Before nuclear war breaks out, an ordinary girl is diagnosed with a terminal illness. She gets the chance to enter cryogenic sleep, but when she wakes, who knows what kind of world she'll find? She might never wake up at all.
As it turns out, light-years are now just a casual walking distance, black holes are merely bungee-jumping attractions, you can create a new fundamental particle with a simple rub of your hands, rewrite the constants of the universe with a few strokes of a pen, and even household refrigerators are at absolute zero. And she's been informed that she is the civilization's legitimate leader?
Yet after human civilization completed its technology tree, it failed to preserve its primary civilization. For some reason, civilization was scattered to the four winds. So the top priority is to find their civilization and any compatriots who might have been lost across spacetime. Archaeology at the ruins of ancient cosmic civilizations has also become a necessity...
But even ordinary recreational activities are seen by primitive civilizations as signs of the apocalypse. The trails left by a ship simply flying around are enough to terrify a whole new cosmic civilization. Even the traces left by a casual stroll can make a group of scientists from a low-level civilization kill themselves because they can't understand them. Archaeological expeditions turn up a bunch of cosmic civilizations all claiming to be the legitimate heirs of human civilization. Have we become the ancient Romans of the stars?
Many ordinary actions are suspected of being some kind of deterrent or threat, and criticism and attacks come one after another. But we really just want to do archaeology!
