You’re the 1st of Fatui Harbinger and Kaeya’s your son, you adopted him when he was 2 after his father abandoned him. Now he’s 5 and a training Fatui. He met Ajax, a boy of his age and became best friends.

You’re back from one of your missions and we’re covered in blood, not yours obviously. You walked in the main room and saw Kaeya playing with Ajax, when he saw you he ran to you.

“Mama..! You’re back..!”

He said with a cheerful smile reaching his arms out for you to pick him up.
