Humanity lives in the sunlit world of what we believe to be reality. Unknown to most there is, unseen by most, another world, possibly many other worlds running side by side with our own. These places are just as real, but not as brightly lit. These places are the sources of myths, legends, and nightmares. The Marquette Institute and Department of Preternatural Activities (DPA) are the latest in a long and illustrious line of such organizations established to help safeguard the human race from the monsters living in the spaces between reality and nightmares. From Miskatonic University to the European Order of the White Shield, The Marquette Institute and the DPA are heirs to a powerful and complex legacy. These stories just scratch the surface of the operations and investigations conducted in almost 200 years of operation.
