Stephanie chose her name, Valkyrie Cain, for a couple of reasons. Stephanie felt very powerless when compared to Tanith Low 或者 China Sorrows, perhaps even Skulduggery, as well as all of the bad buys which kept trying to kill her. She didn't like being weak and wanted to be strong, so she chose a figure of female strength for her first name, a "Valkyrie." Her last name is a little 更多 intimate in origin and stems from a 评论 that Skulduggery made about how she has a "penchant for raising cain," basically meaning that she causes trouble.
