79B Aickman Road

The flat at 79B Aickman Road was in reality a timeship belonging to the Silence. It had come to Earth before 2010.

Characteristics
From outside, 79B was somewhat like an inverted, curved pyramid, with four legs/landing struts. It had a perception filter to blend in with its surroundings and convince anyone who looked upon it that it had always been there. When it took on the appearance of the non-existent upper floor of 79B Aickman Road, even Craig Owens, who lived in the house, accepted the reality of a second storey. The Eleventh Doctor, after first seeing the ship, called it "someone's attempt to build a TARDIS".

The ship drew some kind of power from its pilots, who steered the ship with their thoughts. Humans were incompatible; the energy-drawing process invariably resulted in the candidate's death. Time lords were too much for the system and would overload it, enough to blow up the solar system.

The ship had a holographic autopilot which activated when damaged. The autopilot searched for people to power the ship, using the building's intercom to communicate with people outside and changing its appearance to lure them in. All of the holograms seemed to lure the victims by saying that they needed help. (DW: The Lodger)

History
Number 79B, Aickman Road was a timeship that had crash-landed on Earth some time before 2010], after [[River Song killed all the Silents in it at the end of Day of the Moon. The ship hid itself by pretending to be the upper story of 79 Aickman Road over a flat occupied by Craig Owens.

The ship's autopilot attempted to relaunch the ship using humans as pilots, specifically selecting humans who wanted to escape or explore. However, the mind of a human was too weak to launch the ship and the people selected by the autopilot were killed. This created a pattern of decay on the ceiling below, much like rot in appearance. The autopilot's attempt to launch the ship with humans also caused a time loop to form briefly, almost resulting in the TARDIS and Amy being thrown into the Time Vortex.

The Auto Pilot attempted to use the Doctor's mind to launch the ship, but the Doctor claimed that his mind would be too much for the ship. Craig Owens shut down the ship because he didn't want to escape or explore; he wanted to stay right where he was. The ship imploded when the emergency shutdown was activated by Craig.
