The Unified Encyclopaedia
Thirty-three interlinked entries with chapter sources and reader-selected coverage.
First edition: people, places, species, institutions, objects and concepts from selected scenes in Books 1–21. This is a selective reference, not a claim to cover every appearance or every later development. Each entry declares its coverage by book. Interpretations are separated from what its cited scenes establish.

Archival imprints
Concepts · coverage through Book 19
An archival imprint is the format of Della Voss’s deposited verbal testimony. It is a personal record, distinct from the commissioned Memory House. A privacy protocol governs access; Sable explains its conditions when offering the Doctor the opportunity to hear the testimony.

Callum Dresh
People · coverage through Book 19
Callum Dresh is a junior archivist in Mnem’s City Memory Office. He has spent months sketching the Memory House to understand its unusual architecture. His notebook records that investigation, and he draws attention to the unexpectedly sparse catalogue entry for the building.

City Memory Office
Organisations · coverage through Book 19
Mnem’s City Memory Office employs Callum Dresh and manages archival records with depositors, dates and access conditions. Sable Orin acts as Senior Archivist. She says the Office has standing to coordinate a response for residents affected by the Memory House, although another administrator also claims a containment role.

Davan Orel
People · coverage through Book 21
Davan Orel specialises in temporal-fold cartography. Their record lists them as missing. When the travellers encounter them, Davan is investigating the fold and assessing removal of the probability suppressor. Their measurements and knowledge of the local hazards are essential to the proposed intervention.

Della Voss
People · coverage through Book 19
Della Voss is central to the Doctor’s deposited account of leaving her. She also filed her own verbal testimony on Vethara. Sable makes that separate account available under its access conditions. Hearing it is the Doctor’s choice, distinct from the technical work of resolving the Remanent.
Source: Book 19 · Chapter Two: How a City Remembers · passage 290
Fen
People · coverage through Book 19
Fen is a memory-layer in the Old Weave. She installs archival imprints and carries out transfers for depositors. Callum identifies her work when explaining how memories become part of Mnem’s archive.
Source: Book 19 · Chapter Two: How a City Remembers · passage 248
Gallifrey
Places · coverage through Book 7
The Time Lords’ home world is the setting of The Day Gallifrey Slept. Its last songbird has vanished unnoticed. That absence accompanies a wider investigation into suppressed memory, institutional control and Raven’s earlier life as Ravendael.
Source: Book 7 · Chapter One: Echoes Beneath the Dome · passage 4
MINO
People · coverage through Book 7
Memory Inference and Navigation Organism, a mechanical owl with archival and navigational functions. MINO gives this name on awakening from long-term stasis. Ravendael created him and equipped him to survive erasure until she remembered herself. He is capable of disagreement as well as analysis.
Source: Book 7 · Chapter One: Echoes Beneath the Dome · passage 16 · Book 7 · Chapter Two: The Girl in the Memory Cage · passage 385
MINO's right to leave
Concepts · coverage through Book 12
MINO accepts the invitation to remain as the Once and Future Owl on the condition that he can leave when called elsewhere. This voluntary arrangement follows the Council’s earlier demand for diagnostic reversion.
Source: Book 12 · Chapter Fifteen: The Once and Future Owl · passage 2114
Mnem
Places · coverage through Book 19
Mnem is a city of pale stone streets and buildings, with ash-barked trees and silver leaves beneath an overcast sky. Its archival institutions manage deposited memories and their access conditions. The Memory House lies in the Old Weave, amid an inhabited city affected by what emerges from it.
Source: Book 19 · Chapter One: The TARDIS Has Opinions · passage 55
Multiversal Stabilizer Hub
Places · coverage through Book 12
The Multiversal Stabilizer Hub is an anchor-point of the narrative structure. MINO describes it as a construct recalibrating stabilising harmonics. The Council of Owls exercises authority there and demands MINO’s diagnostic reversion when it recognises him as a stabilizer prototype.
Source: Book 12 · Chapter One: A Feather in the Gear · passage 31
Probability weighting
Concepts · coverage through Book 21
Davan describes probability weighting as the causal weight of a consciousness’s choices. The suppressor diminishes that function. Measurements establish the reduction, but cannot identify every past outcome that would have differed without it. The Doctor acknowledges that uncertainty when Raven considers the affected years.
Source: Book 21 · Chapter Ten — What the Silence Left · passage 954
Raven / Ravendael
People · coverage through Book 7
Raven’s earlier name is Ravendael. In Book 7, MINO identifies her as his creator and explains that she prepared him to survive erasure. Her mind also disrupts the attempt to remake her as a compliant Archivist, causing the extraction process to collapse.
Source: Book 7 · Chapter Two: The Girl in the Memory Cage · passage 385
Raven's navigational bearing
Concepts · coverage through Book 21
Raven proposes using her response to the fold’s causal topology to locate the suppressor. She has not deliberately navigated that way before and is uncertain of its precision. In the proposed journey she supplies the bearing, while Davan charts hazards, MINO tracks their position and the Doctor steers.
Source: Book 21 · Chapter Ten — What the Silence Left · passage 998
Recursive truth protocols
Concepts · coverage through Book 7
Ravendael built recursive truth protocols into MINO to help him survive erasure. MINO connects the safeguard to waiting for her and activating when she remembers herself. The exchange identifies its purpose and creator without describing its internal implementation.
Source: Book 7 · Chapter Two: The Girl in the Memory Cage · passage 386
Sable Orin
People · coverage through Book 19
Sable Orin is Mnem’s Senior Archivist. She explains the Remanent and the connection between the Doctor and the Memory House, offers access to Della’s testimony under its privacy rules, and plans a response for affected residents. Some details of the original deposit remain outside her knowledge.
Source: Book 19 · Chapter Two: How a City Remembers · passage 297
Serantha
Places · coverage through Book 19
After Mnem, the travellers visit temperate Serantha. They land in a park where paths run among old trees towards a lake. The nearby settlement is labelled simply the City on the TARDIS display. Raven checks the long local day as they settle into the visit.
Source: Book 19 · Chapter Eighteen: The Long Afternoon · passage 2230
Temporal folds
Concepts · coverage through Book 21
The fold investigated in Book 21 has navigable causal directions. Davan explains that its closure encodes an internal causal record into local history, limiting the time available to remove the suppressor. Navigation towards the past creates difficulties for the travellers’ ordinary instruments.
Source: Book 21 · Chapter Ten — What the Silence Left · passage 958
The compliant Archivist programme
Concepts · coverage through Book 7
An incomplete extraction loop attempts to return Raven to the narrative as a compliant Archivist. Her mind overwrites the reprogramming script, collapsing the process. The frame is then sealed. MINO recounts that resistance during the investigation of her past.
Source: Book 7 · Chapter Two: The Girl in the Memory Cage · passage 372
The Council of Owls
Organisations · coverage through Book 12
Seven masked figures identify themselves as maintainers of the weave’s harmonic resonance. They recognise MINO as a stabilizer prototype and demand his return for diagnostic reversion. When he refuses, they classify his refusal as a deviation.
Source: Book 12 · Chapter One: A Feather in the Gear · passage 49
The Daleks
Species · coverage through Book 11
The Daleks are organic mutants housed in armoured machinery. On Varnax, people also reuse Dalek material and imitate its symbols. An opened casing reveals organic remains; a separate trace indicates a recent command-class presence. The priests and scavenged equipment belong to the surrounding culture rather than constituting living Daleks.

