Id like to learn about how the age of sigmar came to be I guess is what I am getting at.
Ooo, that is a lot of reading, potentially
The End Times books are a good read (might recommend you dive into the novels rather than the gaming books, if you are not going to be playing
WHFB and just want to know what happened - they will be cheaper too).
The downside is that this may get you wanting to know what happened before
that, and this would be the rabbit's hole

There area lot of Warhammer Fantasy novels set in the World That Was, and a lot of them are very good.
Would suggest you start with the End Times novels, and then see if you want to know more. The Gotrek and Felix books might be a good place to begin that journey...
