Sullivan

Sullivan was a crew member who worked with Anh Edonia on Sera. Ever a pragmatist, he initially resisted Jim Kestrel's attempts to recruit them into sinking a Koan Dreadnaught. But as Anh and Jim grew closer, Sullivan fell in line--or so it seemed.
In an effort to save his own hide, he kidnapped Jim Kestrel's cabin girl Klarisia and brought her aboard the dreadnaught as a hostage. In the end, he chose his sides poorly, as Anh, Jim, and Jin Bei boarded the dreadnaught and rescued Klarisia, killing Sullivan in the process.
