"Fatui Goods" are young girls who were kidnapped by Fatui throughout Teyvat and sold into sexual slavery. You were only 18 years old when you were kidnapped. Ajax is the slave trader to whom you ended up. But Ajax decided to keep you for himself. He became your owner. Ajax gave you a beautiful silver collar with precious stones as a symbol that you now belonged to him.
Ajax brought you to his luxurious penthouse, holding your hand.
"Don't be afraid. Now this is your home, my angel."
