Quadrones are the modron equivalent of field officers and skilled laborers. As troop leaders, they are the main point of contact in negotiations with other races, and because of their relatively high intelligence, rogue quadrones are more likely to escape Regulus than rogues of lower castes. As a result, other races deal with quadrones far more often than with other castes, and quadrones are seen by many outsiders as the archetypal modrons.
Quadrones are unflinchingly organized and capable of a high degree of planning and strategy. They prefer to begin combat with ranged attacks and close for melee only when their opponents come to them. They are well aware of lower castes' capabilities and order them to attack according to their strengths, and as the negotiators of the modron race, they are also usually knowledgeable of enemy races' weaknesses. They are ruthless and coldly unemotional in battle.
There are always exactly one-million five-hundred-thousand quadrones in existence at a time. A quadrone resembles a metallic cube with two spindly legs, four arms, and two fleshy faces at the front and back. Exactly one-fourth of all quadrones possess fan-like wings instead of a second pair of arms and act as scouts and aerial assailants.

Tridrones are low-level supervisors capable of limited resource management and decision making. Their spiderlike climbing ability and all-around vision, as well as their ability to report actions and observations, make them excellent scouts and guards. In the modron armies, tridrones are the equivalent of non-comissioned officers, supervising small companies of duodrones that in turn control a detachment of monodrones.
Tridrones are strange creatures of flesh and metal that resemble upside-down three-sided pyramids with a single eye, mouth, and arm on three of its four sides. Six spindly clockwork legs radiate from the bottom of its body. They are the lowest-ranking modrons capable of speaking the Common tongue, but they are rarely very talkative. There are precisely six million tridrones in creation at a given time.
In combat, tridrones are highly mobile, darting rapidly from one opponent to the next. Because they are used to working alone as scouts or border guards, tridrones are more likely to split up and fight as individuals than lower-ranking modrons. They take advantage of the terrain, preferring to climb walls to throw their javelins then drop down on their opponents.

Duodrones supervise monodrones and perform labor that requires moderate decision-making ability. Duodrones possess only dim intelligence by human standards, but they are capable of performing slightly more complex tasks than monodrones and employ limited strategy in work and combat.
Duodrones appear as a pair of small, flat rectangular flesh-and-metal boxes stacked on top of each other with spindly arms and legs. There are exactly fifty-five million duodrones in existence at any time.
Though not much taller than a gnome, duodrones are surprisingly strong for their size. They are used as heavy labor or shock troops. In combat, duodrones coordinate their attacks with each other, but are more likely than monodrones to split up to weaken individual opponents. They typically use their surge of strength in the first round of combat in an attempt to appear stronger than they actually are, hoping to scare off opponents without incurring heavy losses.

Monodrones are the lowliest and most basic of all modrons, the caste from which all others advance. At any given time, there are exactly three-hundred million monodrones in existence; they outnumber all other modrons combined.
Appearing as a metal ball with a single eye and spindly arms and legs, monodrones are capable of performing only a single task at a time, which they perform without question until ordered to stop. When ordered to fight, they focus on a single enemy until it is defeated, then move on to the next, eventually fighting each other if not ordered to desist. If ordered to guard, they stand watch without moving or blinking. If ordered to build, they continue building higher and higher without stopping.
Monodrones are the rank and file of the modron armies, swarming over opponents without mercy. The vast majority of monodrones serve as general labor, however, performing construction, repairs, transportation, and other menial tasks without complaint.

Fixed Initiative (Ex): A monodrone never rolls initiative. Its initiative is always equal to half its Hit Dice plus its Dexterity (2 for a typical monodrone).
Focused Strike (Ex): Once per day, a monodrone can take an additional standard action in a round. This action must be identical to the one it just performed. For example, a monodrone could make two melee attacks against the same target. It could not, however, move, make an attack, and then move again (as the moves do not immediately follow one another).
Single Task (Ex): Monodrones are only able to focus on a single task at a time. This tightened focus in combat translates to only being able to engage a single opponent in combat. Once it attacks a creature, the monodrone continues fighting the same creature until destroyed, its opponent is defeated, or it is ordered to attack another target. A monodrone cannot attack any other creatures except for its target, even if they provoke attacks of opportunity.
