Carbon Costume

In Dead by Daylight, Charlotte and Victor Deshayes were conjoined twins forced into hiding in 17th century France. After their mother was burned at the stake, they were captured and indoctrinated by a cult. They set fire to the temple they were imprisoned in, only for Victor to be killed in the escape. Heartbroken, Charlotte wasted away, until the Entity offered a way to restore the siblings to each other.
