I'm actually all for the Book of Shadows (indirectly) causing some major plot events.

Atsaan's "infinite power" he promised to Grodus might have been the Book, which he might've been holding at the time. Grodus being a future renegade archdemon (With god tier-level Space powers, even), he would be a far more proficient carrier of the Book.

The Ao Oni aren't a race observed elsewhere in existence, they have no related species and they have been concentrated in a very small area. Perhaps the original "X" was transmuted by a past carrier of the Book, who followed its instructions without question and was originally planning on creating something completely different. The creature became subject to the Book's will, eventually dying and being revived by Revelian later on, which is when it attempted to carry out the original purpose the Book had intended.

On the subject of Zalgo's appearance, Waldo warping through timespace without switching out with his counterpart Lazro shouldn't have been possible, and only an outside force such as the Book could have caused this event to happen.
