perished together with the Dark Matter Sea.
