Duseuso was the lead historian for the Journal of the Whills on Ashlan Four in the years following the Galactic Civil War. Originally a novice historian, Duseuso began his research by looking into the time stream in an attempt to chronicle the life of Annikin Skywalker for the Journal of the Whills. Ussej Padric Bac, the Shaman of the Whills, told him that there was a different interpretation that could be provided from the time stream. Ussej then recounted his own experiences with Annikin Skywalker throughout Skywalker’s life.
In the years that followed, Duseuso became the lead historian for the journal. He spent decades researching individuals who participated in the Clone Wars who had escaped mainstream galactic attention. He compiled his documentation for the Journal of the Whills in the hopes of shedding life on lesser known individuals who helped shape the future of the galaxy.
