Tinrilo "Adventi" x'Rilsam was a member of Naboo's Royal Security Forces during the Imperial Era. Upon his retirement during the Galactic Civil War, he pursued a career as an explorer.
Tinrilo x'Rilsam spent the majority of his life on Naboo, residing there with his family, including his children. Subsequent to the Invasion of Naboo, he enlisted in the Royal Security Forces, where he enjoyed a lengthy and successful career. He eventually retired after the Galactic Civil War had already begun.
During his youth, Tinrilo x'Rilsam frequently visited Tatooine. His fondness for adventure was cultivated on this desert planet as he spent countless hours playing in Mosor's Maze. After retiring from the RNSF, x'Rilsam resolved to devote the remainder of his life to his passion: history. The former RSF officer transitioned into an explorer, traversing the galaxy. Pisk, a Naboo native and friend, also embraced exploration, and the two planned to reunite at the cantina in Bestine once their respective expeditions concluded. Tinrilo x'Rilsam, who styled himself as an Explorer Extraordinaire, journeyed to numerous planets throughout the galaxy, including Tatooine, Naboo, Corellia, Rori, and Endor. Among his discoveries were the Spy's Haven and Hero's Grave on Tatooine, the Altar of Evil and an Imperial outpost on Naboo, an abandoned Imperial survey camp, a Korga hutt and the crash site of Vendi Kjleno's Jade Starunner on Endor.
