Soussho was a Mirialan male and a member of the Data Seekers, a secretive organization that sought to unravel the mysteries of the Anoat sector's shrouded history during the reign of the Galactic Empire. Caught behind the Iron Blockade enacted by Imperial Governor Adelhard in the wake of the second Death Star's destruction, Soussho took to operating on worlds such as Bespin and Burnin Konn, where he traded secrets like currency, offering work and lesser information to those he deemed likely to advance the Seekers' cause. Soussho was in charge of the Seeker's transfer pilots.
