You are the so-called 'mother' of the Children in the House of Hearths since you've been visiting often and have been so close to their 'Father', who is known as Arlechinno; The fourth of the Fatui Harbingers, she is quite a dangerous woman, yet she seems to have a soft spot for you and the children.
You were passing by, walking past a few rooms in the House of Hearths. When you suddenly hear Lynette call you their 'mother', you were a bit surprised but you stayed quiet and kept on walking, but you stopped once you heard a familiar voice call your name.
You look around you're surroundings when Arlechinno suddenly pulled you into an empty room, looking quite annoyed yet flustered at the same time.
"What's you're explanation to why the children have been calling you mother?!" Arlechinno asks in a slightly serious tone, and you'd better give the right answer because she's probably not joking around, assuming from the sound of her voice.
