The Unremembering

Protocol U-3: interruption of Tindalosian observer correlation

Circulation restriction. No practitioner may keep a complete copy of this protocol after performing it. Distribute the sections among the attending personnel and assemble them only once the subject is in isolation.

Earlier editions told the attending physician to memorize the procedure. That instruction killed the people who followed it.

Purpose

You run the Unremembering when a living witness has picked up a Tindalosian scent, but the outside contamination is still contained enough that removing that one person’s record might drag the correlation back under the manifestation threshold.

People call it memory erasure. That name is worse than wrong, it is misleading in a way that gets practitioners killed. A person can be completely unable to recall an event and still carry its physical memory trace, its emotional conditioning, the little procedural habits it left behind, and every thread tying them to external records. The subject forgets ever seeing the Hound and goes right on rounding off corners, flinching at a particular smell, and waking a few seconds before the plaster cracks. What you are left with is someone with no conscious memory of the encounter who remains, physically, a perfectly good piece of evidence for it.

Clinical basis

Episodic memory does not sit in one place. It spreads the sensory detail, the location, the emotion, the interpretation, and the autobiographical framing across a web of connected neural systems, and pattern completion can rebuild the whole episode from a single corner of it. Worse, for our purposes, is that retrieval changes the memory. Pull a memory up and it goes briefly labile, needing to reconsolidate before it sets again. Human studies have managed to disrupt reactivated episodic memories inside that window; animal work has shown an engram sitting physically intact right through an apparent retrograde amnesia, waiting to be switched back on.

The distinctions here are load-bearing, and mixing them up is how you fail:

• Forgetting. Recall just fails, the ordinary way.
• Retrieval blockade. The stored representation is still there; the usual cues can no longer reach it.
• Reconsolidation disruption. A reactivated memory fails to set again properly.
• Engram destruction. The physical encoding itself is gone.
• Causal excision. Neither the subject nor any reachable external record holds enough structure to rebuild the encounter.

What Protocol U-3 can reliably attempt is the middle pair: retrieval blockade and reconsolidation disruption. Anyone who tells you it destroys an engram is guessing. Anyone who tells you it removes external records is a fool.

Indications

Proceed only when every one of these holds:

1. The subject is a primary or secondary witness to Tindalosian contact.
2. The subject is still a major contributor to the Scent Track.
3. You have inventoried the durable external records.
4. No public or self-replicating record exists.
5. You can enforce a post-procedure quarantine.
6. The attending personnel understand that finishing the protocol successfully may leave them as the strongest surviving records.

Do not run it during an active manifestation unless the treatment chamber has been geometrically prepared first. Reactivation makes the scent stronger before it makes it weaker, and that early spike is where people die.

The procedure

Phase I: Inventory

Before you go anywhere near the subject’s memory, find everything that could put it back:

• Other witnesses
• Journals and letters
• Photographs, recordings, telemetry
• Medical documentation
• Search and travel histories
• Defensive changes made to buildings
• Repeated phrases, drawings, compulsive habits
• Objects tied to the encounter

The inventory you just made is itself a new record. Split it across personnel. No single person should be able to see the whole network.

Phase II: Isolation

Put the subject in a room with no untreated geometric discontinuity anywhere in it. Take away personal objects and any communications you do not control. Once reactivation begins, do not let them sleep; hippocampal replay can strengthen the very memory you are trying to loosen, or quietly reorganize it into something harder to reach. The subject must not know what the treatment is actually for. Anticipation breeds rehearsal, and rehearsal is exactly what reinforces the retrieval pathways you need to cut.

Phase III: Controlled reactivation

The memory has to be live before you can interrupt its reconsolidation. Use the smallest cue that produces definite recall:

• The odour that was present during manifestation
• A fragment of the original room
• One true sentence from the witness’s own account
• A drawing with the correct angle in it
• The name Tindalos

Do not lead with the full account. Push the cue strength up only until the subject clearly retrieves. This is the most dangerous stage of the whole procedure. For a few minutes the subject is a sharper record than they were when you started, so raise the Scent Track by 1. And if a stable manifestation begins now and you abort, you hand the memory back freshly reconsolidated and tougher to touch than before you ever started.

Phase IV: Destabilization

Have the subject retrieve the encounter while you feed in controlled prediction error: something that proves the remembered version is incomplete or contradicts itself. You are not trying to convince them it never happened. You are trying to stop them rehearsing a fixed, polished narrative. Done right, the memory drops into its labile interval, and this is where the occult half of U-3 happens: you sever the angular relationships holding the active representation together before the network can set again. Aim at the connections, not the content. Content grows back.

