The Prydonian or Prydon Chapter (PROSE: Lungbarrow) was the most powerful of the original Chapters on Gallifrey. It produced devious Time Lords, and more than a few renegades, amongst them the Doctor and the Master.
Rassilon was the Grand Master of the Prydonian Chapter even before the Gallifreyans became Time Lords. (COMIC: Star Death) At the time, the Chapter was attacked by the Order of the Black Sun in its Question Hall. (COMIC: 4-D War)
Subsequently, more Time Lords from this chapter assumed the office of Lord President than all others put together. (TV: The Deadly Assassin) By the time of the Valeyard's trial, there had not been a non-Prydonian president for centuries. (AUDIO: Trial of the Valeyard) This Chapter greatly opposed the creation of the N-Forms. (PROSE: Damaged Goods)
The House of Blyledge had senior members as part of this chapter. (PROSE: Cat's Cradle: Time's Crucible, PROSE: Cold Fusion) The Doctor and their Cousins belonged to the House of Lungbarrow. (PROSE: Lungbarrow)
Each Chapter had its own colours. The Prydonians had scarlet and orange ceremonial robes and were represented by an abstract symbol known as the Prydonian Seal. (TV: The Deadly Assassin, The Five Doctors) Prydonians were noted for their cunning. One could not take their eyes off them for a second. (AUDIO: Spring) Whilst they were known to be devious, it was believed that they were quite honest about this trait amongst their Chapter. (PROSE: Damaged Goods) Members of this chapter swore "Prydonian vows"; it was thought that once a Prydonian had forsworn those vows and their "birthright" as a Prydonian, they would be especially dangerous. (TV: The Deadly Assassin)
Chancellor Djarshar had great disdain for the college, saying that the institution was comprised of "renegades, fugitives, lunatics and ingrates". He went on to suggest that Prydonians "[thought] Gallifrey owed [them] everything." (PROSE: The Ancestor Cell)
Notable members Edit
The Eighth Doctor clearly remembered being a Prydonian on Gallifrey in his youth. (PROSE: The Face-Eater, The Eight Doctors) The Fourth Doctor stole Prydonian robes to wear when he visited Gallifrey on a formal occasion, and he was acknowledged as Prydonian by Borusa and others. (TV: The Deadly Assassin) As Clara Oswald stated to the Cybermen, his Prydonian privileges were revoked after the First Doctor's theft of a TARDIS and subsequent departure from Gallifrey. (TV: Death in Heaven) The Twelfth Doctor swore an oath as a Time Lord of the Prydonian Chapter. (TV: Extremis)
