Tigard Manes, identified as male, held the rank of cadet within the Galactic Empire. He was stationed at the officers' academy located on Arkanis. Shortly after Zare Leonis arrived, having infiltrated the academy with the aim of rescuing his sister, he encountered Manes among several others. Leonis was unfamiliar with Manes's designated homeworld. Subsequently, Manes participated in a live-fire training exercise alongside Leonis, Bedal Cerroux, Chan Harra, Xan Lanier, and Anya Razar. Razar characterized Manes as prone to becoming flustered under pressure, often losing sight of the mission's goals. She cautioned Leonis that they would all need to maintain close communication with him and reiterate key points from their initial briefing.
Subsequently, Manes was among a group that witnessed a wandering nerf being devoured by a sea creature native to Arkanis. Brendol Hux, the academy's commandant, then posed a question to the cadets, inquiring about methods to prevent similar occurrences. Manes was the first to volunteer a suggestion, proposing the installation of a gate. Hux acknowledged the "practical" nature of the suggestion, but pointed out the potential delays it would cause for authorized personnel and also expressed his belief that completely shielding against all of the galaxy's hazards was unfeasible.
