A type of time energy produced from the synthesis of the mystical Gallifreyan relic, the Holem and frequencies of the Stillness at the center of the Time Vortex. The reverberations of this energy bombard the basic make-up of anyone of the Time Lord race, modifying their DNA. It activates a complete cellular breakdown of Time Lord physiology and a painful regression through all of their previous regeneration cycles, back to a point in the body’s original state; an actual reversal of the body’s age and the normal effects of time in what is called Retrocyclic regeneration.
