Doctor Who Timewyrm Apocalypse by Nigel Robinson

The source material provides extensive excerpts from the science fiction novel, Doctor Who: Timewyrm: Apocalypse, which is identified as the third book in the Timewyrm tetralogy from the New Adventures series. The narrative focuses on the Seventh Doctor and his companion Ace as they arrive on the planet Kirith, where the population is deceptively maintained by the mysterious Panjistri residing on Kandasi Island. A major plot point involves the Panjistri's attempt to halt the Second Law of Thermodynamics and the universe's impending collapse by creating an omnipotent entity called the God machine or Omega Point, utilizing captured lifeforms and seeking to assimilate Ace's aggression. The excerpts detail the Doctor's investigation, the rediscovery of forgotten memories by the Kirithons Raphael and Miril, and the eventual confrontation with the Grand Matriarch, who is revealed to be Lilith, a young girl the Doctor unknowingly infected with the Timewyrm five thousand years prior during his first regeneration. The accompanying editorial note confirms the book's author, Nigel Robinson, and places the novel within the history of Doctor Who publications.
