House Lineacrux

House Lineacrux was an Oldblood House on the Homeworld, and often considered one of the more archetypical Houses: a producer of old, ponderous men, obsessed with the rules of non-intervention and the Protocols of the Great Houses. (PROSE: The Book of the War) However, they produced at least one renegade, the Lady Cortalianesquertal vel-Lineacrux. (PROSE: Going Once, Going Twice)

During the War in Heaven House Lineacrux was content to stand in the background, acting as advisors to the more active Newblood Houses, quietly shaping the perspective of the younger Houses' views on the Homeworld and its place in history. Their desire to avoid the limelight went so far as letting other Houses taking responsibility for crypto-forming the Nine Homeworlds, even though it was originally a House Lineacrux idea.

They wore yellow-gold robes (PROSE: The Brakespeare Voyage) like the Time Lords who sent the Second Doctor and Jamie to investigate Space Station J7. (PROSE: The Two Doctors)
