I’m not going to comment on the lore bits themselves on your document just yet, simply because it’s been a long, long day and my eyes are really really tired. I will read through soon, though!
A bit of advice on google docs and big documents that I CAN provide, however, is that Headers and the Outline are your best friend - especially on projects like this. This is a link to an RP campaign outline I made for my guild years and years ago, and you can see how helpful headers and an outline (on the left side) can be.
If you plan on continuing this project, and it gets larger, adding these will let you jump down to different sections without scrolling for ages.
Also, kudos on taking on this project; I’m a fan of the idea, and even tackled it myself a while back with my A Proposed Revision 🖊 rewrite of the WoW Lore.
Going to bookmark your post and see where things go.
This is me these days; I try very hard to ignore Shadowlands entirely, and act like we’re just chilling on Azeroth rn. When people bring Sylvanas’ and the Shadowlands, my characters go “people are still hunting for her”, and “Shadowlands? I’ll believe it when I see it; it’s all just rumors and hyperbole.” Both of these things have suited me just fine.
