Continuity
- The time travel technology the Dalek demands from the Doctor is a time ring, a device last seen in the Fourth Doctor serial, Genesis of the Daleks. In the novel, the Doctor has kept the ring in an old chest, in the TARDIS. It is unknown if this is the same one as Genesis, but it is generally accepted (due to its age, and the fact the Doctor has kept it from a previous adventure) that it is the same one (even though that time ring was apparently retrieved by the Time Lords shortly after returning the Doctor and his companions to the Nerva station in Revenge of the Cybermen).
- The concept of a Dalek factor originated in the Second Doctor serial The Evil of the Daleks.
- Unlike the previous Tenth Doctor novels, the exact placement of this story in the Tenth Doctor's chronology is uncertain. The Doctor Who Reference Guide places it between the episodes "Tooth and Claw" and "School Reunion" but it could also take place at any time between "The Age of Steel" and "Army of Ghosts".
- The idea of a Human-Dalek fusion was later reused in "Daleks in Manhattan". Whether the Human-Dalek hybrids from this book and the episode are related is unclear. The idea reappeared in "Asylum of the Daleks".

Famous quotes containing the word continuity:

—Ralph Waldo Emerson (1803–1882)
“The dialectic between change and continuity is a painful but deeply instructive one, in personal life as in the life of a people. To “see the light” too often has meant rejecting the treasures found in darkness.”
—Adrienne Rich (b. 1929)
“Continuous eloquence wearies.... Grandeur must be abandoned to be appreciated. Continuity in everything is unpleasant. Cold is agreeable, that we may get warm.”
