|The Eye of Harmony|
|Type:||Black hole power source|
|Place of origin:||A star system|
The Eye of Harmony, also known as Rassilon's Star, was a power source for the Time Lords. It was created by suspending time around an exploding star in the act of becoming a black hole, harnessing the potential energy of a collapse that would never occur. According to the Eleventh Doctor, you would "rip the star from its orbit, [and] suspend it in a permanent state of decay." (TV: Journey to the Centre of the TARDIS)
- The passage, in full, implies that the Eye of Harmony may refer not to the black hole but the singularity contained within it.
In the Panopticon Edit
In the time of the Fourth Doctor, the Eye of Harmony lay secretly under the floor in the centre of the Panopticon. The Time Lords had forgotten its location. Some believed it to be mythical or no longer in existence. (TV: The Deadly Assassin)
The Rod and the Sash of Rassilon Edit
The ancient artefacts ceremonially given to the Lord Presidents had a practical function to do with the Eye. The Rod of Rassilon opened the floor of the Panopticon like a key, allowing a black hexagonal obelisk to rise from the floor. This contained the Eye of Harmony. The Sash of Rassilon, also given to the President, supposedly served as means of protecting the wearer against the forces of a black hole. The practical functions of the Rod and the Sash and the true nature of the Eye of Harmony remained unknown to most on Gallifrey. (TV: The Deadly Assassin)
Attempt to open the Eye Edit
The Fourth Doctor deduced the true use of the artefacts by interpreting enigmatic passages in The Book of the Old Time. He also realised that the name, the Eye of Harmony, symbolically described a black hole contained and balanced against the mass of the planet Gallifrey by Rassilon's engineering. The Master had also separately come to the same conclusion. He deduced that the Sash of Rassilon would give him immunity to the forces unleashed by the Eye if opened (it didn't, due to being damaged by the time he used it). If it had opened, the Eye of Harmony would have functioned as a normal black hole and destroyed Gallifrey and also the Master, who had hoped it would trigger a new cycle of regenerations for him. (TV: The Deadly Assassin)
- Omega also used a black hole in order to enable the Gallifreyans to acquire the power of time travel.
Sontaran invasion Edit
When the Sontarans invaded Gallifrey, their leader, Stor, wished to destroy the Eye. They hid their attack by having the Vardans front it. After the Vardans were defeated by the Fourth Doctor, the Sontarans attacked. They were prevented from destroying the Eye when the Doctor defeated them. (TV: The Invasion of Time)
Dalek invasion Edit
When the Daleks unleashed the Apocalypse Element on the Seriphia Galaxy, the Sixth Doctor and Romana attempted to use the power of the Eye to contain it, but it was insufficent. The Daleks on Gallifrey added their own mental energy to the Eye, which did contain the Element and created a new galaxy for them to transform into their new empire. During this incident the Doctor reprogrammed Gallifrey's security systems so that the Eye could only be opened by a human retina pattern. (AUDIO: The Apocalypse Element)
Inside the Doctor's TARDIS Edit
An aspect of the Eye of Harmony existed within the Doctor's TARDIS during his seventh and eighth incarnation and after the destruction of Gallifrey during his eleventh incarnation. (TV: Doctor Who, Journey to the Centre of the TARDIS)
The Eye of Harmony was said to be the TARDIS's primary power source. The Eye responded to a physical linking device. The particular structure of a human eye had the effect of opening it. Leaving the TARDIS's Eye open for too long would result in space-time distortion. (TV: Doctor Who)
The Eleventh Doctor, Clara Oswin Oswald, Tricky and Gregor Van Baalen once came across the Eye of Harmony when trapped inside the TARDIS. At that point, the Eye had the appearance of a star, one the Doctor claimed was constantly on the verge of becoming a black hole. (TV: Journey to the Centre of the TARDIS)
Dalek Eye of Harmony Edit
After accumulating information from the Library on Kar-Charrat (AUDIO: The Genocide Machine) and their previous invasion of Gallifrey, (AUDIO: The Apocalypse Element) the Dalek Empire developed the use of harmonic energy derived from their own Eye of Harmony, based on that of the Time Lords. Several adjustments were made through the use of temporal barrier technology used on Kar-Charrat. (AUDIO: The Time of the Daleks)
Behind the scenes Edit
No explanation of how the Eye of Harmony could exist in two places at once exists on-screen.
