Editing Supernatural Law:NonPlayerCharacters (section)

===Murder===

A murder of spirit crows that manifest as physical crows and flock in Boston Common, the oldest public park in the United States. Murder has been around since the park was still woodland, and the spirits continue to follow their role of keeping a watch for predators.

The thing is, these days the predators that appear on their radar are mostly human. Wild animals no longer come to the park, and most long term supernatural inhabitants know to keep their distance or at least mind their behavior.

Petty crime does not interest Murder. But they are not called that because they manifest as crows, it is the other way round. Acting like a human or supernatural predator within Boston Common tends to result in the person responsible dying in a freak accident, for the flock of murder spirits possess potent powers of illusion.

The department is usually left with cleaning up the mess. And since eradicating Murder or banning the spirits from the park for good would take an elaborate, park-wide ritual, and the spirits are not a threat to ordinary citizens, the department has settled with putting the park under curfew to keep the predations and the weird deaths to a minimum.
