In the Blind Eternities, the only thing you can be sure of is that nothing is set in stone. Of course, given the impermanence of rocks in the infinite multiverse, the parable loses its gravitas, but you get the point. Across endless parallel universes, there will be infinite variations of the same thing. But eventually, perpetual chaos begets order.

Suppose you draw infinite curves on a sheet of paper. Some will overlap, and some will be parallel. And some will have such minor differences that differentiating between them would be pedantic. Now, if the paper was a space with infinite dimensions, those curves would represent different worlds and their timelines, practically but not accurately. This analogy is quite limited and does not fully represent the Blind Eternities. But it represents how different worlds can have similarities.

If you take a clumped cluster of worldlines and average them out, you get a timeline of how things go. A canonical timeline, if you will. It can also be represented as stories.

As an example of such stories, here is a brief meta-overview of one:
It begins with a species of space worms trying to survive the heat death of the universe by consuming resources. These worms consume anything and everything, including each other. A parasitic species, unable to comprehend the Blind Eternities, like a frog in a well.

But today's story is not of that. Today's story begins with a Demon Lord.

In the Blind Eternities, the only thing you can be sure of is that nothing is set in stone. Of course, given the impermanence of rocks in the infinite multiverse, it loses it's gravitas, but it gets the point across. In the endless parallel universes, there will be infinite variations of the same thing. But even perpetual chaos has order. And most variants of the same world have commonalities. A canon, if you will. For example, a space whale that grants powers based on a person's trauma might visit an ordinary world with ordinary people. A completely ordinary world with no supernature. A variation of that world could begin the same way. An ordinary world, where supernatural exists only in stories. But a demon lord of extraordinary power visits this one, whose apperance heralds the coming of the supernatural. And unknowing, sets off the wings of the butterly, bringing the storm of his end.
