Sector 12

Sector 12 is a one of twelve sectors in the space colony known as Heaven's Fence. This sector contains nine planets in total including Paris: Earth (it's capital planet) and Dil-Ariuth IX. Before the Mage War, the governing mage of this sector was Litan Boss.

Brief History
Sector 12 is the bottom-right, or lower-East area of the Fence. During the "War of the Western Third," Boss was the first mage assassinated by Wilhelm Ryan who, upon the end of the War, declared himself "Supreme Tri-Mage" of all the Fence.

After the Black Rainbow ended, the Tra-Nuvis Monks on Dil-Ariuth IX found Mariah Antillarea by their riverbank. Three or four years later, when a plague broke out there, the young lady healed the monks afflicted earning her the Messiah title and establishing the monastery as her base of operations when she was 21. Later, the Prise visited Antillarea there to discuss her rebellion against Ryan, and a spy overheard the conversation. Though he was captured, it was too late, and United Red Army forces decimated the Monastery and all who were on its grounds. Antillarea, being in contact with Inferno Kilgannon, was able to flee Dil-Ariuth IX and headed to Paris: Earth where they were to foil Ryan's plans to administer the Monstar Virus. They were too late, and due to the Monstar Virus corrupting Coheed Kilgannon who thus became The Monstar, Sector 12 was separated from the Fence; it's nearest star, Star VI, was snuffed out disrupting the power to the Keywork in that area. Prise on Paris: Earth sacrificed themselves to stabilize the energy remaining in the Fence. It was only after Cambria Kilgannon killed herself and offered her own psychic energy to reignite Star VI that the Sector was stabilized into the pull of the newly-freed star's gravity.

It was after this event that the separated Sector became known as the Silent Earths, with each planet numerically identified based on how close they were to the free-star.

Notable Planets
As mentioned, this sector has a designated capital planet with eight follower planets, for a total of nine. We do not know all of these planets, but the following are the ones of note.

Paris: Earth
The first planet (capital) in Sector 12. This planet is notable for being one of the Fence's most technologically advanced planets with dense cities highlighted with skyscrapers. Still the planet has remote areas of complete nature. It was there that Ryan took the Vessels of the Monstar and White Ruineer the former of whom snuffed out the life of Star VI which caused the separation of the entire Sector from the Fence. The latter than reignited the Star to save the planets (and people) from endlessly drifting about through space. Paris: Earth is the third planet from Star VI in this new system so it is called Silent Earth: 3.

Dil-Ariuth IX
A desert planet in Sector 12. Known for the Tra-Nuvis Monastery. Little is known about the planet itself, but its desert atmosphere is difficult for the Prise to endure without special apparatus.

Tra-Nuvis Monastery
The monastery Mariah Antillarea was found and raised by. Remote, carved into the side of a mountain, a plague managed to break out in the monastery when Antillarea was just four or five. Though the monks had decided to remove her lest she also contract the disease, she managed to escape their grasp, run to the main monk who raised her, and embraced him with no regard for the issue at hand. This monk was literally on his death bed, but Antillarea's contact completely healed him. This and her subsequent healing of all the afflicted earned her the Messiah title and established the monastery as her base of operations when she was 21 and decided to faceoff against Ryan.

The monastery and its charges were completely destroyed a few years later when Ryan's United Red Army ambushed the rebellion in an overwhelming show of force.

Trivia

 * Litan Boss probably did not become an Onstantine Priest as he was assassinated very early into Ryan's takeover.
 * It is clear from pictures and such that this Sector became our solar system.
 * Paris: Earth is very clearly our own Earth.
 * Along those lines, given Dil-Ariuth IX's desert nature, it may be Venus which would be interesting as Antillarea, a woman Messiah, was born there.
