Skaro

Skaro was the homeworld of the Thals, of the Kaleds, and, later and most infamously, of the Daleks. The latter came to be during the Thousand Year War which opposed the Thals to the Daleks' humanoid ancestors, one of whom, the scientist Davros, played a key role in the Daleks' genesis. After its permanent disfigurement and irradiation by this war, Skaro became a well-nigh inhospitable world, infested with hordes of mutant creatures, and saturated by radioactivity that required regular drug doses to combat. Subsequent attacks on Skaro caused by the Dalek occupation would nearly destroy it in its entirety, until it was remade by the Daleks and returned to power with the assistance of Davros and became the centre of the Dalek Empire once more.

Astronomical data
Skaro was located in the Seventh Galaxy and nine Galaxies away from Earth. (PROSE: The Infinity Doctors, COMIC: Legacy of Yesteryear) Another account described Skaro as being "in the next universe but one". (PROSE: Doctor Who in an Exciting Adventure with the Daleks) It was the twelfth planet in its solar system, (TV: "The Ambush", PROSE: The Infinity Doctors) and it had at least two suns. (PROSE: The Stranger) It had a similar atmosphere, climate and gravity to Earth, though it was plagued by sulphuric rain. (GAME: City of the Daleks, TV: Asylum of the Daleks) Skaro's nearest neighbour was a planet called Alvega. (COMIC: The Amaryll Challenge)

Landscape
Skaro had a single large continent during the Thousand Year War on which the Kaleds and Thals evolved. The continent was divided in two by an immense mountain range. (TV: Genesis of the Daleks)

Much of Skaro was a wasteland, devoid of all life after centuries of war. (TV: Genesis of the Daleks)

Thousands of years later, the Daleks and Thals lived on two separate continents of Darren and Davius before the Neutronic war. Skaro was a world full of art, creativity and ideas and the two races lived in peace. (COMIC: Genesis of Evil)

A jungle once grew near the Dalek City. Following an exchange of neutron bombs, the jungle was petrified. Radiation levels across most of the planet remained high. There were less irradiated plateaus where the Thals lived. (TV: The Daleks)

Hydrothermal activity was indicated by the presence of place names like "Geyser Swamp". However all bodies of liquid may not have been composed of water. At least one river was known to be comprised of sulphuric acid, and the geysers in Geyser Swamp spewed mercury, rather than steam. (COMIC: Duel of the Daleks)

The planet had polar ice caps. The mountains at one of the poles were known as the Polar Mountains. (COMIC: Legacy of Yesteryear)

After being restored by the Daleks, Skaro appeared to have been, to an extent, returned to the pristine state it held before it became war-torn, as it was safe for Clara Oswald, and the Twelfth Doctor to walk around without worry of radiation sickness (TV: The Magician's Apprentice) and the skies were clear enough to see the sun rise and fall. (TV: The Witch's Familiar)

Continents/regions
There were various regions on Skaro, notably Davius, Dalazar, the Wastelands and Darren.

Rivers, lakes, and oceans
The Ocean of Ooze was present on Skaro, as was the Geyser Swamp.

There was a lake called Drammakin Lake/Lake of Mutations.

There were several seas such as the Bottomless Sea, the Sea of Acid, the Sea of Rust the Serpent Sea and even the River of Whirling Waters.

Islands
The Forbidden Islands were on Skaro.

Settlements
Many cities and settlements existed on Skaro throughout its history, though the Thousand Year War made much of the planet's surface an inhospitable wilderness. The Darrien province and the Kaled Dome dated back to the Kaled/Thal occupation of the planet, (TV: The Daleks) but by far the most notorious and enduring conurbation on Skaro was the Dalek City, built by the Daleks immediately after their emergence (COMIC: Power Play) and used as their main base of power on Skaro throughout their history. (TV: The Daleks, The Evil of the Daleks, The Magician's Apprentice, PROSE: War of the Daleks) According to one account, the Daleks' capital city was Kaalann. (GAME: City of the Daleks)

Native life
All Skarosian life had DNA, (AUDIO: Corruption) which was fundamental type 467-989. (TV: Daleks in Manhattan) Most of Skaro's animal and plant life became extinct as a result of the Thousand Year War. (AUDIO: Corruption) Some of the survivors included the Varga plants (TV: Mission to the Unknown) and Slythers. (TV: The Dalek Invasion of Earth) The Lake of Mutations was home to a variety of life-forms, including the terrorkon. (TV: The Daleks, COMIC: The Terrorkon Harvest) At least one area of the planet was inhabited by large dinosaur-like creatures. (COMIC: The Planet of the Daleks) Another Skarosian life form were magnedons; most perished in the war, leaving the landscape littered with their metallic exoskeletons. (TV: The Daleks)

