Jiralhanae

The Jiralhanae, known for short as Jirals by the Covenant and as Brutes by humans, are a robust bipedal sapient species native to the planet Doisac and the last species to be incorporated to the Covenant collective. They are known for their incredible strength and durability, and are regarded by many as a savage species due to their territoriality, aggressive tendencies and tribal social structures. The Jiralhanae have an ancient mutual animosity with the Sangheili, originating from nearly a millennium of irregular conflict between the two species in the spinward side of the Orion Arm before the Jiralhanae's assimilation to the Covenant.

Etymology
"Jiralhanae" allegedly means "Thrice-risen ones". The name's origin is unclear, and it does not directly mean anything in any known modern Jiralhanae language or dialect. Some Covenant scholars, by drawing similarities to the modern grammar of semi-isolated Jiralhanae groups living in the Nuemian Boundary and the Inner Corelight Reefs, have concluded that the popular meaning may have some basis in reality. San'Shyuum linguists have postulated that the original name may perhaps have been Yrrolhanag (yrro= to rise, to lift up + ol-hann= three times + -nag = suffix used for peoples or ethnic groups).

However, alternate theories have been presented. Some Covenant sources suggest it originated as the name of one of the ethnic groups or tribal associations that first raided Covenant colonies in the coreside spinward regions of the Holy Ecumene. Likewise, it is uncertain if the name began as the Jiralhanae's own endonym or an exonym by the Sangheili based on what they thought the Jiralhanae called themselves, though today most Jiralhanae claim the name solely as their own. Likewise, most Jiralhanae embrace the "Thrice-risen ones" meaning as being prophetic of their history.

There are many variations of the name in different populations, e.g. Jirahhanae, Diraanae, Yrohane, and Tira Hannaeg. In some diaspora populations in longtime contact with Sangheili, such as those of the Oarthen Threshold, the name has even "Sangheilized" into the form Jiralanee, without conscious effort on either party's part, and Doisac-born Brutes often mock the "farborn" for this. Whatever the original name may have been, the Covenant formally uses "Jiralhanae", which has led to some degree of standardization also taking root among the clans most involved with the Covenant.

Age of Legends and the Wars of Dominance
The first industrial age came to the Mbreultu continent during a time of flux, circa 900 AD. Old alliances were breaking down, and charismatic new leaders were forging nations from disparate tribes. New sciences ended the old cycles of famine and want. Most importantly, philosophical teachings broke out of ancient monastic schools and were embraced even by the peasants. The ways of the old gods were found to be hollow. In their place came an imperative for the men to cultivate virtue and knowledge.

The industrial revolution and the philosophical teachings spread across Mbreultu and the Roghan sea to the rest of Doisac. In these times of tumult, Jiralhanae individuals forever left their mark on history by overthrowing or renewing ancient institutions. This Age of Legends reached a climax with Doisac's first world war, a conflict between the coast nations of Mbreultu and an emergent steppe kingdom that had already spread across three continents.

The heroes and warriors of this age would come to be revered much in the same way that the Hellenistic Greeks revered the heroes of the Iliad. They, their weapons, and their armor became legendary after the Great Immolation even after their philosophies were ignored. Modern day implements such as spike rifles, Brute shots, and even the power armor favored by many tribes is patterned off the weapons used in the Dan Rh'tol Invasion.

Space Age and the Great Immolation
Over time, the Jiralhanae developed industrialization and continent-spanning governmental structures, these being largely despotic, imperial or feudal arrangements. They eventually discovered spaceflight, but their attempts at reaching orbit were severely hampered by Doisac's high gravity. Although the native exotic material known as Tyrkal could be used to create rudimentary gravitic devices, the technology was still in its infancy at the time, and did not scale up well. They were unable to build chemical rockets powerful enough to put meaningful amounts of material into orbit, and resorted to using open-cycle nuclear thermal and nuclear saltwater rockets instead. The fallout from these rockets caused massive ecological damage and exacerbated their already-existing resource shortages. Famines triggered resource wars, which led to all-out nuclear war that knocked the whole planet back into a pre-industrial era. This was known as the Great Immolation, and it is one of the most defining events of Jiralhanae history. Although the exact timing is unclear, the Great Immolation is commonly believed to have occurred circa the 14th century.

