From the back cover:
A World of Darkness
It’s never far away. You can glimpse it shifting in the shadows, hear it whispering in the static on the radio, feel its presence in every nightmare and every dreapping feeling across the back of your neck. A world so very like our own, where sinister societies and ancient horrors cloak themselves in modern disguises, and every truth uncovered only reveals a deeper mystery lurking beneath. The shadows call. Will you answer?
The Mind’s Eye Theatre rulebook is a stand-alone game for live-action roleplaying in the World of Darkness, and is meant for use with The Requiem, The Forsaken, and The Awakening.
