The Prime Eye of Harmony

(aka Rassilon's Star, The Caldera, The Time-Sun)

The Prime Eye of Harmony on Gallifrey

Rassilon's Star was originally a Population III star named Qqaba. Rassilon and Omega used the Hand of Omega to turn this star into a rotating Black Hole. Using Amaranths, transdimensional physics, and Stasis-Halos, Rassilon brought the nucleus of the universe's first Black Hole to Gallifrey. The Eye was stabilized in an eternally dynamic equation against the mass of Gallifrey. This star became known as the Eye of Harmony because it sits outside History and watches the rest of the Universe. The Eye makes up the largest structure on Gallifrey - so large that it needs its own fold in space micro-universe
to contain it.
This chamber is known as the Caldera and is located under the Panopticon (assembly hall) in the Capitol. Rassilon also created the ebonite rod known as the Rod of Rassilon (sometimes translated as "Great Key") which allows a Time Lord physical access to the Power Mast of the Eye of Harmony. The Caldera itself can be accessed via the Vaults found beneath the Capitol. The Security Codes needed to enter the Caldera change every microspan. If a lesser species was to enter the Caldera they would be killed. Indeed, due to density of strands in the Web of Time it is unhealthy for even a Time Lord to stand too close to the Eye.

Within the Event-Horizon of the black hole are a singularity and a universe of antimatter. Outside the Event-Horizon of the spinning star is an area called the Ergosphere. In this area energy that escapes the singularity's gravity is accelerated and amplified to almost infinite levels. Rassilon surrounded the Ergosphere with an iron sphere 10 kilometres in diameter. This sphere was mirrored on the inside. Rassilon allowed a light beam to enter the sphere. This light was amplified by the singularity's Ergosphere, reflected off the mirrored sphere, was amplified again, and so on. Each time the light beam gained energy. A small hole at the top of the sphere releases the amplified light beam. Using transdimensional physics, the Eye was shifted slightly into the future turning it inside out through the 5th dimension. This process is known as singularity eversion and it is done so that the near infinite power of the light beam emerges in a slow controllable osmotic stream. Without the Singularity Eversion the eye would turn into an exploding quasar.

After being converted into Artron Energy, the power is ready for use. Artron energy is measured in units called Omegas. This near magical use of super-radiant scattering allows the Eye of Harmony to provide energy for all of Gallifrey's needs (including time travel). The destabilization of the Eye of Harmony would cause Gallifrey to turn into antimatter, creating a quasar that would destroy a hundred worlds.