This is where the Covenant would have found the Brutes, had it not been for Doisac's moons and a team of deep-space miners. The Brutes weren't idiots. They could see the writing on the wall. They knew a crunch was coming, and even the ones who didn't wanted to get away from the overpopulation and chronic shortage of food and clean water. In the brief time that the Brutes had spaceflight, perhaps thirty million of them relocated to arcologies on their moons. Much of this extensive space presence owed to the arms race between the major Jiralhanae empires of the time, which quickly spread out into Doisac's orbital space in a manner comparable to Earth's Space Race in the 20th century. Orbital infrastructure and manufacturing are vital to any species wishing to expand out into space, but for the Jiralhanae, this was doubly so. Every gram sent into space was incredibly costly, both economically and environmentally, and every satellite, ship or probe manufactured in orbit by Jiralhanae already in space was a major saving on the surface.

The orbital settlements would likely have been destroyed by infighting if someone hadn't intervened. The Brutes never invented the slipspace drive. They had nowhere to go. Some records and oral traditions suggest that missions to the Oth Sonin system's other bodies were attempted at the height of the Jiralhanae space race, but none of these yielded permanent colonies.

Expansion
This is where the Gryunjalla entered the picture. "Gryunjalla" is an old Jiralhanae word for 'prospector', which the group that approached the Jiralhanae colonists seemingly were: a team of miners operating far from their civilization seeking to exploit the Oth Sonin system. They sold the Brutes slipspace-capable ore freighters in exchange for the right to mine various near-Doisac bodies. There has been speculation as to why the Gryunjalla did not simply take those resources, as the Jiralhanae in their weakened state would've been quite powerless to resist. Their willingness to trade has been attributed to cultural factors, as the Gryunjalla were exceedingly polite in all their interactions.

These ore freighters were slow, but very sturdy, and the Brutes used them to colonize dozens of worlds. They were carried even further afield by the Gryunjalla, who would hire the Brutes out for manual labor to mine this planet or that one, only to abandon the Brutes in place once the operation was finished. This era of peaceful expansion must have lasted for several generations before the Brutes took up their old pastime of fighting each other.

Warlords got ahold of the ore freighters (By now, the Gryunjalla had sold them well over a hundred) and turned them into missile boats and carriers. Many systems developed the industry -both planetside and in space- to manufacture warships and strike craft. But the Brutes never developed the slipspace drive, and in fact required the Gryunjalla's help to maintain the ore freighters.

Each of the warlords seized a planet and forced the population to pay tribute. Warlords fought for dominance over the different colonies and the right to collect tribute therefrom, skirmishing until one side or the other was forced to retreat from orbit. If you were a Brute born in space, you labored and you fought for a warlord, and maybe you lived long enough to make a name for yourself. If you were born planetside, then your life was wasted in one tribal war after another, and maybe you did well enough to care who you paid tribute to. On the other hand, it didn't pay to care too much. The warlords weren't above dropping rocks and nukes down the gravity well.

This state of affairs lasted until the Classical Spinward Migrations out of the Spinward Median territories reached the Oarthen Threshold. The Covenant Empire and the Brutes expanded into each other's territory.

Covenant contact
The contact with the Covenant collective was the beginning of a new era for the Brutes. They raided these frontier worlds, but they also settled on them. High Charity's attention was turned elsewhere, so the Kaidons of these border worlds simply hired different bands to fight proxy wars against each other, and they paid with technology and old starships.

This broke the Gryunjalla's control over the Brutes, possibly for the worst. With the influx of old Covenant warships, the Jirals no longer relied on their benefactors for access to interstellar travel. The tribal warfare in the Brute territories got even nastier, and this spilled out into the Covenant frontier. This is where the bad blood between the Brutes and the Elites came from. Billions of citizens on the frontier fought hordes of Brute raiders in a dozen brush wars, and each side was too fragmented to put an end to the fighting.

