The first printing press, courtesy of Johan Gutenburg, appeared in 1450.
This invention is right up there with penicillin, the Internet, the machine gun and all sorts of other, radical world-changing technologies and discoveries. The printed word allowed ideas to percolate up and down the social strata of societies in a way we might struggle to understand, or take for granted, right now.
In fact, the written word was a vehicle of the Reformation, and later Fascism and Communism. Like the Internet, it was a force for both positive and the negative. It accelerated education. It was instrumental in the emancipation of the oppressed.
In short: it was a Big Deal.
Now in Project Eternity we have a world where, for some reason, technology has developed unevenly. Imagine how much more dangerous that world might be --- where guns and mighty galleons, a world where Gods can inspire the development of bombs, coexist with dark aged superstition and dogma?
So this thread is about that. Start with a counter-factual if you wish, or perhaps how this fits in with the lore of the world.
And I know that printing presses aren't as sexy as swords, spells and loot but in the context of the setting I think it's an interesting topic.
