I also ran out of space but other cool guy is a channel called Stories from the Imperium! He writes lore accurate stories just about anything 40k! He also takes requests! His writing is also just beautiful

Warhammer is awesome! And it’s really cool that you’re getting involved! For lore videos I’d suggest giving Adeptus Ridiculous and NUMBSKULLS a try, they’re both people who explain lore in really cool ways to other people, Adeptus Ridiculous also has another channel that explains Fantasy lore too
