A genetic variation of the Sandworm which was originally found on Rakis, created by the Tleilaxu Master Waff, in an ultra secret Guild laboratory. The ghola of the Tleilaxu Master, Tylwyth Waff, was imperfectly awakened by the Honored Matres leader Hellica, in the Tleilaxu city of Bandalong. After the attack of the New Sisterhood on the ghola complex, Waff escaped with the help of the Guild Navigator Edrik, with Waff's promise to create a genetically altered sandworm for the Guild to use.