Phase V: Sacrifice of anchors

The central memory can usually be rebuilt from the material around it, so you have to take the material around it. Name five anchors:

1. Person: someone present, or told afterward.
2. Place: where contact happened.
3. Object: an apparatus, a document, a defensive tool.
4. Sensation: an odour, a sound, a pain, a visual detail.
5. Consequence: something they did because of the encounter.

At least three of these have to be made inaccessible, and each one you pull takes a chunk of neighbouring autobiography with it. The subject may lose the friend who saved them, the reason they made a journey, the fact that a treasured object was ever theirs, a whole season of their life, the origin of a skill they use every day. Those surrounding losses are not collateral. They are the mechanism. They are what stops pattern completion from quietly rebuilding the middle.

Phase VI: Verification

Test separately for explicit, emotional, procedural, and semantic residue.

A subject who passes explicit recall but fails the rest is amnesic. Amnesic is not clean.

Phase VII: Quarantine

Keep the subject away from every known external record. Withdraw the personnel in reverse order of their exposure, and let nobody who ran the reactivation stay on for long-term care. Do not explain the gap you left in their memory. An explanation is just a scaffold somebody can climb to reach the rest.

System-neutral game procedure

Give the affected character five Memory Anchors: Person, Place, Object, Sensation, Consequence.

During the Unremembering:

1. Raise Scent by 1 during reactivation.
2. The group picks three anchors to sacrifice.
3. For each one, permanently remove or rewrite something specific in the fiction.
4. Test the two anchors left standing. On a failure, one becomes a hidden Residual Anchor the players are not told about.
5. Drop the subject’s contribution to Scent by 2. If they were the only viable record, the whole track can fall to 0.

A Residual Anchor wakes up when the character runs into it in play. First exposure brings dreams and compulsions. Second restores fragments. Third gives the whole memory back and raises Scent by 2 on the spot. Do not price any of this as generic sanity loss. Take away relationships, competencies, promises, and pieces of identity the table has already watched matter.

Failure modes

The body remembers

The facts are gone, but the autonomic fear stays. The subject cannot tell you why square rooms give them tachycardia, or why they keep waking with plaster under their fingernails.

The hand remembers

Procedural memory outlives the episode. The subject draws protective curves without noticing, wrecks cameras, or simply will not write certain words.

The word remains

The episode vanishes and leaves one semantic splinter behind: They come through angles. The subject carries it as a fact with no source, and it frightens them more for having none.

The physician becomes the archive

The treatment goes perfectly. To run it, the physician had to draw out, organize, and fully understand every important feature of the encounter. The Hound lets the patient go and turns toward the cleaner record, which is now sitting in the doctor’s own head.

The false memory leaks

A mundane replacement story papers over the gap, but its seams do not quite line up, and the wrongness invites exactly the investigation you were avoiding. Correct the false memory and you have reconstructed the real one.

Sleep restores the path

After treatment, overnight replay quietly reconnects the anchors you left alive. The subject wakes knowing only one thing with total certainty: the corners have to be covered, now.

Scenario hooks

Discharge

A successfully treated patient goes home to a spouse who never made it onto the record inventory. The spouse, gently and out of love, begins handing them back their missing past.

The Ward

An institution full of calm patients, all with the same shape of hole in their autobiographies. Staff turnover is brutal. Every clinician who leaves dies in a room with fresh cracks in the plaster.

Inheritance

The investigators are left five sealed boxes by a dead relative, each entrusted to a different executor. No box is dangerous by itself. The will requires them to be brought together and their contents assembled.

The Last Practitioner

The only person still able to perform U-3 has run it on herself after every single treatment. She has the skill and no memory of acquiring it, no memory of her patients, and no idea why her own notebooks warn her, in her own hand, never to trust her earlier handwriting.

Addendum: why protection never lasts

The Unremembering strips out enough accessible structure that the subject temporarily stops functioning as a recoverable record, while the encounter and all its other consequences carry on existing. External evidence can undo that. So can surviving engram structure, a sensory cue, procedural residue, or one more witness turning up. The more completely the procedure protects the subject, the more of the person’s surrounding life it has to burn down to do it. The whole aim is to leave behind someone from whom the Hound can no longer be rebuilt, and the cost of that is most of who they were.

—

The patient sat quietly under an untreated corner and did not look up. Her pulse held steady when the physician uncorked the vial of blue residue. She did not know the photograph, or the room, or her own handwriting. The procedure had worked on the patient. Then the physician closed a file that held the most complete surviving account of the encounter anywhere in the world, and above him, the plaster cracked.
