From the back cover:
Welcome to the 19th Century
...that never was!
It is a world of wonder, of horror, of adventure, of magic, of strange technology and unprecedented cultural revolution. This is an age that should have been, filled with radium-powered flying machines, clockwork automata, and steam-driven computers. It is an age of dark magic, sinister secrets, and unholy cults. It is a time in which the world teeters on the edge of chaos, where the enlightened scientific mind battled against ancient superstition and ignorance, in which the souls of all mankind hung in the balance.
The Widening Gyre presents a glimpse at the Industrial Age as it truly was, envisioned by those far-sighted luminaries and Savants who looked beyond the feeble limitations of man and created a world in which science, technology, and logic triumphed over the mundane physical limitations of the Universe. And yet, Logic’s victory is far from complete. This is also a dark and gothic world, where monsters from ages long past still prowl and men with evil motives call upon ancient sorceries to grant them the power to control the world. The Widening Gyre is a world in which you’ll play consulting detectives and adventuring academics, occultist thrill-seekers and Savants both heroic and insane, all working for a secretive organization of benevolent technologists who seek to prevent the dark monsters of humanity’s past from overwhelming its bright and burgeoning future.
Welcome to The Widening Gyre!
