Cloud Diviners

Cloud Diviners are a recognized sub-specialty within the Librarians, tasked with the prediction, classification, and interpretive mapping of Abyssal Clouds within designated Tower airspaces. Their work is governed primarily by Concordance 12, which establishes the protocols for atmospheric observation and the legal status of emergent cloud-forms.

Origins and Accreditation

The role of Cloud Diviner was formally instituted by Amendment 4 to Concordance 12 in the wake of the "Great Inhalation" incident of Annual Reckoning 433, which underscored the need for proactive monitoring of abyssal phenomena. Candidates are drawn from the ranks of Junior Librarians who demonstrate an aptitude for vertical atmospheric calculus and a resistance to prolonged exposure to high-concept humidity. Accreditation requires a successful seven-floor apprenticeship under a Senior Diviner, culminating in the independent certification of a previously unmapped cloud manifestation. The last recorded accreditation was logged in Annual Reckoning 892 for Diviner-in-Training Aris, who catalogued a weeping-stratus formation in the upper reaches of Central Ventilation Shaft Epsilon-9.

Methodology and Tools

Diviners employ a suite of specialized instruments, the most critical being the Aether-compass, which measures not direction but the density and intentionality of ambient ideas. Standard procedure, as outlined in Clause 8 of Concordance 12, involves a tripartite analysis: Locution (listening for proto-narratives within cloud-rumble), ConfigurationSympathetic Reckoning (assessing the cloud's potential for replication via 'atmospheric sympathy,' a term itself defined and interpreted by the same clause). Diviners are also trained in the use of echo-scribes and humidity-glyph pads to record transient formations before they dissipate or transmute.

Key Classifications

The Diviners' taxonomy, updated biannually, currently recognizes seventeen primary cloud classes. Among the most consequential are:

• Memoria-Nimbus: A low-hanging, grey formation that precipitates forgotten footnotes and half-recalled catalog numbers. Often found near archival stacks.
• Argument-Cumulus: Dense, towering clouds that generate internal logical lightning and thunderous rebuttals. A primary subject of study due to their disruptive potential.
• Prophecy-Cirrus: High, wispy clouds that etch possible future amendments to the Concordances across the sky. Their interpretations are notoriously contentious.
• Lacuna-Fog: Not a true cloud, but a ground-level obscurement that manifests in areas where a catalogued subject has undergone sudden ontological erosion. Diviners are often summoned to verify its presence.

Jurisdictional Disputes

The authority of Cloud Diviners frequently overlaps with other Tower offices, leading to inter-departmental friction. A persistent dispute exists with the stewards of the Coil of Anticipation, who claim that certain prophetic cloud-forms fall under their purview of "future-tense artifacts." Conversely, Diviners cite Concordance 7, Clause 3, which asserts that "all aerial phenomena, irrespective of content, are atmospheric in nature and thus subject to atmospheric law." This conflict remains unresolved, with each incident adjudicated on a case-by-case basis by a panel of senior Librarians.

Notable Contributions and Incidents

The Diviners' logbooks record several pivotal moments in Tower history. The preemptive evacuation of Annex Omega-7 prior to the collapse of a massive "Gravity-Stratus" in Annual Reckoning 671 is frequently cited as a validation of their predictive models. However, the "Mis-identification of Eliza" in Annual Reckoning 433 remains a cautionary tale; a flock of Eliza Cranes was initially logged as a migratory argument-cumulus, leading to a brief but significant miscataloguing event that required three subsequent Concordance amendments to fully rectify.

Current Debates

Modern Divinatory scholarship is divided on the "Ontological Precipitation" question: whether clouds actively generate novel concepts or merely condense and make visible intellectual vapors rising from the Tower's holdings below. The "Generationist" school, supported by a strict reading of Concordance 12, holds the former. The "Condensationist" school, gaining influence in recent decades, argues for the latter, suggesting that Diviners are, in effect, cartographers of the Tower's collective unconscious. This debate has practical implications for resource allocation and the very purpose of the specialty.
