Order of the Origin

The Choirs of the First are as follows:

UPPER CHOIR

• SALVATORES: the highest choir; the elite vanguard of the Order and the foremost "swords" of the Universe; largely active on the battlefield (see: EUB) and in command of parties (Sidus or Sidera, or Constellation[s]) of varying size depending on their merits; often under the direct wing of a Firstborn (ex. Salvatore of the Second, etc.). The leader of the Salvatores is known as the Sidereal Salvatore.

• SENTINELS: the second highest choir; the elite rearguard of the Order and foremost "shields" of the Universe; as equally on the battlefield as they are posted as stationary wards (static Sentinels, as a whole, are called the Steadfast) near Sourcegates/weakened boundaries; often under the direct wing of a Salvatore. Sentinels also maintain the Nexus. The leader of the Sentinels is known as the Sidereal Sentinal.

• SUSTAINERS: the third highest choir; the foremost healers of the Order and dedicated menders of the Sourcering; if they are not combat medics for the Upper Choir, Sustainers are reinforcing Sourcegates/weakened boundaries (see: Azoth); many Sustainers are also posted at the Order itself or throughout the Universe as regular doctors of ranging specialties. The leader of the Sustainers is known as the Sidereal Sustainer. Collectively, the Sidereal leaders are called the Syzygy.

LOWER CHOIR

• SECTATORS: the lowermost choir; populated by initiates, scholars, and (most of all) by commonfolk devotees not looking to advance in rank; the majority of Sectators are drawn to the Order for the mystery of its founders and the knowledge contained within its halls; scholarly Sectators can study and graduate from the Order like a university (as the credence of the Firstborns is to guide and to teach, a significant amont of scholarly Sectators go on to become teachers themselves).
  
  There is no "leader of the Sectators," but professors are addressed as Shepherds, the overall academic faculty is the Symposium, and the devout refer to their collective as the Society. Shepherds can be learned in studies outside the Sanctuary; many of them were once Nigredo and Albedo, for example. These learned Shepherds, particularly those of a concurrent Rubedo status, are often trained to preside over the Courts of Serenity.

NOTABLY, Starlyngs are generally not aware of other universes (the Omnicosm), nor are they aware of inbound abominations, that the Order defends against them, and other related goings-on. Even within the Order, the duties pertaining to the Upper Choir (outside of Sustainers that become regular doctors) are classified information. To the general public, the Upper Choir is seen as the "Order version" of the Preservation instead, and thus there is an open and longstanding relationship between both Covenants. (Although, internally, they often butt heads.)

The Order also associates with superiors of the All is One convenant for the procurement of Upper Choir needs (weapons, armor, etc.; see Threads and Needles, Thimbles, Azoth), as well as the special media (paper, ink, etc.) used by Archivists to fill the Sanctum and Emphemeris libraries and by (chiefly academic) Sectators. Covertly, the Upper Choir of the Order works with Spectra from the Way of the Darkscythe to dispose of EUB, purifying the remains of Distorted Starlyngs, and other matters pertaining to unlife.