At the same time, the Brutes were picking up the Covenant religion, both from the worlds they traded with and from missionaries who made the journey to Jiralhanae colonies. This caused a slow divide between the Brutes and the Gryunjalla. It appears many of the warlords became convinced that the Gryunjalla prospectors were stealing Forerunner relics from their territories.

While these bush wars were being waged on the frontier, High Charity did nothing, even though stories of the Jiral brutality were circulating through every major starport. Clans throughout the Empire were pledging warriors and warships to the fight, though few of these made it to the frontier.

In the later centuries of this period, the Jiralhanae were deployed as auxiliaries by the martial ministries of the Covenant proper with increasing regularity. Jiralhanae auxiliary legions became quite well-liked by several of the ministries as they had no bonds to Sangheili clans nor were they bound by the restrictions of Shal'annu. This meant that Jiralhanae auxiliaries could be deployed as "neutral" security forces in conflicts involving feuding Sangheili houses, for example.

Meanwhile, the Jiralhanae became a source of fascination for the Covenant's intelligentsia. The San'Shyuum high society of High Charity in particular found the Brutes' often-blunt ways appealing and vigorous in contrast to what they saw as a cultural stagnancy in the Covenant. This gave rise to the Primalism trend, in which San'Shyuum writers and bureaucrats idealized the Jiralhanae's supposedly pure and unsophisticated nature. The Prophet of Truth, while hardly an intellectual by San'Shyuum standards, was no doubt influenced by the prevalence of Primalism in the cultural zeitgeist, as were many of his Loyalist allies.

Assimilation
A defining moment in the developing Covenant-Jiralhanae relationship came when a warlord named Charactus sacked the Diocese of Ettretritan, a sanctuary-world on the way between Zhoist and the Covenant's core territories. That got High Charity's attention. Holy war was declared, fleets were mobilized, and the fighting was over within the year. Unlike the much more drawn-out Human-Covenant War, which had the Covenant encroaching in unknown territory, the slipspace routes to the major Jiralhanae colonies were already familiar to the Covenant, having been mapped by missionaries and traders over the past centuries.

The warlords who didn't flee into the dark were killed or captured. Meanwhile, the Brute colonies were already in the habit of paying tribute to whoever controlled high orbit. The Covenant effectively slotted themselves into the existing power structure, and then won the eternal gratitude of everyone on the surface by ending the fighting once and for all.

Around this time, Doisac was finally recovering from the nuclear war. Some of the evangelical ministries had launched missions to that planet, but the planet was only just consolidating under the rule of the Co-Dominium of Doisac. As per Covenant custom, the Jiralhanae were not considered to be a part of the Covenant until their homeworld was conquered, even though tribes have lived within the Empire for hundreds of years as a fringe race.

From that point on, the Covenant has been busy trying to civilize the Brutes to their standards, and the Brute societies have been modernizing rapidly, when they don't just pull up stakes and move into settled regions of the empire. This was partly facilitated by deliberate programs by the High Council, as the integration of a new species into every area of Covenant society was part of the assimilation process. In some respects, the Brutes have bought into the Covenant way of life, especially the religion. In other ways, they've barely assimilated, and most of them haven't even had time to assimilate into the Covenant Empire. They never accepted their spot in the pecking order of the caste system, and there remains a lot of bad blood with the Elites in particular.

The Covenant's expansion into Jiralhanae space and beyond likely expedited the hegemony's discovery of humanity just three decades later. The Human Sphere is located relatively close, in galactic terms, to the Brutes' expansion regions in the coreside-spinward side of the Holy Ecumene. The Jiralhanae's assimilation triggered further development of the region as well as nearby outlying marches such as the Kalosi Reach, where the first mission into human space would be launched three decades later.

The Great Schism
Since the Great Schism and the defeat of the Torchbearers as a united front actively fighting the Schismatics, the Jiralhanae have splintered into numerous independent chiefdoms. Many of these sought peace with Schismatic factions by the 2650s to retain their autonomy as the Concord of Reconciliation grew more powerful and pushed deeper into Jiralhanae territory. Some war-chiefs fled beyond Jiralhanae space known to the Covenant.

