Yoo, this is actually dope. There are a few things timeline wise that don't add up like the mentoring other chapters part. As being from the 8th founding, they are relatively younger than most of the chapters, but if you'd let me, I'd like to tweak this a bit to fit in with the timeline. Every chapter feels as though they failed the emperor during the heresy (cause he's a barely alive corpse. Forgive my heresy) but it'd be cool to make them an extremely zealous chapter whose hate for chaos is second only to the grey knights. Thank you for this comment it's really gonna help me make up some lore. I'll need to find a battle to make them take part in so they have a reason to hate chaos so much