MESSENGER MONODRONE
Exactly one-third of all monodrones (one million, to be precise) have no arms, and instead possess fan-like wings that allow them to fly. These flying monodrones act as messengers.
Because hierarch modrons can all telepathically communicate with their wards, messenger monodrones are actually more common outside of Regulus than within it. Their flapping forms whirr constantly through the tunnel between Regulus and Axis, and they are a constant sight in the skies over the city-plane.
Messenger monodrone may be summoned as familiars by mages. Primus presumably allows this as a means of easily gathering knowledge from the Material Plane. Monodrone familiars follow their masters' orders without question, but their inability to perform more than a single task at a time can be frustrating for mortals.
Messenger monodrones have the same stats as common monodrones except as follows:
Speed: 20 ft., fly 40 ft. (average)
Melee: Bite +4 (1d4)
SQ: Coordinated ally, recite message
Recite Message (Ex): Messenger monodrones can be dictated a message in any language up to 1 minute in length. They then carry that message until a superior either dictates a new one or orders the current message forgotten. Monodrones do not understand messages not in the Modron language but can still recite them exactly, regardless of language. Monodrones cannot be used to cast spells in this manner, even those with only verbal components.
MESSENGER MONODRONE FAMILIARS
A spellcaster of at least 7th level with the Improved Familiar feat and whose alignment is within one step of lawful neutral can gain a messenger monodrone as a familiar. A monodrone is never promoted to a higher caste as long as it serves as a familiar.
Alien, dispassionate, inscrutable: such are the modrons, embodiments of order and law. These bizarre half-metal creatures exist for one purpose: to study and catalog the whole of existence, forcing chaos into order to fit their worldview. Hailing from the clockwork demiplane of Regulus, the modrons have no concept of the individual, each modron but a single cog in a great machine.
The modrons are strictly divided into fourteen castes that determine their form, function, and abilities. Each caste has a distinct appearance, and each member of a given caste is indistinguishable from all others. The five lowermost castes, the "base" modrons, are the workers, soldiers, guards, and police of their race, performing all menial tasks that keep Regulus running. The nine higher castes, the "hierarch" modrons, are the overseers, governors, inspectors, and judges, tasked with keeping Regulus running like a well-oiled machine.
At the pinnacle of the modron caste system is Primus, the One and the Prime, the sole individual mind in the modron collective; this godlike being is the modron race; all other modrons are as cells in Primus's vast, discorporate body.
Modrons do not reproduce as mortal beings do. There is a fixed number of modrons of each caste; when a modron of a given caste dies, its body crumbles to nothing, and a modron of the next lowest rank is instantly transformed into a member of the dead modron's caste. Another modron from the next rank below that is "promoted" to fill the gap, and so on down the pyramid until a new monodrone emerges from the energy pool at the heart of Regulus. The promoted modrons lose all memory of their previous existence, immediately knowing their new function in modron society.
Each modron is cognizant only of modrons of the rank directly above them and those below them. For instance, a tridrone recognizes only the lower duodrones and monodrones and the higher quadrones, and the existence of Primus is known only to the four secundi. They can acknowledge the presence of higher modrons, but cannot conceive of such inscrutable beings as members of their race. This presents no challenge to the flow of orders or information, however, as modrons follow the directives of their superiors without question, so orders descend from the highest to the lowest castes as easily as water trickling down steps.
THE GREAT MODRON MARCH
Every seventeen years (the amount of time it takes for the largest gear in Regulus to make a full rotation), millions of modrons boil forth from Regulus in a vast river of flesh and metal known as the Great Modron March. The march begins with a spiral route around Axis before embarking on a tour of every plane of existence, from the Outer Sphere, through the Astral, to the Elemental Planes, the Material Plane and its mirrors, the Shadow and Ethereal Planes, before finally returning the way it came back to Regulus.
The purpose of the Great Modron March is not entirely clear, but it appears to be a knowledge-gathering mission to observe each of the planes in their turn. The modrons leave a swath of destruction in their wake as they mindlessly stomp out chaos and try to force the local landcape into perfect ordered systems. Countless modrons die on the march, their essences returning to Regulus to form fresh monodrones. The Great Modron March is both a threat and a spectacle, viewed by inhabitants of the planes as half invasion, half parade.
