Humanity fell and rose back up.
The humans teamed up with sentient tech to overcome the world's calamities. Peace came, however, not all could be fixed.
The old sentient technologies were irreparable after the devastation due to the lack of resources.
Time was broken.
Ocean structures collapsed.
All technological advances had to be recreated.
Humanity was the sole survivor.
Now, in a post dystopian era, stabilization thrives on technology we would not even dream of. New sentient beings were created and the world existed in harmony.
