New Memphis

New Memphis was an Earth colony, established prior to 2479 (most probably in the middle of 24th century). It was well known for its large spaceport, known as Elvis the King Spaceport and its largest settlement, New Memphis.

Astronomical data
New Memphis was barren and largely uninhabited. All of the cities were located on one island and 98% of the planet was undeveloped. Rain was common on the planet, but it was unknown if this was because of the pollution of New Mephis City or for natural reasons. (NSA: Judgement of the Judoon)

History
Before humanity arrived, New Memphis was an uninhabited planetoid of little interest to anyone. However, the government of Earth evinced interest in the planetoid because it was close to a major hyperspace nexus point. A refuelling station was established to assist the traffic crossing that point, coming from at least a hundred different star systems.

Over the course of a hundred years, the refuelling station became more permanent and was named the Elvis the King Spaceport. Soon, a permanent population begun to establish itself and the city-state of New Memphis was established outside of the spaceport. The spaceport had ten terminals at full working capacity and a further two shut down pending further notice. In 2479, work started on the 13th terminal. One of the funders, Derek Salter, was having financial problems, and tried to delay production. Eventually, he hired a gangster, Uncle, to plant bombs in the terminal, planning to blow it up for the insurance.

In 2487, the 'Invisible Assassin' was bought by Uncle in order to kill The Widow. The Judoon and then the Tenth Doctor caught wind of this and investigated the planet. Working with Nikki Jupiter and a Judoon, Rok Ma, the Doctor was able to track down the Invisible Assassin; however, it was quickly stolen away by the Widow's agents. When Rok Ma went to warn her that it was, in fact, a virus, he was sent back with it and subsequently captured by Uncle, who took the Assassin, believe it to be a weapon of great power. Rok Ma was then strapped to one of the bombs at the terminal. Thanks to the Doctor and Nikki, the plot was uncovered and a number of Judoon were sent in to disarm the bombs. Rok Ma was subsequently freed.

Shortly after, both Uncle and the Widow were accidentally killed when the former was checking to see if the device was working. He released the virus and they died. Following this, Derek Salter was arrested for his part in the plot and Rok Ma decided to stay on New Memphis and help Nikki to establish a detective agency. (NSA: Judgement of the Judoon)
