Department 8 Assessment

CLASSIFICATION: RESTRICTED — PARTIALLY DECLASSIFIED

DEPARTMENT 8

WHITEHALL, LONDON

Assessment Date: July 2024

RE: Blackthorn Manor Containment Status

Executive Summary

Historical assessment complete—Margaret Blackthorn's preservation strategy recognized as sophisticated containment continuation system designed to maintain Walter's original framework while transferring operational responsibility to Department 8 through carefully staged legal transition. Current operation benefits from decades of preparation, though complete understanding of system only recently achieved through Watcher communication.

Property Status

Threshold Holdings Ltd. (Department 8 special purpose vehicle) acquired property in 2015 following systematic monitoring under Margaret Blackthorn's preservation framework. Research facility designation provides operational cover for permanent containment team.

Alignment Assessment

Current astronomical instruments include custom modifications measuring frequencies outside standard scientific parameters. Observatory monitors the approaching alignment Walter predicted—a 157-year cycle when the Pleiades aligns with seven terrestrial points simultaneously, creating period of maximum dimensional thinning. Next critical alignment: Spring 2025. The Opener will have greatest potential to fully manifest during this window.

Entity Classification

THE WATCHERS: Seven entities existing partially in our dimension. Not hostile—assessed as dimensional refugees cooperating with containment to prevent greater threat.

THE OPENER: [REDACTED] — Entity from Watchers' realm seeking to collapse dimensional boundaries permanently. Primary containment target.

September 15, 2026. Following successful implementation of modified containment protocols during 2025 alignment crisis, Department 8 has established permanent research division dedicated to Blackthorn architectural principles. The Watchers remain present within controlled environmental parameters, functioning as interdimensional intermediaries rather than security threats. This document represents Level Alpha classified information—reader now incorporated into Blackthorn awareness protocol.

Department 8 - Threshold Monitoring Division

Document Reference: D8/TM/1942/BM-007

1. PURPOSE

This document establishes protocols for the monitoring and containment of Site BM-001 (Blackthorn Manor, Northumberland) following the evacuation of ██████████████ on 21 March 1942.

2. BACKGROUND

Lies. They knew about the site since 1916 at least. -MB

Site BM-001 was identified as a Category 7 Threshold Location following the ████████ Incident of March 1942. The site demonstrates persistent dimensional instability centred on the structure designated "East Wing" and the subterranean feature designated "████████".

Previous containment was maintained by the Blackthorn family under terms of an agreement dating to ████. Following the death of ████████ Blackthorn in 1941 and the incapacitation of ████████ Blackthorn during the March 1942 event, Department 8 has assumed monitoring responsibility.

3. NATURE OF THREAT

The entities designated ████████ (colloquially "The Watchers") exist in a state of partial manifestation within the dimensional interface created by ████████████████. Under normal containment conditions, their influence is limited to:

Auditory phenomena (whispers, voices) within 50m radius of primary aperture
Visual phenomena (shadows, reflections) during specific astronomical alignments
Cognitive influence on individuals with prolonged exposure to ████████

Complete manifestation would result in ████████████████████████████████████████████████████████████████████████████████████

4. CONTAINMENT PROTOCOLS

4.1 Physical access to Site BM-001 is restricted to authorised personnel only.

4.2 The structure designated "The Apparatus" in the east wing attic must be maintained according to specifications detailed in Appendix ██.

4.3 Ritual maintenance schedules established by the Blackthorn family must be continued. See Appendix ██ for procedures.

4.4 Any breach of the dimensional interface must be reported immediately to ████████████████.

4.5 Personnel exhibiting signs of ████████ contamination must be isolated and processed according to Protocol ██.

5. RELATED SITES

Site BM-001 is one of ██ Category 7 Threshold Locations currently under Department 8 monitoring in the United Kingdom. Related sites include:

████████████, Cornwall
████████████, Yorkshire
████████████, Scotland
████████████, Wales

Coordination between sites is essential during periods of elevated dimensional activity, particularly during ████████ alignments.

Archive Note: This document fragment was obtained through FOI request by the Preservation Society in 2001. The Ministry of Defence confirmed the existence of "Department 8" but declined to provide information about its current activities or the nature of "Threshold Locations."

The document confirms government awareness of unusual properties at Blackthorn Manor and suggests an ongoing monitoring programme. The reference to "ritual maintenance schedules" aligns with Margaret Blackthorn's annotations regarding family duties.
