Rian Darok

In 3637 BBY, he was in command of the Korriban Incursion. Simultaneously, the Sith Empire launched an Assault on Tython, compelling Darok to organize a defense of the planet. The Republic strike team under his leadership during these consecutive engagements was awarded the Medal of Valor, and Darok was subsequently assigned to assist the Jedi in their recovery efforts following the assault. Following the Assault on Tython, Darok maintained a relatively discreet presence, engaging in strategy sessions with special forces officers and dedicating considerable time to his terminal. However, he submitted two intelligence requests to the Republic Strategic Information Service: one concerning "Isotope-5 Proliferation and Deployment in the Empire" and another regarding "Known Smugglers: Inner Rim."

Theron Shan, an SIS agent, grew suspicious of the timing of the attacks and Darok's information withholding. With the assistance of Lana Beniko, who harbored similar suspicions, Theron tracked Darok to a clandestine laboratory complex on Manaan. Lana, formerly an advisor to Darth Arkous of the Dark Council, knew Arkous had orchestrated the Tython assault. They discovered that Darok and Arkous were members of the secretive Order of Revan, initially believed to be a marginal group within the Empire, who aimed to harness Rakata technology to create an "Infinite Army." The Republic and Imperial forces pursued the two men to Lehon (also known as Rakata Prime), the former capital of the Infinite Empire, where the Revanites were overseeing the creation of their army. Confronted at the summit of the Temple of the Ancients, Darok refused capture and was killed alongside Arkous, despite Theron's desire to capture him alive for further information about the Revanites. Shortly after, it was revealed that they were not the true leaders, as Revan himself arrived.
