One of my biggest pet peeves in made up fantasy worlds is the fact that their worlds are absolutely static for hundreds or thousands of years at a time. Nations rise and fall constantly! Maps shift! First the kingship is in Eridu, now it's in Bad-Tibira! Then Bad-Tibira fell and the kingship was taken to Larag!

(Of course, this makes the trope I'm complaining about Older Than Dirt, since the Sumerian King List claims their kings ruled for tens of thousands of years)
