I always imagined this world as being medieval. But why would they stay that way after thousands of years? I had this idea that the world is very static and that’s one of its core problems. While it’s a paradise, it’s a very stilted world that’s dying to its lack of innovation and reformation. Advanced technology could even be hoarded away by the kings and aristrocrats who want to remain in power.
Perhaps magic is so potent that most things can be done with it. Nobody needed to create machines. Perhaps the normal people have grown corrupt and lazy too, because there is always summer and crops grow around the year. This could cause all sorts of problems. And lack of a seasonal cycle would affect the cultures. Has there never been any natural disasters, really? Could there be a couple ones that happened and they were a big deal, because they never happen? How would people even interpret such events?
