If you don't get what I mean, they released 3 books about Chaotic: One being the Ultimate Guide, and the others in a series called the M'arillian Chronicles. To my knowledge, they both explain several thing about M'arillian and Mipedian(?) past, like how Mugic worked differently, how the Mind Control worked, etc. That's all in Khilaian Sphere, the first one. To my knowledge, there's a second one about the Owayki Warriors, though that one's more of a children's book.
My question is: What specific things did they talk about? What questions were solved, or left unanswered? Anything of important note?
If there's spoilers, please put them in spoilers but I think the info would be super helpful. I don't have access to the books and can find little to nothing on any of them.
