Mutter's Spiral

Mutter's Spiral, or Mutter's Cluster, (PROSE: The Taking of Planet 5) was the Time Lord designation for the star cluster in which Earth's solar system was located; (TV: The Deadly Assassin, The Invasion of Time) Gallifrey was located in the same galaxy as the Earth. (TV: Doctor Who, PROSE: The Devil Goblins from Neptune)

Most accounts described Mutter's Spiral as a galaxy, the same one known to humanity as the Milky Way or Galaxia Kyklos (WC: Shada, TV: Four to Doomsday) The name of Mutter's Spiral was taken from the cosmologist Stellion Mutter; (PROSE: The Taking of Planet 5) it could also be referred to as "Stellion's Whorl", (PROSE: Cybergeddon) "the Stellian Galaxy", (TV: The Mysterious Planet) or the Stellarian Spiral Galaxy. (PROSE: The Bloodletters) According to the Aubertides, however, Mutter's Spiral was a smaller section within the "the Stellarian Galaxy", with Gallifrey near the galaxy's core. (PROSE: Human Nature) Castellan Spandrell once informed President Romana of a Fortean Flicker across the Stellarian Galaxy. It was traced to the planet Hogsumm. (PROSE: The Highest Science, Happy Endings)

According to the Tenth Doctor, Mutter's Spiral contained about 50 billion planets. (PROSE: The Last Dodo) A power vacuum was opened in the galaxy after the end of the Last Great Time War. As such, the galaxy's history was then marked by centuries of warfare. (COMIC: Fugitive)

Mutter's Spiral contained Earth's solar system, (TV: The Deadly Assassin) Earth itself was located at galactic coordinates 58044 684884 (TV: The Pirate Planet) in Sector 8023 of the Third Quadrant. (TV: Logopolis)

Gallifrey was also located in Mutter's Spiral, (TV: Doctor Who, PROSE: The Devil Goblins from Neptune) in the Kasterberous system. (PROSE: Prisoners of the Sun) While most accounts placed Gallifrey at the centre of its galaxy, (PROSE: The Devil Goblins from Neptune, Interference - Book Two, Human Nature) or as near as possible without succumbing to a black hole, (PROSE: Interference - Book One) with 30,000 light-years between Gallifrey and the planet Earth, (PROSE: The Devil Goblins from Neptune) the Eighth Doctor mentioned that it was on "the other side of [the] galaxy" from Earth, 250 million light-years away. (TV: Doctor Who)

Also found within the galaxy were Draconia and the Ogron planet, the latter being located in what was believed to be an uninhabited sector until the 26th century, (TV: Frontier in Space) on the outer extremity of the galaxy (PROSE: The Romance of Crime) at galactic coordinates 0110011 by C2 (PROSE: Interference - Book One) or at 2349 to 6784.

The Doctor frequented Earth, a planet in Mutter's Spiral. (TV: An Unearthly Child, et al.) On one occasion, Earth was moved out of the galaxy to the Medusa Cascade by the Daleks. (TV: The Stolen Earth) The Second Doctor explained to his human companions Jamie McCrimmon and Zoe Heriot that "a whole galaxy to explore" motivated him to leave his home planet. On trial for breaking the Time Lords' non-interference policy, he cited the Daleks, Cybermen, Ice Warriors, Robot Yeti and Quarks as examples of "the evil of the galaxy" that he had fought whilst the Time Lords were content to observe. (TV: The War Games)

The Dark Empire was a period of tyrannical galactic rule by a mysterious and reportedly immortal entity called Horath, who crushed the civilisations of all but the most primitive planets. Horath was ultimately defeated circa 1000 BC, but could not be killed, so his body and his consciousness were divided and they were hidden at opposite ends of the galaxy. (TV: Enemy of the Bane)

The War Lord's people intended to conquer the galaxy, a thousand inhabited worlds, and amassed an army of humans abducted from across the history of Earth up to the 20th century for this purpose. The War Chief, a Renegade Time Lord, allied with the War Lords but intended to take over as Supreme Galactic Ruler himself, bringing the galaxy under a new order, one United Galactic Empire. The War Chief offered the Doctor a chance to rule with him, claiming that they could bring peace to the galaxy. The Doctor rejected this and thwarted the War Lords' plot, summoning the Time Lords to return the abducted humans. He himself took the TARDIS to a planet on the outermost fringes of the galaxy in an attempt to evade the Time Lords, only to be intercepted and put on trial. (TV: The War Games)

As recalled by Leef Apple Glyn Slitheen-Blathereen, while some Slitheen faced justice on Raxacoricofallapatorius, others fled to the farthest reaches of the galaxy. During an ultimately failed attempt to use a matter compressor to turn Earth's carbon atmosphere into a diamond, a Slitheen predicted that this would make the Slitheen the richest family in the galaxy. (TV: The Gift)

The Uvodni homeworld was located in the Spiral Cluster of the Dragon Nebula, thirty four thousand light years "across the galaxy" from Earth. The Uvodni were part of a planetary alliance that fought the Malakh as part of "the Ghost Wars of the Horsehead Nebula", which was ended with an armistice by 1998. (TV: Warriors of Kudlak)

In 2009, Commander Kaagh acquired the consciousness of Horath in the Kaldeann Cluster on behalf of the Bane Kindred; by reuniting it with Horath, it would have allowed them to take over the galaxy. However, Kaagh joined forces with Mrs Wormwood, a rogue Bane, and the two plotted to become emperors of the galaxy together. Wormwood vowed that the galaxy would tremble when the Eye of Horath opened. Ultimately, however, Kaagh was betrayed by Wormwood, and so he threw her and himself into a portal containing Horath's body, which had briefly opened at Stonehenge on Earth. (TV: Enemy of the Bane)

