Kaalann

Kaalann was the capital city of Skaro, the homeworld of the Daleks.
 * Kaalann may be the same city as the Dalek City seen in previous stories. The Dalek Handbook confirms this but suggests differences caused by an altered timeline.

City of the Daleks
The Eleventh Doctor and Amy Pond visited Kaalann in an alternate timeline, travelling there from a devastated London in 1963. The Daleks had rebuilt a ruined Kaalann and had altered the timeline using a natural occurrence once held by the Time Lords called the Eye of Time. However, the Doctor managed to deactivate the Eye, returning the timeline to normal. Kaalann was also returned to normal, becoming ruined, as it had been before the Progenitor Daleks found it.

The Doctor and Amy explored Kaalann's many different areas in the city while looking for the device that the Daleks were using to alter the timeline.

Storerooms
Kaalann had several storerooms with discarded Dalek parts. It was in one of these that the Doctor landed his TARDIS.

Factories
Kaalann was used by the New Dalek Paradigm as a giant factory. Daleks were produced on a production line. This area was of higher security; it was heavily guarded by Drone and Scientist Daleks. The factories were connected to the other rooms by corridors infested with Varga plants.

Visualiser Room
The Visualiser room was a large room where the Daleks recorded and monitored all Dalek activity across the universe. It was controlled by the Visualiser Eye, a large Dalek Eye on one of the walls. The room was full of large data banks and also contained three consoles. The Doctor had to use these consoles to deactivate the Eye's security beam.

Supreme Council Chamber
The Supreme Council Chamber was where the Dalek Emperor and the Eye of Time were located. The chamber had two levels. The Emperor and the Eye were located on the top level. It was in this room that the Doctor deactivated the Eye and reversed the timeline. (VG: City of the Daleks)

Appearance
Kaalann's atmosphere was heavily polluted by the Daleks' factories. Thirty percent of the atmosphere in the area was made up of sulphuric acid. The sky had an orange colouration and acid rain constantly fell over the city.

Kaalann had many tall buildings, including the Supreme Council Chamber. (VG: City of the Daleks)
