Necromancers and the DeathDay Massacre
Witches and necromancers hate each other; that’s a commonly known fact. Nightwitches hate necromancers with just as much passion as any other witch: what sets nightwitches apart is that they tend to express their hatred in subtle ways.
Witches were some of the most heavily persecuted people in the chaotic days after DeathDay. To escape the necromancers who persecuted those who practiced the witch’s craft, the witches fled to the secret places that the Nightwitches had prepared for them. But the Nightwitches themselves had disappeared even further, not gathering together in the circles as was the wont of other witches. Instead, they practiced their craft in solitary, or in pairs of teacher and student, and so their craft survived.
