Morbius once aquired a stellar manipulator for his plans of universal dominance. The Eighth Doctor stole the control device to foil Morbius' plans. (AUDIO: The Vengeance of Morbius)

Morbius' stellar manipulator was built to follow its control device. It followed the Doctor to the planet Orbis, where it disrupted the gravity of the planet and tore it apart. (AUDIO: Orbis)

The Eight Legs then took over this stellar manipulator, and sent it towards Earth, where it became a second sun for the planet. (AUDIO: The Eight Truths) The Eight Legs used the stellar manipulator to power their psychic powers enough to spread their influence across the universe. The Eighth Doctor stopped this plan, then hid the manipulator away in a "dark corner of the universe". (AUDIO: Worldwide Web)
