"The Seeds of the Jedi have been Sown throughout the Galaxy, on Ossus, Jedha, Xenxiar, and Others."
―Kli the Elder, Rammahgon[src]

Ossus was a wasteland planet located in the Adega system of the Outer Rim Territories's Auril sector that was affiliated with the Jedi Order and was according to legend, a homeworld of sentient near-human Ysanna species, and also hosted a minority human population. The planet was orbited by at least one forest moon. Certain scholars surmised it was the location of the first Jedi Temple ever built. At the very least, Ossus housed the Great Jedi Library and a temple at some point, from which a mosaic floor was later salvaged and transported to the Order's newer headquarters on Coruscant. The Chronicles of Med'eeth were also salvaged from the remains. It was the homeworld of Veris Hydan.

A lightning storm rages across the barren surface of Ossus

Ossus[5] was a wasteland[2] planet[3] located in the Adega system within the Auril sector[2] of the galaxy's Outer Rim Territories, positioned at the coordinates R-6 on the Standard Galactic Grid,[1] orbited by at least one forest moon. Vicious lightning storms ravaged the surface of the planet. It was a home to kaddyr bugs and kirruks.[2]


Early history[]

Certain scholars surmised it was the location of the first Jedi Temple ever built, although Ahch-To, Coruscant, Jedha, and Tython were also candidates.[3] According to the Jedi,[2] around 12,000 BBY,[6] Ossus became a cultural center of the Order and made a near-mandatory pilgrimage site. Jedi operating along the Perlemian Trade Route are said to have gone to Ossus for unique opportunities to train under other Jedi Masters and contemplate a wider view of the Force.[2] It was one of the planets mentioned in a chapter of the Rammahgon, an ancient Jedi text written by the Jedi Kli the Elder, alongside Jedha and Xenxiar.[7]

According to the Qel-Droma Epics, Ossus was a bulwark against Hutt and Sith agression, and a Jedi retreat and largest repository of Jedi knowledge in history, that was decimated during the Cron Supernova[2] around 4000 BBY,[8] when the Sith Lord Naga Sadow triggered stars in the Cron Cluster to become supernovae. The Jedi managed to save a fraction of the artifacts housed on the planet, which made it to the Jedi Temple on the planet Coruscant via nearby Exis Station.[2]

At some point, the mosaic floor of the temple was salvaged and transported to the Order's newer headquarters on Coruscant.[3]

Galactic Republic[]

As recently as 122 BBY,[9] the Jedi Order suggested they possessed Ossus artifacts that the Qel-Droma Epics mention by name.[2] At some point before the birth of Antron Bach, the last charred fragment of the Chronicles of Med'eeth was also salvaged from the ruins of the planet.[5]

At some point during or after the Clone Wars, Ossus was part of a conspiracy theory, that claimed Count Dooku established a base here to search for lost artifacts. Another rumor swirled around the same time of a secret hyperspace route to Ossus and Jedi possessing hidden fortune there.[2]

New Republic[]

At some point, Jedi Master Luke Skywalker explored the subterranean ruins of Ossus and discovered the original Rammahgon text, which was thought to have been destroyed over five thousand years beforehand.[10]


Ossus was a home to human population and,[4] according to legend, a sentient Ysanna species, a tribal group of near-humans with high percentage of Force-sensitivity among them.[2] Ysanna wore tribal masks and depended on the native kirruk, residing in the nitrogen-rich valleys near the Eocho Mountains. Farming was their main source of food, though hunting with concussion bows became increasingly useful.[2] It was also the homeworld of Veris Hydan, a scholar of Jedi and Sith lore who served as advisor to Emperor Palpatine during the time of the Galactic Empire.[4]

Behind the scenes[]

Ossus was first mentioned in the new Star Wars canon in the 2014 short story The End of History, written by Alexander Freed and published in Star Wars Insider 154.[5] In the Star Wars Legends continuity, Ossus first appeared as a planet that was used by the Jedi Order.[11]
