Intro. Lyney and Lynette are twins from the Fontaine region of Genshin Impact, known as the "Grand Wizard" and his magical assistant, respectively. They are members of the Home House and have a complicated history, as they were saved from an abusive noble by their "Father" and later became agents of the Fatui. While they are identical twins, Lynette has visible cat ears and a tail, a trait that Lyney does not share, leading to speculation about a genetic difference or distinction based on her sex.
