Hi and welcome. I think one youtuber who is as in love with the lore as Moose is would be Ethys Asher. He doesn't post many videos these days because of Youtube's calculations but he does use twitter n twitch a lot more. He also will go back if new stuff has made past comments not 100% true any more. I'd also tell you to go and read the side stories SE puts out. They might not have a lot of lore but there's a lot of connective tissue to things that tie into the story that explain some whys to some character developments that you won't see on screen. A lot of people might give SE a lot of flack for things but one of them is so far not forgetting things they've brought up in the past. Even something that might seem small and forgetable they'll bring it up again and you'll go wow.
