The Paranormal Police Department (PPD) is in charge of making sure supernaturals keep in line and play nice with normals. There are divisions in every major city on earth, and there is even one that exists in the Netherworld. All PPD officers are genetically enhanced. This makes them more capable in their particular class than standard supers. A PPD mage is typically more powerful than a standard mage, a PPD vampire has more speed and agility, and a PPD pixie uses foul language just a wee bit better than her standard counterpart.
There are currently two series being written in the Paranormal Police Department, but more are on the way.
