Prydonian Chapter

The Prydonian Chapter (also known as the Prydon Chapter) was known to produce devious Time Lords, and more than a few renegades, amongst them the Doctor and the Master.

History
The Prydonian Chapter was named after the Hero known as Prydonius. (PROSE: Cat's Cradle: Time's Crucible)

No less a personage than Rassilon, co-founder of the Time Lords, headed the Chapter before the creation of the Time Lords themselves. (COMIC: Star Death)

Subsequently, more Time Lords from this chapter assumed the office of Lord President than all others put together. (TV: The Deadly Assassin) 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 First Doctor and his Cousins belonged to the House of Lungbarrow (PROSE: Lungbarrow)

Characteristics
Each Chapter had its own colours. The Prydonians had scarlet and orange ceremonial robes. (TV: The Deadly Assassin) The Prydonians had 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 his "birthright" as a Prydonian, he would be especially dangerous. (TV: The Deadly Assassin)

Behind the scenes
The relationship between the Prydonian Chapter and the Prydonian Academy is unclear because Paul Cornell, inventor of the Prydonian Academy, never directly specified a relationship, aside from mentioning that the students of the Prydonian Academy wore scarlet robes. This can no longer be seen as particular evidence, in light of the fact that The End of Time had all Time Lords dressed in scarlet. Prydonian Chapter
