Editing The Master (Doctor Who) (section)

=== Novels ===
The Master's past with the Doctor is explored in ''[[The Dark Path (McIntee novel)|The Dark Path]]'', which reveals that his name before taking the alias of the Master is [[Koschei]], when he encounters the [[Second Doctor]] during their travels. Although initially a somewhat anti-heroic version of the Doctor, willing to murder to save the day but generally still trying to do the right, Koschei turns to evil and becomes the Master after he discovers that his companion and lover Ailla is an undercover agent of the [[Celestial Intervention Agency]] sent to spy on him. During the course of the novel, Ailla is shot and killed.  Koschei, not knowing that she is a Time Lord and will simply regenerate, completes a time-based weapon to benefit the anti-alien efforts of soldiers from Earth's Empire in an attempt to bring her back. The weapon is used to destroy the planet Teriliptus and its inhabitants. When Ailla turns up alive, the knowledge that he has destroyed a planet for nothing, coupled with the revelation of Ailla's betrayal, proves too much. Koschei resolves to bring his own order to the universe at the expense of [[free will]] and becoming its Master. Thanks to the Doctor reprogramming his weapon, Koschei is trapped in a [[black hole]] at the end of the novel, with it being left uncertain how he will escape.<ref>{{cite book |last=McIntee |first=David A. |author-link=David A.

''[[The Face of the Enemy (Doctor Who)|The Face of the Enemy]]'' centres around the Delgado-era Master, but includes a cameo by a Koschei from an alternate timeline (specifically, the timeline the Third Doctor visited in ''[[Inferno (Doctor Who)|Inferno]]'') who never became the Master. This version of Koschei is a loyal Time Lord who was stranded on the alternate Earth after that universe's version of ''[[The Web of Fear]]'' destroyed his TARDIS. He is subsequently captured and forced to work for the fascist rulers, who keep him alive in agony using [[life support]] systems. When the Master, crossing over from the other universe, learns of this, he ends his counterpart's life in a rare moment of compassion.<ref>{{cite book |last=McIntee |first=David A. |author-link=David A.

''[[Last of the Gaderene]]'' by [[Mark Gatiss]] and ''[[Deadly Reunion]]'' by [[Terrance Dicks]] and [[Barry Letts]] are both close homages to the Delgado/Pertwee stories. In ''Last of the Gaderene'', the Master, disguised as Police Inspector Lemaitre, assists an alien race called the Gaderene to invade Earth, starting with a small village.<ref>{{cite book |last=Gatiss |first=Mark |author-link=Mark Gatiss |date=3 January 2000 |title=Last of the Gaderene |title-link=Last of the Gaderene |series=[[Past Doctor Adventures]] |publisher=[[BBC Books]] |isbn=0-563-55587-4 }}</ref> In ''Deadly Reunion'', he attempts to control powerful forces through a cult, but finds himself at the mercy of a godlike alien.<ref>{{cite book |last1=Dicks |first1=Terrance |author-link=Terrance Dicks |last2=Letts |first2=Barry |author-link2=Barry Letts |date=November 2003 |title=Deadly Reunion |title-link=Deadly Reunion |series=[[Past Doctor Adventures]] |publisher=[[BBC Books]] |isbn=0-563-48610-4 }}</ref> The Delgado Master also appears in ''[[Verdigris (novel)|Verdigris]]'' by [[Paul Magrs]], a more parodic take on the Pertwee era. The eponymous [[genie]] spends much of the novel impersonating the Master, who is in fact controlling him: the real Master appears in the novel's epilogue, buying a Chinese [[take-out|takeaway]].<ref>{{cite book |last=Magrs |first=Paul |author-link=Paul Magrs |date=April 2000 |title=Verdigris |series=[[Past Doctor Adventures]] |url=https://archive.org/details/verdigris00paul |publisher=[[BBC Books]] |isbn=0-563-55592-0}}</ref>

The reason the Master is so emaciated when he appears in ''[[The Deadly Assassin]]'' is explored in [[John Peel (writer)|John Peel]]'s novel ''[[Legacy of the Daleks]]'', in which he attempts to capture the Doctor's granddaughter [[Susan Foreman]], resulting in an out-of-sequence encounter with the [[Eighth Doctor]] when the Doctor receives a telepathic cry of distress from Susan and attempts to trace it back to before its origin. The Master is badly burned when she attacks him in self-defence and takes possession of his TARDIS. After Susan escapes, the dying Master is eventually found by Chancellor Goth on the planet Tersurus, which leads directly into the events of ''The Deadly Assassin''.<ref>{{cite book |last=Peel |first=John |author-link=John Peel (writer) |date=April 1998 |title=Legacy of the Daleks |title-link=Legacy of the Daleks |series=[[Eighth Doctor Adventures]] |publisher=[[BBC Books]] |isbn=0-563-40574-0 }}</ref>