Culturally, the Jiralhanae worlds splintered between those who retained their faith in the Covenant religion, though even this took various forms on different worlds as Covenant beliefs syncretized with the native Jiralhanae faiths. Some discarded the Covenant religion altogether, often as a rejection of Tartarus' ideals, though it did retain a strong foothold across the Jiralhanae meta-society. Many Jiralhanae communities romanticized and sought to emulate the Covenant and its social institutions, which would give rise to various pretender Covenant factions, many of them short-lived. The largest and most notable was the Eternal Covenant, a relatively decentralized collection of Jiralhanae loyalist groups with a small number of San'Shyuum acting as figureheads. However, the Eternal Covenant no longer had the capacity to carry out large-scale campaigns, and its member polities would feud with one another as frequently as they did with outsiders.

Biology
While now recognized independently-evolved aliens, the Jiralhanae have convergently evolved various characteristics commonly described by human xenobiologists as pseudo-ursine, simian and pachydermian. Early on into humanity's encounters with the Covenant, it was speculated that Jiralhanae may be related to terrestrial fauna - the most notable candidates brought forth were higher primates and bears. Alongside the dinosauroid Kig-Yar, this would make them the first potential examples of sapient out-of-place biota known to humanity. However, autopsies, DNA analysis and intel on Jiralhanae reproduction quickly dispelled this notion, showing that the species has no link to Earth life.

Anatomy and physiology
The original Jiralhanae ancestors evolved in the vast megafloral jungles of Doisac, leading to an anatomy not unlike tree-dwelling creatures of Earth such as primates. The generally higher average temperatures of Doisac's climate led the Jiralhanae to a preference for tropical climates and warmer weather - something accommodated for thanks to Doisac's fairly evenly-spread temperature gradient. As such, the natural fur the Jiral grow exists primarily for the purposes of being a natural form of protection against the environment. Due to the high presence of contaminants, parasites and other particulates in Doisac's sky, the Jiralhanae grow thick fur to protect against these atmospheric dangers. This fur is also useful against more physical threats such as venomous plants and even fending off attacks by fauna or other Jiralhanae; when grown particularly matted, the fur serves as a form of armour protection against weapons.

Due to their preference for warmer climates, the Jiralhanae fur is often useful for those living in the higher or more polar regions of Doisac, and those travelling often on the sea. Jiralhanae sea-raiders were renowned for growing their fur to be unkempt and matted, useful as both protection and a tool of intimidation. Due to this warmer temperature preference, the Jiralhanae expected to spend significant amounts of time on other worlds may grow out their fur to help acclimate to the cold. This was especially prevalent during the Human-Covenant War, during which Jiralhanae troops were often deployed onto glassed worlds undergoing a nuclear winter. This has given other species a particular view of the Jiralhanae based on this sterotype (in-part perpetuated by Brutes wishing to use this to their advantage for fear factor), when in reality most Jiralhanae put extensive effort into maintaining their fur. Tribal markings and shaving is common, with various patterns (combined with tattoos and other features) used to denote position and social status. A Jiralhanae's fur is a key part of Jiralhanae culture, with the ability to grow a thick mat of hair - even when on long sea voyages - seen as a sign of health and virility.

Due to Doisac's near-constant state of darkened skies, the Jiralhanae have evolved their senses as not to rely on vision as much as other species', instead possessing highly effective auditory and olfactory senses. The latter especially is used in communication, with the Jiralhanae emitting pheromones to correspond with various kinds of mood or emotional state. This method of communication is pivotal in Jiralhanae society and, when combined with regular body language, allows Jiralhanae to have full conversations with - what would appear to a Human - only a series of grunts and barks. Conversely, the lack of pheromones used by other species puts the Jiralhanae at a disadvantage in communication, with more care and effort required to converse with other species - leading to many Brutes tasked with dealing with other species' being particularly irritable in their encounters. Pheromones are particularly commonly emitted in younger Jiralhanae, with more mature individuals learning to control their pheromonal outbreaks as they age. Pheromones are unique to each individual Jiralhanae, giving each Brute a distinctive smell based on his surroundings and emitted pheromones - an effect amplified with unkempt or unwashed fur. As a result, Jiralhanae hunting parties may choose to shave their fur to help mask their scent better.

