Spaceship (The Curse of the Black Spot)

The Unnamed Spaceship was a spaceship which had become crashed in the same place as the Fancy, but in a different dimension.

Features
The ship had a least 2 living crew members, as well as an artificial doctor. There was a medical station where the doctor could treat patients, keeping them alive and unconscious even with seemingly fatal conditions. (DW: The Curse of the Black Spot)

History
The spaceship accidentally became trapped in the same space as the Fancy, with any reflective surfaces acting as portals to the other dimension. Though it was able to give out a distress signal, a disease somehow got passed from Earth to the crew, killing them. The ship's artificial doctor then began taking injured crew from the Fancy and transported them to the spaceship for treatment, becoming known as "the Siren".

The Eleventh Doctor came to investigate the distress signal, but landed on the Fancy instead. Despite his efforts, the Siren continue to take the crew until the Doctor decided to go with it. Once on the spaceship, he realised the truth and released the crew of the Fancy. They then took the spaceship for themselves, setting off for the Dog Star. (DW: The Curse of the Black Spot)