The Doctor's pocket watch
Objects · coverage through Book 19
While Sable explains the Memory House’s continuing connection to its depositor, the Doctor repeatedly turns his watch inside his pocket. Raven recognises the gesture. In this exchange, his handling of the watch accompanies his difficulty receiving the information.
Source: Book 19 · Chapter Two: How a City Remembers · passage 269
The Eaters
Beings · coverage through Book 1
The Eaters unmake events and the lives dependent on them. The first appears through a rupture near the TARDIS console room, with an unstable form, and challenges the Doctor’s continued existence. The destruction that follows threatens people and civilisations by removing the conditions that allowed them to exist.
Source: Book 1 · Chapter Two: The Eaters of Time · passage 51
The Memory House
Places · coverage through Book 19
The Memory House is a commissioned, single-occupancy building in the Old Weave, sealed at its depositor’s request. It remains calibrated to his emotional signature. Its catalogue entry is unusually sparse. The Remanent develops from the archived material and acquires an appetite of its own.

The Multiversal Confluence
Places · coverage through Book 1
The dying edge of the Multiversal Confluence is the setting of the Doctor’s unification. A collapsing pocket reality endangers the TARDIS as stars and time lose their ordinary relations. Within that crisis, the Doctor uses the shard of the Moment during the convergence.
The Old Weave
Places · coverage through Book 19
Mnem’s oldest quarter contains unusually dense layers of memory-architecture. Callum’s map places the Memory House at its deepest point, without specifying a measured distance. Fen works in the quarter, transferring and installing archival imprints.
Source: Book 19 · Chapter One: The TARDIS Has Opinions · passage 142
The probability suppressor
Objects · coverage through Book 21
The probability suppressor is a manufactured device placed in the fold. It diminishes probability signatures across an affected region. Davan distinguishes the material age of the device from when it was installed. Removing it is subject to the fold’s closure conditions and their effect on local history.
Source: Book 21 · Chapter Ten — What the Silence Left · passage 954
The Remanent
Beings · coverage through Book 19
The Remanent develops from the material archived in the Memory House, acquiring a presence and appetite separate from the original account. It echoes words imperfectly, including Della’s name. Sable distinguishes its distorted reproductions from Della’s separately deposited testimony.
Source: Book 19 · Chapter Two: How a City Remembers · passage 267
The shard of the Moment
Objects · coverage through Book 1
A shard of the Moment participates in the Doctor’s unification. He places the relic in the heart of the TARDIS console during the crisis at the Multiversal Confluence. Its role in that event connects paradox, memory and choice.
The sonic screwdriver
Objects · coverage through Book 1
The Doctor’s new sonic screwdriver is bronze and silver with a crystalline tip. He retrieves it from a case whose biometric locks recognise his combined identity. The instrument is part of his equipment from Book 1 onward.
Source: Book 1 · Chapter Two: The Eaters of Time · passage 46
The TARDIS
Objects · coverage through Book 21
The Doctor’s ship travels through time and space and responds to the conditions of a journey. During the fold investigation, the Doctor recognises her discomfort. Reaching the destination requires Davan’s charting, Raven’s bearing, MINO’s tracking and the Doctor’s steering.
Source: Book 21 · Chapter Ten — What the Silence Left · passage 993
The Unified Doctor
People · coverage through Book 1
The Unified Doctor emerges when his earlier Time Lord identities converge into one consciousness. The visible echoes disappear as the convergence ends. He inherits those lives, with their memories and habits, while remaining responsible for his present choices. Integration leaves him capable of uncertainty and error.
