The Queen of Shadows is the main antagonist of Darkness of the Northern Sky. She is a powerful sorceress/clairvoyant with a dark past and looking to exact revenge on those from her past and replace them in positions of power.
Not too much will be found here, unfortunately, because too much would be given away and the upcoming short called Queen of Shadows and the story, Darkness of the Northern Sky would lose some of its punch. Oh, they’re called spoilers.
