An Imperial diplomatic mission representing the Core Worlds planet Coruscant was under the leadership of the Apprentice Legislator Chassellon Stevis's mother in 3 BBY. During a pathfinding journey to the Core Worlds planet Alderaan during that year, Stevis revealed his parent's profession to Leia Organa, the Alderaanian Princess, noting that they were both emulating their parents' actions by pursuing political careers for the Imperial.
This diplomatic mission was referenced within Leia, Princess of Alderaan, a young-adult novel from 2017 penned by Claudia Gray.
