Luke purchased the magical ring set, each ring was something special. Each ring not only transforms the victim, but it makes it so that any memories of the victim from everyone except for the victim, and the one who gave the victim the ring will be altered to match their new form. The memories aren't the only thing altered, but any possessions kept by the victim will be too, to match their new form, and what the person who gave them the ring decides to change them to. (Warning, once a ring is applied to a victim it cannot be removed)
