In the Legends of Dune prequel trilogy (2002–2004) by Brian Herbert and Anderson, unappreciated scientist Norma Cenva creates the Holtzman engine, which allows a ship to fold space, traveling great distances instantaneously. Her future husband, entrepreneur Aurelius Venport, begins mass-producing the ships which are eventually known as heighliners. The technique proves to be unsafe, however, as one in ten flights ends in the ship's destruction due to navigational difficulties. Desperate for a solution, Norma consumes increasing amounts of melange to improve her thinking and concentration. Full immersion in a tank of spice gas deforms her body, but ultimately bestows on her the prescient ability to plot a safe path for a heighliner through foldspace. As the first Navigator, Norma begins a training program to produce enough Navigators to pilot a fleet of heighliners. Over 80 years later, she puts the creation of the Spacing Guild in motion through her descendant, Josef Venport.
