- "I offer this record of our civilization to those who will follow. Despite our wisdom and technological achievement, we face extinction. Dogma blinded us to the path of balance and gradually we allowed our pride to corrupt us. The greater control we sought, the further we fell into ruin. I lead the remnants of my people into the great unknown, hoping that we finally find peace."
- ―A Zeffo Sage recording
The Zeffo, also known as the Zeffonians, were an ancient sentient species native to the planet Zeffo. Many Zeffo could wield the Force, which they referred to as the "Life Wind," and those who did became known as sages.
Originated as a peaceful civilization, over time they became more and more corrupt, eventually falling to the dark side of the Force. Facing extinction, the remnants of the Zeffo fled into the great unknown, hoping to finally find peace.
Rise of the Zeffo
The Zeffo had evolved on the planet of the same name, where they had constructed many statues and relics dedicated to several Zeffo Sages, and were protected by the ancient automatons known as Tomb Guardians.
Three of the more esteemed sages, Eilram, Kujet, and Miktrull, were buried in elaborate tombs, both on Zeffo and Dathomir. Their culture extended beyond their homeworld, with elaborate temples and tombs built on Bogano, Ontotho, and Kashyyyk.
The ancient Zeffo had established good relations with the Wookiees of Kashyyyk. Bogano had a great and vast vault built by the Zeffo; as a result, the colony was believed to be a pilgrimage site, due to the presence of the Binog, a large creature of great important to both Zeffo art and culture.
Corruption and demise
- "I recently discovered the Zeffo had some interest in Dathomir. Strange for such a culture to have any fascination with a place so...dark."
- ―Eno Cordova
Though the Zeffo originated as a peaceful culture, over time they became more and more corrupt, eventually falling to the Dark side of the Force. Reigning in the time after Sages Eilram and Miktrull, Kujet ordered the destruction of the astriums the species used in their religious practices while promising his followers power and control over the Life Wind, but he proved to be treacherous and cruel with his reign marking the decline of Zeffo culture.
From his seat of power on Dathomir, Kujet staged a massacre in the halls of the palace, reducing the brave rebels opposed to his rule to ashen ruin. When Kujet died, he was entombed within a sarcophagus that was placed on the walls of his great temple. Within his dead hands, Kujet held one of the last remaining astriums.
Facing extinction, the remnants of the Zeffo fled into the great unknown, hoping to finally find peace.
- "I believe this object allows a Force wielder to perceive the mysteries of the Vault. This is the key and the guide. The Zeffo astrium."

During High Republic Era, the Jedi Padawan Klias Teradine asked questions and was subsequently shown the teachings of Sabracci Sages by Jedi Master Illaga, despite the group not being Jedi. The teachings included the ability to stand on a vertical surface without falling.
In the years before the Great Jedi Purge, Jedi Master Eno Cordova became fascinated by the near-extinct Zeffo. In a record that appeared as a Force vision, the Jedi Padawan Cal Kestis heard the words of an ancient Zeffo, who was leading the remnants of their species into the "great unknown."
