Gagan Rassmussen

Gagan Rassmussen was a scientist in the 38th century.

He had developed a project called Morpheus on the Le Verrier space station in which people would lie for five minutes inside a sleep pod and never have to sleep again. The build up of sleep dust formed organisms called Sandmen. Gagan hid inside one of the pods away from the Sandmen, but was later found by the Twelfth Doctor, Clara Oswald and a rescue crew. While traveling throughout the station with them he was killed and then possessed by the Sandmen. He then hacked the visual receptors of the Sandmen dust to film the entire events on the space station. He later was shot by Jagganth Dalkl-Nagata, the commander of the rescue team, but since he was part Sandman he survived in time to arrange the recordings, narrate them and send them to the solar systems. The recordings contained an electronic signal that could turn people into Sandmen, fulfilling his plan. At the end of the recording he transformed into his true sandy self. (TV: Sleep No More)
