There , he joined the Baran Do , a Force - based organization on his homeworld , and became a leading member of the Sages . He was a Baran Do Master by 19 BBY , when the Clone Wars came to a sudden end with Order 66 and the Great Jedi Purge , which nearly eliminated the Jedi . With the new Empire in control of the galaxy , Hazz feared that the Baran Do might suffer the same fate as the Jedi Order , and he decided to create a secret sect of the Baran Do dedicated to preserving the order ' s knowledge ; if the Baran Do ever were eradicated , the sect would be able to reinstate the order . Hazz traveled deep beneath the surface of Dorin , where he discovered and expanded a system of caverns . The new sect , which was named the Hidden Ones , was established down in the caverns , and Hazz became their first leader , taking the title of the Hidden One . Hazz decided that in order to protect the Hidden Ones ' secrecy , no one could ever be allowed to leave the caverns . As such , new members would have to accept that they were dead to the outside galaxy . The Baran Do tradition of the dying ceremony — a ceremony in which a Sage pretended to die , and then secretly traveled down to the Caverns of the Hidden One to join the sect — was established as a way for the Sages to join Hazz ' s new sect . Hazz also decided to come up with a telepathic technique for communicating with the Baran Do on the surface , as a way for reinstating the Sages if they were ever destroyed . By 43 ABY , Hazz was no longer the leader of the Hidden Ones . Legacy .

However , Koro Ziil , the Master of the Baran Do who had previously trained Solo , was no longer present with the Sages at their temple . The Skywalkers eventually discovered the Hidden Ones , following senior combat instructor Charsae Saal to the caverns , where they met with Ziil , who had recently become the sect ' s leader . Ziil would hold true to Hazz ' s rule of letting no one leave the caverns , but Luke eventually confronted Ziil and defeated him . Afterward , the Hidden Ones were disbanded , and the sect ' s members returned to the surface . Personality and traits . Tokra Hazz was concerned first and foremost with the progression of the powers and philosophy of the Baran Do , and was thus more interested in the safe - keeping of knowledge than the well - being of individual lives .
