One of the Architect Pillars of the Universe, Trumpet of Antithesis, represents the pillar of Theory.

All possible and impossible attributes and modes are in play, Type IV and V Multiverses are categorized by the attributes/modes active in its child universes. Some and All possible and impossible modes of existence are actualized. The uncollapsable hierarchy of increasingly boundless abstract levels of existence and transcendental consciousness, each of which perceives the one before it as fiction is actualized.

Trumpet of Antithesis is free from all notions of Possibility and Nothingness and all unmanifest abstractions and pre-conceptual possibilities and actualities are essentially unreality. True Inspiration that precedes existence that precedes essence such as unspeakable keystone, keystone absolutely immeasurable layers above the name, term, and essence of boundless keystone, etc. are all emptiness to Trumpet of Antithesis. Unfathomable Keystone is a personal illusion. Transhierarchical Divisions like incalculable keystone, measureless keystone, boundless keystone, incomparable keystone, innumerable keystone, unaccountable keystone, unthinkable keystone, immeasurable keystone, unspeakable keystone, uncollapsable keystone, and untold keystone are encompassed by Trumpet of Antithesis.

• Keystone is the foundation of All, The All, and THE ALL of the contents of Fiction, Narratives, and the Universe at the outermost closed uncollapsable definitive level where scale is meaningless as it has transcended names, terms, and essence - and in essence is incomprehensible and inaccessible.

Trumpet of Antithesis transforms "theoretical" terms in the expansion of the existential function, making it that the reality and unreality of the term and the contents of essence attached to it have vanished into nothing, containing it and thus holding it as a "theory". If a measurement is made - it yields an outcome, only one will occur, even though more than one could, so when it happens no measurement of the other theories can subsequently be made.

• Trumpet of Antithesis is all-encompassing and all-ever-transcendening the boundless range of possible and impossible values for the observable - in names, terms, and essence - and in essence that is unknowable.
• Trumpet of Antithesis makes it that transcendence is a theoretical impossibility in states that are in compliance with the "High" and the "Low", whereas to the Low, the High is always a theoretical impossibility.
• Trumpet of Antithesis contains all theoretical allegorical illustrations of the concept of the Omniverse.

Trumpet of Antithesis is the total all-encompassing expanse of all modes and attributes in connection to all theories of manifest phenomena/unmanifest phenomena that can be assigned values in Fiction, Nonfiction, Transfiction, Fanfiction, Metafiction, Patafiction, Interfiction, Personal Fiction, Impersonal Fiction, Incompatibilism Fiction, Impossible Fiction, Speculative Fiction, Xenofiction, Universal Genre, Universal Trope, Paratexts, Memetic Fiction, Transformation Fiction, and a priori and a posteriori Fiction.

• Trumpet of Antithesis encompasses all possible and impossible theoretical physical quantum possibilities.
• Trumpet of Antithesis encompasses all possible and impossible theoretical Metaphysical possibilities.
• Trumpet of Antithesis encompasses all possible and impossible theoretical Pataphysical meta-possibilities.
