New Skaro was, presumably, the new homeworld of the Daleks, established by the 26th century when Ace was in Spacefleet. (PROSE: Birthright)
Working with the Reborn Master, the Dalek Time Controller created an alternate timeline where it took over Earth from Paris in 1921. By 1961, the planet was "New Skaro" and converting the bio-matter of humans, Sontarans, Draconians and other aliens into a New Dalek Paradigm. (AUDIO: Master of the Daleks)
The Cult of Skaro later planned to turn Earth in 1930 into "New Skaro". (TV: Daleks in Manhattan/Evolution of the Daleks)
The Time Lords identified the "rebuilt" Skaro in the time of the New Dalek Paradigm, which the Eleventh Doctor visited prior to the Asylum Incident, as "the new Skaro". (PROSE: Dalek Combat Training Manual, TV: Asylum of the Daleks)
Behind the scenes
- The Terrestrial Index, which placed the Dalek Civil War at the end of Dalek history, claimed that the Daleks were forced to adopt a replacement homeworld after being forced off Skaro by the Thals during the 25th century Second Dalek War. Though the Daleks eventually defeated the Thals on Skaro following the 26th century Third Dalek War, the original homeworld was reduced to a bombed out ruin which was of no value to the Daleks until the Movellan Incident in the early 27th century. The Daleks were still based on New Skaro by the beginning of the 28th century, during the Necros Incident. Records were uncertain as to whether Davros based his Imperial Daleks on New Skaro or the original Skaro. In any case, it was this Imperial homeworld which was destroyed during the Hand of Omega Incident in 2960. Following this, the Daleks eventually restored their surviving homeworld to its "former glory" between the 32nd and 38th century. In the wake of the Fourth Dalek War, it was presumed that the Daleks had been driven back to Skaro by the Galactic Federation. Ultimately, a century or so following the conflict, the Dalek Emperor, who may have been the final form of Davros, enacted Operation Human Factor which led to the Dalek Civil War broke out on Skaro, bringing about the Final End of the Dalek race.
