Editing Aprior Sector (section)

==Worlds of the Aprior Sector==

The Aprior System became prosperous under the Knights' guidance, and with that prosperity came growth, and soon, the Apriori were ready to colonize other nearby systems.  However, the Warp was too turbulent for jumps longer than a dozen light-years or so.  As such, contact with the Imperium would be nonexistent, and communication between systems would be risky at best.  It was decided that each system would have to be entirely self-sufficient, just as Aprior itself was, and so the Apriori created a document listing their best practices, a sort of blueprint for creating other systems like theirs.  After a few other systems had been colonized along this pattern, they formalized it into the Aprior Sector Charter.  The Charter also created a Sector-level ruling body, the Aprior Sector Legislative Assembly, in order to coordinate trade and mutual defense.  
By now, the Sector has over four hundred inhabited worlds; each one is different, but they are all held to the Charter's standards of economic viability, self-sufficiency, and protection of the rights of citizens.  Due to the aforementioned limitations on Warp jumps during the Aprior expansion period the "density" of colonized planets and systems in each given sector is a little higher than the Imperial norm, more analogous to the expansion of Tau Septs.

===Aprior Subsector===

Since the [[Knights Inductor]] rule the Aprior System, and they led the colony ships that settled other worlds, they have the legal option to directly rule every world in the Aprior Sector.  Outside of dire emergencies, they limit their rule to the Aprior Subsector, the first few systems to be settled.

====Aprior System====

The Aprior System proper has six planets in it.  Aprior Primus and Secundus are very close to Aprior and are used for mining and manufacturing; Tertius is in the habitable zone and houses the majority of the subsector's population; and Quartus, Quintius, and Sextus are gas giants, with moons used for manufacturing, military research and training, among other things (like the headquarters of Internal Security, on Aprior Sextus Echo).

Aprior Tertius is similar to Old [[Earth]], although it is larger, with surface gravity almost twice that of Terra.  Because it was the first world in the sector to be colonized, Aprior Tertius is the sector capital, and the primary base of the Knights.  It is usually called Regius to set it apart from the other worlds.  Regius is largely urbanized and industrialized, although the Regians have instituted environmental and social policies to prevent the pollution and decay normally associated with industrialized, highly populated worlds.

One major feature of Regius is the Torch, the Fortress-monastery of the Knights Inductor, buried within a ridge of extinct volcanoes.

====Nyx====

Nyx is a white dwarf from an eons-old supernova; its sole remaining world, Thanatos, is a dead, cold lump of rock notable for containing a metal with potent anti-Warp properties, which the Apriori forge into weapons.  A [[Necron]] tomb was discovered in the process of mining; it seems that its presence is related to that of the metal, though it is unclear which came first. ''Subject to change, pending new Necron [[Codex]].''

====Romulus and Remus====

Romulus and Remus are a binary star with two planets: one gas giant orbiting both (Roma Dista), and one hot rocky world orbiting Romulus (Roma Proxima).

====Tarquin====

Tarquin is a star similar to Aprior, with a "double planet" orbiting it: two Agri Worlds (Tarquin Ventrus in front, and Tarquin Dorsus in the rear) in each others' Lagrange points.  The remnants of Hive Fleet Draco orbit Tarquin Ventrus.

===Marion Subsector===

The Marion Subsector faces the center of the galaxy, so it faces the Imperium and the Tau Empire.  As such, it receives the most Imperial and Tau traffic.

====Marion System====

In mid-M39, this system was settled by a Commandery of the [[Sisters of Battle | Order of the Sacred Rose]].  The [[Eldar]] attempted to dislodge them, as Chatur-Marion (the fourth world) was a Maiden World, though the actual Commandery is on Dvi-Marion, the second world.  When the Sisters learned what the [[Knights Inductor]] had in mind for the Sector, and especially their [[heresy|unusual]] (to say the least) policies, they decided to stage a coup, or failing that, to burn the whole Sector to cinders.  They were stopped when the Knights' fleet destroyed their orbital assets and reformed them into the Order of Reason's Light; since then, they have used their expertise in hunting and destroying heretic cults to grow their influence, expand their numbers, and become the dominant institution in their system and Sub-Sector and a major player in Sector politics.

====Norion====

A border system that tends to suffer heavy losses from outside attackers, especially in the [[Tau Empire]]'s Third Sphere Expansion.  Its history, combined with proximity to the [[Imperium]] and distance from major population and government centers in the central Sector means that it is the most pro-Imperial system in the Sector.

Norion V is the most populous world in the Norion System.  After an economic depression, resentment over the various non-human populations (inflamed by Puritan Preachers sent by the [[Ecclesiarchy]]) boiled over, resulting in anti-Sector protests, riots against Radical Preachers and their allies, and an attempt to withdraw from the Sector Charter.  The Norion System was Inquisitor Lord Damnos's first target for his Crusade.

===Subsector Lida===

In M28, Lida was settled by some [[Eldar]] who sought to avoid the impending [[Slaanesh|Fall]].  When the Aprior Sector was being settled by humans, the Apriori did not have sufficient firepower to dislodge the Eldar from Lida and withstand the inevitable counter-attack, so they left Lida with a whole subsector to itself.  The threat of an [[Emperor's Children]] Strike Cruiser convinced the Apriori to reach out to Lida and assist in repelling the invasion; they parted amicably.