The Ainley-era Master appears in the novel ''[[The Quantum Archangel]]'' by [[Craig Hinton]], a direct sequel to ''The Time Monster''. In this novel, he poses as a Serbian businessman called [[Hospodar|Gospodar]] (prompting the [[Sixth Doctor]] to wonder if he's "running out of languages") while attempting to subvert the power of the higher dimensions to turn himself into a god. However, it to be revealed that this plan was actually the result of the machinations of the Chronovore/Eternal hybrid Kronos trying to trick the Master into punishing the Chronovores for his lifetime of imprisonment, with one of the Master's pawns being transformed into the titular Quantum Archangel when she absorbs the higher-dimensional energy as the Master tests his equipment. As the novel concludes, the Master briefly regresses to his crippled and burned form while the Doctor absorbs more of the excess energy to delay the Quantum Archangel on her level, but the story ends with the Master having restored himself to physical health with a boost of the last dregs of higher-dimensional power (although he is apparently subsequently attacked by a group of chronovores).<ref>{{cite book |last=Hinton |first=Craig |author-link=Craig Hinton |date=January 2001 |title=The Quantum Archangel |title-link=The Quantum Archangel |series=[[Past Doctor Adventures]] |publisher=[[BBC Books]] |isbn=0-563-53824-4 }}</ref>

''First Frontier'' shows the Master (apparently the Ainley version) finally acquiring a new body,<ref>{{cite book |last=McIntee |first=David A. |author-link=David A. McIntee |date=September 1994 |title=First Frontier |series=[[Virgin New Adventures]] |url=https://archive.org/details/firstfrontier00mcin |publisher=[[Virgin Books]] |isbn=0-426-20421-2}}</ref> who according to McIntee is based on the cinema persona of [[Basil Rathbone]],{{citation needed|date=April 2015}} using nanites provided by the alien race known as the Tzun in exchange for his help in setting up their 'invasion' of Earth. This incarnation reappears in ''[[Happy Endings (novel)|Happy Endings]]'' by [[Paul Cornell]], Virgin Publishing's celebratory fiftieth [[Virgin New Adventures]] novel, once again trying to restore his ability to regenerate, suggesting that the Tzun nanites failed to sustain him long-term.

Before the end of the [[Virgin Missing Adventures]] series, the Delgado version of the Master appears in the novel ''[[Who Killed Kennedy]]'', depicting him setting up a complex plan to manipulate a journalist to bother UNIT by convincing him that they are part of a corrupt conspiracy.  The novel, while published by Virgin, was not considered part of the Missing Adventures series.

Another version of the Master appears in ''[[The Infinity Doctors]]'' (also by Parkin), where he is known as the Magistrate and is, once again, the Doctor's friend, although when this takes place in continuity is unclear.<ref>{{cite book |last=Parkin |first=Lance |author-link=Lance Parkin |date=22 November 1998 |title=The Infinity Doctors |title-link=The Infinity Doctors |series=[[Past Doctor Adventures]] |publisher=[[BBC Books]] |isbn=0-563-40591-0 }}</ref> Parkin has stated{{Citation needed|date=August 2007}} that the novel can fit into continuity and that its incarnation of the Master is based on [[Richard E. Grant]].

During the [[Faction Paradox]] arc that runs through the Eighth Doctor Adventures, a character known as the War King is featured, which is implied to be a future incarnation of the Master.{{citation needed|date=November 2012}} The character is also referenced in ''[[The Book of the War]]'', published by [[Mad Norwegian Press]] when the ''Faction Paradox'' stories spun off into their own continuity.<ref>{{cite book |date=2002 |editor-last=Miles |editor-first=Lawrence |editor-link=Lawrence Miles |title=The Book of the War |title-link=The Book of the War |series=[[Faction Paradox]] |publisher=[[Mad Norwegian Press]] |isbn=1-57032-905-2 }}</ref> Later Faction Paradox stories confirm the Magistrate is the younger version of the War King, which had been implied in ''[[The Taking of Planet 5]]''.

[[Alastair Reynolds]]' novel ''[[Harvest of Time]]'', published in 2013, features the Roger Delgado incarnation, set after his capture at the end of ''[[The Dæmons]]'' and before he escapes from prison in ''[[The Sea Devils]]''.<ref>{{cite book |last=Reynolds |first=Alastair |author-link=Alastair Reynolds |date=June 2013 |title=Harvest of Time |title-link=Harvest of Time |series=''[[Doctor Who]]'' novels |publisher=[[BBC Books]] |isbn=978-1849904186 }}</ref> In the course of the novel, the Master is nearly erased from history by an ancient race known as the Sild, who have captured multiple incarnations of the Master to create a complex temporal manipulator by linking the Masters in a neural network, but the Doctor and the Master track the Sild to their origin, allowing the Master to take control of the Sild's network and turn it against them before his other selves rebel against his control, forcing him to allow the other Masters to escape.
