Deviations from televised story

 * Ian slaps Barbara when she gets hysterical.
 * The Voord are identified as a frog-like subspecies with bullet-shaped heads, lacking their distinctive inky black helmets.
 * The warrior that stalks Susan around the perimeter of the marble City is described as a "Class 1 Voord Assault Trooper", programmed to kill enemies on sight, implying that part of the Voord assault force may be bionic or robotic in nature.
 * In the TV serial, it's never quite clear what triggers the outer city walls' ability to rotate. The novelisation clarifies this by stating that there are sections of the marble that are pressure sensitive.
 * Yartek is said to have developed a technological immuniser to the influence of the Conscience, distributing it among his followers, rather than the unexplained resistance of the televised story.
 * Ian is still on the rope bridge when Vasor severs it with his knife.
 * Sabetha and Altos briefly visit Ian during his incarceration in Millennius.
 * Aydon attempts to flee the Court when identified by Sabetha before he makes his protestations heard. It's vice versa in the televised version. The shot that kills him is a "spurt of blue flame" and Susan sees that those closest to the body as it falls are Tarron, Eyson and Larn.
 * When the false key is inserted into the apparatus of the Conscience, there is a red glow at the centre, growing in intensity, until finally spokes of purple light radiate outwards along the delicate metal connectors. The entire structure blazes like a giant catherine wheel and self-combusts. The explosion vaporises Yartek and the entire Archive Room of the complex in less than a millionth of a second.

Writing and publishing notes

 * This title was Philip Hinchcliffe's last contribution to the range and his sole novelisation of a serial he did not produce.
 * With no photographs for reference, cover artist David McAllister decided to try something different and feature no people on the cover.
 * Then producer John Nathan-Turner's insistent critique of the cover artwork - namely that the TARDIS itself is blue, not grey and the light atop it white, not red - went unheeded. The unaltered image was used for publication.

Continuity

 * The Voord's origins here as genetically-engineered animals conflict with other sources that position them as early ancestors to the Cybermen. (COMIC: The World Shapers)
