From the Back Cover: There's more to the world than most of us know. Academic wizards and gutter mages, vampires and werewolves, Men in Black working for a secret religious order and a police division investigating Fortean crimes. The cities and the very landscape encompass haunted places and lost bubbles of history, faerie courts and places of power. But you know. There's truth within the legends and folklore. You stand at the edge of the Hidden World. Maybe you've seen it and can't ignore it. Maybe you're from the Hidden World, but with ties to humanity. Join us on a journey into the Hidden World with Liminal, a self-contained role-playing game of fantasy in the modern day United Kingdom.
