Modrons are beings of absolute law that adhere to a hive-like hierarchy. They inhabit the plane of Mechanus and tend its eternally revolving gears, their existence a clockwork routine of perfect order.
Absolute Law and Order. Under the direction of their leader, Primus, modrons increase order in the multiverse in accordance with laws beyond the comprehension of mortal minds. Their own minds are networked in a hierarchal pyramid, in which each modron receives commands from superiors and delegates orders to underlings. A modron carries out commands with total obedience, utmost efficiency, and an absence of morality or ego.
Modrons have no sense of self beyond what is necessary to fulfill their duties. They exist as a unified collective, divided by ranks, yet they always refer to themselves collectively. To a modron, there is no “I,” but only “we” or “us.”
Absolute Hierarchy. Modrons communicate only with their own rank and the ranks immediately above and below them. Modrons more than one rank away are either too advanced or too simple to understand.
Cogs of the Great Machine. If a modron is destroyed, its remains disintegrate. A replacement from the next lowest rank then transforms in a flash of light, gaining the physical form of its new rank. The promoted modron is replaced by one of its underlings in the same manner, all the way to the lowest levels of the hierarchy. There, a new modron is created by Primus, with a steady stream of monodrones leaving the Great Modron Cathedral on Mechanus as a result.
Rogue Modrons. A modron unit sometimes becomes defective, either through natural decay or exposure to chaotic forces. Rogue modrons don’t act in accordance with Primus’s wishes and directives, breaking laws, disobeying orders, and even engaging in violence. Other modrons hunt down such rogues.
A rogue modron loses the Axiomatic Mind trait and can have any alignment other than lawful neutral. Otherwise, it has the same statistics as a regular modron of its rank.
The Great Modron March. When the gears of Mechanus complete seventeen cycles once every 289 years, Primus sends a vast army of modrons across the Outer Planes, ostensibly on a reconnaissance mission. The march is long and dangerous, and only a small number of modrons returns to Mechanus.

What's a mortal to make of the modrons, those strange creatures of absolute order who whir and click on the plane of Mechanus? Theirs are not like other lives - even the infinitely subtle baatezu are more comprehensible than these thronging drones. To an outsider it appears the modrons have no existence other than as a whole. Indeed, there is a saying: "To look at one modron is to look at all of them."
It is only logical, as it is with all things modron, that they are native to the orderly plane of Mechanus. The two, plane and modrons, probably would not exist without each other — modron society defines the plane, just as the plane shapes them. To understand the modrons, a being must stop thinking like a person, like an individual. Only then can anyone hope to comprehend the patterns of modron life.
Modrons are strictly divided into fourteen castes. Castes are hardly unique, but the modron approach to them is. Not only does each rank have its own functions, but each also has its own body shape, so the rank of any modron can be readily identified by the creature's appearance.
Ruling over the castes is Primus, the One and the Prime. It and the plane are one in thought and deed; as Primus turns, so do the wheels of Mechanus.
Combat: Regardless of rank, all modrons possess certain abilities and immunities, but because of rank, certain modrons - the hierarchs — possess additional abilities. Whether any of these immunities and powers exist as properties of their race or from association with the plane of Mechanus, no one knows. Most scholars think these powers are natural to the race, as none are lost by modrons operating off the plane of Mechanus.
All modrons are unaffected by any illusions or magic that affects the mind, such as beguikment, charm, domination, hold, hypnosis, and sleep. Fear and other emotion spells are similarly ineffective against a modron, as are attacks drawing upon the Positive and Negative Energy Planes (including life-draining powers). All modrons save vs. cold, fire, and acid attacks with a +1 bonus, and they suffer damage from such attacks with a -1 modifier per die.
Modron hierarchs are never surprised, and their precision of order always allows them to determine their specific place in the initiative sequence of all attack rounds. Thus, they never roll for initiative, and the DM chooses when they will act. Typically, this comes at the most effective moment, just before the swordsman's blade arcs through the air or the wizard utters the final word of a spell, and so on. The elite modrons also can perform the following spell-like abilities, once per round, at will: clairaudience, clairvoyance, command, dimension door, teleport without error, and wall of force. They also are capable of traveling on the Astral and Ethereal Planes, but will never do so unless ordered by Primus.
All hierarchs can communicate telepathically, and the range of this power is as follows:
Rank:
Decaton = 44 miles
Nonaton = 63 miles
Octon = 80 miles
Septon = 190 miles
Hexton = 216 miles
Quinton = 238 miles
Quarton = 384 miles
Tertian = 405 miles
Secundi = 420 miles
Primus = All Mechanus
Habitat/Society: To understand modron society, one must abandon all understanding of the self. In such forgetting comes knowledge, so with the surrender victory is gained. Should the scholar retain the slightest glimmer of who he is, his words are tainted and his observations lies. It is said that those able to strip their souls so bare become modrons, themselves, and their spirits become different from their shells.