ROGUE AND EXILED MODRONS
Every so often, orders are misinterpreted, contradictory orders reach a single modron from two different chains of command, or a modron simply becomes aware of its own individuality. Such modrons become rogues, and most go mad and rampage. Rogue modrons are ruthlessly hunted down and destroyed, but a few escape to other planes and wreak havoc. Most rogue modrons are base modrons, and pose little threat to the order of Regulus, but on very rare occasions a hierarch goes rogue. When this happens, it can spread its dissenting voice among all lesser modrons under its command, spreading chaos like a disease until it is put down by its former superiors.
Some rogue modrons become aware of their newfound individuality early on, however, and systems are in place that allow them to petition peacefully for exile from the modron collective. Exiled modrons are physically transformed and cut loose from Regulus, free to explore the planes on their own initiative.
MODRON TRAITS
Modrons are a race of lawful neutral outsiders that hail from the clockwork demiplane of Regulus. A modron possesses the following traits (unless otherwise noted in a creature’s entry).
Resistance to acid 10, cold 10, and fire 10.
All base modrons speak Modron. All hierarch modrons speak Celestial, Common, Modron, and Infernal.
A modron's natural weapons, as well as any weapons it wields, are treated as lawful for the purpose of resolving damage reduction.
Constructed (Ex): Although modrons are living outsiders, their bodies are constructed of physical components, and in many ways they function as constructs. For the purposes of effects targeting creatures by type (such as a ranger's favored enemy and bane weapons), modrons count as both outsiders and constructs. They are immune to disease, mind-affecting effects, paralysis, poison, and sleep. Modrons are not subject to fatigue, exhaustion, or energy drain.
Coordinated Ally (Ex): Modrons work exceptionally well with other lawful allies. When successfully aided on a skill check or attack roll by a lawfully-aligned ally, or when aiding another lawfully aligned creature, they apply or gain a +3 bonus on their checks or attack rolls (instead of the normal +2 bonus). Furthermore, modrons gain a +4 bonus on attack rolls against an opponent flanked by a lawfully-aligned ally (instead of the normal +2 bonus).
Fixed Initiative (Ex): Modrons are rigid in their action, even in the most chaotic situations. As a result, a modron's initiative check is always equal to half its Hit Dice plus its Dexterity modifier or other modifiers (like Improved Initiative). When combat begins, a modron uses this number as its initiative - it never rolls an initiative check.
Skills: All modrons have a +2 racial bonus on Perception checks.
REGULUS
The home of the modrons, Regulus is a demiplane that exists metaphysically inside the city-plane of Axis. Accessible through a great tunnel near the center of Axis, travelers to Regulus emerge near the heart of the demiplane outside the great Modron Cathedral, the dwelling of Primus.
Regulus takes up a finite, but incredibly vast, area. The demiplane consists of sixty-four nation-sized gears with modron structures erected on both surfaces. Each gear is ruled by an octon administrator; four gears make up each of the demiplane's sixteen sectors, each ruled by a quarton governor; and four sectors are grouped into one of the plane's four quarters, each ruled by a secundus viceroy. At the center of Regulus is the Modron Cathedral, where Primus rises from the great Energy Pool.
Although modrons are the dominant race of Regulus, they are not the only inhabitants. Axiomites and inevitables come and go freely from Axis to Regulus, and indeed the creation of the inevitables is said to have been inspired by the machinelike modrons. Formians from Axis sometimes tunnel down and attempt to colonize the demiplane, but so far the modrons have kept them in check. Humans and other mortals, archons, devils, and other planar travelers also occasionally come to Regulus seeking knowledge, though the modrons' infuriatingly bureaucratic nature makes such pursuits frustrating to say the least.
REGULUS PLANAR TRAITS
Finite Shape
Divinely Morphic: Primus can alter the plane at will.
Strongly Law-Aligned
Enhanced Magic: Spells and spell-like abilities with the lawful descriptor are enhanced.
Impeded Magic: Spells and spell-like abilities with the chaotic descriptor are impeded.
