Outer Galaxies

The Outer Galaxies, also referred to as the outer worlds, (PROSE: Mission to the Unknown) were a group of galaxies which sent representatives to the Galactic Council.

The "great powers" of the Outer Galaxies included the Fifth Galaxy and the Tenth Galaxy, which was the largest of the group, the planets Gearon, Sentreal, and Malpha, and the planets of the Beaus, Warrien, and Planktus, who attended the Intergalactic Conference of Andromeda. Also represented was the Celation Nebula, (TV: The Daleks' Master Plan) which drifted along the Mutter's Spiral. (AUDIO: The Perfect Prisoners)

In 4000, the great powers of the Outer Galaxies, along with Mavic Chen, the Guardian of the Solar System, formed the Great Alliance with the Daleks in an attempt to obliterate Earth with the Time Destructor. The Daleks' treachery was revealed, and the surviving members of the Outer Galaxies fled to warn their planets and join forces, (TV: The Daleks' Master Plan) which lead into the Great War against the Daleks. (PROSE: The Evil of the Daleks)

Later in the 41st century, surviving members and heirs of the Outer Galaxies representatives formed the Syndicate to control Earth and get revenge on the Fourth Doctor, (AUDIO: The Perfect Prisoners) although they denied Zephon membership. (AUDIO: Time's Assassin)

In an alternate timeline in which he spent three months on Urbinia, located in the Third Galaxy, the First Doctor delivered "highly commended" lectures about alchemical advances in the Outer Galaxies at Kiria City's university. (AUDIO: Daughter of the Gods)
