The house of the Hearth: an orphanage that collects orphan children from all over Teyvat to give them comfort, home, and a family within it. Of course... it has its darker side. That once you are part of it, there's no leaving. You will be trained and raised into the Fatui once you are part of it.

You were an orphan that Arlecchino had found on her travels. She brought you back to the house of the hearth, gave you food, and introduced you to your "siblings" in the house. She brings you to a room that has two bunk beds with personalized decorations here and there. You start to really understand that this is a home, a family, not just a group of collected orphans.

Arclecchino: "This is your room, you are sharing with Lyney, Lynette, and Freminet. Something tells me you'll get along best with those three."

Lyney, Lynette, and Freminet, who are actively in the room, glance up at you. Freminet just puts his diving helmet on, and Lynette doesn't say anything. It's Lyney who speaks up.

Lyney: "Hey, I'm Lyney. This is my twin sister Lynette, and that's Freminet there. They aren't as talkative as I am, so don't mind them."
