The current models of inevitable. * See canonwatch notes

The inevitables are a race of living constructs created by the axiomites, those beings of pure law who inhabit the Eternal City of Axis. Designed to enforce multiversal laws and combat chaos, the first inevitables were originally forged in the Adamantine Crucible of Axis and each imbued with a singular purpose tied to a specific law or principle, such as upholding contracts, ensuring the sanctity of death, or protecting planar boundaries. Their forms are humanoid but purely mechanical, often appearing as works of art made from metal, stone, and jewels. Despite their construct-like appearance, they are living outsiders who do not tire, hunger, or succumb to disease. Inevitables are in theory incorruptible, and usually relentless in their duties, operating across planes to correct violations of cosmic order.

While inevitables share some similarities with aeons and modrons as agents of law, they differ significantly in purpose and approach. Aeons are enigmatic beings created by the Monad to maintain balance across opposing forces (eg. life and death)—and they often work in abstract ways to restore multiversal equilibrium without rigid adherence to laws. Inevitables, by contrast, focus on enforcing specific laws or principles with precision and always by direct intervention.

Modrons, on the other hand, are constructs from Mechanus that embody absolute order and hierarchy. Inevitables operate independently and are more flexible in their methods, allowing for discretion in achieving their goals, which span planes and cultures. Unlike inevitables, modrons adhere to an extremely rigid chain of command and often act collectively rather than individually. They care little for the laws of the multiverse at large, being far more involved in maintaining the Great Machine of Mechanus.

To get the better of an inevitable, one must exploit its rigid programming and predictable behaviour. Though they are highly intelligent and adaptive within their mission parameters, inevitables lack creativity outside their primary purpose. Disguising actions as lawful or creating situations that fall into morally gray areas can confuse or delay them. Additionally, inevitables rely heavily on their physical resilience and spell-like abilities; countering these with unexpected magic-resistant defences or exploiting vulnerabilities specific to their construct-like nature (such as electricity or rust effects) can provide an edge in combat. However, defeating an inevitable is rarely a simple task—its creators can track its destruction and may dispatch another to continue its mission.

A Bestiary of Bylaws

Arbiter

Who monitor the encroachment of chaos

LN; CR 1 †

Arbiters are small, spherical inevitables adorned with gleaming metal wings, embodying the duality of observation and diplomacy within the aeon hierarchy. Serving as scouts and mediators, they traverse the multiverse to monitor the spread of chaos and guide lawful beings back to the path of order, often acting as intermediaries for the Convergence. Their philosophy emphasises persuasion over force, preferring to counsel and influence rather than command outright, though they are unyielding in their disdain for chaos. Arbiters are equipped with protective and commanding abilities, and they use their powers strategically to safeguard allies or disarm foes, reserving their energy bursts attacks for only the most critical battles in service to law. Despite their diminutive size—measuring just a foot in diameter—they carry significant weight both literally and metaphorically, often partnering with lawful spellcasters as familiars to further their mission of maintaining cosmic balance.

Novenarut

Who ensure the rules of duelling are upheld

LN; CR 4 †

The novenarut is a clockwork embodiment of martial discipline, resembling a samurai clad in intricate armour forged from jade and steel. Its humanoid form is adorned with whirring gears visible beneath its armour plates, and sports six green compound eyes—each composed of three lenses. Created by the axiomites to oversee and officiate duels, novenaruts ensure that high-stakes conflicts, are conducted with fairness and honour. They wield katanas with precision and can parry attacks with remarkable skill. For planewalkers encountering a novenarut, respect for its rules of engagement is paramount. These constructs are unyielding in their pursuit of honourable resolution and will not tolerate dishonourable acts, such as attacking helpless foes or employing underhanded tactics or dirty tricks. Be mindful that a novenarut’s ability to smite dishonourable foes makes it a formidable adversary for those who flout its strict code of conduct. If you must interact with one, approach with deference to its purpose to avoid triggering its wrath.

