Jedi Order

The Jedi Order was an ancient peacekeeping organization unified by its belief and observance of the Force, specifically the Light Side. The Jedi were considered guardians of peace and justice in Vale and Vacuo before the Great War and were perhaps known for teaching individuals to use their Force powers. They were also known to be the sworn enemies of the Sith Order, an organization of Sith that relies on the Dark Side of the Force, and led the Sith Empire. The Jedi Order ceased to exist immediately after the Great War concluded and chose to adopt a secret society after the founding of the Huntsman Academies.

The Jedi, in modern times, are considered to be what inspired the Huntsmen, similar warriors of peace that fight against the Creatures of Grimm. In truth, many Huntsmen were Jedi in disguise.

Leadership
The Jedi leadership consists of the Jedi High Council, a collective body of twelve Jedi Councilors that govern the Order's members. While a Grand Master is recognized as the head of the Jedi Order itself, the Master of the Council serves as the elected leader of the High Council. However, both of these titles are usually given to the same individual at a time.

Historically as the leaders of the Jedi Order, the High Council often associated itself with a Kingdom's leadership, as evident with both the Kingdoms of Vale and Vacuo.

Jedi Ranks
The youngest members of the Order, these children were given the rank upon their entry into the Jedi Order. Either born into the Order or recruited at a young age, Initiates, with consent, were removed from their families and trained at a Jedi Temple. After a considerable amount of training, Initiates are selected for tutelage and apprenticed to either a Jedi Knight or Master. These Initiates are granted the rank of Jedi Padawan. In accordance with Jedi tradition, Padawans are required to wear a long braid of hair behind their ear.

However after the Great Jedi Purge and the subsequent retreat into a secrecy society, this tradition was formally dropped by surviving Jedi to avoid being discovered by the Imperial Kingdom, whom held both anti-Sith and anti-Jedi policies. Following a period of nearly a decade of training under a master, disciplined Padawans become eligible to attempt the Trials of Knighthood. If successful, a Padawan begins their life as a Knight and is no longer attached to a master. Knights are free to do as they wish, accept missions from the Council, pursue specialized training as either a Seeker, Guardian, Consular or a Sentinel.

Historically, a Padawan's braid was also severed by the High Council. After the Great Jedi Purge, Padawans weren't subject to wear a braid for the duration as a Padawan. Jedi Masters are Knights who have shown a complete and great understanding of the Force and its mystical energies, and managed to train a Padawan on becoming a Jedi Knight are elevated to the rank of Master by the High Council. However, in times of war, the title was often granted to Knights who showed promise in the ways of the Force.

Certain Masters, typically wise and experienced, were appointed to either one of the Councils of the Order based on their experience. However, only the most powerful and wise Masters served on the High Council. Historically, Master of the Temple was a title given only to Jedi Masters who were placed in charge of a Jedi Temple. At the time, the Jedi only held a single Temple in Vale, Vacuo and Mistral. Due to this, only three Masters were given the title.

In the modern age, Huntsman Academy Headmasters are given the title by the High Council, such as Ozpin who serves as Beacon Academy's Headmaster.

A notable holder of this title was a Jedi Master named Salem, who fell to the Dark Side and became the First Sith, having also established the Sith Order and its Empire. Jedi Councilors are Jedi who currently serve on a Jedi Council. This can be either the High Council, or the Councils of First Knowledge, Reassignment and Reconciliation.
