Narratively, the story was remarkable for the fact that it brought together the Sixth and Seventh Doctors, Davros, Abslom Daak and Bernice Summerfield. It therefore relied heavily on established continuity, and demanded the reader have a fair grasp of Daak's backstory, which had been printed in the magazine ten years earlier. More significantly, the story acted as a prequel to Remembrance of the Daleks, branching Davros's story between Revelation and Remembrance.
