A Contest of Nisse and Release
Pronounced: SAI-dee-re-al (sɑɪˈdirɪəl) or SI-dee-re-al (səˈdirɪəl)
Also known as the Viziers, the Sidereal Exalted are the champions of the Five Maidens and the keepers of Fate. The Chosen of the Maidens are the savants and astrologers of the Exalted, as well as matchless martial artists. During the Primordial War, they acted as advisers and spies for the Solar and Lunar generals.
Near the end of the Age of Dreams, they undertook the Great Prophecy, which eventually led to the murder and usurpation of the Solar Exalted. Because of certain actions taken during the usurpation of the Chosen of the Sun, all 100 of the Fivescore Fellowship became stricken with Arcane Fate, which makes it very difficult for people to remember they exist at all. Because of this, the Sidereals have lurked in the shadows since then, manipulating the course of not only the Realm, but Creation as a whole. They are most gifted in Martial Arts, however, learning Sidereal Martial Arts with the most ease out of anyone else in Creation.
After the Great War, the Fivescore Fellowship was put in charge of the upkeep of the Loom of Fate, fixing snags in the Tapestry of Creation, and advising and Lawgivers and the Stewards. They were also, befitting their position as Celestial Exalted, each allowed a vote in the Lower House of the Deliberative. However, as time went on they saw their Solar rulers becoming more and more corrupt. The Viziers foretold a Great Prophecy, and after much debate acted on path they thought was best.
One portentous Calibration, the Seers put their plan into action. That night, Meru burned. Over the five days, all but a handful of the Solars were purged, their shards locked away in the Jade Prison and sank into the ocean. To protect themselves, they used incredible Astrology effects, actually shattering the Constellation of the Mask. To this day, though everyone knows the truth, no one can prove the Vizier’s involvement in the Usurpation. The attack was not without cost, however, and the Sidereals suffered many casualties as well.
The Shogunate and the Realm
For the next two hundred or so years, the Sidereals rebuilt Creation from behind the scenes. They made sure the proper communities thrived while those that were supposed to fell. They ushered certain Terrestrials into power, making sure the emerging Shogunate would have the infrastructure to survive without the Glorious Golden Gods. For about 750 years, the Shogunate thrived. However, during that time a lot of the glories made by the Solars and Lunars broke down. It was never expected that the Chosen of the Sun and the Moon wouldn’t be around to fix things. Slowly, Creation dwindled from the Age of Dreams to a pale imitation.
Then the Great Contagion struck. Hundreds of millions wiped out practically overnight. The Seers in Yu-Shan did the best they could, but nothing could stop the virulent disease. Hot on its heels came the Balorian Crusade, killing millions more. Luckily, something else happened the Seers didn’t see. A Dragon-Blooded woman activated the last bastion of Creation’s defense, the Realm Defense Grid. Once it was seen that Creation would indeed survive the twin tragedies, the Viziers once again got to work. They nurtured the nascent Realm into the sprawling empire it is today, rewrote then brought the Immaculate Philosophy to the height it is today, and still continued to fix snags and tears in the Tapestry.
