Each Chapter is organized into several Houses. Each House uses a different genetic core to loom its cousins. This means that members of each house have minor variations in abilities. Gallifreyans who become Investigators for the CIA loose all rank and connection to their colleges. Under the Worshipful and Ancient Law of Gallifrey, a member of any House can give up the protection of their House and become the Kithriarch of a new House with a new Chapterhouse and Loom. The founder of a new House carries the title Grandfather. A new loom probably takes over 11 years to produce its first loomling. A Renegade Time Lord traditionally renounces his name and his house.
Of the many Houses there are five or six Founding Houses that date all the way back to the Dark Time. These Houses command significantly more respect than later ones.
The House of Blyledge was ancient even before the time of Rassilon. Blyledge is one of the senior houses in the Prydon Chapter of Glorious Gallifrey. The House of Blyledge is an angular small dark building that is older than the hill it sits on. It has a walled garden of silver trees in its center and is within visual sight of the Capitol. Family members often wear blue clothes and thus the House might be a member of the the Cerulean Chapter.
One of the Houses that predates the Intuitive Revolution. Some of its family were members of the Sisterhood.
The least active of the Founding Houses, known only for their expertise in Gallifreyan history and laws.

In fact the Lineacrux cousins at some of the most powerful and influential members of Gallifreyan society. Their decrepit appearance is merely an act designed to lull others into ignoring them. They observe and (when consulted) offer their opinion in almost all gatherings of Gallifreyan society.
The oldblood houses are the Founding houses plus the houses created by Rassilon after the Intuitive Revolution.
The cousins of this house are Gallifrey's only scientific fundamentalists. They place great faith reason and logic as the solution to all problems and shun emotion.

This House is located on the edge of the civilized portion of Gallifrey next to a mountain range. Its original Family left during the first Diaspora leaving only a line of caretakers to watch after the House. Millions of years later Morbius chose it as the Headquarters for the Order of the Weal and made one of the caretakers, Chatelaine Thessalia, head of the organization.

Nechronomancers don't believe in the passage of time and don't acknowledge their gender or their names. They've deleted most of the records of their House and are viewed as pariahs among Time Lord society. They are capable altering time states in ways that would be impossible for any other Time Lord. During the War these deep engineers collected Highest Entropy Matter (HEM) from dead time states (where the universe had reached thermal equilibrium and history/time has ceased to flow).
