Dorak was a dark-skinned, Human Jedi Master at the Jedi enclave on Dantooine during the height of the war against Darth Malak. Dorak was known for his skills with a lightsaber and his knowledge in their construction. Additionally, for newly knighted Jedi, Dorak chose the initial crystal the Jedi would use in building their first lightsaber. He tried to pick a crystal whose unique properties matched the unique personality of each Jedi.
Dorak was also part of the Jedi council that made the decision to take a risk on a captured Darth Revan. During the war between the Jedi and the two Sith Lords, Darth Malak and Darth Revan, the Jedi managed to confront the two and capture Darth Revan. Malak remained at large and the Jedi hoped the knowledge locked within Revan's mind would allow the Jedi to locate Malak and hopefully defeat him. With powers only the collective strength of powerful Jedi Masters such as Dorak, the Jedi essentially gave Revan a clean slate, wiping his mind of all knowledge of his Jedi and Sith dealings. Dorak and the Jedi hoped that, while the knowledge would not be available to him consciously, the Jedi might be able to gleam from his subconscious vital information that would lead them to Malak.
When Revan's quest brought him back to Dantooine, Dorak, along with Jedi Masters Vrook Lamar, Vandar Tokare, and Zhar Lestin debated the issue of whether or not Revan should be allowed to initiate his Jedi training once more with the possibility of becoming a Jedi Knight. Dorak and the Masters feared that since Revan had fallen once with dire consequences, history might repeat itself. However, Dorak and the Jedi, through their discussions with Revan, felt that Revan was indeed a different person and deserved a second chance. When Malak attacked the Jedi enclave from space, the academy was destroyed and many were killed. It is unknown if Dorak was one of those who escaped the destriction.
