Archive of Unrealized Descents

The Archive of Unrealized Descents is a repository on Floor Xi-77 holding denied Descent Particulars: the complete documentary residue of vertical expeditions that were proposed, costed, provisioned, and refused. It is not to be confused with the Archive of Unhad Dreams on Floor Omicron-12, which holds material of a different order, nor with the Descents Practice itself, whose unauthorized expeditions the Archive exists to document. Its founding instrument is Concordance 7-Xi-22, 'On the Custody of Unrealized Potentials' which administers custody of potentials that were formally entered and never exercised.

The Archive is read principally by the School of Predictive Curation, which maintains a small reading room at the eastern stair-head and which has published a running account of the holdings since 1794.

Holdings

The Archive's unit of account is the Particular, a bound dossier containing the Descent Party's manifest, the proposed route, the objections raised against it, and the denial instrument itself. A Particular is complete when the objection and denial are of the same date; incomplete Particulars are held in the Pending Stack and may not be cited.

At the last general count the Archive held 214,908 Particulars, of which 14,002 were Pending. Acquisition is by transfer from the Directorate of Descent, which is obliged to surrender denied applications within one hundred days under Clause XVII.4. The Directorate has missed this deadline in every year since it was imposed, and in 1837 surrendered 40,000 Particulars in a single cart, undated and unsorted. These are known as the Cart of '37 and remain the Archive's largest single unprocessed accession.

The Vellum Problem

Particulars were, until 1811, inscribed on Vellum of the standard cut used for Vellum Descent certification. This created a custody conflict of long standing. Because the Master Survey of Unrealized Architectonics records the material properties of holdings according to the principle of Codicillary Inertia, a denied Descent Particular on the same vellum as a granted one was held, in some readings, to inherit the granted one's spatial claims.

The practical result was embarrassing. Between 1802 and 1809 a series of Particulars denied for want of headroom were found to have deposited faint corridors in the eastern stair-well, and one of them — Particular 8,441, a proposal to descend to Floor Q-3 — produced a landing so convincing that a porter swept it for eleven years.

"The landing was not there. The landing was, however, subject to a Particular, and a Particular subject to custody is a thing the Tower keeps. The distinction is not visible from the stair."

— Tract on Latent Administration, §19

From 1811 Particulars were rebound on a coarser stock under a ruling of the Senior Librarian of Intent, and the corridor deposits ceased within a decade. The Archive retains the original vellum covers, which are not to be opened in the eastern stair-head reading room, and are not to be removed from the building.

The Blank Particulars and the Schism of Unrealized Holdings

The Archive's most contentious holdings are 311 Particulars filed with no applicant named. Depot records show only the receiving clerk's initials and the word "declined." The clerks' guild maintains that these are clerical omissions, entered against a party who failed to inscribe a name, and therefore without standing. The School of Predictive Curation maintains that they are withheld from public view by the terms of the denial.

The question is the local form of the Schism of Unrealized Holdings, and the Archive's Custodial Register for Unrealized Spaces records its own position on the matter four times, in four different hands, in the years 1822 through 1826. The Register's Personnel Annex has logged them as "unreconciled" since 1827 and, by the present writer's inspection, has stopped trying.

Administration and the Velocity Dispute

The Archive is administered in three statistical windows, which the Directorate of Descent has claimed since 1824 to constitute the Three-Velocity system and the Archive itself to constitute nothing at all. The claim is a recurring one. Under Administrative Velocity the Archive's rate of accession is compared against the Directorate's rate of denial, and the Directorate has twice argued that its denials outrun the shelves, and that the Archive is therefore obliged to accept Particulars it has not been sent.

The Archive rejects this. It holds that velocity is not a property it is required to exhibit, and that a denial not surrendered within one hundred days ceases to be a descent and becomes a rumour, which the Tower does not file. The Directorate's Ledger of Unrealized Events, Vol. 117 contains its counter-argument at length, annotated in a hand not its own.

Notable Holdings

• Particular 8,441 — Floor Q-3; the landing dispute (1803–1814).
• The Cart of '37 — 40,000 undated Particulars, unsorted; not available for consultation.
• Particulars 3,102–3,412 — the 311 blank filings; restricted by the terms of the denial.
• Particular 77,002 — the only Particular denied by the applicant; the applicant's reasons are entered as "private."

The Archive shares a vestibule with the Incinerator of Lapsed Potential, and the two are often cited together in the teaching of the Descents Practice. The practice, in its formal registers, distinguishes them thus: the Incinerator destroys a potential, and the Archive keeps one. Neither office has been able to establish what the intermediate station does, and the corridor between them is closed for repainting.