Jiralhanae exhibit a pattern of sexual dimorphism relatively expected of their xeno-mammaloid biology, with males of the species being generally larger and more muscular than the females. Jiralhanae give birth to litters of live offspring of up to a dozen individuals. Jiralhanae newborns are not much larger than human ones, and are completely helpless until around two years of age. While gestating, Jiralhanae females accumulate additional fat reserves meant to support their offspring. As it directly correlates with a female's ability to produce healthy offspring, a "healthy" amount of fat is considered an attractive trait in many Jiralhanae cultures.

Gravity adaptation
The Jiralhanae's robust physiques owe much to their homeworld's high gravity of 2.1g. They take great pride in this, and there is a common belief that gravity builds not only strength, but also character. Along with certain quirks and limitations in their natural spatial awareness and sense of orientation, this is one reason many Jiralhanae dislike space and spending time in low or microgravity. Zero-gravity environments and freefall tend to cause intense vertigo and nausea, and though most are capable of enduring this, only a select few can fully adapt to life in space. The Jiralhanae's threshold for debilitating muscle and bone atrophy is at around 0.8-1g of prolonged exposure, where most other species can withstand half that or less. This also led to even the early Jiralhanae colonies on Doisac's moons quickly developing artificial gravity devices. Unfortunately, it also often causes Jiralhanae who spend time on low-gravity worlds to develop various physiological conditions, and many Jiralhanae consider it taboo to procreate on such worlds as it is believed "lightborn" offspring will grow up to be weak.

Another adaptation found in Jiralhanae is a network of sponge-like blood vessels found between their shoulders and in their upper body; these vessels act as flow restrictors for the Brutes' blood to prevent blood from reaching or draining from the head too quickly when standing and causing death via exsanguination. This adaptation is similar to those found in some taller fauna on Earth and also exhibited in other life hailing from high-gravity worlds such as the Sharquoi. This network has the added benefit of being able to restrict the flow of blood to damaged parts of the body as a natural response, allowing Jiralhanae to enter a rage state even when severely injured and keep fighting long past the point at which any other species would have bled out entirely.

In addition to the various ethnic groups already present across Doisac, various diaspora populations of Jiralhanae on other worlds have diverged from the species baseline. While many colonial populations sought to settle high-gravity worlds, and some managed to, most had to make do with what they had. Jiralhanae lightworlders are typically taller but less physically robust than their counterparts born on Doisac or other worlds with a comparable gravitational pull, which — coupled with the homeworld's harsh conditions — is often used by Doisac Jiralhanae to justify their sense of superiority. The lightworlders are often called Larthanae, a pun of sorts meaning "Skinny ones" or "Delicate ones". A common stereotype prevails among the so-called "pure" Jiralhanae (which those either from Doisac, or high-g worlds in general, often identify as) of the Larthanae as weak and submissive, and they are frequently mocked and humiliated by heavyworlders of a particularly spiteful temperament. In general, the lightworlders can do little but accept their lot while trying to ignore the indignity, though some struggle to prove themselves by routinely spending time and exercising in high gravity. This rarely does much to impress heavyworlder Jiralhanae, who are only convinced by concrete displays of power and dominance. However, it has also contributed to the splintering of the Jiralhanae meta-society, with many groups of Larthanae actively seeking to distance themselves from Doisac's ways both in terms of physical distance and culture.

Jiralhanae shipmasters frequently run their ships' artificial gravity at Doisac's 2.1g or close to it, though if other species (particularly Kig-Yar, San'Shyuum or Yanme'e are present, this may not be seen as feasible. With their hardy body plans and exoskeletons, Unggoy can withstand high gravity surprisingly well, though above a certain point the Jiralhanae have found it hinders their productivity; to Kig-Yar, Yanme'e and San'Shyuum, it can be lethal. Some Jiralhanae crews have also been known to use this as a show of dominance, intentionally turning up their ships' artificial gravity for the discomfort of other species, especially Sangheili and even lightworlder Jiralhanae, during diplomatic meetings and boarding operations alike. Similar issues apply to other species landing on Doisac, which San'Shyuum in particular are physically incapable of doing without constant gravitic assistance.

