In a factory full of magic, some magic is bound to slip out and cause havoc.
Magical industry knowledge is precious and hard to find. Even the most minor spells require enormous nondisclosure waivers. Most of the experts claim the knowledge under patents to ensure they could make the most money possible. The harder that knowledge is to discover, the less competition you have. Magic factories are known to be high risk because of the stigma of sharing information. Unfortunately for the workers at this factory, that includes information on how to be safe.