It is a fundamental property of the modrons that each rank can only comprehend the existence of the rank directly above and below it. For example, the monodrones obey the will of the duodrones, but they cannot even conceive of the existence of the tridrones. When a monodrone sees a tridrone, it does not see a modron, and it could not even say what it sees. Some aphasia apparently breaks the link between the sight of the higher modron and what it actually is. This blindness leads to an interesting conclusion, as each rank believes that those immediately above it are the highest form of life and the fountainhead of supreme logic. Thus, Primus's lordship is secret from all modrons but the four secundi, who pass his edicts on to the nine tertians, who in turn pass these to the quartons (who have no knowledge or understanding of either the secundi or Primus), and so on.
There is an awareness of all ranks below a modron's station, yet communication is exclusively limited to adjacent ranks. It would seem that the monodrone is almost as alien to the tridrone as the tridrone is to the monodrone. This is not the result of elitism. Rather, the strict order observed by the race completely negates the slightest necessity for communication beyond immediate inferiors and superiors.
A modron's perception of its immediate superiors should not be mistaken for deification, either. What others might call a god, the modrons cannot imagine, for they are unable to conceive of such an individual existence. Instead, all life and direction spring from a pool of logical action - all that is right happens because it must inescapably be, and all that is wrong is that which must not be. These metal limitations make dealings with modrons a challenge. Within each rank there is no individuality, either in form or thought. All modrons call themselves "we," and a character has no way of knowing if the pentadrone he spoke to today is the same as the one who held the same post yesterday. This would be minor if the modrons weren't so bureaucratically driven, requiring strangers to appear and reappear before clerks, courts, and boards. Some travelers solve the problem with a brush and paint, marking modrons with runes simply to tell them apart. Unless instructed to remove these marks, a modron may wear a splash of color or a strange sigil for the rest of its life, for they don't seem to notice the markings themselves.
Even the size of modron society is rigidly fixed. In each rank there are only a set number of modrons. Should a modron of any rank die, an available candidate from the next lowest rank is promoted, and then the gap in the lower rank is filled by promoting from the still lower rank. This continues until the rank of monodrone is reached. With no lower ranks, the creatures at this level reproduce by fission, as one of their members mysteriously divides into two. (Given this, the claim that all modrons are one might be truer than it first seems.)
Promotion occurs seemingly by accident. As soon as a vacancy occurs, the nearest modron of the next lowest rank is recruited to ascend. Since they have no individuality, there's no point in trying to promote the "best and the brightest"; all modrons of a given rank are deemed equal. Promotion is traumatic — not only does the chosen modron undergo a wrenching change of shape to the new rank's form, but it suddenly gains an understanding of a world previously veiled to it: the existence of a yet superior rank. Imagine the shock of a duodrone, who knew only of monodrones, duodrones, and tridrones, when it suddenly discovers those inexplicable creatures around it are quadrones and members of its own race! On the other hand, the newly promoted modron seems to adapt to its new form instantly, and it is the humanoid observer who is often most shaken by the experience.
From greatest to least, the castes of the modrons are listed below. Numbers are not given for the modrons, since no scholar has yet produced the definitive organization chart of these creatures. After each name is a brief description of that rank's duties in their realm of Mechanus.
Primus: Absolute ruler of all modrons
Hierarch Modrons
Secundi: Viceroys of the four quarters
Tertians: Judges
Quartons: Rulers of the four regions of the four quarters
Quintons: Bureau chiefs and records keepers
Hextons: Generals of the armies of modrons
Septons: Inspectors
Octons: Governors of the four sectors of the four regions of the four quarters
Nonatons: Police supervision
Decatons: Physical welfare of base modrons
Base Modrons
Pentadrones: Lesser police, law enforcement
Quadrones: Multiple complex tasks, supervision
Tridrones: Multiple tasks, minor supervision
Duodrones: Complex tasks
Monodrones: General laborers
The realm of the modrons occupies 64 of Mechanus's coglike wheels, called sectors, and each is governed by an octon. The sectors in turn are grouped into foursector regions, overseen by the 16 quartons, and each group of four regions, called quarters, is supervised by one of the four secundi. And, of course, all of it is ruled by Primus.
Born through parthenogenesis, modrons have no family, tribe, or clan. Instead they live in rigid numerical units called, for lack of a better word, battalions. This makes them sound more warlike than they really are, although modrons have standing armies that are not to be trifled with.
Although some less-informed scholars state that no modron acts except by the orders of a superior, this is not perfectly accurate. In general, a modron can act and react to a situation on its own, provided the situation falls within the range of its purpose. Thus, monodrones, who can only fulfill a single task at any given time, are rightly seen as incapable of reacting. As one moves higher through the ranks, the range of choices and reactions available to any given modron increases. Even so, modrons are notorious for their predictable and rigid reactions to events.
It should be no surprise that the goal and purpose of every modron is to organize Mechanus in the most orderly fashion possible, but their goal is not limited to only their 64 wheels or even Mechanus itself. Given the opportunity, they would spread their rigid pattern of organization over the entire multiverse. Fortunately for the rest of the planes, order is constantly challenged by chaos, even in the clockwork vastness of Mechanus. Since even the slightest imperfection to order is enough to disturb the harmony modrons seek, they seldom find the time or resources to carry their crusade to other realms or planes.
