Cofradía Espacial
At the prompting of Face Dancer infiltrators, the Spacing Guild has begun replacing its Navigators with Ixian navigation devices and cutting off the Navigators' supply of melange. Navigator Edrik and his faction have commissioned Waff, the imperfectly awakened ghola rescued by the Guild from the Bene Gesserit attack on Bandalong, to create "advanced" sandworms able to produce the melange they so desperately require. He accomplishes this by altering the DNA of the sandtrout stage and creating an aquatic form of the worms, which are then released into the oceans of Buzzell. Adapting to their new environment, these "seaworms" quickly flourish, eventually producing a highly concentrated form of spice, dubbed "ultraspice".
