Following a ploy with the Daleks on 22nd century Earth, the Master travelled with Susan Foreman in his TARDIS to Tersurus, where she believed she killed him. (PROSE: Legacy of the Daleks) According to another account, however, the Master attempted to attack a Time Lord outpost on the planet, and was left disfigured after a confrontation with a future incarnation, as part of a plan to join the Cult of the Heretic. (AUDIO: The Two Masters) In any event, a signal sent to Gallifrey by the Master's TARDIS drew Chancellor Goth to Tersurus, where he found the disfigured body of the Master. (TV: The Deadly Assassin)
Behind the scenes Edit
The Curse of Fatal Death Edit
Tersurus is a setting in the Comic Relief special mini The Curse of Fatal Death, which this wiki does not consider to be a valid source. In the special, Rowan Atkinson's Ninth Doctor meets with the Master on Tersurus to tell him the news that he has plans to marry his companion Emma and retire.
The special also gives details on the natives of Tersurus, the Tersurons. The Doctor explains to Emma that the Tersurons were a kindly, peace-loving race shunned and abhorred by the rest of the universe due to their method of communicating solely through precisely modulated farting. They destroyed themselves after discovering fire. The evolution of this form of communication is briefly explained in PROSE: The Taking of Planet 5.
The Master makes one final attempt to destroy the Doctor and his companion, Emma, by plunging them into the vast, labryrinthian sewers of Terserus. The sewers being so vast and complex, as well as disgusting and treacherous, it takes the Master himself 312 years to escape from them, being repeatedly knocked into the sewers on three separate occasions, requiring the Daleks to regress him back to a more youthful state. This adventure was briefly referenced by Missy in AUDIO: The Bekdel Test.
