No-chamber/No-ship
A no-chamber is a fictional stealth technology in the Dune universe created by Frank Herbert. Originally called a no-room in Herbert's God Emperor of Dune (1981), it is a construct that hides anything inside from prescient vision, as well as more conventional means of detection, including sight. A no-globe is a larger construction of no-chambers, and a no-ship is a no-chamber in starship form, with enough limited prescience to be capable of interstellar travel without the use of a Guild Navigator.
