Dorak was a Jedi Master of the Human species (a male), and a part of the Dantooine Jedi Enclave Council. Throughout both the Mandalorian Wars and the Jedi Civil War, he held the position of Chronicler of the Jedi. Furthermore, he was among the many Jedi Masters that provided training to Revan during the time the future Dark Lord spent as a Padawan.
Sometime between 3964 BBY and 3956 BBY, Dorak became a member of the Dantooine Council, taking the place of Bala Nisi. As the Chronicler, he possessed extensive knowledge concerning the history of the Order. To ensure the continuation of his work, he chose Deesra Luur Jada, a Twi'lek, as his successor, imparting all of his wisdom to him. In addition, Dorak oversaw the distribution of the first lightsaber crystal to apprentices, guiding them in selecting their roles within the Order. He would present them with hypothetical scenarios, analyzing their responses to identify their inherent tendencies. While he offered recommendations, the final decision rested with the apprentice.
During Revan's re-education at the Jedi Enclave situated on Dantooine, Master Dorak took on the responsibility of acquainting Revan with the Order's core principles, imparting essential historical knowledge and discipline. Master Zhar Lestin subsequently assumed responsibility for the remainder of Revan's instruction.
Master Dorak managed to survive Darth Malak's Sith bombardment and witnessed the war's conclusion. However, he, along with Vandar Tokare and Zhar Lestin (two other former Dantooine Council members), met his demise at the hands of Darth Nihilus during the Conclave on Katarr in 3952 BBY.
