Before Chicago was a city, before the white man cleared the prairie and swamp to build their roads and towers, there was the pool. The pool had always been. A doorway to another place, a place filled with dark things seeking to enter our world. The Keepers of The Fire kept watch over the pool, keeping the Weendigo, the man-eaters at bay.
Now, the guardians of the pool are the unwanted of society. The ones no one will miss if snatched in the night to be Weendigo meat. Under the city they clash, the man-eaters and the forgotten Keepers.
