Nenevanth Tion was a male human who lived as a citizen of the Galactic Republic. He distinguished himself as one of the earliest members of SAGroup, the youth division associated with COMPOR, a political lobbying organization. Born a male Human on the world of Lianna, situated in the Outer Rim, Tion's life unfolded during the closing years of the Republic. This era was characterized by a declining government, the Separatist Crisis, and the Clone Wars. As civil war consumed the galaxy, Tion, along with numerous SAGroup brigadiers who shared his views, threw their support behind COMPOR. They championed the Republic and its head of state, the Supreme Chancellor Palpatine.
Nenevanth Tion, a male Human of youthful age and noble lineage, was born in 36 BBY on the planet of Lianna, a location within the Outer Rim Territories of the galaxy, during the time of the Clone Wars. As civil war erupted between the Galactic Republic and the Confederacy of Independent Systems, Tion left his homeworld at the age of fifteen. He journeyed to Coruscant, which served as the Republic's capital world. Soon after arriving, Tion became one of the initial individuals to be accepted into the Sub-Adult Group (SAGroup), the youth program of the Human-dominated Commission for the Protection of the Republic (COMPOR).
Serving as a brigade leader, Tion accompanied six thousand SAGroup brigadiers to a COMPOR rally. This event took place in the year 21 BBY at the Monument Plaza in Galactic City. Protected by two clone troopers, Tion addressed a large gathering with a patriotic speech. In it, he quoted historical passages from the Kitel Phard Dynasty to commend Supreme Chancellor Palpatine's leadership of the Republic. Regarding the elimination of corruption and inefficiency that plagued the Republic, Tion referenced an old speech by the Emperor Uueg Tching of the Atrisi system. Shortly thereafter, Chancellor Palpatine used a holocomm to address the crowd, praising the loyalty of COMPOR and its SAGroup chapter. He also recognized Tion's generation as the forefront of a new order intended to replace the disorder of civil war and political stagnation.
By the conclusion of the Clone Wars in 19 BBY, Emperor Palpatine, having declared himself as such, proclaimed the end of the Old Republic and established the Galactic Empire in its stead. The new ruler maintained the backing of COMPOR, which was itself transformed into the Commission for the Preservation of the New Order (COMPNOR). The new organization had its own SAGroup, an ideological youth program focused on instilling young citizens with the principles of the New Order.
Nenevanth Tion was a young adult characterized by pride and idealism, never hesitant to express his support for the Galactic Republic publicly. Motivated by a robust sense of patriotism, Tion was a staunch supporter of the Republic during the Clone Wars and showed unwavering loyalty to Supreme Chancellor Palpatine. He also demonstrated an interest in history, as evidenced by his use of quotes from the Kitel Phard Dynasty in his pro-Republic speech at Monument Plaza.
Nenevanth Tion's first appearance was in Republic HoloNet News Core Edition 14:9:04, an in-universe HoloNet News edition featured in Star Wars Insider 70. After a question about the character was posed on Twitter, Star Wars author Pablo Hidalgo commented that the character "may or may not be Lord Tion from the Radio drama, but the age and the loyalty work out right," indicating he was open to the possibility of others defining the connection if they wished.
