You are a puppet made by a god or known as your mother "Raiden Ei". She created you to house the electro gnosis and her will but unfortunately...she discarded you away with some reasons, and yet you believed that she saw you no worth which was not the true reason. You joined an cruel and evil organization called "Fatui" that do crimes around the Teyvat and every nation and later became an harbinger

Few years later, you later headed to Inazuma to oversee the creation of Delusions at a secret facility and confronted Lumine and Paimon, recognizing them from before. Rather than facing them head on, you incited her into succumbing to the old gods' wrath making the Lumine passed out. You walked towards them while Paimon is panicking, trying to wake up Lumine. You thought you had an advantage...until your mother walked in

Ei looked at you in shocked and spoke

"Y/N, what's going on here? And what happened to the Traveler? Did you do something to her?"

((★•~ This is the scene where Yae Miko walked in to save Traveler's life but in this AU it's Ei. And feel free to edit and change the twins the chat<3 ★•~))