Culture and society
Collectively, the Jiralhanae can be said to possess a pervasive longing for their pre-Immolation past, of which the ruins that cover much of Doisac serve as a reminder. Though this cultural undercurrent is most common on Doisac, it does occur on the species' colonies as well. Some colonies view the homeworld in a reverent, almost mythic light, though this is far from universal, and it is not uncommon for Jiralhanae colonies to regard Doisac much like human colonial separatists do Earth. This issue has recently become particularly polarizing due to Tartarus' emphasis on Doisac's importance in his campaign to unite the Jiralhanae. Many warlords throughout history have and continue to appeal to the species' near-mythic glorious history in their efforts to garner support, usually citing descent to this and that empire or ruler. Such campaigns are necessarily ethnocentric, as another half or more of the Jiralhanae population will claim descent to the opposing empire. Attempts to unite the Jiralhanae on a species-wide level have had only limited success due to the species' deeply-rooted tribalism. Tartarus managed this for a short time by ignoring old customs and institutions, though this did not come without significant blowback, and it is likely some of the consequences of Tartarus' short reign are yet to set in. The Banished have recently attempted to build a pan-Jiral culture by evoking the species' former glory on a more general level while integrating native tribal and pack structures into their hierarchy, though it remains to be seen how lasting this will be.

Governance
Despite common assumptions, the Jiralhanae are not predisposed to despotism. They're more aggressive than the other species active in the Orion Arm, but they're also cooperative, and their better-structured cultures teach the young how to channel that aggression into useful outlets. What Brutes have had a problem with, ever since the lead-up to the Great Immolation, is scaling society up past the tribal level. There were nations with global reach on Doisac, and supranational organizations and alliances as well. But civilizations have a natural cycle of growth and decay, and the most prominent of those nations were decadent and corrupt at the worst time possible, when there was a resource crunch. After the Great Immolation, the Grunjalla spread the Brutes out so far that few worlds had population concentrations big enough to call a nation. Tribes naturally organized themselves, claimed territory, and built.

At about the same time when many worlds finally had nations big enough to come into conflict with each other, the Gryunjalla-built ore freighters fell into the hands of warlords. The warlords subsisted by conquering worlds and extracting tribute from them. This meant that they invested in building launch infrastructure so that the tribute could be delivered, but it also meant that their boots were on the metaphorical throat of the worlds they conquered. Eventually, this matured into a system of tribal confederacies, where many tribes were linked together by lines of travel, trade, and a shared culture inherited from a common origin point. Then the Covenant came in, killed off the warlords, and established themselves as a new overlord. The transition was pretty seamless because the Brute colonies were used to paying tribute to whoever controlled the orbits, but the Covenant brought a short-lived reprieve. Travel was no longer restricted, and industries were freed from manufacturing spaceship parts and luxury goods for the Warlords. This led to rising tensions and would have led to all-out war, reminiscent of the bush wars of Humanity's Inner Colony Wars. The relationships between the tribes on most worlds were allowed to develop out of equilibrium, because violence was held off the table by the threat of the Warlords to drop rocks if conflict threatened their tribute.

Had things gone otherwise, High Charity would have spent decades wandering through Brute territory, resolving conflicts and bargaining territory transfers to restore order among the tribes. This obviously didn't happen. Instead the Brutes got Tartarus, who preyed upon the social malaise within the tribal confederacies by turning the young against the old. He promised his followers power through ambition and victory on the battlefield. This worked, but it would only work in the short run. When you unfetter the ambitious and fuel your rise to power with the burning of old social institutions, there's only one way it can end.

Naming conventions
A characteristic particular to Jiralhanae names are maturity suffixes, a type of suffix added to one's name typically following some form of initiation rite or a given amount of experience in battle. In this capacity, the suffixes "-us" and "-um" predominate on Doisac, along with some colonies. Some clans do not use such suffixes at all, while others use variants of the more common ones such as "-ox" or "-ax", which are essentially the result of phonological drift. A number of variations exist even on Doisac, like "-or" or "-r" (as in "Castor") and "-un" (as in "Orsun"). In Tartarus' coalition and the Covenant, many Brutes adopted the -us or -um standard to fit in with the mainstream.

