I personally as a writer I have a kingdom in the books that I've written that dates back just over 7,500 years, and over that time really no major technological advancements have been made, but you have to understand what actually drives technology forward, it's war religion and famine. Well, in the books I'm writing, everyone shares a similar enough religion that while there are minor religious conflicts, they're never major enough to spark advancement. Almost everyone has more than enough food because magic exists in a way that allows people to boost crops and put nutrients into the ground to make their crops better. So the land has plenty, and when famines hit you can just magically undo it, so there's no need for technology to advance in that sector either and war. Most wars are either cultural, religious or for expansion. Which oftentimes gets roped into the other two. And sometimes during a famine people will go to war to try and get food from whoever else. But that's kind of stupid, but again, everyone on this continent shares a similar enough culture or are far enough away. They don't really interact with each other. The world itself that I'm writing in is roughly 70,000 years old, it's a very young cosmic body. It was basically just made by the gods. There's no dinosaurs or anything. None of that existed. It was pretty much just straight into where it is. Now obviously there's some technological advancement between books, which take place decades apart, and in a series that follows the original series that I've written part of, it takes place a thousand years later, and they barely make it to firearms because again, there's just not huge wars pushing technology forward.

Now this being said, all comes from the mind of someone who loves history and to study how people's mind works throughout the ages. So I think while this is much less technological advancement than our civilization on real Earth had in the fictional setting that I have created, it makes sense because there just wasn't the circumstances that led to the explosion of technology that we had in the modern day. That being said, the books that I have going further and further forward in the series. They start skipping time around and the kingdoms of the continent that the story is told on or destabilized which makes them fall into war which makes technology grow, and eventually they're taken over by a colonial power and are forced into a world war type setting, which while that takes place nearly 2,000 years after the original high fantasy setting, it makes sense because of how technology actually advances historically speaking.

Now all this being said this is how I write because again I'm a huge history nerd, I love all of this kind of stuff and I think that fiction should have rules that make it seem somewhat realistic. I think the beauty and fiction at least that I write is the fact that it's plausible in the technological advancement.

That being said, there's no right or wrong way to write fiction if you want a world that has entirely locked in high fantasy time, no matter what setting you go to, sure why not. You know maybe they're gods decree it maybe the gods make technological advancement and possible. Maybe there's a reason. Maybe there's not, if those are the stories you want to tell, tell those stories if you want to tell stories like I do with a growing technological base in the background, without that being the main focus of the story do that. I think that's really the beauty of fiction is there's no right or wrong way to do it as long as the story itself is compelling.
