Per Aspera Ad Astra (Genshin impact)

Roxana is tired. Her head hurts, she hasn't slept the last 48 hours and the paperwork that still piles on her desk seems to mock her incompetence.
"Mademoiselle Roxana, Monsieur Neuvillette request you to come to his office as soon as possible. He says it's very urgent."
She groans. What have her subordinates done this time? Or was it Furina, maybe? No matter, she'll have to fix it all the same. She doesn't remember being promoted to local baby sitter, especially towards people in their thirties, but if it takes some of the weight of their shoulders it's probably worth it. Is it?

Or: Roxana get's thrown into Fontaine without any warning, climbs the corporate ladder at lightning speed, gets haunted by a spirit who, for some reason, is really attached to her, gains immortality and tries to keep the seven nations from going for each others throats via diplomacy and girl bossing.
