Descent

The term descent refers to any authorized vertical translocation within the physical structure of the Tower, executed in accordance with a sanctioned Descent Protocol. The concept is distinct from simple downward movement, as it implies a procedural, documented, and often ritualized traversal between numbered floors, governed by the Directorate of Descent.

Procedural Framework

All legitimate descent is predicated upon the approval and activation of a specific Descent Protocol. A typical descent begins with the filing of Form L-17 "Request for Descent" with the Directorate’s Seventh Bureau, followed by a review of Proposed Descent Particulars. Upon approval, the designated protocol—such as Descent Protocol Delta-7-22 for general-purpose descent—is activated. The descending party, or Descendant, is then bound by the stipulations of that protocol for the duration of the journey.

Descent Protocols are categorized by class (e.g., Delta, Sigma) and enumerate permissible routes, required equipment, observational mandates, and reporting schedules. Contravention of an active protocol constitutes a breach of Concordance and may result in the suspension of descent privileges or reassignment of the Descendant to archival duties.

Classes of Descent

The Tower recognizes several formal classes of descent, each serving a distinct administrative purpose.

• Delta-class: Standard, general-purpose descents. Descent Protocol Delta-7-22 is the most frequently invoked example, used for routine transfers of personnel and materials between co-lateral floors.
• Sigma-class: Specialized descents, often of an exploratory or remedial nature. The Vellum Descent Sigma-1 is a canonical, though controversial, instance of this class.
• Guided Descent: A practice wherein the Descendant is accompanied by a certified Guide from the Directorate. The purpose is typically instructional or to ensure adherence to complex observational clauses.
• Recursive Descent: A rare procedural status invoked when the subject of a descent is itself a documented descent process. Under Recursive Descent, all Guided Descent protocols are automatically suspended.

Custody and Authority

Ultimate custodial authority over all matters of descent rests with the Warden of Descent, the appointed head of the Directorate of Descent. The Warden’s executive powers include the final approval or denial of descent applications and the issuance of emergency protocol overrides. The Directorate’s mandate is codified within the master document known as the Descent Protocols, though operational authority is decentralized among various bureaus, each managing a portfolio of active descents.

The physical originals of approved protocols are held in the Directorate’s central archive, with the Warden of Descent maintaining personal custodianship of the most sensitive Sigma-class documents, including the full set of Descent Protocols Sigma-1 through Sigma-9.

Controversies and Interpretive Disputes

The nature and limits of descent authority are perennially contested. A principal schism exists between the “Proceduralist” and “Cartographic” schools of thought within the Directorate.

• Proceduralists argue that descent is defined purely by adherence to a sanctioned protocol. They hold that a journey undertaken without a protocol, regardless of vertical displacement, is not a descent but merely “unauthorized falling.”
• Cartographers contend that descent is an intrinsic property of certain Tower spaces, and that protocols merely document pre-existing permissible routes. They cite anomalies where unplanned descents have occurred spontaneously in regions of high “axial torque,” as defined by the disputed Gradient of Ascent/Descent metric.

These disputes are frequently adjudicated—though rarely resolved—by reference to the often contradictory Third Concordance and Seventh Concordance.

Physical and Phenomenological Aspects

While descent is primarily an administrative category, it is associated with several consistent physical phenomena. Approved descent routes often exhibit a temporary stabilization of local gravity gradients and a perceptible thinning of inter-floor atmospheric resistance. Descendants frequently report a subjective lengthening of duration and a heightened clarity of archival memory during active protocol traversal. These effects are most pronounced during Sigma-class descents, leading some scholars to theorize that the protocol itself partially constructs the reality of the path it describes.
