Arth Campaign Seting

From publisher blurb:

The year is 1904, but the world is not our own. Sure, the continents are all there and the people are there, as are many recognizable places and events in history, but things are changed: The Holy Roman Empire still reigns; the Chinese claimed California; the Mongolian Empire stretches across much of Asia. And things have gotten weird: Dark creatures stalk the night; there are rumors of alien influences at work; mystics wield mysterious powers; strange new sciences are seen every day; the dead rise from the grave. All the while colonialism is at its height and the remaining blank places on the map are being revealed. The world is ripe for adventure.
