Barok was a member of the human species and held the rank of lieutenant within the First Order, specifically assigned to the Kijimi garrison.
Prior to the events of 35 ABY, Barok enlisted in the First Order. He was then positioned as a lieutenant within the Kijimi garrison, operating in Kijimi City on the Planet Kijimi, reporting to Captain Athewn Ozi. During 35 ABY, when the First Order was actively pursuing Resistance operative Rey on Kijimi, Ozi instructed Barok to initiate a complete city-wide lockdown. Barok executed this order, utilizing sensor information relayed from a Resurgent-class Star Destroyer positioned above the planet to effectively manage his forces. Following the successful lockdown, he informed First Order Supreme Leader Kylo Ren of the operation's completion.
