After some discussion with @CaptainBritton, I'm thinking of a slightly more technologically advanced and more fuedal version of the aftermath of Alexander's conquest, something like 300 BCE but as I said with more medieval advancements. If anybody has anything to add in, feel free to reply/go to the chat.
