An anomaly!
A fate of calamity and doom, in a world of frost and snow.
An outsider from another world unknowingly changes the entire continent of Teyvat.
"Adepti, monsters, mortals?" Raiden Ei asked curiously.
"Your knowledge doesn't belong to this world. You are the fifth Descender to arrive in Teyvat, Bai Wuyang!" Nahida said, looking at him.
"Would you like to make a pact with me?" Zhongli asked.
The Abyss!
A girl in a magnificent gown sat high upon the throne. She was the princess of the Abyss. A nonhuman herald watched the white-clad figure with a sword and an umbrella in his hand.
"From this day on, his words are as my own."
Heh... Heavenly Principles, the worst mistake you ever made was sending him to my side. As for my brother...
A shadow crossed her eyes. She called out to the white-clad boy, "Brother~"
And so the Abyss welcomed another prince.
