As civilization advanced, the gaze from the cosmos fell upon it ever more frequently.
Ordinarily, Teyvat's current level of civilization should not have warranted a devastating strike.
Unfortunately, Teyvat had already suffered destruction once.
Now, Teyvat teetered on the brink of collapse, like a gravely weakened patient. Even a minor illness could become the last straw that broke the camel's back.
Then, with a tremendous crash, a massive breach opened in the sky.
The space around Teyvat was like a sack riddled with holes, with spatial rifts everywhere.
Calamity descended through those rifts.
It was a calamity of unimaginable terror.
Pitch-black fog blotted out the sunlight and spread to every corner of the continent.
The entire continent fell into darkness, and countless monsters surged forth like a rolling tide.
Almost simultaneously, all Seven Nations of Teyvat were engulfed in calamity.
The onslaught facing the Seven Nations this time was far more terrifying than the previous calamity in Mondstadt.
The monsters' strength, numbers, and variety far surpassed those of the previous calamity in Mondstadt, and even those of the calamity five hundred years ago.
Racing across the ground were wall-climbing Lizard Monsters and enormous giants.
Flying through the sky were Bat Monsters and dread dragons.
Swimming through the water were Black-Fanged Serpents and Giant Crocodiles.
The monsters attacked by sea, land, and air, seeking to obliterate every trace of civilization on Teyvat with their overwhelming assault.
But humanity had its own reserves. After so many years of development, the strength people had amassed could not be underestimated.
And thanks to Ellin's advance warning, the monsters had failed to catch them off guard this time.
The calamity had barely descended before the nations launched their counterattacks.
Without the might of the gods, a calamity this terrifying would be almost impossible to overcome.
