Is there an even further state of nonexistence that could devour the nothingness? When something becomes nothing, what happens to that something? Is the nothing itself something? If the nothing truly is nothing, then wouldn't that make even the smallest amount of something be, by definition, everything, and the nothing, itself, not exist? If the nothing is not truly nothing, as in it is something that can be defined as nothing, as opposed to a nothing that cancels out its own existence by being, itself, nothing, would that mean that something can turn the nothing into something that truly is nothing?

Say I have an empty box, one foot cubed of internal volume with the sides impermeable to all things that might want to enter the box. Inside the box is nothing, devoid of anything, making the box filled with nothing. However, this nothing is still a measurable thing, there is one cubic foot of nothing in the box, which defines it as something, though a something referred to as nothing, as this something contains no things. This nothing can also be destroyed in about the same way something can be destroyed; if something were to occupy the space where there is nothing, the nothing in that space would cease to exist, being replaced with something, and if all of the nothing came to contain something, there would no longer be any nothing in the box.

If the nothing truly is nothing, in that it is a non-measurable utter nonexistence, then this box, no matter how large or hollow it is, would be completely solid, as the internal sides would be directly adjacent to one another, as internal sides require an 'inside', which must always be something, even if there isn't anything in there. Placing something into the box wouldn't make the box contain something, as there is no space for the something in the box, even though the box has nothing inside. This might also mean that this box with nothing inside would contain something: the sides of the box welded together by virtue of there being nothing between them. In this instance, 'nothing' would be meaningless, as no matter how much nothing there is between two somethings, they will never have any space between them, and any one something would fill all of the nothing around it by virtue of the nature of nothing's non-existence.

In either of these cases, something is powerful and has the ability to displace, destroy, or ignore nothing, though nothing can do the same to something in the first.

Nothing isn't something you can really find in its true form within any world, except for when a world is truly ending.

Think of it more like a book. This book is the entire world. Everything that happens in the world is written down in the book. If you're a character in the book, on this level of reality, you exist only as a concept maintained by the sum of the words, basically. On the ground level, you have a physical body and actually really exist, yeah, sure, but on this upper level, you're the result of words on the page.

This metaphor doesn't work so well when we also say that the book is alive, and is the author of every story, but is also reading every story, and the characters also dictate their own stories, but, look, go with it for a moment ok.

So you aren't even on this same level as the book, right now. You're a thing created by the book. And now here comes a fire, and the book catches on fire, and EVERYTHING burns to ashes. The only thing that was ever reading the book was itself. Now the book is gone. The words are gone. The concepts are gone and there's no one at all who remembers them. What is left is ashes on the floor.

Now replace the fire with Nothing, instead.

The ashes on the floor is the voidwaste.

The book was a world.

"Nothing" isn't a passive force, either. It is an active, draining force, and the words of the book are always running off the pages and being consumed by the nothing around it. As the world begins to forget its own story, the nothing creeps in, and pages start to burn up, and ink is soaked off. The only way you can push back the nothing is to have more stories, grow more pages, more words, and outpace the hunger of tranquility. Eventually the world will fail, it will stop being able to produce new stories, and it will hemorrhage its contents into the void.

The voidwaste is not truly nothing, of course, but its ground is the remains of worlds--each world has only the slightest bit of Anything left, and that memory of itself manages to manifest mostly just as a flat expanse of ash and dust. Just overhead in the sky is where the real nothing is, churning and bowing low and threatening to even consume the voidwaste itself.

Tabrix wears a cloak that's a world itself that constantly produces Story to keep herself safe in the void, because even SHE, despite being 1/2 nothing interpreted, is still at danger, and all of herself could be consumed.

Nothing used in a world as an interpretation is usually not actually 0. It's usually more .000000000000001, which is close enough to be Nothing as far as things are concerned internally. Kaha Voidwaste (the other half of Tabrix's metafcitional body) is is actually full 0, which is Rare and Terrifying and Very Powerful, and that she has an Identity at all is because she's a hole defined by the shape of Tabrix's story built around her. Tabrix is constantly feeding Story to her other half to keep from being devoured by herself, basically. The larger her story grows, the larger the hole grows, too, mirroring the shape that the story takes.

Which is why when Tabrix comes to a world, if she stays there too long in one spot, eventually the rest of her will catch up...

Is there anything a world can do to augment their defense against the void? Insulate itself with a few stories it can't possibly be forgotten? Craft an infinitely looping story, or one that branches off into an infinitely recursive series of self contained spin-offs as regenerative armor? Do the stories need to make sense, or just exist? What is the nature of a story?

Everything eventually ends, and new things come to be from their remains. This is the circle of life.
