If you're still confused, I think the best example of this is Destiny. At one point the universe gets kind of confused, and kind of splits into two. And so does Destiny, because he is destiny, and destiny itself has split. He can't just re-merge Destiny - he doesn't have any power over Destiny, any more than you would say "Zorba has power over Zorba". If someone tears off my leg I can't hold it on by the power of my will (although that would be pretty damn cool) and Destiny can't keep himself from splitting either.
Which leaves the Endless all surprisingly vulnerable, in the end, but that's not just a different entry, that's one I'm not even planning to write.
Back to the subject.
Terry Pratchett wrote a series called Discworld. And a much more minor plot point in Discworld (well, compared to the Endless) is Story. Story, in Discworld, is an actual force. Million-to-one odds are pretty much dead certainties (but only if it's exactly a million to one, and someone points this out, and someone else says "but it just might work".) If a king has three sons, and the older two go to confront some monster, and are killed by it, the youngest son is absolutely assured of defeating the monster. And will probably find a princess who needs rescuing along the way.
I'm sure you can see where I'm going with this, but just in case you need it spelled out:
Someone should write a story about Story.
