Seese was a Herglic of the female gender who existed during the time of the Republic Dark Age. She made her home in the city known as Calimondretta, which was located on the planet named Syned. Syned was the capital of the Arkadianate Sith state, and she arrived there in the year 1038 BBY.
Seese relocated to the Arkadianate planet of Syned in 1038 BBY, establishing herself in the city of Calimondretta and becoming a citizen of the Arkadianate. Due to the policy of Sith Lord Arkadia Calimondra, which involved rotating citizens through different jobs throughout their lives, this Herglic mother had held at least five different positions by the year 1032 BBY. These jobs included teaching, processing algae, metallic reclamation, serving as a tactical officer within the Citizen Guard—Arkadia's security force—on Arkadia's flagship, the New Crucible, and finally, working as a tour guide in Calimondretta. It is also known that she had four children who also resided within the Arkadianate.
In 1032 BBY, Jedi Knight Kerra Holt journeyed to Syned, and Arkadia instructed Seese to guide Holt around Calimondretta. During this guided tour, Kerra observed that Seese possessed a friendly and likeable disposition. Through Seese's explanations, Kerra gained a deeper understanding of life within the Arkadianate and Arkadia's governmental policies. Seese, in turn, found herself able to appreciate Kerra, despite the latter's status as a Jedi Knight and her own loyalty to the Arkadianate. Like many citizens of the Arkadianate, Seese had been influenced to believe that Arkadia was a kind and caring leader. Seese also internalized the state propaganda, believing that Arkadia would eventually govern the entire galaxy. During the Siege of Calimondretta, Kerra would later reflect on her fortune in not encountering Seese during the conflict, as it would have been difficult to harm someone she had befriended just hours earlier.
