The Core Worlds were home to Osadia, a planet. To safeguard the mysterious school situated there from any disruptions, its precise coordinates were concealed and erased from all star-charts.
A forested and secluded planet, Osadia housed the New Generation Academy, overseen by Antos Wyrick. This enigmatic institution, which sheltered young children like Jarael and Chantique during their formative years, engaged in commerce with the Crucible, a slaving syndicate. Eventually, their dealings soured, prompting the Crucible to dispatch Fleet Captain Dace Golliard to orchestrate a large-scale assault on the academy, aiming to abduct students for their slave trade.
As of 3963 BBY, the Crucible continued to utilize the planet as a strategic hub.
Despite The Essential Atlas's Appendix indicating the Osadia system's location within the Core Worlds, the map illustrating the Mandalorian Wars positioned the planet in proximity to Vinsoth, a world found in the Outer Rim Territories's.
