From Forbidden Kingdoms Master Codex Introduction:
By and large the world of Forbidden Kingdoms is very much like our own. The timeline for the setting spans the 50 years from 1889 to 1939 and captures the full reign of the pulp era. We’ve set the stage on an alternate Earth that is full of “what if” possibilities. One of the main concerns that we had when developing this project was the enormous expanse of technological development during the time that we had presented. Instead of limiting ourselves to something linear I asked the rest of the development team to extrapolate on existing information that we had gathered, thereby turning it into a speculative exercise. For example, one of the most popular logistical strands is the development of Babbage’s analytical engine. What if (I really love saying that) he had acquired the funds to craft his machine and it had actually worked? The computer age would have developed sooner, wouldn’t you agree? Computations on a mass scale could be accomplished much more quickly, and who knows where that might’ve led early on.
Forbidden Kingdoms is a world that still has the spark of adventure in it, where you can still traverse the darkest parts of Africa in search of hidden caches of treasure or stop the World Crime League from taking over the world. It is a place where Good vs. Evil is as simple as black and white, and where “the seed of crime” does indeed bear bitter fruit.
