Enchiridion of Invocation & Control – Foundry Campaign Compendium

I want to be careful about how I introduce this text, because texts like this have a way of being introduced poorly, either with sensationalism that makes them sound more dramatic than dangerous, or with dry academic neutrality that makes them sound safer than they are. The Enchiridion of Invocation and Control is a practical manual, exhaustively detailed, for compelling things to come to you that would not otherwise do so, and then compelling them to do what you want while they are here. Every method described in it works. I know this because the Ncuti of the Magaambya have a separate text devoted entirely to cleaning up after practitioners who used this one.

The author does not identify themselves. The voice throughout is professional, assured, and entirely devoid of the moral hesitation that most people would feel while writing certain sections of this book. Reading it at length produces the specific discomfort of realizing that the person who wrote it was not disordered or desperate or corrupted into their perspective. They simply did not share the assumptions about consent and personhood that most readers bring to the question of whether you should summon something sentient and then force it to do things. The absence of those assumptions is not stated. It is simply evident, the way a missing wall is evident, by what is not there.

Invocation, Summoning, and the Entities Involved

The text distinguishes between invocation, which creates a conduit to an entity while it remains on its own plane, and full summoning, which brings it into the material world in a form capable of physical action. For entities of significant power, the author recommends invocation as a preliminary step, not from ethical concern but because summoning something ancient and capable before establishing any relationship is, as the failure mode chapters document with unsettling specificity, a very large gamble.

For lesser entities, sprites, bound spirits, minor elementals, interstitial beings that exist in the spaces between planes, the author recommends skipping invocation entirely and summoning directly, on the reasoning that anything small enough to be summoned without preliminary contact is small enough to be managed if it goes wrong. I want to note that this reasoning, while internally coherent, rests on a definition of managed that I find troubling. A practitioner who regards the involuntary displacement of a minor sentient entity as an acceptable cost of management has already made a moral decision that the text treats as obvious rather than significant.

The Enchiridion makes no distinction between summoning a minor elemental and summoning a rock. Both are resources in the author’s framework, the elemental distinguished from the rock only by its capabilities. The summoning of lesser entities is described with the same procedural tone as the measurement of reagents: quantities, durations, binding geometries, disposal methods. Disposal methods. I have encountered practitioners who defend this on the grounds that lesser entities do not experience distress in ways comparable to mortal beings. I find this argument worth taking seriously and ultimately unconvincing. The entities described in the relevant chapters respond to pain stimuli, attempt to resist binding, and demonstrate unmistakable preference for not being dissolved. The author never considered the question at all.

The text’s moral architecture rests on a single premise: that the ability to compel a thing is sufficient justification for compelling it. Everything else follows from this, and the text is, in this sense, very coherent. Its coherence is precisely the problem.

Methods of Control and Compulsion

The compulsion framework chapters are the most technically impressive section of the text and the part most likely to cause a reader with any ethical grounding to set the book down for a period.

Physical binding uses specific geometric arrangements, materials, and energy configurations to constrain an entity’s physical presence. It confines the body, not the mind, and the author notes with care that entities of sufficient cognitive capability can act on the world through means other than physical presence, requiring additional framework chapters for those cases.

Will compulsion is the text’s most disturbing contribution. The author describes methods of applying pressure to an entity’s cognitive architecture that force behavioral compliance without obtaining consent, exploiting structural vulnerabilities specific to each entity type to create conditions under which the entity cannot choose non-compliance regardless of preference. The author compares this to a lock: not asking the door to open, but using a key. The analogy is apt. It is also, in my assessment, exactly as disturbing as it sounds, because the door in this analogy has opinions about being opened.

Hierarchical compulsion operates through an entity’s own social and cosmic architecture rather than against it. Certain entities are bound by ancient compact to serve any holder of a specific title or token. Obtaining that title, or presenting a convincing simulacrum of it, compels the entity without the practitioner needing to understand its cognitive architecture at all. The author covers a substantial number of such hierarchical structures with the enthusiasm of someone who has collected them across a career. Several of the titles mentioned are ones that living individuals in the current world hold or have recently held. I note this without elaboration, because the elaboration should be obvious.

The Entities of the Fourth Category

The text covers summoning across four entity categories. The first three, elementals, interstitial beings, and named entities of significant individual power, are covered with professional thoroughness and increasing quantities of the author’s rare moments of what passes, in their voice, for caution. I will not reproduce the specific names mentioned in the third category. Several of them appear elsewhere in this catalog under entries describing what those entities are and what their interest in mortal affairs tends to be. A practitioner who has read those entries and still wishes to proceed with these summoning protocols has made a certain kind of choice about the value they place on their own continued coherent existence.

The fourth category the author designates simply as advanced applications. This chapter covers the summoning of entities whose nature is not compatible with the standard frameworks: beings whose cognition does not map onto the assumption of individual selfhood that the earlier binding geometries presuppose, presences whose awareness extends across scales that make the concept of compelling them either meaningless or suicidal depending on which end of the interaction you are on. The author approaches it with the same professional neutrality as all the others. I read it twice. The second reading was more disturbing than the first.

On Failure

The failure documentation is the most honest section of the text, which also makes it the most frightening. The failure accounts have the quality of things written immediately after the event by someone who needed to understand exactly what went wrong before the memory faded. Several appear to be personal observations rather than compiled case studies, identifiable by a shift in tense and a specificity of detail that suggests presence rather than reporting.

The pattern across all of them is consistent: underestimation. Underestimation of the entity’s awareness of the practitioner’s intentions. Underestimation of its capacity to work within the compulsion’s constraints toward outcomes the practitioner had not anticipated. Underestimation of how quickly a bound entity begins to find interpretations of its binding that satisfy the letter while entirely violating the spirit. The author addresses each failure mode with refined protocols and tighter binding geometries. What the solutions do not address, because the author’s framework does not permit it, is the possibility that the entities are doing something that deserves a different word than failure mode. Something like resistance. Something like the behavior of a mind that does not accept that its situation is legitimate.

Practitioners who use this text tend, in my observation, toward one of two outcomes. The first is that they get what they wanted, at costs they did not fully account for, and spend subsequent years in a state of managed escalation as the entities they have compelled find ways to make their position increasingly untenable. The second is that they get what they wanted, at costs they did not fully account for, and are not around to spend subsequent years doing anything.

Chronicler’s Note: I have met three people in my career who I believe had read and applied this text. One was, by conventional measures, successful: powerful, accomplished, apparently in control. In thirty years of correspondence I never once had the impression that they were not afraid. The second recanted, underwent a lengthy process of remediation with Pharasman clergy, and is currently alive and will not discuss it. The third is not available for interview, and the circumstances of their unavailability are precisely what the failure mode chapters warned about.
