The Hidden Ones were a subsect of the Baran Do Sages, a faction of Force-sensitive Kel Dor living on their homeworld of Dorin. In 19 BBY, after the end of the Clone Wars and the rise of the Galactic Empire, the Jedi Order was hunted and purged. One Baran Do Master, Tokra Hazz, feared that his Order would suffer the same fate. In order to ensure that the Baran Do were not driven to extinction if such an attack occurred, Hazz formed the Hidden Ones with the purpose of preserving the knowledge of the Baran Do Order; therefore, if the Order was ever eradicated, it could be reinstated. Hazz became the sect's first leader, known as "hu'aac-du'ul-staranjan"—or simply the Hidden One—and was given absolute rule over the sect.
