Jedi Enclave
From the Encyclopedia of Speculative Fiction - http://encyclopedia.wizards.pro
The Jedi Enclave was a secret Jedi training centre located on Dantooine prior to the Jedi Civil War.
The Enclave was established by Jedi Master Vodo-Siosk Baas, 40 years prior to the Mandalorian Wars. Exar Kun was among the students trained there, whose fall Revan would later repeat.
The complex was fully equipped as a Jedi refuge, housing a Council Chamber, sparring rooms, dormitories, common rooms and a Jedi Archive only open to the Masters of the Order. At the time of the Mandalorian and Jedi Civil wars, Master Dorak was Chronicler of the Academy. The building also served as a focal point for the local community, housing a landing pad and several shops. Common folk could be found milling around just outside the Enclave walls, where they were safe from Mandalorian raiders and native kath hounds.
The Jedi of the Enclave also worked as a local security force, solving kidnappings, murders and family disputes. They did, however, refrain from becoming involved with the aforementioned raiders, until Revan returned to the academy to retrain in the Jedi ways.
Shortly after Revan's return, the Enclave and the surrounding area was bombarded by the Sith fleet and attacked by their soldiers. The Enclave was left a wreck, and the concentration of dead Jedi left an 'echo' in the Force.
Five years after the Jedi Civil War, the Jedi Exile encouraged the scattered Jedi to gather at the rebuilt academy, but its new life would be cut short as Kreia murdered the Masters.
