So I'm newish to the game. Can someone explain me the recent lore? | tcgmode

I have been playing for like five months and I know a little bit of what happened around the brother's war and also a little bit about Nicole Bolas early moments, Zendikar, Eldrazis and so on. But when it comes to the lore referring to Strixhaven or Reality fracture with Jace etc I'm quite lost....
