Hexenwerk is the Eisen way of sorcery. It is illegal in many parts of the country, but elsewhere, it's a valued tradition helping with fighting the monsters and undead roaming the country. A lot of practitioners are perfectly nice people, but their craft uses some very unusual and unsavoury ingredients which is responsible for the bad reputation Hexenwerk has. And of course, there are those who have crossed over into villainy.
