Morax. For the time being, let's call him Morax.
His former name had long since become an unknowable part of history. His body had shattered and scattered across every inch of Teyvat; his blood and flesh had flowed into every river in Teyvat. He raised his hands and pieced the shattered planet back together, allowing his very existence to be erased...
He fell into a warm ocean.
[Beep. Host has awakened. Please begin your role-playing task.]
Morax opened his eyes and saw a glowing screen floating before him, its text being read aloud at the same time.
[Role-playing task: Play the role of Morax]
Morax lowered his head, revealing a rare hint of confusion.
Play the role of... himself?
After many twists and turns, he finally figured out that this seemed to be another parallel world where Teyvat had not been destroyed. Faced with the System's role-playing task, Morax, having lost all his power, had no choice but to slowly restore his energy by playing another version of himself.
But...
"Why am I on the moon?"

During the Rite of Descension, the Geo Archon was assassinated. At the same time, a huge hole was punched into the sky above Teyvat.
The terrifying hole soon repaired itself, but a logically consistent rumor gradually spread throughout Teyvat:
Rex Lapis, who had returned to the heavens, could not bear to leave Liyue and Teyvat behind, and had once again taken the form of countless incarnations to walk the earth.
"And left behind countless beautiful legends!" With a fan opening and closing in his hand, Tian Tie Zui ended the story with these words.
"Are you trying to say he got involved with a lot of people?" Paimon stamped her foot.
"Hey! When it comes to Rex Lapis, how can you call that getting involved?! Brother Zhongli, tell me, isn't that right?"
"...By common reasoning, that is not incorrect."
* Probably an all-Morax pairing.
* A huge amount of original worldbuilding.
* Seriously, a huge amount of original worldbuilding. Please don't worry too much if the logic doesn't add up.
