I have tried making my own worldbook. Can you pretend to be my curious friend?

Looking for someone to grill me with questions about my worldbook and make me doubt everything I've built so far

I have tried on making a worldbook for my own book (doesn't matter). Could you do me a favor and pretend to be a friend who asks me a ton of questions about it? The goal is to knock me out of my comfort zone and make me second-guess everything I've come up with.

To make it easier for you, here's a quick rundown of my world:

It's based on real-world history, but with a twist. Humans were the last species to evolve into thinking beings. To make things worse, they're largely cut off from Astrum (the magic dimension).

The central event of the Great World War (I haven't landed on a proper name yet) between humans and other species was the coming of the Messiah. He "divided" himself among his 17 disciples/apostles. Five of them decided to enhance humanity by creating the "Blessed Ones" (essentially a kind of vampire).

Even though humans are cut off from magic, they can still disrupt the entire magic dimension simply by dying. All magical energy accumulates in the soul, which, after death, travels to Astrum and disturbs the nameless/shapeless beings that exist there. To stop this, those unnamed entities created the "Charons" — enhanced souls capable of freely traveling between dimensions, ferrying souls from point A to point B (the afterworlds).

Sorry in advance for any English mistakes.
