One thing I'd be interested to see is stats on more governmental or paramilitary groups that might interact with/oppose the paranormal. There are stats on SI, which covers the police and could be extraploated for a federal X-Files division, but I wonder what an anti-wizard or anti-magic military unit might be statted out as (motto: "We don't believe in fairies!") Or a department whose job is to cover up the occult community because the government doesn't want a panic. Or a group of diplomats whose job is to negotiate treaties with the various magical folks in the country so that humans can keep on living normally. Or a generic terrorist or militia group that aligned with magical forces to achieve their evil ends, and so has some spellcasters among the soldiers.
(Loving the RPG, by the way; I'm GMing a game and it's a lot of fun. I'm excited about the new Paranet book too!)
