Kjarval was a member of the crew of the Nostalgia for Infinity, and a friend of Sudjic. She possessed no outward signs of mechanical modifications; however, her body appeared biologically optimised for an aquatic environment.
During a training session in preparation for the capture of Dan Sylveste on Resurgam, her battle suit was co-opted by Sun Stealer and used to attack Ana Khouri. To protect her gunnery officer, Ilia Volyova shot Kjarval repeatedly, killing her.
