Extermination was the first story in the sixth series of Gallifrey and the twenty-second story over all.

Publisher's summary[]

Gallifrey Fights...

Having infiltrated the Axis, the Daleks have secured access to a myriad alternative realities and, with them, countless Gallifreys... every one with secrets to be plundered.

As her new world falls to the might of the Dalek invasion force, Romana finds herself struggling to keep her friends alive as the Capitol collapses around her.

Against all odds, there may be a way out — back to the Axis and, potentially, back home. But desperate times call for desperate measures and, ultimately, sacrifices...


to be added



  • Narvin has never previously encountered the Daleks.
  • Romana contemptuously refers to the Daleks' creator Davros as "that creature."
  • In the alternative timeline, the Regenerators are unaware of the Daleks' existence.
  • Romana tells Castellan Slyne that the Daleks' eye stalks are their weakest point.
  • Before his death, Andred showed Leela how to operate a staser.
  • After gaining control of the Axis, the Daleks conquered multiple Gallifreys in different alternative timelines.
  • K9 fled to another alternative timeline after the Daleks arrived on the Axis.
  • The Supreme Dalek accompanied the invasion task force to the alternative Gallifrey.


  • This audio's cover notably features the image of a Dalek of the design first introduced by the revived Doctor Who series in 2005, indicating that the events of Gallifrey are approaching the Last Great Time War. This precedes Big Finish's 2015 acquisition of the license to produce audios based on the revived Doctor Who by a year and a half.
