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. (NA: 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. (DWM: Star Death)

Subsequently, more Time Lords from this chapter assumed the office of Lord President than all others put together. (DW: The Deadly Assassin) This Chapter greatly opposed the creation of the N-Forms. (NA: Damaged Goods)

The House of Blyledge had senior members as part of this chapter. (NA: Cat's Cradle: Time's Crucible, MA: Cold Fusion) The First Doctor and his Cousins belonged to the House of Lungbarrow (NA: Lungbarrow)

Characteristics
Each Chapter had its own colours. The Prydonians had scarlet and orange ceremonial robes. (DW: The Deadly Assassin) The Prydonians had an abstract symbol known as the Prydonian Seal. (DW: The Five Doctors) Prydonians were noted for their cunning. One could not take their eyes off them for a second. (BFA: Circular Time) Whilst they were known to be devious, it was believed that they were quite honest about this trait amongst their Chapter. (NA: Damaged Goods)
