Devastated by the Sith centuries ago and once shrouded in the nebular mists of the Cron Drift, the planet Ossus had largely faded from the galaxy's memory. Once a flourishing center of Jedi culture and learning, Ossus revealed only hazardous wastelands and abandoned ruins to those few brave enough to venture its treacherous path. Yet, despite its scarred past, Ossus has experienced a remarkable rebirth.

​

Historically, Ossus was the proud home of the Great Jedi Library, constructed over a thousand years ago. This vast repository housed countless records, ancient texts, and holocrons that chronicled forgotten civilizations and pivotal events in galactic history. For generations, its hallowed halls nurtured the wisdom of the Jedi and served as a beacon of enlightenment for the Republic. However, the destructive forces of the Sith brought calamity upon the planet, shattering its legacy and consigning it to the realm of myth.

​

In recent decades, as the Jedi Order struggled through prolonged wars with the Sith and Zakuul, Master Gnost-Dural foresaw the Order's potential extinction. In a desperate bid to preserve sacred teachings, he secretly established a hidden colony on Ossus. Chosen for its remoteness and natural concealment, the colony flourished beyond expectations. Innovative environmental reclamation techniques transformed the barren surface into fertile land with effective water purification systems, ensuring that life could endure even in such desolation.

​

A critical decision soon followed—whether to remain connected to the broader galaxy or to isolate entirely. After intense deliberation, Master Gnost-Dural insisted that the colony remain completely cut off, its location safeguarded by advanced sensory arrays and signal jammers. This isolation was intended to protect its precious legacy from the prying eyes and potential threats of the outside world.

​

Yet even as Ossus bore the scars of the Cron Supernova—a seared wasteland of rock and sand—its survival was nothing short of miraculous. Recent findings preserved in a mysterious datacron reveal that the very force of that supernova, when combined with the residual life force of a former Jedi stronghold and the unique astrophysical properties of the Adega system, played a role in sparing Ossus from total obliteration. These revelations sparked hope and inspired efforts to reclaim the ancient legacy.

​

Today, the Great Jedi Library of Ossus has been re-established as a thriving center of learning and preservation. Restored to its former glory, the library now serves as a vital repository for lost lore, advanced research, and the timeless teachings of the Jedi Order. Modern scholars and Jedi alike, from across the galaxy, now study within its restored halls, ensuring that the hard-won knowledge of the past continues to enlighten future generations.
