The Master claims to hail from a time where paradoxes occur "almost daily", though admits there are no "recognisable days anymore", implying that he came from the Time War. He is working for the CIA, suggesting a setting before he started working against the Time Lords.
At some point in the Time War, the Master regenerated into the body of a small child. ( COMIC: The Organ Grinder )
Being at the centre of the paradox causes the "Child" Master to revert back into his "War" incarnation, erasing himself from the timeline.

Escapades in the Time War [ edit source ]
The Master rescues Lyric from the Time War, but leaves her sister to die. ( AUDIO: The Scaramancer ) He takes Lyric on as a companion; taunting her over her sister's death in order to study her grief. They eventually part ways when they grow bored of each other. ( AUDIO: The Cognition Shift )
The Master swaps bodies with the Eighth Doctor.
The Master and the Doctor are returned to their own bodies. The Master is reunited with Lyric, who now calls herself "the Scaramancer".
The Master is Time Scooped by his next incarnation. He notes that he's spent his whole life fighting a war, but hasn't used a Tissue Compression Eliminator in "a while".
Final contributions to the Time War [ edit source ]
The Master sets up his plan to steal the Anti-Genesis codes by setting up a mental link with his follower Crazlus, whom he asks to gain a position in the Celestial Intervention Agency. ( AUDIO: He Who Wins )
The Master fakes his death to fool the Time Lords, before being revived by Crazlus and stealing the Anti-Genesis codes, leading directly into The Master's Dalek Plan.
Under the guise of "Master Sorvad", the Master takes control of Skaro and Dalek history. Ending leads directly into Shockwave.
Ending leads directly into He Who Wins.
The Master recalls the events of Day of the Master. Having conquered the universe, the Master is convinced that his Dalek allies will betray him by an exiled Master from a parallel universe. Working with the Dalek Time Strategist, the Master contacts himself shortly after he set up the mental link with Crazlus, whom he has exterminated, reverting the timeline to before From the Flames. In an attempt to escape the Daleks, the Master sets his TARDIS to dematerialise to a random location, though he is separated from it via a transmat beam, leading directly into Beneath the Viscoid.
After retrieving his TARDIS from Gardezza, the Master is summoned to Gallifrey.
Follows on from Beneath the Viscoid, with the Master arriving on Gallifrey, and referring to having gone to "a great deal of trouble" to recover his TARDIS. Once he throws Leela into the Time Vortex after a mission to recover vital information that might end the Time War, the Master decides to head for Arcking based on intelligence from Finnian Valentine, leading directly into The Good Master.
The Master begins traveling with Cole Jarnish after meeting him on Arcking.
The Master has begun using Cole in his scheme to end the Time War by allowing Cole to meddle in time as much as possible in order to create more energy from the paradox that he has become.
The Master kills Cole in order to power up the Heavenly Paradigm, a weapon that can end the Time War, only for his use of it to backfire. After watching the Dalek Emperor take control of the Cruciform, the Master flees from the War and the Time Lords, going to the end of the universe, where he uses his Chameleon Arch to turn himself into a human baby. He has his TARDIS dematerialise to parts unknown after he exits it.
Hiding at the end of the universe as a human scientist named " Yana", the Master finds himself working on the Utopia Project on Malcassairo with Chantho. ( TV: Utopia )
Upon the arrival of the Tenth Doctor, Jack Harkness and Martha Jones, Yana is spurred to open the Chameleon Arch and return to his true identity. The Master is shot by Chantho when he kills her, but he is able to commandeer the Doctor's TARDIS before he regenerates.