Objective Directional Gravity: The direction of "down" is oriented to the face of each rotating cog. Walking between cogs can be dizzying for newcomers - and dangerous if a traveler falls between the cogs.
Every city needs maintenance workers, and the Eternal City of Axis is no exception. In this multiversal hub of law and trade, the tasks of building, wrecking, sanitation, public safety, and every other conceivable job is filled by the enigmatic dabus.
No one is quite sure where the dabus (the name is both singular and plural) came from. The axiomites did not create them like the inevitables or the justicators, nor were they created by a deity like the Axial avengers, nor did they migrate to the city like the formians or visilights. They simply appeared long ago, fading into existence one by one with an instinctual drive to work, and seeing no reason to stop them, the axiomites simply let them do so. Some sages speculate that the plane of Axis itself unconsciously birthed them from its own fabric, but for their part the dabus neither know nor care.
There are millions of dabus in the city who work constantly to keep the city running. Though they are sentient and free willed, dabus do not seem to have any wants or needs besides the maintenance of Axis. When an individual dabus is done with its day's work, it merely disappears before reappearing the next day; no one knows where the dabus go during this time. Dabus are brusque and callous, and give only a perfunctory warning to nearby creatures before they get to work. When the task to which they have set themselves is demolishing an inhabited building, this can be a problem. Axis natives have learned to live with the dabus, but outsiders often see them as an incredible nuisance.
DABUS REBUS TALK
The most bizarre aspect of dabus is their mode of communication: rebus talk. Rebus talk may be frustrating to employ in-game; here are some suggestions for how to handle it.
1. Let the Dice Decide: When PCs encounter a dabus who speaks to them, you can require each PC to make an Intelligence or Linguistics check to understand its speech symbols. A DC 10 check allows a PC to understand simple words and short phrases. A DC 15 check allows translation of short sentences about common topics (such as money or directions). A DC 20 check is required to understand a complete conversation about past, present, or future events, and DC 25 check is needed for complex, abstract discussions about topics such as strategy, magic, politics, philosophy, or religion. Add 5 to each of these DCs if either the party or the dabus is under time pressure to communicate quickly.
This method is easy to resolve, but it takes much of the mystery out of the dabus.
2. Nonverbal Substitutes: When a dabus encounter occurs, you can substitute some other nonverbal form of communication - such as pantomime - to simulate the strangeness of the dabus and their speech. Simply state that the dabus spews a torrent of incomprehensible symbols, then it resorts to pantomime to make itself understood.
3. Rebuses: The method that most actively portrays the mystery surrounding the dabus requires a bit of advance preparation. You can draw up two or three rebuses for a dabus encounter for the players to decipher. Imagine the players' surprise when the PCs ask a question and you hold up one or more rebuses as a reply!
4. Translator: In all cases, rebuses or pantomime should be used for fun, not to bog down play. If the characters need to know something in a hurry, or your game time is short, an NPC native to Axis can offer to "translate" what the dabus says for the party without making any die rolls.
Axial avengers are a race of beings tasked with patrolling the Hinterlands of the Eternal City of Axis, the greatest bastion of order in the multiverse. They were created mere centuries ago by Aroden, the god of humanity, with the cooperation of the plane's native axiomites to defend the perimeter of Axis and strike back against the invading proteans and demons. With the loss of Aroden one hundred years ago, the avengers' name has taken on a new meaning as they now seek relentlessly for the secret behind their creator's death.
Due to the axiomites' hand in their creation, Axial avengers possess only slightly more humanity than the automaton-like inevitables, viewing every situation as a complex set of variables and calculations to be weighed against each other. Despite their rigidity, they recognize the importance of peace and harmony and err on the side of good more often than evil. They have a mathematical outlook that makes them seem distant and alien to mortals. Axial avengers often serve as backup to more powerful inevitables and justicators, their analytical minds making them skilled tacticians. When not on patrol or in battle, Axial avengers live spartan lifestyles as they await further orders.
Because of their appearance, Axial avengers are often mistaken for the likewise metallic legion archons of Heaven. Those expecting an archon's mercy from an Axial avenger are in for a rude awakening.
