Classic Lore catchup?

As the title implies, anyone able to give a lore catchup for Dragonflight? I played the first month or so and then put it down to focus on IRL stuff, and have been debating on coming back since I've been having fun with playing around on Classic Era and would like to get the most out of my subscription, but coming back I have no idea what's happening with anything at all... via /r/wow https://ift.tt/VmnOKYT