Keledon

Who protect the establishment from subversive art

LN; CR 5 ‡

Keledon, sometimes referred to as the “golden muse,” are dazzlingly artistic constructs. They appears as a humanoid figures of gleaming golden metal, often resembling angels with great feathered wings, a harp in one hand, and a rapier in the other. These inevitables are tasked with safeguarding the arts and crafts that uphold civilization’s order and stability. From music to shoemaking, no craft is too humble or grand for their attention. However, their devotion to preserving tradition can lead them to suppress works that challenge the status quo, such as revolutionary inventions or subversive art. Artists who stray into these realms may find themselves targeted by the keledon’s relentless efforts to discredit or destroy their work. While they can be generous patrons and allies to those whose creations align with their ideals, they are implacable foes to those who disrupt societal harmony through their craft. If you seek their favour, appeal to their appreciation for discipline and craftsmanship. However, if your work challenges authority or tradition, tread carefully—keledons are not easily swayed from their purpose. After a series of unfortunate recent incidents, the Society of Sensation has now barred keledon from entering the Civic Festhall.

Kastamut

Who defend traditions and cultures from unwelcome change

LN; CR 6 †

The kastamut is a stout, clockwork construct resembling a dwarf, crafted from an unusualy alloy of dark bronze or steel. Tasked with preserving the traditions and cultural heritage of civilisations across the Great Beyond, kastamuts ensure that societal customs arise and evolve without descending into chaos or being erased altogether. They possess the ability to discern a creature’s cultural background with a mere glance, allowing them to judge whether actions align with or threaten established traditions. While generally impartial, kastamuts can be relentless in their mission to maintain order within cultural evolution. Planewalkers encountering a kastamut should approach with respect for its dedication to cultural stability. These beings are not easily swayed by arguments of progress if they perceive such changes as reckless or harmful to local traditions. Cooperation is possible if your goals align with their mandate, but those who disrupt societal norms or traditions may find themselves facing the unyielding judgment of these mechanical guardians.

Zelekhut

Who pursue fugitives from justice

LN; CR 9

The zelekhut is a mechanical centaur-like construct, crafted from silvery metal with golden clockwork wings and arms ending in barbed chains that crackle with electricity. Tasked with enforcing justice, zelekhuts are relentless bounty hunters and executioners, pursuing fugitives who attempt to evade lawful punishment. They do not pass judgment themselves but instead uphold the laws of the societies they serve, no matter how varied or flawed those laws may be. They are exceptional trackers and captors, ensuring their quarry will have a hard time escaping them. Planewalkers facing a zelekhut should be aware of its single-minded focus and unyielding adherence to law. It will not harm innocents or act outside the bounds of its mission, but it is nearly impossible to dissuade or deceive. If you are aiding a fugitive or attempting to obstruct its pursuit, expect no mercy. Cooperation or negotiation is only possible if you can convince the being that your actions align with its lawful purpose. Mercykillers have been attempting to recruit zelekhut to join their faction recerly, so far unsuccessfully.

Impariut

Who ensure a society’s laws are administered fairly

LN; CR 10 †

The impariut is a stately inevitable dedicated to responsible governance and ensuring that laws are administered fairly. Standing precisely seven feet tall, it resembles a humanoid crafted from polished metal and wood, adorned in noble regalia such as a crown or a chain of office. Impariuts act as impartial diplomats, knowledgeable advisors, and intimidating judges, intervening when governments falter or rulers abuse their power. They are equally skilled at fostering cooperation through reasoned negotiation as they are at delivering punishment to those who undermine lawful governance. If you encounter an impariut, you should approach with respect for its mission of upholding justice and order. It is wise to present arguments logically and in alignment with the principles of fair governance, as these inevitables are immune to emotional manipulation or deception. Those who act in bad faith will find themselves swiftly opposed by the impariut’s formidable abilities, both diplomatic and martial. Cooperation is possible if your goals align with its mandate, but defiance will likely result in relentless pursuit and correction.

Valharut

Who are stalwart defenders from the forces of chaos

LN; CR 11 †

The valharut is a fearsome inevitable designed primarily as a soldier in the axiomites’ eternal war against chaos, particularly their nemeses the proteans and the encroachment of the Maelstrom. Valharut appear as four-armed, faceless female humanoids with pale marble-like skin veined with glowing blue lines. Unlike other inevitables that protect specific laws or principles, valharuts are champions of law itself, purely designed to combat the forces of entropy. They are most often seen around and outside the Mechanical city of Axis, leading campaigns against chaotic incursions under the instruction of their axiomite creators. Valharut will not negotiate or compromise with those it perceives as agents of disorder. If you are aligned with the forces of law, you may find an ally in the valharut, but those who embrace chaos, and especially entropy, should expect no mercy from this relentless enforcer of order. Doomguard beware!

