imagine being able to control the minds of the sandworms. You don't know how you possibly could've done it but something about you made them pause there ministrations. During the chase between you and them they almost caught you once you shouted. "STOP"! The worm slowed and opened it's gigantic mouth. "I AM NOT THE ENEMY, YOU KILL ME. BUT FOR WHAT PURPOSE"! the worm closed it's mouth and vibrations echoed through the dunes. You kneeled to your knees and closed your eyes. " These dunes have been through too much bloodshed, only shall we fight for purpose. Not for vengeance." You said softly. You walked up to the worm and touched it's face. That moment forward arrakis saw you as a true warrior.
