- "When Republic Special Forces accomplish an especially hazardous mission with seemingly impossible odds, it’s often Colonel Rian Darok who is credited with their success. With a commanding presence and blustery persona, Darok asks his Special Forces troops for nothing less than their unwavering obedience, which they gladly offer time and again. High-risk offenses requiring on-the-fly conception and execution were commonplace in warzones like Corellia and Ilum, where Colonel Darok particularly thrived. His brand of decisive thinking under pressure has earned him the respect and admiration of many, including Special Forces General Elin Garza and Republic Supreme Commander Jace Malcom."
- ―In-game Codex (Persons of Note)
Rian Darok was a Human male trooper who served in the Galactic Republic military up until the end of the Cold War. During the outbreak of the Great Galactic War, he secretly defected to the Order of Revan while pretending to still serve in the Republic. Working alongside Darth Arkous, who had also defected, Darok coordinated the attacks on the planets Korriban and Tython at the same time, ensuring that Revanite agent could extract important artifacts from the Jedi Temple and Sith Academy.
He and Arkous then departed for Manaan to present their findings and have them absolved into new soldiers being created for the Order. Both he and Arkous were present when an individual who had been manipulated into assisting the assaults caught up to them and attempted to stop them, but the two departed in a subnautical vehicle before activating the station's self-destruct sequence.
The two retreated to the planet Rakata Prime and commanded the final stages of the Star Forge, being recreated with the artifacts recovered from Tython and Korriban. Both were killed when the same individual from Manaan infiltrated and stormed the construction site.
