This campaign is intended as a Fringe/X-Files style of investigative campaign. The PCs are aware that things beyond the norm exist and are working as part of a government task force for investigating and stopping threats to the American way of life.
The main environment for the campaign is the city of Chicago, Illinois. However, considering that the threats may not even be from this world, the campaign will not be confined there.
