We’re dealing with an “alternative history” campaign here. Just. The history of this world has been largely similar our own up until recently. Exactly when the two histories have split isn’t too clear.
In the campaign world, discoveries and inventions are happening that will slowly (very slowly) drive the world towards a steampunk society.
The world is not guaranteed to be totally free of Cthulhuesque wierdness
The year is 1841. The players are working for Q Company of the British Army.
Technology is largely the same as found in our own history at the same time, with one or two exceptions.
History is mostly the same as home, except the Independence movement in America has been put down.