Several sentient species evolved on Skaro, including the Dals, Tharons, Kaleds and Thals. By the time of the Thousand Year War, the Tharons and Dals had died out. (AUDIO: Purity) The Mutos were mutated Kaleds and Thals, and the species which became most associated with Skaro, the Daleks, likewise descended from the Kaleds. (TV: Genesis of the Daleks) According to one divergent account, which made no mention of the Kaleds, the sapient species at odds with the Thals were short, large-headed, blue-skinned humanoids who already called themselves "Daleks". (COMIC: Genesis of Evil) Yet another dissenting account uniquely held the Daleks' planet of origin to not have been Skaro at all but rather Ameron. (PROSE: We are the Daleks!)

Intelligent insects called Zomites also lived on Skaro even well into the metallic Daleks' occupation of the planet; the Daleks considered them a "pest" and worked to destroy them, even allowing other "inferior" creatures to live on Skaro if they helped in the extermination of the Zomites. (COMIC: The Daleks Destroy the Zomites)

Pre-War history
Though Thals used the same name for their world, in the Kaled language, "Skaro" meant "home". (PROSE: War of the Daleks)

100 million years prior to the Thousand Year War, the ancestors of the Kaleds diverged from those of the Thals. (AUDIO: Corruption)

A war-torn world: creation of the Daleks
According to one account, by the time of the creation of the cyborgs known as the Daleks, the Kaleds and the Thals fought the Thousand Year War over the wasteland adjacent to the Kaled Dome. (TV: Genesis of the Daleks) Whilst differing as to the length and circumstances of the war, many other accounts agreed that the Daleks had come about in the aftermath of a war between the Daleks' humanoid forefathers and the Thals. (TV: The Daleks, COMIC: Genesis of Evil)

Davros was a Kaled child who grew up in the midst of the War. The Twelfth Doctor, accidentally landing in the middle of the War, once passed the young Davros the Doctor's sonic screwdriver to speak to him across a minefield of handmines, not realising who he was going to grow up to be until the boy said his name. The Doctor reconsidered helping Davros get out of the minefield, and later, a future version of the Twelfth Doctor arrived on Skaro and pointed a gunstick at Davros in an attempt to save his friend, "the only way [he could]". (TV: The Magician's Apprentice) He then proceeded to destroy the handmines and save Davros to teach him the concept of mercy before taking him home. (TV: The Witch's Familiar)

Technology had devolved in this time. A Scientific Elite governed the Kaleds. By this phase of the war, biological and nuclear weapons had begun to cause mutations known as Mutos. (TV: Genesis of the Daleks) The Thals also underwent many mutations as a result of the War, though they eventually reverted to a humanoid form similar to their original one. (TV: The Daleks)

Although some accounts stated that these mutations of the Thals' nemeses led to their becoming the familiar tentacular blobs of hateful flesh who sealed themselves in armoured travel machines to become the Daleks, (TV: The Daleks, COMIC: Genesis of Evil) another held that before it came to that, the Kaled scientists saw the increasing number of Mutos as the end of their species in its "pure" form. Davros, now the Kaled chief scientist, decided to accelerate the mutations on purpose to determine their "ultimate form" and placed the results in travel machines, though not before making his own alterations to their genetic code to make sure that they would be heartless killers with an innate belief in their own supremacy, making them the perfect warriors as conceived of by Davros: "soldiers who would never, ever stop". (TV: Genesis of the Daleks, The Magician's Apprentice)

The Fourth Doctor, transported to this time period by the Time Lords to prevent a possible future where the Daleks would rule the universe, was given the chance to destroy the first incubating Dalek embryos but feared that he had not the moral right to wipe an entire species of sentient lifeforms from history, never mind how infamous. The Doctor nevertheless played a part in entombing these early Daleks in their bunker, from which he hoped it would take them centuries to escape. The Daleks still survived and promised to re-emerge. (TV: Genesis of the Daleks)

A neutronic war capped off the long-standing conflict between the Thals and their nemeses, leaving Skaro utterly inhospitable to the lifeforms who had flourished there before it. Some Thals survived by developing an anti-radiation drug, (TV: The Daleks, COMIC: Genesis of Evil) whilst what few numbers of their humanoid enemies had survived the neutronic strike died of radiation poisoning. (COMIC: Genesis of Evil) The Daleks, on the other hand, could survive in the irradiated atmosphere thanks to their travel machines. (TV: The Daleks)

After building a Dalek City for themselves, (COMIC: Power Play) the Daleks, who believed the Thals to have been utterly annihilated at the end of the war, though they had in truth merely faded into obscurity by forsaking most technology and becoming peaceful farmers, (TV: The Daleks) turned their attention towards the conquest of space, and, notably targeting Earth in the 22nd century (though that invasion was thwarted by the Doctor), steadily forged a sprawling Dalek Empire. (TV: The Dalek Invasion of Earth, Resolution, COMIC: The Amaryll Challenge, Legacy of Yesteryear, The Road to Conflict et al.)

