Earth (Unbound Universe)

Earth was a planet in the Unbound Universe. Similarly to its counterpart in N-Space, it was the home planet of humanity and frequently visited by the Doctor. The Time Lords attempted to exile the Doctor to the planet.

History
Earth was visited numerous times by the Doctor, whose TARDIS became stuck in the form of a 1960s British police box. On two occasions he encountered Alistair Lethbridge-Stewart, one of which involved defending Earth from robot Yeti.

During the 1970s, Earth suffered numerous alien incursions, including the "plastic purges", the Ambassadors (who left a string of craters across America), (AUDIO: Sympathy for the Devil) and the Renegade faction of Daleks. (AUDIO: Masters of War) UNIT, led by Alistair Lethbridge-Stewart, defended the planet and had to resort to increasingly desperate methods, such as bombing Surrey. UNIT's many failures led Alistair eventually being driven from the organisation.

The Master became trapped on Earth during the 1970s, having been separated from his TARDIS. Initially he worked for the United Nations, however defected to China and helped the government by using an alien mind parasite to create the Ke Le Divisions.

In punishment for his interference, tne Doctor was exiled by the Time Lords, arriving in Hong Kong on the eve of its transfer from British to Chinese control in 1997. There he was reunited with Alistair, now running a pub there, and encounteted the Master who was fleeing China after losing his influence there. They stopped the Master obtaining the last mind parasite so he could still control the Ke Le Divisions and took it to where the Chinese government were destroying the rest, using the explosion to disable inhibitor imposed on the Doctor's TARDIS, enabling him to leave Earth. The Master was left trapped in Hong Kong as the Ke Le Divisions sent to assert Chinese control of it went mad without the parasites. (AUDIO: Sympathy for the Devil)
