Prydonian Chapter
From Tardis Wiki, the free Doctor Who reference
The Prydonian Chapter (also known as the Prydon Chapter) was known to produce devious Time Lords, and more than a few renegades.
More Time Lords from this chapter have assumed the office of Lord President than all others put together. They wore scarlet and orange ceremonial robes (DW: The Deadly Assassin). The Prydonian Academy was located some distance up Mount Cadon. (NA: Timewyrm: Revelation)
