Lieutenant Solian was the Barrayaran Security Liaison Officer assigned to the Komarran merchant vessel, the Idris. He was a Komarran, one of the first generation who'd been allowed to become officers in the Barrayaran service. He'd had good reviews from past assignments and was generally well-liked by the Komarran crew of the Idris, but did not appear to have gotten especially close to any of his coworkers or charges. He disappeared from the Idris during the fleet's stopover at Graf Station in Quaddiespace; the subsequent events are told in the story Diplomatic Immunity.
