The Wayfinder's Sector Imperialis

The Wayfinder's Sector Imperialis is a large floating district of the world-city that is Terra that is entirely given over to the aristocratic families of the Vrit'enbruk Nobilite. The Wayfinder's Sector Imperialis is home to some of the stateliest palaces the hand of Mankind has ever raised. Almost every Wayfinder House maintains an estate within the Sector Imperialis. By ancient tradition, even those ruins of once-great edifices belonging to disgraced or extinct Houses are left as they were when their last masters departed. Thus, amidst the opulence there can be seen tragic reminders of Wayfinder Houses cast down or lost to the passage of time and war, the skeletal ruins of their once majestic palaces crumbling away beside the still-standing splendor of those of their rivals remaining in existence. 
In many cases, however, Terra is not the center of a Wayfinder House's power and their mansions are maintained there only as a matter of form. The interests of most Houses are spread far and wide across the Imperium, as befits an organisation whose fortunes depend upon their expertise traversing the countless Void routes of the galaxy. It is not uncommon for various Wayfinder Houses to concentrate their resources more in one region of the galaxy than in others, and so most sectors of the Imperium are host to the central holdings of at least one, and possibly several dozen, Wayfinder Houses.
== Palace of the Wayfinders ==
The Navitorus Primus of the Vrit'enbruk Nobilite permanently resides in the Palace of the Wayfinders which dominates the center of the Sector Imperialis. From the moment he or she is installed, the Navitorus Primus never leaves this palace. The staff, soldiery and other retainers of the Palace of the Wayfinders are all drawn from the Navitorus Primus's own Wayfinder House, and are all replaced with each new Navitorus Primus who assumes the office. From this throne on ancient Terra, the Navitorus Primus guides the destiny of the Houses, ensuring their place of power within the galaxy. The chief amongst a Navitorus Primus's servants is the Navitorialis Envoy, who often serves as one of the High Lords of Terra, representing the interests of the Vrit'enbruk Nobilite on the Senatorum Imperialis.
