Civil action
Due to knock-on effects of the The Necromancer Crisis people in Gallica began having very negative opinions on magic practitioners of any kind, not only those that practised dark or forbidden magics.
While originally organizations like the Raven Knights were searching mainly for necromancers, their hunt quickly expanded to encompass Witches, Demonic cults and other kinds of dark magic, all sanctioned by the powers-that-be.
However over the following years their efforts did not end there. They both encouraged a general distrust of all magic users and often fanned that into open hatred with their persecution of "dark sorcerers". They were the reason why this time is also called the "Age of Book-burnings"
For many decades it was simply the rule that all magic users were suspect of being demon worshipers, witches and necromancers.
It was a wide-spread social movement, supported by the peasanty, the nobility and the church. Any that spoke out often found themselves as the target of hateful mobs of frightened peasants whipped into a frenzy by agitators.
Thus the art of sorcery largely went into hiding. Even still, many events that had nothing to do with magic and were simply natural tragedies such as diesease outbreaks or harvest failures were blamed on dark sorcery. Many innocents were also blamed and executed simply because they were used as scapegoats by their neighbors that didn't like them very much.
The general hatred towards magic user was strong across several generations until the Gallican royalty put a stop to it.
The Witch hunts mainly affected Gallica but were also felt in Pucraele, Ravil and other minor nations that existed at the time.
They also had the notable effect of making the deity Argus Panoptes retreat largely to the spirit world, seeing as humanity was not very open to knowledge and research anymore.
