Time stream
The time stream was the pathway for the movement of time, usually in relation to individual peoples or planets.
Characteristics
The term "time stream" was used interchangeably with other terminology such as timeline, (AUDIO: Reborn) time track, (AUDIO: Disassembled) parallel universe, and reality. (AUDIO: Forever)
Time streams formed possible futures, as the sigil ring allowed Ruath to change time streams and visit the future Earth ruled by Haemovores. (PROSE: Goth Opera)
The Grey Man plucked the Doctor's TARDIS from the time streams, meaning that the Time Vortex was composed of time streams in addition to time winds. (PROSE: Falls the Shadow) Nyssa explained that the Fifth Doctor travelled the time streams, in addition to moving from planet to planet. (AUDIO: Hexagora)
When concerned about changing history and erasing themselves, the Monk informed Vicki Pallister and Steven Taylor that they were safe as long as they stayed away from their native time streams, meaning they existed as temporal anomalies. (AUDIO: The Secret History)
Individuals
Professor Chronotis' TARDIS could interfere with an individual's time stream. (HOMEVID: Shada, WC: Shada, AUDIO: Shada)
When the Timewyrm appeared in 1981 Great Britain, it stated the timestream was in flux before becoming trapped in puterspace by the Seventh Doctor. (COMIC: The Last Word)
The Doctor
The Second Doctor wouldn't risk re-entering the time stream with the time rotor dismantled. (PROSE: The Nameless City)
At one point when the Third Doctor was attempting to repair his TARDIS, he saw a brief appearance of different versions of himself and Jo Grant, and when they disappeared he told Jo they had gone "back into their own time stream". (TV: Day of the Daleks)
The Seventh Doctor, when considering whether to let Kadiatu Lethbridge-Stewart discover time travel in the 22nd century or not, thought his interference could do things to the timestream that "even a Dalek would think twice about". (PROSE: Transit)
While awaiting his death at Lake Silencio, the Eleventh Doctor had the Teselecta send letters to Amy Pond and Rory Williams, River Song, Canton Everett Delaware III, and a younger version of himself. He explained that to deliver the messages himself, it would involve crossing his own time stream, "best not", he remarked. (TV: The Wedding of River Song)
The Doctor's time stream appeared as an open wound in the fabric of reality inside the ruins of the Doctor's TARDIS in the future on Trenzalore, where the Doctor was buried. The Great Intelligence, in the form of Walter Simeon, arrived on Trenzalore, accompanied by faceless humanoids called the Whisper Men, whom he used to bring several of the Eleventh Doctor's friends there to draw him out so he could invade his time stream, turning all of his victories into defeats and having his ultimate revenge. He did so by directly entering his time stream inside the ruined future TARDIS. However, this plan was foiled by Clara Oswald, who followed the Great Intelligence through the wound. Just as he was, she was ripped into countless versions of herself throughout history and saved various incarnations of the Doctor countless times. The original Clara then found herself in a wasteland inhabited by the various Doctors. However the Eleventh Doctor entered the time stream and was able to extract her, though she saw an unknown incarnation. (TV: The Name of the Doctor)
Species
Time Lords
The Second Doctor stated that the Time Lords were responsible for placing and maintaining the time streams, and without them, countless millions of planets would die. (PROSE: The Nameless City)
The Time Lords revisited their own time stream to rewrite their laws in an attempt to trap the Valeyard. (AUDIO: Trial of the Valeyard) When in 1967 Russia, a Time Lord informed the Seventh Doctor that they had eased his arrival into the time stream. (AUDIO: Thin Ice)
Others
The inhabitants of an unnamed planet were in a different time stream from the rest of the universe. When the First Doctor and Ian Chesterton visited the planet, a few minutes passed for them, but the inhabitants lived through their entire civilisation from their rise and fall. (AUDIO: Rise and Fall)
The Guardians of Time were able to "insert" themselves into the time stream, where upon they either took over or created the personas of powerful individuals in history. (AUDIO: The Destroyer of Delights)
The Graxnix were removed from the time stream by the Tenth Doctor, trapping them between seconds. (COMIC: Hotel Historia)
The Two Streams Facility of Apalapucia used time streams (which was the source of the name). Apalapucians with the Chen-7 plague were kept in the facility in different time streams, allowing them to live out their whole lives in 1 day. This also meant that each patient was kept isolated in a different time stream, but in the same place. (TV: The Girl Who Waited)
Planets
The Third Doctor's encounter with the Silurians was a crucial nexus point in Earth's time stream. (COMIC: Final Genesis)
