Like, even if some major events of your world do have relevancy, i believe making an entire timeline is a bit too far, considering that you have to add all of that thousands of years of countless events to your plotline at some point, and perhaps connect it to other details of your own worldbuilding, i'm pretty sure you need to have expanded quite a lot in your worldbuilding to do such thing, what are your thoughts on this?

Even if some major events of your world do have relevancy, I believe making an entire timeline is a bit too far, considering that you have to add all of those thousands of years of countless events to your plotline at some point, and perhaps connect it to other details of your own worldbuilding. I'm pretty sure you need to have expanded quite a lot in your worldbuilding to be able to do such a thing.

Is there a reason to go to all that effort?
