District Four.
Returning to their peaceful and comfortable home after several weeks in the busy Orion City felt so good.
The tranquility of this house allowed Iris to think clearly once again and plan the new direction of her life she would take.
Initially, her sole plan after her rebirth was to seek revenge on her killer. But now, her goal has shifted; she wants to help Eric regain an everyday life without relying on a magic shield to conceal his damaged body.
Iris is thankful because when she shared her plan to bring Eric to this country with Xavier, he supported it. He even offered his island for Eric to stay.
The island is in District Four, just an hour away by boat from their house. Because the distance was not too far, she could visit him by boat every time she wanted—teleporting might not be her choice to go there because it could make Eric suspicious of her.