The aftermath of the Thousand Year War, Neutronic War and Dalek Creation
Centuries passed. Radiation levels dropped, though they still presented a danger to humanoid life.

The Thals believed they were now of intellectual and physical perfection. They lived a simple pastoral and pacifist lifestyle. The Thals never ventured into the Dalek City near the petrified forest or showed any curiosity about it. Because of their dependence on static electricity to move about, the Daleks stayed within the city. The First Doctor landed the TARDIS on Skaro, not knowing the planet's dangers. Ironically, the Daleks' discovery of the Doctor and his companions, who came from off-world, caused them to wonder about and to fear the existence of other sentient life on Skaro.

The Doctor's companion, Ian Chesterton, taught the Thals to use violence in self-defence, in order to protect themselves against the xenophobic Daleks who threatened them.

The Daleks came to know, during this time, that they needed high radiation to live. With levels subsiding and their lives threatened, the Daleks proposed to set off another neutron bomb. As this would take too long, the Daleks instead planned to release radiation from nuclear reactors into the atmosphere.

A combined effort by the Doctor, his companions and the Thals resulted in the electricity supply for the city being cut off, leaving the Daleks immobile and powerless. The Doctor and his companions believed the Daleks had died to the last, and lamented that they had not found another, less bloody way to save the Thals. (TV: The Daleks)

The Doctor, Ian and Barbara Wright visited Skaro again, where they inadvertently helped the Daleks exterminate their pests, the Zomites. (COMIC: The Daleks Destroy the Zomites)

Spaceflight era and after
By the 26th century, it seemed that the Thals had reclaimed Skaro from the Daleks. (TV: Planet of the Daleks)

In another era, in the Dalek City, the Dalek Emperor ruled an empire which spanned both space and time. (TV: The Evil of the Daleks)

The Dalek Emperor moved Skaro into Earth's solar system in the 25th century in an attempt to conquer the system and enslave humanity. (COMIC: Invasion of the Daleks)

The Master's execution took place on Skaro and the Seventh Doctor made arrangements to go there to pick up the remains. (TV: Doctor Who) The fact that the Doctor could do this indicated a somewhat less hostile attitude of the Time Lords towards the Daleks under President Romana. (PROSE: Lungbarrow)

Destruction of Skaro
Skaro was destroyed when, as planned by the Seventh Doctor, (TV: Remembrance of the Daleks) the Hand of Omega detonated its second sun, (PROSE: The Stranger) causing it to go supernova. The stellar explosion released a shockwave which quickly struck the nearby world. It ripped and burned the planet to smithereens. (TV: Remembrance of the Daleks) However, at least part of the planet persisted, though in ruins and with the conditions of its environment even worse than after the Thousand Year War. (TV: Asylum of the Daleks)

Supposed survival of Skaro
The Dalek Prime later claimed that Skaro had not in fact been destroyed. The Daleks, during their invasion of Earth in the 22nd century, had discovered records that showed Skaro's destruction. Failing to change history altogether, the Daleks had instead decided to terraform the planet Antalin into a decoy Skaro and manipulated both Davros and the Doctor, ensuring that both believed Antalin's coordinates to be Skaro's. Thus, as the Eighth Doctor discovered in horror when both he and Davros returned to the Dalek Prime's Skaro, it was Antalin which the Hand of Omega had destroyed, and Skaro remained, intact, as the Dalek Prime's power base.

Davros, unwilling to believe that his own creations had tricked him so thoroughly that he didn't know his own home planet, instead reasoned that Skaro had indeed been destroyed, but that the Dalek Prime may then have terraformed some other planet to resemble the Daleks' old home world and then fabricated the story of Skaro's survival — by Davros's recknoning, the Daleks under the Prime's command would have been too young to have known the original Skaro, and thus would not have known any better. (PROSE: War of the Daleks)

Whoever was right of Davros or the Dalek Prime, Skaro once again served as the base of the Dalek Empire during the Last Great Time War in which they fought the Time Lords. Opposing Gallifrey, Skaro's history was time-locked to prevent further Time Lord incursions. (AUDIO: Legion of the Lost) The Time Lords planned to unleash a genetically engineered breed of Dalekanium-eating Vashta Nerada against Skaro but were forced to abandon the project following an incident on Synthesis Station. (AUDIO: Day of the Vashta Nerada)

