And if you don't have players that enjoy all that background, and it's just you wanting a detailed campaign background, it's less stress to get it all done. Just do with it what you like, as you go along.
I'm kinda there at the moment myself. We've been using the Forgotten Realms as our default setting for nearly two decades. I started running a series of adventures in October, and somewhere along the way, one player made a comment about how the supposed ruler of Aglarond could not be who I was saying it was... However, the game rolled on and no one paid much heed or had their fun diminished.
When I eventually pointed out we were playing 150 years earlier than we usually do, it was cool with everyone. But I hadn't started out with the idea that we were playing in the 'past'. But it fit, worked for me, worked for them, and we're keeping on with it... No big whoop.
They like having a story, and having things tie together, but tight continuity is not job one....
