Navigator's Quarter

From Lexicanum

The Navigator's Quarter is a vast district situated on Terra, where the more powerful of the Navigator Houses have their literal family houses. These gigantic palaces stretch over large areas, and are formed of a labyrinth of ornate buildings, surrounded by opulent estates. Such is the grandeur of these places they are said to contain collections of sacred relics to match anything possessed by the Ecclesiarchy.

At the centre of the Navigator's Quarter is the Palace of the Navigators, from where the Paternova rules. Following his ascension, the Paternova never leaves the Palace. This massive building is always staffed by members drawn from the Paternova's own house.

Beneath the Navigator's Quarter is a far darker world known as the Vaults. These vast labyrinths stretch downwards towards the planetary core and are the sometime home to the strange mutated ancients of the Houses.