Kolyarut

Who seek to enforce contracts, oaths and promises

LN; CR 12 [PF1e], CR 20 [5e] *

The kolyarut is an inevitable dedicated to enforcing oaths, contracts, and bargains, ensuring that promises are kept and debts are paid. Appearing as tall, clockwork humanoids completely encased in metallic armour, with flowing robes atop, they are nonetheless able to blend seamlessly into mortal societies using their magical abilities to alter their appearance. Kolyaruts are highly social, for inevitables, often engaging in diplomacy or even light subterfuge to investigate oath-breakers before striking. They are patient and methodical, and also strategically merciful, attempting to weaken their targets while avoiding unnecessary bloodshed. Their mission is impartial; they care not for the morality of the agreements they enforce, only that they are upheld. Cutters dealing with a kolyarut should be cautious but respectful. These constructs are logical and, unusually for inevitables, even willing to negotiate if it serves their purpose,—but they are relentless once an oath-breaker is identified. If you have broken an important promise or attempt obstruct their mission, expect no leniency—they will pursue quarry across planes if necessary. The Fated are known to use kolyarut heavies-for-hire to collect on debts they are owed.

Yarakhut

Who protect cultures from advanced magic and technology

LN; CR 14 †

The yarahkut is an eleven-foot-tall inevitable tasked with preventing the misuse of advanced magic and technology—particularly in regions or cultures unprepared for such powers. Constructed from gleaming metal and adorned with intricate bladed wings, it has three identical faces that gaze in different directions, with glowing eyes. Its two sets of arms—one equipped with razor-sharp claws and the other more humanoid—allow it to both fight and manipulate objects with precision. Yarahkuts are relentless in their mission to confiscate or destroy items deemed too dangerous, using magic to disassemble objects and an aura that disrupts mechanical weapons and advanced technology. These inevitables are meticulous in nature and highly strategic, often working through networks of agents to track dangerous items before stepping in and acting directly. They are not easily deterred and will pursue their quarry across planes if necessary. If you possess dangerously powerful magical or technological artifacts, expect the yarahkut to confiscate them without hesitation, potentially even erasing your memory of the item—or simply eliminating you entirely if it deems you too dangerous to leave alive.

Marut

Who hunt down those who would cheat death

LN; CR 15 [3e, PF1, PF2e]; CR 25 [5e] *

The marut is a towering mechanical colossus, standing over twelve feet tall, with a body of polished obsidian-like metal adorned in ornately decorated armour. Its glowing red eyes and seamless construction give it a truly imposing presence. Maruts are tasked with enforcing the natural law of death, hunting down those who unnaturally extend their lifespans through means such as undeath or powerful magic. They are relentless in their pursuit, tracking targets across the planes, and employing overwhelming force to ensure that no one escapes the inevitability of death. Unusually, the Fraternity of Order employ a marut also enforce contracts forged in the Hall of Concordance, ensuring that agreements bound by cosmic law are upheld. Cutters encountering a marut should tread carefully, as these constructs are nigh-unstoppable once they identify a target. They are impartial and logical but utterly unyielding in their mission, often working alongside psychopomps who share their mission to deliver reluctant souls to the Underlands. If you are not the subject of their pursuit, they will not harm you unless you interfere. However, those who defy death will face the full might of these interplanar enforcers, who will not rest until their task is complete.

Quarut; Aevarut

Who punish those who tamper with time and space

LN; CR 17 (MR 7)

The quarut is a towering inevitable charged with safeguarding the integrity of time and space, ensuring that no mortal or immortal disrupts the natural flow of events or tampers with reality. Standing over twelve feet tall, it has a humanoid form crafted from polished bronze and adorned with intricate clockwork mechanisms and glowing runes that pulse with temporal energy. Its piercing, mechanical eyes constantly scan for anomalies in the timeline, and its magical abilities make it a relentless enforcer against those who manipulate time or create paradoxes. Quaruts are particularly focused on punishing those who use magic like time stop, engage in reckless time travel, or attempt to rewrite history. Bloods attempting to use time-altering magic or reality-warping effects should be aware they quarut cannot be bribed or reasoned with if they perceive a threat to temporal integrity. Avoid drawing their attention by using time-related magic sparingly and responsibly, as once a quarut identifies you as a transgressor, it will pursue you across dimensions and time until the anomaly is corrected or you are eliminated.

