During Muad'Dib's time as Emperor, Scytale appeared as a Face Dancer, who was sent to Arrakis to observe the first Duncan Idaho ghola murder Paul after the death of Chani. However, when the plan failed and the ghola's original Idaho memories emerged, Scytale was killed. His body was spirited back to the Tleilaxu, replicated as a ghola, and his old memories reawakened.
