Marrine Kreische is the Margrave now in charge of the Factory Alliance after her father, the archduke, was killed along with the archduke of the Fantasia Union on her wedding day. While she is still in love with Alexis, the political tensions between the Alliance and the Union has made it impossible to talk with Alexis in a peaceful setting.
