Black Magic Nights
Twisted spirits from some distant dimension, the Shedim want only to cause pain and suffering. Unable to manifest, and weak even on the Astral Plane, they seek out bodies – living or dead – to possess and animate.
With all the above-ground cemeteries, New Orleans was in a bad place when they started to make their way to our world – right about the time Haley’s Comet swung by in 2061. Not knowing what they were, most people blamed the only other zombie-makers around: practitioners of Voodoo. That kicked off a significant crack-down by local and federal law enforcement, and made old prejudices flare right back up.
Worst of all, the animosity toward Houngans just distracts people from the very real and ongoing threat posed by the Shedim.
