Though some accounts dated the Dalek City to before the Thousand Year War (TV: The Daleks), another held that shortly after their creation from the ashes of their humanoid forefeathers, the Dalek mutants spent two months rebuilding a city for themselves. To conceal the city from potential threats, the metallic sands of the desert surrounding it were magnetised, allowing the Daleks to pull the sand over their city within minutes, hiding it beneath an immense dune.(COMIC: Power Play)
The Daleks beneathEditAt the time of the First Doctor's visit to the planet, the Daleks lived not in the city itself, but rather below it where they thought they were shielded from radiation.
Beneath their city, the Daleks monitored the drop in radiation outside and they made plans to leave their casings and venture outside once more when the radiation had dropped to a safer level. The entire city ran on static electricity transmitted through metal floors, which the Daleks of this era of Skaro history required to power their casings. As a consequence of this dependence, the Daleks were unable to leave their city. They were unaware that a group of Thals had also survived the neutronic war.
Early days of the Dalek EmpireEdit
After the Daleks were defeated in the Thal-Dalek War, the Thals moved into the city. (TV: The Daleks) However, the Daleks soon returned to occupy the city once more. (COMIC: Plague of Death, (TV: The Evil of the Daleks et alt.)The Dalek City was destroyed by the Monstrons and their robotic Engibrains during their brief conquest of the planet Skaro. However, the Monstrons had failed to destroy the Daleks themselves, only trapping them underground; they managed to free themselves whilst another Daleks, taken prisoner by the Monstrons at an earlier stage of invasion, sacrificed itself to set off a volcano and exterminate the Monstrons themselves with it. The Daleks then set about rebuilding their city. (COMIC: The Menace of the Monstrons)
Performing hypnosis, the Master showed Victoria Waterfield the Dalek city on Skaro during the period before the Daleks had first left the planet, offering her a chance to destroy them with the Darkheart. (PROSE: The Dark Path)
The Great Civil War and aftermathEdit
During the war between the Humanised Daleks and the Daleks ruled by the Emperor Dalek, the Second Doctor, having visited the Daleks' City before, knew how to navigate its winding corridors. Fighting between the two groups of Daleks devastated the city, ending the Great War. (TV: The Evil of the Daleks, PROSE: The Evil of the Daleks)
After the Civil War, the Daleks rebuilt the Dalek City and introduced a new command structure involving Gold Daleks which outranked the Black Daleks. (TV: Day of the Daleks, TV: Frontier in Space, PROSE: Day of the Daleks)
Under the Dalek PrimeEdit
Following the Imperial-Renegade Dalek Civil War, the Dalek Prime controlled the Dalek city and it had a spaceport. The city contained a war room where the Daleks could monitor their numerous battle fronts while elsewhere on Skaro there were industrial facilities for their war machine. A brief but destructive war broke out in the city following Davros's staged trial, between the Daleks loyal to the Dalek Prime and those who found Davros a worthier leader for the Dalek nation. As anticipated by the Dalek Prime, who had allowed the conflict to break out to root out Daleks of wavering loyalty, his side won, though Davros somehow survived the ordeal. (PROSE: War of the Daleks)
The Last Great Time WarEdit
The City still served as the Daleks' main base during the Last Great Time War; after the Cult of Skaro was formed by the Dalek Emperor, they headed to the secret Strategy Chambers of the Cult of Skaro, a special area of the city secluded from the roaming grounds of other Daleks. (PROSE: Birth of a Legend)
Beyond the Time WarEdit
Though the Cult of Skaro originally believed their entire planet was "gone… destroyed in a great war", (TV: Daleks in Manhattan) the planet was later "brought back" by the New Dalek Paradigm (GAME: City of the Daleks, TV: Asylum of the Daleks), and the Dalek City with it. It had been fully restored to its former glory when a dying Davros returned there to finish his life "with his children", (TV: The Magician's Apprentice) before hatching a plan to extend his life and strengthen all the Daleks on Skaro using regeneration energy stolen from Twelfth Doctor. Davros had brought with him Colony Sarff, a gestalt entity composed of sentient snake-like beings, whom he named "head of security" for the City whilst he resided there. The Dalek City's sewers were, by this point, fairly full with the resentful elderly Daleks too decayed to steer their casings anymore and who had been dumped there by the newer generation. (TV: The Witch's Familiar)
DestructionEditDavros's scheme to steal regeneration energy from the overly compassionate Time Lord had been anticipated by the Twelfth Doctor, who let him go through with the theft. This was due to a fault in Davros's plan which the Kaled scientist had failed to anticipate: channeling regeneration energy into "every Dalek on Skaro" meant that the rotting Daleks in the sewers would also be rejuvenated. The millions of rabid, insane Dalek mutants soon tore up through the floors of the Dalek City, hungry for vengeance on the newer generations, and destroyed them alongside the City. (TV: The Witch's Familiar)
Behind the scenes Edit
The Dalek Handbook states that the city was named Kaalann. Dialogue in the video game City of the Daleks suggests that this city is the same as the Kaalann in the game, when the Eleventh Doctor says of Kaalann, "Last time I saw it, it was in ruins and the Daleks had fled".
