Eye of Harmony - The nucleus of
a black hole that was captured by Time Lord Rassilon and
sealed at the center of the planet Gallifrey on the British
sci-fi series DOCTOR WHO/BBC/1963-89.
Introduced in episode No. 14 "The Deadly Assassin," The Eye
of Harmony ("All the power of the Time Lords devolves from
it.") was the product of combined research of two solar
engineers, Omega and Rassilon who wanted to master time and
space and thus create a time travel craft that could moves
effortlessly through the time continuum.
Omega planned on harnessing the energy needed from the
explosion of sun gone nova. His mission succeeded but Omega
was sucked into a parallel universe, never to return.
Using the knowledge gained by Omega's experiments Rassilon
searched the Veil Nebula for the nucleus of a black hole (the
"Eye of Harmony"), collapsed by Omega to harness the raw
energy needed to conquer time.
According to the "Book of the Old Time":
The Eye of Harmony was encased into a hexagonal, monolithic
structure ("Rassilon stabilized all the elements of a black
hole and set them in an eternally dynamic equation against
the mass of the planet.") and installed it into the
Panopticon (circular ceremonial room in the Capital).
"And Rassilon journeyed into the black void with a great
fleet. Within the void no light would shine and nothing of
that outer nature continue in being except that which
existed within the Sash of Rassilon. Now Rassilon found the
Eye of Harmony, which balances all things that they may
neither flux nor wither nor change their state in any
measure; and he caused the Eye to be brought to the world of
Gallifrey, wherein he sealed this beneficence with the Great
Key. Then the people rejoiced."

To control the immense power source three items were