After escaping the end of the Time War, Dalek Caan nevertheless claimed that the planet was "gone, destroyed in a great war". He contrasted what happened to Skaro with New York City, where "versions of this city [stood] throughout history". (TV: Daleks in Manhattan)

Resurrection of Skaro
After the new Progenitor Daleks escaped, (TV: Victory of the Daleks) they rebuilt Skaro, (TV: The Witch's Familiar) the Dalek Emperor, their city of Kaalann and later their whole empire. The Eleventh Doctor discovered that the New Dalek Empire had invaded Earth in 1963. He went to the rebuilt city of Kaalann and discovered that the Daleks had found the Eye of Time, which helped them alter Earth's timeline. Using the Eye, the Doctor travelled to Kaalann in its ruined state before the return of the Daleks. He sabotaged the Daleks' vision, allowing him to deactivate the Eye. The timeline returned to normal and the New Dalek Empire and their 1963 invasion of Earth were erased. Skaro reverted to its ruined condition. (GAME: City of the Daleks)

An area of the petrified jungle was salvaged by humans at some point close to the 41st century and taken to Earth's Station 7 for research. (COMIC: The Only Good Dalek) The Eleventh Doctor revisited the devastated Skaro after being summoned by a woman called Darla, who claimed to have been looking for her daughter, Hannah. He did this with great reluctance, even going as far as avoiding saying its name. However, this was a trap to capture him; Darla had been taken over by the Daleks. (TV: Asylum of the Daleks)

A dying Davros returned to Skaro, which had been completely restored by this point, after barely surviving the destruction of his Crucible at the hands of the Meta-Crisis Tenth Doctor, claiming "Where does an old man come to die? But with his children." Davros later sent Colony Sarff to find the Twelfth Doctor and bring him to Skaro. The Doctor willingly came and was joined by and Clara Oswald. The building Sarff's ship landed in appeared to be a space station floating in space but turned out to actually be on Skaro with the rest of the planet invisible to the rest of the universe. Whilst Davros occupied the Doctor, showing him conversations from their previous encounters, Missy and Clara were seemingly exterminated. (TV: The Magician's Apprentice) However, Missy had rewired their vortex manipulators to absorb the energy and teleport away. Needing to get back into the city, they breached the sewers. There they discovered ancient Dalek mutants who, unable to die, had devolved into sludge. Davros was able to convince the Doctor to give up some regeneration energy to Davros to sustain him until the sunrise. The cables surrounding the Doctor were actually Colony Sarff, who trapped the Doctor. Regeneration energy was transmitted to every Dalek on Skaro, and the Daleks were reborn with new Time Lord powers. However, this was a ruse by the Doctor. The energy regenerated the sewer Daleks, who destroyed the Dalek city. The Doctor and Clara left in the TARDIS, leaving Skaro's Dalek city a crumbling ruin. (TV: The Witch's Familiar)

Alternate timelines
In an alternative 22nd century, the Daleks conquered Earth after a World War III had occurred there in the 20th century. The Daleks transported Earth's mineral wealth back to Skaro. (TV: Day of the Daleks)

In another alternate timeline, the Dalek Emperor destroyed Skaro by exploding the planet in the 43rd century when it came under attack by the Mutant Phase. (AUDIO: The Mutant Phase)

In another alternate timeline, the planet suffered a similar history of desolation after an accidental neutron war. However, the Daleks developed as a peaceful species rather than the war-like creatures from the original timeline. Skaro in this timeline was, according to the Doctor, the universal centre of civilisation, philosophy, democracy and art. Species from all over the Universe came to Skaro, even the Time Lords. However, this timeline was unstable and solar activity of the sun of Skaro began increasing before the Doctor restored the timeline. (PROSE: The Ripple Effect)

In another alternate timeline, the Fifth Doctor and Peri encountered Cybermen on Skaro. (COMIC: Prologue: The Fifth Doctor)

Other Skaros
Just as they colonised "New Skaro," the Daleks made other planets they conquered into "Skaros," as they did to the Seriphia Galaxy (AUDIO: The Apocalypse Element) and planned to go to the Sunlight Worlds. (PROSE: The Dalek Generation) This was because the word "Skaro" in the Dalek tongue simply meant "home". (PROSE: War of the Daleks)

Minor references
The Tenth Doctor once stated, "A foe that cannot be killed, that would put the fear of Skaro into you". (PROSE: The Resurrection Casket)

As recorded by the Testimony, the "Destroyer of Skaro" was a name for the Doctor. (TV: Twice Upon a Time)

Behind the scenes
According to the non-narrative source The Dalek Pocketbook and Space Travellers Guide, the Island of Gushing Gold was a landmark on Skaro which jetted molten gold into the air.
