Rassilon is a fictional character in the British science fiction television series Doctor Who. In the backstory of the programme, he was the founder of Time Lord society on the planet Gallifrey and its first leader, as Lord High President. After the original television series ended in 1989, Rassilon's character and history were developed in books and other media.
Within the universe of the television series, there are many contradictory legends about Rassilon. It is known that he developed the technology for time travel that made his people lords of time in the distant past together with his colleague Omega. Omega, a stellar engineer, was presumed killed by the supernova that created the black hole later known as the Eye of Harmony, and Rassilon harnessed the nucleus of the black hole to provide the energy that powers time travel. Rassilon then took control of Gallifrey and became the first and, to date, only Lord High President, his successors taking the title Lord President. The official history is that he was a benevolent ruler who ruled his people wisely. However, there are other accounts which paint Rassilon as an opportunistic, ambitious and cruel dictator who seized power in the wake of his friend's death (for which some suggest he may have been deliberately responsible), and ready to go take drastic measures to protect his people, nearly destroying all of time once.
I spent 9 months I've been thinking about absence and progression
Under this, under this tetra-coloured plane
And now we're finally fading fast
On broken wings and shattered glass
Depart from daylight, lay awake at night
This is isn't what it's like to die
This isn't what it's like to die
Again we're finally fading fast
On broken wings and shattered glass
Depart from daylight, lay awake at night
This is isn't what it's like to die
This isn't what it's like to die
You could have been the sweetest lie I ever tasted
That I can remember
And I know this isn't what it's like to die
Just realizing if I ever learned from the act of flight
Then I'd live through the process of descension
And I'll never come back here again
And I'll never come back here screaming
"For you I bleed life, for you I follow this tetra coloured sky"
And now we're finally fading fast
On broken wings and shattered glass
Depart from daylight, lay awake at night
