Skaro Skaro was the homeworld of the Kaled s and the Thal s , devastated by the Thousand Year War . It was during this conflict that Davros created the Dalek s , who took Skaro for themselves . After its permanent disfigurement by war , Skaro became a well - nigh inhospitable world , infested with hordes of mutant creatures . 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 . 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 bomb s , 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 was known to have 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 " ) Known geographic features . Continents / regions . There were various regions on Skaro , notably Davius , Dalazar , the Wastelands and Darren . Mountains . The mountains on Skaro included the Polar Mountains and the Radiation Range . 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 . Some settlements included the Darrien province , the Kaled Dome and the main Dalek City , 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 plant s ( TV : " Mission to the Unknown " ) and Slyther s . ( 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 Dal s , Tharon s , Kaled s and Thal s . By the time of the Thousand Year War , the Tharons and Dals had died out . ( AUDIO : " Purity " ) The Muto s were mutated Kaleds and Thals . ( TV : " Genesis of the Daleks " ) History . 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 " ) One account states that both the Kaleds and the Thals were descended from humans transplanted from Earth to Skaro as an experiment by the Halldon s . ( PROSE : " We are the Daleks ! " ) 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 " ) During Davros ' childhood , the Twelfth Doctor passed Davros the Doctor ' s sonic screwdriver to speak to him across a minefield of handmine s , 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 I can " . ( 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 weapon s had begun to cause mutations known as Muto s . The Kaled scientists saw this 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 . These creatures then became the successors to the Kaleds , the Daleks . The Fourth Doctor , transported to this time period by the Time Lord s to prevent a possible future where the Daleks would rule the universe , played a part in entombing the Daleks in the Kaled bunker . The Daleks still survived and promised to re - emerge . ( TV : " Genesis of the Daleks " ) Despite the predominance of this account about the creation of the Daleks , the Daleks did not fully evolve until the aftermath of a Neutronic war . ( COMIC : " Genesis of Evil " ) From here , they used Skaro as their base of operations and built a Dalek city . By the 22nd century , they had learnt of Earth ' s existence . ( COMIC : " Power Play " , " Legacy of Yesteryear " 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 companion s , 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 . ( TV : " The Daleks " ) 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 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 . An attempt to change history was unsuccessful . The Daleks decided to terraform the planet Antalin to resemble Skaro as a decoy and manipulated Davros and the Doctor into ensuring that Antalin was destroyed in place of the original Skaro . ( PROSE : " War of the Daleks " ) Skaro once again served as base of the Dalek Empire during the Last Great Time War in which they fought the Time Lord s . Opposing Gallifrey , Skaro ' s history was time lock ed 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 " ) Evidently , Skaro was ultimately destroyed by the end of the war , after which Dalek Caan claimed that the planet was " gone , destroyed in a great war . " It 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 was erased . Skaro reverted to its ruined condition . ( GAME : " City of the Daleks " ) An area of the petrified jungle was salvaged by human s 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 his with great reluctance , even going as far as avoiding calling 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 the Daleks developed as a peaceful species . 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 : " " ) 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 do to the Sunlight Worlds . ( PROSE : " The Dalek Generation " ) 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 source " The Dalek Pocketbook and Space Travellers Guide " , the Island of Gushing Gold jetted molten gold into the air .
