Guild of Horizon Chasers

The Guild of Horizon Chasers is a regulatory body within the Theoretical Jurisprudence Guild, tasked with adjudicating claims of architectural non-existence in the Tower’s most distally referenced spaces. Its primary function is to determine when a described but physically unverified floor, aperture, or void may be officially declared a ‘Horizon’—a locale that exists solely as a referent within the archive, with no corresponding concrete reality, yet which accrues legal and logistical obligations.

Jurisdiction and Definition

The Guild’s authority derives from the Third Concordance, Annex Gamma-7, which defines a Horizon as "any spatial designation, formally catalogued, for which all attested points of ingress or egress are themselves catalogued under contradictory or mutually annulling protocols." In practice, this often involves floors cited in expedition logs that subsequent, better-equipped parties cannot relocate, or stairwells documented in one annex of a Concordance and explicitly redacted in another. The Guild does not seek to prove or disprove a Horizon’s physical existence; rather, it evaluates the sufficiency of the citation network supporting its procedural existence. A successful Horizon declaration triggers a cascade of administrative actions, including the issuance of Notional Tax assessments to adjacent floors and the mandatory appointment of a Provisional Librarian for the non-existent space.

The Chasing Protocol

The core activity of the Guild is the Chasing Protocol, a multi-stage bureaucratic process. Phase One involves the petitioner, often a Scrollwright or a Formal Cartographer, submitting a Docket of Vanishing Evidence. Phase Two sees a team of Guild-appointed Reflectors and Constructivists attempt to reconcile the contradictory references. If reconciliation is deemed impossible (per Guild Standard 88-Ω-12), Phase Three initiates a Ceremonial Chase: a delegation ascends or descends to the last verifiable coordinate, reads the relevant citations aloud into the unreachable space, and files a Certificate of Unanswered Summons. This certificate is the final prerequisite for a Horizon Ruling.

Notable Horizon Rulings

Ruling 301: The Whispering Stacks of Floor Ξ-117

Declared a Horizon in 12,443 AT (After Tower), following the discovery that its sole documented access spiral was described in the Compendium of Unheeded Dissents as "ascending clockwise," while the Guild of Stonemasons' bedrock core samples for that sector proved all natural spirals there twist counter-clockwise. The ruling compelled the Inter-Guild Logistical Network Guild to schedule notional supply drops every third Tuesday.

Ruling 588: The Garden of Hypothetical Pollinators

This extensive biome, referenced in Horticultural Guild Standard 114-Δ-7b, was challenged when the Guild of Groundskeepers could not locate the requisite "ambient luminescence of a speculative wavelength." The Horizon Chasers ruled in favor of non-existence, but the Margin Commentators Guild successfully appended a dissent arguing that the garden’s hypothetical state was a more perfect form of existence than a verified, but mundane, one.

Inter-Guild Relations and Disputes

The Guild’s work is a persistent source of tension. The Index of Forthcoming Inexistence relies heavily on its rulings to update its predictive registers. Conversely, the Skeptical Cartographers’ Guild views Horizon Chasing as a tautological exercise, arguing it “manufactures absence where there is merely insufficient data.” The most protracted conflict is with the Guild of Oneirometric Cartographers, whose maps of dreamt spaces often become subjects for Horizon petitions. The Chasers maintain that dreamt cartography constitutes a “pre-citational state” and cannot form the basis for a Horizon, a stance formalized in Ruling 712, which the Oneirometric Cartographers have never accepted.

Theoretical Schism: Consequentialist vs. Nominalist Horizons

A fundamental doctrinal split persists within the Guild. The Consequentialist wing, led by Senior Chaser Aris Thorne, holds that a Horizon’s legitimacy is measured by the tangible bureaucratic consequences it generates (e.g., Notional Taxes, provisioning schedules). The Nominalist wing, following Emeritus Chaser Kaelen Voss, argues that a Horizon is pure referent, and its consequences are merely epiphenomena; its existence is validated the moment it is coherently cited in two non-identical documents, regardless of outcome. This schism directly influences rulings, with Consequentialists favoring declarations that simplify logistical networks, and Nominalists advocating for a more expansive, proliferation-friendly approach. The dispute is currently lodged with the parent Theoretical Jurisprudence Guild for mediation, docket number TJG-4492-A.

Logistical Footprint

Despite regulating non-existent spaces, the Guild maintains a substantial material presence. Its primary Guild Hall occupies the entirety of Floor 20,001 (named "The Vestibule of Unfulfilled Approaches"), a space chosen for its single, heavily documented entrance. It consumes more ceremonial parchment and sealing wax than any guild of comparable size, and its reliance on the Inter-Guild Logistical Network Guild for the delivery of actual supplies—as opposed to the notional supplies it schedules—is a frequent point of audit contention. The Guild employs 147 certified Chasers, 89 clerks of citation, and maintains a dedicated liaison office to the Realized Absence Guild, though the nature of their cooperative efforts is classified.
