Even the real "Creator" is constrained by the world itself.
Thus, the Celestial Chariot that leads all things into the realm of light and navigates the long river of dreams is also bound to be restricted.

And the future outlined by the Fourth Chronicle doesn't fixate on "fate" itself. It doesn't enforce how such a "future" ought to occur… it simply predetermines that this "fragment" of the future will inevitably exist.

"…So initially, what Philip had to do was to bring the Book of the Celestial Chariot back into the world."
