Dimitri Rattim was a high-ranking interrogator and state policeman of the Srav Federation during the Cruentusian War. Prior to the formation of the Srav Federation, he had served in the resistance movement on Sviat, interrogating collaborators with the Infinite Empire for information. Known for his bluntness and short temper, Rattim nonetheless commanded respect from high-ranking Srav figures such as Ivran Gresev and Volita Taika, both of whom petitioned for him to be promoted to a kommissar.
