Untempered Schism
The Untempered Schism was an opening in the space/time continuum, "a gap in the fabric of reality from which can be seen the whole of the Vortex". (TV: The Sound of Drums) The Schism appeared to consist of an opening into the Vortex, contained in a circular ring. Before the Schism lay a plaque bearing the Seal of Rassilon.
Use in Time Lord initiations
It was used by the Time Lords in an initiation ceremony for children entering the Time Lord Academy. The young Gallifreyans subjected to its terrifying effects would react differently — "Some would be inspired, some would run away, and some would go mad." The Doctor and the Master agreed that the experience was painful. (TV: The End of Time) It was claimed prolonged exposure to the Schism over billions of years gave Time Lords their ability to regenerate and indeed was the primary factor in their evolution. (TV: A Good Man Goes to War).
Initiation of the Master
As a child, during his initiation, the Master gazed into the Time Vortex through the Schism, and saw the raw power of time and space — "That's when the Master first saw eternity." (TV: The Sound of Drums) It was at this moment that the Drumming, a signal sent back through time by the Time Lords in the final hours of the Last Great Time War, (TV: The End of Time) entered the Master's mind and plagued him throughout the rest of his life.
Because some who stared into the Untempered Schism would go mad, many, initially including the Doctor, believed that there was no real drumming in the Master's head, and that staring into the Schism had simply driven him mad.[source needed]
Initiation of the Doctor
The Doctor suggested his eight-year-old self was one of the ones who ran away — indeed, that he never stopped running. (TV: The Sound of Drums) The Doctor suggested he found his experience painful. (TV: The End of Time)
Behind the scenes
- The "time tunnel" effect seen in the Untempered Schism, and reflected in the eyes of the young Master, is the same technique used in the opening title sequence of the Doctor Who TV series from series 1 to the 2009 specials and during certain episodes from 2005 onwards where the TARDIS is shown in flight through the vortex. It was also used at the opening of The Sound of Drums to represent the transit through the space-time continuum with Jack Harkness's vortex manipulator.
