They are called the Ceramic Men, which is a misnomer on two counts: they are not ceramic in any material science sense, and they are not men. They are sexless, and whatever they are made of is something that resists precise analysis — smooth, white, warm to the touch at approximately body temperature, and structurally unlike any known inorganic compound. The name stuck because it is what they look like. Somebody said it once, a hundred years ago or last week, and now it is the only word anyone has.

Physically they are not imposing. They stand at roughly three-quarters the height of an adult human, their proportions orthodox — two legs, two arms, a torso, a head — arranged in dimensions that are close to human without being quite human in the ratios. The scale is off by enough that being near one feels slightly like looking at a photograph that has been subtly wrong-printed. Their surface is smooth, uniformly white, and all but featureless, as if each one was produced from the same mold and released into the world with the same face, the same hands, the same everything. In a crowd of humans, a Ceramic Man does not disappear. It does not blend. It simply stands there, shorter than everyone, utterly itself.

The face is a mask. This is the common description and it is accurate: a white oval with the suggestion of features — two slight depressions where eyes might be, a narrow ridge where a nose might be, a horizontal seam where a mouth might be. Nothing articulates. They do not smile. They do not frown. Whatever they communicate emotionally, if anything, they communicate through posture, through timing, through the selection and arrangement of words. Their face does not help you. Many people find this unnerving. The Ceramic Men have observed this and appear indifferent to it.

They are chipped. Every individual has them — chips and cracks in the white surface that have been collected over time from impacts, near-misses, the accumulated small catastrophes of an existence in a world built for softer or harder things than whatever they are. No two have the same pattern. This is, in practice, the only way to tell them apart. The chips are their biography, worn on the outside.

The face is never punctured. This fact is understood by anyone who has spent time around them, communicated in the way important things are communicated in the GLMZ — through the behavior of the people who know. Nobody presses on a Ceramic Man's face. Nobody points anything at a Ceramic Man's face. Their essence — whatever animates them, whatever produces the cognition and the patience and the careful words — is understood to be gaseous in nature, held under some pressure inside the structure of the skull. Puncture the mask and it escapes and they die. This is not a theory. It has happened. The event was not large. A Ceramic Man simply stopped. The thing inside the mask dispersed, whatever it was, and what remained was a white figure sitting in a chair that would never move again.

They are brittle by the nature of what they are. They break. They crack. They are not built for violence and they know it and they have, over however long they have existed, become absolute authorities in the avoidance of situations where violence becomes possible. They negotiate. They mediate. They broker. They stand between parties who want to destroy each other and they find the arrangement that makes destruction less attractive than the alternative. They are good at this because they have done it for a very long time and because they cannot afford to be bad at it.

How long is a very long time? No one knows. The oldest documentation of a Ceramic Man in GLMZ is approximately 80 years old, a ledger entry from a pre-incorporation notary describing 'the small white figure who witnessed the signing.' Whether it is the same individual present today is not confirmable. No Ceramic Man has died of natural causes in any documented period. Their components do not appear to decompose at an observable rate. They do not eat. They do not sleep, as far as anyone has been able to determine. They are simply present, in the locations where they have established themselves, doing what they do.

Where they come from, they do not say. Whether this is because they are protecting something or because there is genuinely nothing to say — whether they were made, or grew, or arrived, or have simply always been here in the specific way that certain things simply have always been here — is not known. The question has been asked. They have been asked directly, by people with leverage and people without, by people who wanted to know and people who wanted to profit from knowing. The answer is always some variation of the same thing, delivered in the same pleasant, affectless tone: they do not think that information would be useful in the context of the present conversation.

They have basic emotional responses. This is the characterization that emerges consistently from the accounts of people who have dealt with them over time — not that they have no feelings, but that the feelings they have are simple and do not compound. They prefer certain outcomes to others. They dislike certain situations. They appear to have something that functions as satisfaction when a negotiation concludes well. They do not appear to have grief, or longing, or boredom, or spite. Whether they are incapable of these things or have simply decided not to have them is, like most questions about the Ceramic Men, not answerable from the outside.

What they have, consistently, across every documented account, is patience. They will wait. They have been waiting, in their quiet way, for whatever it is they are waiting for, and in the meantime they are available to help you and the person who wants to kill you find an arrangement you can both live with. Their fee for this service is information. Not money. Not favors. They want to know things. Every time they help you, they ask one question, and they listen to the answer with their entire attention, and they remember it, and they never tell you what they do with it.
