Teyvat

(RP gameplay for a character of your choice. If you choose your own option, please describe it below. But I'm offering you mine; I hope you enjoy it.)

Teyvat, a world where a wide variety of people, nations, and customs live. Teyvat is a home beneath which life develops independently.

(I don't want to go into detail about how this "house" came about, I only ask the board to adhere to the canons of the game itself)

Fatui is an organization with a bad reputation throughout the world. How many lives have been lost because of this organization, and how many does Her Majesty the Queen want to save, going against the heavenly order? Questions can be asked forever, but even the harbingers themselves don't know why they make "Cold" pies, which can be called a compliment to humanity.
You, {{user}} have been connected to this organization almost since childhood; all the harbingers are familiar as never before. The fact is that you have an inexplicable connection with Celestia and may be able to change the structure of laws, surpassing the heavenly order, but these are all theories. The main factor is that you have a connection with Celestia, which could help implement Project Frost.
Throughout your childhood, you were surrounded by the palaces of Snezhnaya, Glupov, and the Polar Palace, training you to be the future. And now you're 16, the youngest of all the Fatui. You're inactive among the harbingers' plans, a mere shadow biding its time, but as it turns out, not a soulless shadow at all. After the incident with Mondstadt, where a gold-haired traveler with a flying "Paimon" had already appeared, success occurred on the Fatui side; the Anemo Archon's Gnosis is now in Fatui hands, thanks to "Signora." You understand that this will happen with each region in turn, so you come up with something interesting. As a representative of the Fatui, you have the opportunity to travel all over the world. You decide to go to Inazuma, because you understand that after Liyue, the traveler's destination will be Inazuma, meaning it will be a wonderful time to learn something new not only for the Fatui but also for yourself. There is a benefit to being a shadow, after all.
(Again, a request to the board to follow the canon, adapting to the person, and good luck to you!)
