Warmonger is a BBC Books original novel written by Terrance Dicks and based on the long-running British science fiction television series Doctor Who.

When they arrive, the hospice's advisor, the Reverend Mother Maren (of the Sisterhood of the Flame) convinces Solon to reattach Peri's arm, which he does successfully.

The head of security, Commander Aylmer Hawken tries to stop the Doctor leaving, but Maren convinces him not to, as she is wary of Time Lords.

She leaves the room, but Solon notices Peri's interference and injects her with a poison, but tells The Doctor that her body is rejecting the arm, and she needs the Sisterhood's elixir of life.

The Time Lord President Saran and Borusa refuse to become directly involved, but order the Doctor to unite the largest empires in the galaxy into one army to defeat Morbius.

The Time lords send him Ensign Vidal, a Gallifreyan, to act as his advisor, a flagship and the title of Supreme Coordinator of the Alliance.

The Doctor leads his army into a ground battle, but Maren initially refuses help in defending the elixir of life but eventually accepts.

The hospice is abandoned, the Sisterhood retreat to their temple and Solon resumes his experiments until, years later, the Fourth Doctor and Sarah Jane Smith arrive on Karn.
