1. Canonically, the Book of Shadows was inherited by Seira, Zaion's psuedo-daughter, and passed on to the first of Seira's three pseudo-children, Raki, and then onto her biological daughter, Yoshie. Since Yoshie and her daughter died the book remained at their estate for a long time. However, Zaion's descendants do have connections with dark gods, and it's possible that Atsaan could have established connections with the book itself.

2. I like this idea.

3. I'm also in support of this.
