Transduction barriers were Time Lord protective shields surrounding Gallifrey. These barriers could also be raised around Time Lord space stations, and TARDISes were normally unable to pass through them. (AUDIO: Trial of the Valeyard) Transduction was a method of teleportation used by the Time Lords. (TV: The Deadly Assassin [+]Loading...["The Deadly Assassin (TV story)"])
Nature[[edit] | [edit source]]
It took the disciples of Omega four generations to install the barriers, which were powered by the Eye of Harmony. They kept Gallifrey slightly out of phase with the rest of the universe, protecting the world from invasion by expelling anything foreign to Gallifrey, normally destroying the invasive force. There were at least five levels of intensity to the barrier. (AUDIO: Renaissance)
According to another account, there were four barriers. The First Barrier was a force field that could tear matter apart at a sub-atomic level. The Second Barrier was made of ideas, and refused to let anything pass because it didn't believe it was possible. The Third Barrier used reflection to counter any approach with an equal and opposite idea. The Fourth Barrier of Stubborn Philosophy refused to believe in the existence of any alien craft and would reiterate this until the enemy gave up. (PROSE: Doctor Who and the Krikkitmen)
The transduction barriers around Gallifrey were described to be a ten-dimensional defence field that separated the continuity and history of Gallifrey's space from the rest of the universe by locating it in a micro-universe outside of time. (PROSE: The Quantum Archangel)
History[[edit] | [edit source]]
Rassilon invented the transduction barriers. He was known in his time as one of the greatest force-field engineers in the universe. (PROSE: The Scrolls of Rassilon)
The Doctor's TARDIS was able to slip through the transduction barrier when the First Doctor stole it; he theorised that this was because the ship was deregistered. (AUDIO: The Beginning) An enquiry by the Time Lords later found that the barrier had been disabled before the capsule was taken, with the associated fault locator having been tampered with to prevent the malfunction registering. (PROSE: "Missing TARDIS")
After the Fourth Doctor defeated the Decayed Master, Borusa ordered that the "transduction barriers" be raised so that the Doctor's TARDIS (which had previously been transducted) could leave. (TV: The Deadly Assassin [+]Loading...["The Deadly Assassin (TV story)"])
The barrier was deactivated by K9 Mark I on the orders of the Fourth Doctor, and the Doctor put a hole in the quantum force field above the Citadel. This allowed the Vardans and Sontarans to invade Gallifrey. (TV: The Invasion of Time)
Using Gallifreyan technology from the First Great War TARDIS, the Vast and Terrible Krikkit Fleet was able to simply switch the transduction barriers off. Romana diverted the energy from the barriers to the planetary rotation, moving Gallifrey out of the way. (PROSE: Doctor Who and the Krikkitmen)
One TARDIS did break through, but had to jettison nine tenths of its interior, and most of its circuits fused while its recall circuit burned away, leaving only the telepathic circuits functioning. (AUDIO: Prisoners of Fate)
A squad of Daleks which infiltrated Gallifrey lowered the transduction barrier, allowing them access to Gallifrey to invade. (AUDIO: The Apocalypse Element)
The Time Lord's vault on Tersurus was protected by an outdated transduction barrier which the Reborn Master was able to break through using Goth's TARDIS. Before the barrier could be updated and the break-in retroactively undone, the Master killed the vault operators. (AUDIO: Dominion)
The Eighth Doctor breached the transduction barriers to land the TARDIS outside Madame President Romana II's presidential palace. (WC: Shada) The War Doctor did it again during the Last Great Time War to catch the Time Lords' attention about his return to his home planet. (PROSE: Engines of War)
As he tracked the origin of a mysterious white energy that was consuming space, the Eleventh Doctor sailed down a micro-scale dimensional conduit, emerging on ancient Gallifrey, Knowing that this was supposed to be impossible, he suspected that the conduit was what had allowed his TARDIS to bypass the transduction barriers. (COMIC: The Lost Dimension)
The transduction barrier was still in effect following Gallifrey's relocation at the end of the Time War. Finding himself unable to get through it, and with no answer from the High Council, the Twelfth Doctor visited Karn to use the Sisterhood of Karn's secret door to the Capitol. (COMIC: Supremacy of the Cybermen)
Other information[[edit] | [edit source]]
Anti-time was unable to pass through the transduction barriers. (AUDIO: Neverland)
Bennus noted that none of Gallifrey's defences, including the transduction barrier, would be able to withstand the impact of the Thousand Worlds which the Daleks planned to forcibly crash into Gallifrey at fifty times the speed of light. (AUDIO: The Heart of the Battle)
Alternate timelines[[edit] | [edit source]]
In one alternate timeline, the Knights of Velyshaa breached the barrier and invaded Gallifrey. (AUDIO: The Sirens of Time)
In another reality, the transduction barrier had been modified by Rassilon after he had been infected by the Great Vampires. The barrier obscured the skies of Gallifrey and prevented sunlight reaching the planet. They were eventually deactivated using the remains of the Great Key of Rassilon, destroying the Vampires. (AUDIO: Annihilation)
Non-Gallifreyan barriers[[edit] | [edit source]]
During the Last Great Time War, Falkus was protected by a transduction barrier. (AUDIO: A Genius for War)