The Tenth Doctor observed that the death of Adelaide Brooke in 2059, a fixed point in time, led to her granddaughter, Susie Fontana Brooke, taking humanity out into the galaxy. (TV: The Waters of Mars)

In the 22nd century, the Daleks successfully conquered and occupied the planet Earth only to be defeated by the First Doctor and human resistance fighters, earning both the Doctor and humanity the Daleks' long-standing enmity. (TV: The Dalek Invasion of Earth, TV: The Chase, PROSE: Dalek: The Astounding Untold History of the Greatest Enemies of the Universe) Gordon Lowery was aware that the Daleks had invaded Earth "a couple of times". (PROSE: Mission to the Unknown)

In the 26th century, the Earth and Draconian Empires spread throughout the galaxy in opposition to each other, resulting in the Draconian War. Though the conflict was ultimately resolved, the Daleks, with the assistance of and their Ogron servants, planned to reignite the conflict, which they intended to destroy both empires and thus open the way for them to conquer the galaxy. This plan, however, was thwarted by the Third Doctor. (TV: Frontier in Space) Nevertheless, the Daleks did launch an invasion of the galaxy, leading to the Second Dalek War. (TV: Planet of the Daleks, PROSE: Prisoner of the Daleks, Dalek: The Astounding Untold History of the Greatest Enemies of the Universe, Dalek Combat Training Manual)

In the aftermath of the war, the long Rutan-Sontaran War reached a critical phase when the Rutan Host destroyed the Sontaran homeworld, Sontara. The Seventh Doctor helped the endangered Sontarans to preserve their species while making them promise to wipe all knowledge of humans from their racepool, thus sparing humanity from their "imperial ambitions" for a number of centuries. (COMIC: Pureblood) The outbreak of the Third Dalek War some time later only worsened the burden felt by the Earth Empire and their expansionist phase came to an end. Planets such as Mechanus were never colonised and the Mechonoids created to prepare these planets for colonisation were forgotten about. (PROSE: The Chase)

In 4000, Gordon Lowery recalled the Movellan Wars as one of the last instances of Dalek activity in the galaxy, a thousand or more years before then. (PROSE: Mission to the Unknown)

In the half a millennium leading up to the year 4000, the Daleks, having fallen back from their ambitions to conquer Mutter's Spiral following the conflict with the Combined Galactic Resistance and the war with the Mechanoids, advanced towards the Outer Galaxies for new conquests. Whilst the limited observation technology of the Earth Empire observed the Dalek conquests of 70 planets in the Ninth Galactic System and 40 more in the constellation of Miros, both millions of light-years from their galaxy, later historians understood that these conquests were a mere fraction of extra-galactic Dalek gains. The Anti-Dalek Force reported that the Daleks were suspected to be signing non-aggression pacts with other powers in the "outer planets".

With Dalek gains in the Outer Galaxies consolidated by the dawn of the 40th century, the Dalek Supreme began the Daleks' master plan, which would take a century to complete. (PROSE: Dalek: The Astounding Untold History of the Greatest Enemies of the Universe) In the year 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 invade the galaxy and 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)

According to one account, the failure of the 4000 invasion attempt led the Dalek Supreme, who escaped Kembel in a critical condition, to return to Skaro and order that Dalek forces retreat from "the human galaxy", preparing a new strategy as the Daleks expanded their empire across the Outer Galaxies. The Dalek Wars ended, for a time, though further conflicts awaited in the Dalek-Movellan War, the Imperial-Renegade Dalek Civil War and the Last Great Time War.

(TV: 42) According to another account, humanity was confined to Mutter's Spiral until the discovery of the intergalactic drive in the 54th century. (AUDIO: The Star Men)

In the 47th century, (PROSE: Dalek Combat Training Manual) Davros established himself as the Great Healer of Tranquil Repose, a facility containing deceased bodies awaiting revival on Necros. Whilst select Resting Ones were converted into Daleks, Davros saw that the "lesser intellects" became the source of a high protein concentrate which fed the galaxy as their part of it expanded, eliminating the famine which, until then, had been one of its major problems. Kara managed the factories which produced the protein products, ostensibly supporting Davros whilst employing Orcini as an assassin to attempt to kill Davros, claiming that Orcini's reputation was like a fanfare through the galaxy. Takis, who worked at Tranquil Repose, believed that the idea of the place did not work as the galaxy could barely support the people alive now. (TV: Revelation of the Daleks)

Another major power was Josiah W. Dogbolter's Intra-Venus, Inc., a company rich enough to own Venus, Mars, and Jupiter. The Skeletoids tore through the galaxy, decimating the Daleks and Cybermen and coming close to the Federation. They were stopped by a coalition of heroes including the Sixth Doctor and Kaon.

Alternate timelines
When Rassilon joined forces with the Cyberiad, the Cybermen launched a fleet of Cyber-Arks out from prehistoric Earth, seeding the developing Mutter's Spiral with Cyber-Technology. This created an alternate timeline where the Cyberiad became the galaxy's dominant force, upgrading or destroying their rival powers and even going on to fight in the Last Great Time War. This timeline was later undone when a remorseful Rassilon joined forces with the Twelfth Doctor. (COMIC: Supremacy of the Cybermen)
