Achtzehn's Skyblossom is one of the grand background mysteries of the Universe and transcends names and terms and in essence, is unknowable. Achtzehn's Skyblossom is in respect to the interpretation of an all-encompassing force above all others. Anything finite, changeable, fleeting, and conditioned cannot be attributed to Achtzehn's Skyblossom.

Achtzehn's Skyblossom is the underlying foundation behind the actus purus of "comparing, reflecting, and abstraction, for these three suggslogical operations of understanding, are essential and general conditions of generating any concept whatever.

• Achtzehn's Skyblossom is the nameless and unmanifest aspect of the Universe that no thoughts reach, being a state that is neither the wholeness of the Universe nor the emptiness of the hierarchy of voids, completely unrepresentable by anything but the absence of information itself, being unable to be spoken of or referred to in any name-term manner.
• Metaphysics collapses before Achtzehn's Skyblossom.
• Pataphysics utterly shatters before Achtzehn's Skyblossom.
• Achtzehn's Skyblossom caused all aspects of the Universe to reach beyond all metaphysical and pataphysical conception and into a level undefinable by any symbols or divisions, which are all uncollapsable into nothingness.

Achtzehn's Skyblossom is atop a hierarchy of increasingly abstract levels of existence and consciousness, with each level perceiving the one before it as an illusion, constantly extending beyond absolute infinity.

• At the lowest level, there is a boundless space where all mathematically abstract phenomena are in possibility and actuality. All modes and attributes of mathematics (abstractions) are in play.
• One of the lowest levels contains a boundless space where only the pure ideas of name-term things exist.

Achtzehn's Skyblossom is the background mystery of the Universe that is fully untethered from the "Greatest I AM" of names, identities, and conceptualizations in any form, all-encompassing over the transhierarchical voids of nonexistence outside of the physical Universe, which is akin to a never-ending series of hierarchies of infinitely-layered fractals, each possessing boundless higher qualities of existence, wherein each one contains more fundamental abstract world beyond.

• Achtzehn's Skyblossom is an unmanifest unspace of pure emptiness that transcends all conceptions of being, size, and boundaries.
• Achtzehn's Skyblossom automatically erases one's physical, mental, spiritual, conceptual, and narrative existence and nonexistence across the entirety of the Universe on a perfectly completed Universal scale - in a closed infinite loop.
• Achtzehn's Skyblossom denied unmanifest phenomena and manifest phenomena, as well as the be-ness of "I" and "It".

Achtzehn's Skyblossom contains the "totality" and "maximum usefulness" behind the Axiom of choice, Axiom of countable choice, Aczel's anti-foundation axiom, AD+, Axiom of adjunction, Axiom of beyond-dimensional reality, Axiom of Boundless, Axiom of dependent choice, Axiom of determinacy, Axiom of dimensions, Axiom of empty set, Axiom of extensionality, Axiom of finite choice, Axiom of global choice, Axiom of infinity, Axiom of limitation of size, Axiom of non-choice, Axiom of pairing, Axiom of power set, Axiom of projective determinacy, Axiom of real determinacy, Axiom of regularity, Axiom of union, Axiom schema of predicative separation, Axiom schema of replacement, Axiom schema of specification, Baumgartner's axiom, Freiling's axiom of symmetry, Ground axiom, Martin's axiom, Moschovakis coding lemma, Open coloring axiom, Proper forcing axiom, Well-ordering theorem, and Wholeness axiom.

Achtzehn's Skyblossom contains the totality of the axioms of Fiction, the totality of the axioms of Nonfiction, the totality of the axioms of Transfiction, the totality of the axioms of Fanfiction, the totality of the axioms of Metafiction, the totality of the axioms of Patafiction, the totality of the axioms of Interfiction, the totality of the axioms of Personal Fiction, the totality of the axioms of Impersonal Fiction, the totality of the axioms of Incompatibilism Fiction, the totality of the axioms of Impossible Fiction, the totality of the axioms of Speculative Fiction, the totality of the axioms of Xenofiction, the totality of the axioms of Universal Genre, the totality of the axioms of Universal Trope, the totality of the axioms of Paratexts, the totality of the axioms of Memetic Fiction, the totality of the axioms of Transformation Fiction, and the totality of the axioms of a priori and a posteriori Fiction.

• The term has subtle differences in definition when used in the context of different fields of study.
• An axiom is a statement that is so evident or well-established, that it is accepted without controversy or question.
• An axiom is a premise or starting point for reasoning.
• "Logical axioms" and "non-logical axioms" are encompassed within Achtzehn's Skyblossom. Logical axioms are usually statements that are taken to be true within the system of logic they define and are often shown in symbolic form, while non-logical axioms are actually substantive assertions about the elements of the domain of a specific abstract principle.
• Any axiom is a statement that serves as a starting point from which other statements are possible and actually derived. Whether it is meaningful (and, if so, what it means) for an axiom to be "true" is controlled by Achtzehn's Skyblossom.