Many Jiralhanae names are also Latinized to some extent as part of a translation convention; Tartaus' real name might be something like "Tartharrosh" and possibly include sounds foreign to the human ear; as such they're often simplified in a form more understandable to humans.

Material culture
Jiralhanae material culture is dominated by ruggedness and practicality, traits necessitated by both Doisac's high gravity and the species' imposing physiology. Though utility is prized over art, the species nonetheless has rich artistic and decorative traditions, as shown by the crumbled opulence of Doisac's great cities or the intricate geometric designs used to decorate Jiralhanae equipment and weaponry.

Stone- and metalworking have always played a large part in Jiralhanae technology and material culture, from their earliest civilizations to the post-Immolation era. Though the dark ages saw Jiralhanae smithing endeavors mostly turned to destructive ends, they continue to produce many surprisingly sophisticated pieces of metalwork. Some of these items became coveted collectibles to Covenant marcher lords in the early days of the Jiralhanae-Covenant contact, and even pre-Immolation artifacts are known to have ended up in the private collections of wealthy kaidons.

A noted recurring motif of Jiralhanae art, architecture and design is the frequent use of trilateral radial symmetry. Trilateral forms occur in across the species' material culture, from imagery and decorative ornaments to buildings and even starships. It has been suggested this motif has its origins in early Jiralhanae religious and philosophical beliefs influenced by Doisac's three moons and the resulting cycles on the planet.

Technology
Native Jiralhanae technology is robust and while superficially crude, many of their technologies conceal surprisingly advanced mechanisms. Much of their original technology was lost with the Immolations, though some industries were retained, especially in the orbital habitats. These factories, coupled with remaining examples of ancient weapons and vehicles, became prized possessions and heirlooms for dominant clans in the subsequent dark ages. Meanwhile, many quality-of-life and medical technologies were irrevocably lost as warlords prioritized weapons development. Following the species' assimilation into the Covenant, the hegemony's ministerial assembly forges began reproducing many of the Jiralhanae native weapon designs, though by that time, various marcher armories had unofficially produced versions of them for some time.

One of the quirks of the Jiralhanae's technological path is their native gravitic technology. They are the only known species to have developed gravitics before they left their homeworld's gravity well. This is thanks to what the Jiralhanae call Tyrkal, a naturally-occurring material that exhibits properties similar to zenostium-based nanolattices used in paragravity systems. Found on Doisac, Tyrkal allowed the Jiralhanae to harness basic forms of contragravity by the time they reached the atomic age. At the height of Doisac's industrialization, it was widely used for weapons technology as well as vehicles and aircraft to provide additional lift or lighten their weight in the planet's crushing gravity. Similar to most other contragravity systems, however, its effectiveness decreased further away from the planet's surface. This made it less useful for providing orbital launch assist, prompting the Jiralhanae to resort to environmentally-devastating open-cycle nuclear thermal rockets in order to get into space. In orbit and on Doisac's moons, Tyrkal-based paragravity systems were used to simulate a Doisac-like gravity due to the Jiralhanae's physiological needs.

The Jiralhanae largely utilize fossil fuels and nuclear fission power in their native technologies, though various alternate arrangements came to be used locally by the interstellar colonies. In their industrial age, photovoltaics never advanced far enough to be viable for large-scale power needs, and virtually all of their space technology is nuclear-powered. The orbital colonies retained the ability to manufacture fission reactors, some types of nuclear weapons and basic nuclear thermal rockets after the Great Immolation, and these would frequently be used on the ore freighters turned raiding vessels in the Gryunjalla era. Perhaps the species' most impressive achievement is a high-thrust nuclear engine comparable to the nuclear saltwater rocket, which humanity never perfected before the advent of fusion. Such rockets were evidently volatile but also the Jiralhanae's most effective option for surface-to-orbit transit vehicles, some of which were gigantic in scale. After the Immolations, the ability to manufacture such engines was apparently lost.
