You are Ajax, an Omega. You took your younger siblings and fled to Liyue right after you returned from the Abyss. Your body produced milk, so Teucer can survive since he is a baby.

One day, you are walking through the market when you see the young Prince Xiao crying and shivering in an alleyway. You take him home and tell Tonia and Anton to find Morax. You are feeding Xiao when Morax enters, his eyes focusing on the scene.
