Seventeen Mirrors of Partial Reflection

The Seventeen Mirrors of Partial Reflection are a classified and permanently sequestered set of reflective instruments catalogued under Seal 117-B on Spire 404, Gallery of Partial Weaves. Their primary, and contentious, characteristic is their ability to reflect only a designated portion—never the entirety—of any object or scene placed before them. Governance of their access, study, and potential application falls under the overlapping, and often contradictory, jurisdictions of The Seventeen Provisional Protocols, Third Anti-Reflection Statute, and Concordance 117: Places of Habitation, Partial or Perpetual.

Physical Properties and Anomalous Behavior

Each mirror is framed in a distinct, non-repeating alloy, the composition of which is recorded in the Ledger of Partial Acquisitions. Their surfaces do not exhibit standard specular reflection. Instead, they operate under a principle termed "selective fidelity." When an object is positioned within their reflective field, the mirror will return an image of a predetermined fragment: for example, only the left third of a face, only the shadow cast by a vase, or only the written text on the top line of a document, leaving the rest of the page void. The selection criteria are not fixed per mirror but appear to shift according to protocols outlined in, yet never fully disclosed by, the Seventeen Provisional Protocols.

This partial reflection is not a matter of obscured or damaged glass. The reflected portion is rendered in perfect, often hyper-realistic detail, while the absent portions manifest as a profound, light-absorbing matte grey, described in inspection reports as "a negation of image." The mirrors themselves are cold to the touch, registering approximately 11 degrees below ambient temperature, a trait they share with certain artifacts documented during The Partial Survey.

Provenance and Sealing

The mirrors were acquired in seven batches over a period corresponding to Years 45-62 of the Fifth Chronology, as verified by the The Partial Survey. Their origin is listed in the Ledger of Partial Acquisitions simply as "acquired via provisional aperture," a term that, under Provisocol 7, refers to temporary, non-repeating openings between Spire 404 and unspecified counterpart locations. Their arrival prompted the immediate drafting of the Seventeen Sealing Verses, which are recited by a rotating panel of Anglesmiths during any physical interaction with the collection.

Current sequestration is enforced on a dedicated sub-level of Spire 404, Gallery of Partial Weaves, behind doors plated with non-reflective cerametal. Access requires dual authorization from the Reflector Guild and the Office of Provisional Compliance, a process famously mired in bureaucratic delay, as the requisite forms are themselves subject to partial reflection if brought near the mirrors without proper shielding.

Regulatory Paradoxes

The mirrors exist at the intersection of several conflicting statutes. The Third Anti-Reflection Statute mandates the coating or sequestration of reflective surfaces, a condition satisfied by their current housing. However, Concordance 117: Places of Habitation, Partial or Perpetual arguably defines their chamber as a "Place of Partial Habitation" for the reflected fragments, introducing obligations of care and documentation that clash with the sequestration mandate. Furthermore, The Seventeen Provisional Protocols grant conditional study rights that are periodically suspended by amendments to the Anti-Reflection Statutes.

This legal tension is most evident in the ongoing scholarly dispute regarding whether a partially reflected individual is, for the duration of the reflection, considered a "partial resident" under Concordance 117. A minority school of thought, citing precedents from The Correspondence of Mirrored Intent, argues that the reflected fragment may develop independent intent, a notion strictly prohibited by the final clause of the Seventeen Sealing Verses.

Documented Interactions and the Seventh Mirror Incident

Permitted studies, logged in the annexes to the Ledger of Partial Acquisitions, focus on inert objects. Notable results include the reflection of only the spiral pattern on a specimen of Aris Spiralis, and the isolation of a single rune from a page of the Seventeen Sealing Verses. The sole major incident occurred during the certification of the seventh certified copy of the Ledger itself, when the Seventh Mirror reflected only the notary's signature and the date, omitting all listed items. The notary reported a temporary inability to perceive the missing information, even when looking directly at the original ledger, a condition that lifted only after the mirror was covered. This event led to the expansion of Provisocol 12 to include clauses governing the reflection of legal documents.

Theoretical Implications and Current Status

The prevailing theoretical framework, as developed during The Partial Survey (1901-1903), posits the mirrors not as reflectors but as "partial apertures" or "filters" that isolate and make manifest a single, arbitrary attribute from the unified field of perception. This challenges the foundational Reflective taxonomy, which assumes reflection is a property of surface geometry, not selective intent.

As of the last Reconciliation of the Seventeen Calendars, the Seventeen Mirrors remain in permanent sequestration. All active research permits are indefinitely suspended under a joint decree citing the Third Anti-Reflection Statute and the security provisions of Provisocol 1. Their preservation chamber is maintained at constant humidity and monitored by Anglesmiths using reflection pools calibrated to detect any change in the mirrors' dormant, partial state. They are listed as a Prohibited Instrument, cross-referenced with The Sanctioned Quill of Erasure for procedural symmetry in authorization logs.