Modrons speak their own precise, mathematical language, but those of duodrone or greater can manage at least some of the trade tongue found throughout the planes.
Modrons fulfill many roles within Mechanus. They maintain parts of the sphere and are maintained by it. They make war with their enemies and trade with their neighbors. Together, they are one living social entity. Those few that venture outside their plane (on orders from their superiors) will always attempt to bring order out of chaos, sense out of nonsense.
Modrons are not completely without their uses to the rest of the multiverse. Their single-minded pursuit of order has a certain usefulness in some fields. On rare occasions, nonmodrons can hire members of this race for particular tasks. The process is never simple, since the potential employee can never make the decision itself - all requests must be approved by its superiors. Usually the request has to pass through several ranks before an answer is given.
If permission is granted, some wizards find modrons to be amazingly useful as librarians, and merchants may retain them as bookkeepers, although such modrons must always be watched for overzealousness. Sometimes their understanding of order, far deeper than that of most other beings, defies human understanding. In one library, all the books might be arranged by subject, in another by the first letter of the first word, and in yet a third by the page where the last diagram appears. All three might be vital keys in the overall order of the modron universe. Order, after all, does not necessarily need to be understandable.
The bodies of modrons slain anywhere immediately disintegrate. It is suspected that whatever energies were trapped within the creature's mortal form find their way back to Mechanus and merge with the energy field of the plane. This field is what sustains the modron race. Although modrons eat physical food, it is not the substance that sustains them, but the energy essence contained therein. So long as the modrons are able to draw upon this essence, they can continue to split and perpetuate their kind. In fact, it is speculated that the only means to truly crush this race is to cut it off from this energy pool. Given the impossibility of this feat, it is fortunate that modrons are not a particularly aggressive race. Who, after all, could withstand a single-minded army that constantly regenerated itself?
PRIMUS (THE ONE AND THE PRIME): Primus is the ruler of all the modron realm. It and it alone understands the whole structure of the modron race, since it sits at its pinnacle. From there it decrees what is order, writes the laws, and establishes the rules and regulations. All other modrons exist to carry out the plans and obey the rules of Primus. Failure to meet this powerful creature's standards will result in a modron being declared rogue and sentenced accordingly.
Primus is a huge being who rises from an energy pool in the central part of its great tower at the center of the plane (although Primus also may appear as a normal androgynous human). In giant form Primus's hands are unseen, for the right one is swathed in bright rainbow hues and the left is covered with inky dark clouds.
Within Mechanus, Primus has the status of a greater power, except it is possible for Primus to die, albeit only under near-impossible conditions. Its sole concern is for the modrons. It does not send avatars to other planes or even take part in the normal bickering and wars of the planar powers. All modrons with priestly powers gain their spells directly from it.
The death of Primus does not break the link in modron society, for like all gaps, the vacancy is filled by promotion of the one of the secundi. However, the process usually creates turmoil since, without a Primus, chaos is allowed to enter into the perfection of modron society. Some scholars have mistakenly interpreted this chaos as civil war within this orderly race. The first act of the new Primus is to return order to its race, a process which can take some time.
Rogue Units:
Even in the perfect modron world there is disorder, and sometimes this disorder strikes at the very fabric of the modron society. When this happens, a modron may go rogue. This is most common in the base modrons, although there are cases of a few hierarchs being affected this way (but certainly never any hierarch of quarton status or higher!). Rogue modrons do not act in accordance with Primus's wishes and directives, but break laws, disobey orders, and sometime become violent. These rogues are hunted down, usually by the pentadrones under the command of the nonatons.
Once captured, the rogue is tried and sentenced according to the laws of Primus. For a lowly base modron, this is a bewildering series of events, as strange beings (hierarch modrons) describe the crimes committed and the punishment that is due. It can only seem like the judgment of angels upon a hapless mortal, and many sages would dearly love to know just what modron theology makes of the whole thing.
The Armies of the Modrons:
There are 36 great armies in the realm of the modrons, each a powerful fighting force. Each of the 16 regions of the plane has its own army, and the secundi have two armies each, in addition to their regional forces. The tertians have three to aid in law enforcement and punishment. The final nine armies are stationed outside of Primus's tower and serve as a reserve force, should they be needed.
Each army is commanded by a hexton and is comprised of four corps. Each corps is led by 40 pentadrones in a telepathic hook-up with the hexton general. Each corps has two divisions commanded by 20 pentadrones, and each division has four brigades led by 10 pentadrones. Each brigade has four regiments, each one being the standard tactical unit, led by five pentadrones. There are 70 officers, 192 NCOs, 252 messengers, and 2,628 line troops in a brigade, for a total of 3,142.
A regiment consists of two "battles" plus a squad of winged monodrone messengers and a special squad of 12 pentadrones. Each battle is led by four quadrones and consists of six companies of monodrones, two companies of duodrones, a special company of tridrones, a squad of quadrones, and another squad of messengers. The eight regular companies are each divided into two wings plus a headquarters unit. Each company consists of 12 squads and three officers. A squad numbers 12 troops and will contain an NCO of the same type as the troops. Special units of messengers, "shock troops," and the like may be attached to the headquarters' units of brigades, divisions, and corps.
