Le Verrier

The Le Verrier was a space station in the 38th century.

History
Professor Gagan Rassmussen invented the Morpheus pod on the space station in the 38th century. Sometime after this event, the sleep dust on the eyes of the Morpheus patients created the Sandmen, which completely enveloped the crew and transformed them into creatures of their own kind. Rassmussen hid in a Morpheus pod, and he was later found by the Twelfth Doctor, Clara Oswald and a rescue crew sent to relieve the crew. (TV: Sleep No More)
