Thallo and Attempted Mass Genocide[]
Thalidei was the location of the failed Kwisatz Haderach experiment initiated by the Tleilaxu Masters during the early part of the reign of Emperor Paul Atreides. Their super-being clone construct Thallo ended up trying to commit mass genocide and suicide, by flooding Thalidei with a deadly nerve gas. He failed as he was killed before doing so by the visiting Marie Fenring, who was with her parents, as they were observing the Tlelaxu's twisting techniques.
