Face of Rassilon

"It was like the Spear of Longinus to the Time Lords. A relic of such power that he who wore it would have limitless power, but a price would have to be paid." - The Doctor

The Face of Rassilon was a mysterious item from way back into the early stages of Time Lord history. It was spoken in legend to be the most powerful object in the entire universe, holding a small Higgs boson within it - granting some powers of creation. However, whoever had created it, gave it a more secretive purpose, as it held the very biological code, memories and intellect of the Time Lord it is named after and anyone who wears it will not only have the power of Rassilon - they will become Rassilon.
