I’m doing some fantasy worldbuilding for the heck of it (and also a possible future D&D campaign), and I’m very keen on moving my world out of ‘medieval stasis’ – not just technologically, but culturally/politically. Do you have any general suggestions on how the society/politics of a fantasy world can be post-medieval, yet still distinctly premodern? In particular, are there any specific developments you like which could have been, but never came to pass in RL history? Thanks.
