Beign 1200 instead of 2023 is one of the easiest rabbit holes to never be able to leave.

Once you see the copy pasta of history, you say, that is a copy-pasta of history
and then you can never unsee it.

It wasn't that kingdom came and went, but they all flourished about the same time.
And then all the lore starts making sense.

But, i must state that this area is all highly speculative, because trying to untangle this huge lie is really daunting task. So, you only get bits and pieces.
