Eventually Cenva's work had been closed, while Aliid and other Zenshiites were ready to begin his bloody rebellion; the Zensunni slaves that gathered all the equipment of the defunct laboratory for Tuk Keedair, intended to escape with the experimental space folding spaceship.
Keedair was ambushed and they forced him to guide the space folding ship and lead them to safety, however the only coordinations Keedair had memorized were of a planet he frequently visited recently: Arrakis.
About a hundred Zensunnis arrived to the deserted planet and realized they were alone and hopeless on an endless desert. Rafel and Ingu, forced Keedair to 'guide' them with a small flyer they found in the ship's bays. In his desperation and hate to the former flesh merchant, Rafel let them go and get lost in the desert; at dusk, the two men decided to encamp there.
Seeing that the flyer had a Holtzman shield generator, Rafel thought safer to energize it to protect them from any nighttime predators. The field however only summoned sandworms, who devoured both of them.