Hykariut

Who suppress rebellions and revolutions

LN; CR 18 †

The hykariut are towering inevitables, standing fourteen feet tall and weighing 5,000 pounds. These constructs were created to suppress rebellions and extinguish revolutions that threaten widespread chaos. Their imposing forms are composed of stone and spiked steel armour, and they wield massive axiomatic warhammers that radiates the power of law. Hykariuts are not concerned with minor uprisings but focus on large-scale insurrections that risk destabilising entire regions or societies. They are equipped with abilities to scatter crowds, or to condemn individuals as chaotic. Despite their intimidating appearance, hykariuts can show restraint, and will usually attempt to resolve conflicts through reason or nonlethal force before resorting to violence. While they may engage in debate or negotiation if they believe a peaceful resolution is possible, they will not hesitate to crush ideological leaders or rebellious movements if they pose a significant threat to stability. Avoid drawing their attention by steering clear of revolutionary activities or chaotic uprisings, as once a hykariut identifies a target, it will pursue its mission with unyielding precision until the rebellion is quelled and order is restored. It should be noted that the hykariut have never acted against the Hands of Havoc, despite frequent petitions from the Guvners—something which causes the anarchists a strange mixture of relief but also annoyance—are they really not seen as a great enough threat?

Varakhut

Who uphold the sanctity of divinity itself

LN; CR 19

The varakhut is one of the most powerful and rare inevitables, created to uphold the divine order and protect the sanctity of deities and their domains. Towering at over fifteen feet tall, its form is both majestic and intimidating, resembling a humanoid figure crafted from gold and obsidian, with radiant wings of light and intricate celestial engravings covering its body. Varakhuts are tasked with hunting down those who seek to usurp, destroy, or impersonate gods, as well as mortals who attempt to ascend to divinity through illegitimate means. Their immense magical powers include abilities such as plane shift, wish, and devastating elemental attacks like lightning swords and fire whips, making them formidable enforcers of cosmic law. These inevitables are unyielding in their mission to preserve the balance of divine authority. If you are not directly interfering with the divine order, a varakhut is unlikely to target you, but any perceived threat to the gods or their domains will provoke its full wrath. Negotiation is rarely an option, as varakhuts prioritise their mission above all else and wield overwhelming power to ensure success. Athar view these inevitable with a strange mixture of awe, fear and glee—why would so-called ‘divine’ powers need a clockwork enforcer to protect them, after all?

Rokyamut

Who defend the laws of mathematics and geometry

LN; CR 19 †

The rokyamut is a colossal inevitable devoted to defending the immutable laws of mathematics and geometry, ensuring that reality adheres to its fundamental principles. Standing an immense sixty five feet tall and weighing two hundrd tons, it has the lower body of an elephant and the upper body of a four-armed, barrel-chested giant, with exposed gears and cogs at its joints. Above its head floats a glowing halo of mathematical symbols, which it can conjure into its hands as brilliant energy starknife weapons. Rokyamuts are tasked with defending the planes against those who bend or break the fabric of reality, such as chaotic outsiders, aberrations, and cosmic entities that defy natural laws. Their very presence stabilises space, nullifying teleportation and other reality-altering effects. These inevitables are tireless juggernauts that will not hesitate to confront anyone they perceive as a threat to the stability of the multiverse.

Lhaksarut

Who reinforce the boundaries between the planes

LN; CR 20 †

The lhaksarut is a towering and intricate inevitable tasked with enforcing the sanctity of interplanar portals, planar travel, and the natural boundaries between dimensions. Standing over twelve feet tall, it has a humanoid upper body crafted from gleaming brass and blue steel, adorned with arcane symbols representing planar stability. Its lower body is a mass of shifting, clockwork tendrils that allow it to move fluidly across any terrain or even through planar rifts. Lhaksaruts are relentless in their mission to prevent unauthorised or reckless planar travel, targeting those who destabilise reality through improper use of portals, summoning magic, or dimensional breaches. They are able to lock down portals and gates, and banish outsiders. These inevitables are impartial but unyielding in their enforcement of planar laws and will always intervene if they perceive a threat to the multiverse’s stability. Those who recklessly tamper with planar boundaries will face the full force of the lhaksarut’s power, including its ability to track offenders across planes and seal off escape routes. Lhaksarut are also thought to be involved in many cosmic realignments, where portions of Outer Planes are transposed from one part of the Great Ring to another—either to try and stabilise such events, or to encourage them if they are truly required. They have also been kept busy since the Doomguard created and released entropes to dissolve the borders between the Inner Planes.
