In my years as a Magister-Naturalist of the Frontier, I have devoted countless expeditions to unraveling the mysteries of the creatures that lurk on the fringes of the Germanic Empire, and few have fascinated me as much as Homo ferox orcinus, commonly known as the territorial parasitic orc.

  I remember my first incursion into the wild northern lands, where I spent three months hidden among ancient ruins, observing a basic unit of these eusocial predatory hominids with obligatory parasitic reproduction. It was astonishing to discover that their society is not based on kinship or emotional bonds, but purely on physiological dominance imposed as an unbreakable biological law. They do not form stable peoples like humans, but rather territorial pressure structures that expand and contract like a living organism—and I didn’t realize this until I saw an entire group disintegrate into chaos when their alpha was felled by an arrow from an adventurer I was traveling with.

  The morphology of these beings is a testament to brutal adaptation: they measure between 1.9 and 3 meters in height, weigh from 130 to 340 kilograms (at least for the specimens I managed to weigh; with large bounties at stake, adventurers prefer to ignore the bodies and cut off the heads as proof of success), and their life expectancy ranges from 25 to 40 years. I believe they could live longer if they weren’t so violent, though that assumes constant combat, which is their daily norm. Their dominant traits include extreme bone density that allows them to withstand blows that would shatter a human warrior, accelerated healing—I have seen deep wounds close in a matter of hours during an ambush I witnessed in the hills of Eldarath; one orc endured cuts and arrow shots—at least the attempt to capture that magnificent 3-meter-10 beast was a failure—a resistance to pain that lets them ignore what would be mortal injuries to most, hyper-reactive aggression that erupts at any threat, and a continuous war metabolism that keeps them in a perpetual state of alertness.

  Their brain prioritizes immediate response over any strategic planning, making them intellectually equivalent to a young boy but physically equivalent to a permanent adult predator. This shocked me enormously when, during one of my investigations, I tried to reason with a captured beta—only to realize that its mind does not process dialogue, only dominance. It became a servant in training until an external adventurer saw an orc meditating and attacked it from behind. We had spent three months getting it to follow orders; other attempts at domestication have failed.

  The social structure revolves around an absolute biological hierarchy with clear functional types: the alpha as the reproducer and center of cohesion (these are the tallest—it’s a shame the Empire destroyed a specimen said to measure three and a half meters; I could have captured and cataloged it as an example of this species’ potential), the betas as subordinate combatants, the juveniles as future combatants, and the incubators as parasitized hosts.

  The alpha leader is the only one who can reproduce—not by cultural norm but by chemical inhibition; it secretes suppressive pheromones that prevent the reproductive maturation of the others, and as long as it lives, no other orc initiates the parasitic cycle. I must thank the alchemists for detecting this issue and my beloved wife Johana, who realized this process with a dozen betas in the presence of a captured alpha.

  When it dies, the betas enter a violent frenzy until one dominates, and a new alpha emerges in less than 24 hours. I experienced this up close during a hunt with a group of mercenary adventurers, where we killed an alpha and the ensuing chaos forced us to flee, leaving two companions behind who did not survive the frenzy.

  The basic unit is usually 40 to 100 individuals—a stable size that allows territorial control without food collapse. A group’s territory can span 10 to 30 km around, but massive outbreaks of 300 to 1,000 occur rarely and do not indicate orc strength, but rather external weakness, such as human military failures. The last recognized event of this kind happened 15 years ago in Wales, when a colleague interested in the dark elves’ reproductive cycle witnessed a war against a horde estimated at 1,100 individuals, which ultimately provoked the mobilization of Welsh forces.

  As for their culture, orcs do not possess a narrative history like ours. Instead, they maintain a hierarchical memory where what matters is not the past, but who dominates now. Their core values are observable strength, damage resistance, territorial possession, and proximity to the alpha. They do not value wealth or abstract knowledge, and status is measured by strength. They fight among themselves, with sub-lieutenants and followers; the sub-lieutenants are slightly taller but not as much as an alpha—something I observed in an improvised camp where betas beat each other to rise in the hierarchy, a practice that left me perplexed by its rawness.

  They do not colonize through agriculture or resources, but through reproductive pressure: a territory is valid only if it can be defended, house incubators and enslaved women, and have nearby prey. If it fails in that, they migrate driven by internal conflicts—as I saw in a massive migration that lasted weeks and razed border villages during my second year of study with imperial explorers. This prompted the Emperor to fund my research, and I am grateful for the facilities provided by the imperial guard and Commander Joffrey’s talents in avoiding killing as many as possible so we could study the greatest number of orcs.

  Parasitic reproduction is obligatory and only the alpha implants: the process involves capturing a host, glandular infection, mental maternal reconfiguration of the host, incubation, and multiple births. Each viable host produces several litters, and the betas protect the incubator as a critical resource—not out of empathy, but for group stability. I didn’t know this until we rescued a human incubator during a night raid, and her altered mind wanted to return to copulate with the orcs—she was lost and corrupted, a horror that haunted me for months. Psychologically, the orc does not seek war out of hatred, but for social equilibrium: without an external enemy, they fight among themselves until death or division, making external war their natural mechanism for population regulation.

  Strategically, a small unit represents a minor local threat—they dedicate themselves to hunting large animals, seeking prey, or killing each other for dominance—while a horde is a regional collapse event. Most historical hordes arose after noble disputes, abandoned borders, or insufficient garrisons, and they never appear in vigilant states. In conclusion, as a naturalist who has spent three years hunting and studying these creatures with adventurers and military forces, I can affirm that the orc does not conquer strong kingdoms, but grows due to the incompetence of weak kingdoms or lords who ignore internal problems. Their expansion is not a deliberate invasion, but an ecological replacement: when human authority fragments, orc groups appear and, without control, can grow. Therefore, I exhort nobles and any military officer not to neglect their duty to the Emperor and to eliminate any of these vermin.

  In my field notes, few scenes have left me as marked as the discovery of the incubator in the orc camp in the Black Iron Forest during that harsh winter of year 14 of Valerian III’s reign. We had followed the trail of a unit of seventy or more individuals for weeks, guided by distant echoes of screams and dried blood stains marking the trunks as claimed territory. When we burst in at dawn—I, Garrick the Red, two veteran swordsmen, and a cleric of the Order of the Eternal Flame—the alpha had already been felled by a lucky blow from Garrick, and the succession frenzy was exploding around us: betas tearing each other apart with grunts and blows that shook the ground.

  Amid the chaos we found the incubator. It was Lirien of Vaelor, missing five months earlier after the sacking of a caravan. Her belly was grotesquely swollen from the third litter in progress, the skin taut and veined with dark lines, her entire body trembling as if in perpetual fever. We freed her from the braided tendon restraints that held her to a post, and the cleric attempted a basic purification rite, but she did not react like a rescued prisoner. She did not cry for help. She did not weep. Instead, when Garrick approached to help her stand, she stared fixedly at him—eyes dilated, almost black—and murmured in a hoarse, halting voice: “I love him… my love…” Then, with a slowness that froze the blood, she extended a hand toward the decapitated orc corpse, trying to touch it between the legs while her lips curved into an absent smile. “I can still smell him… I still want him inside. I need him to fill me again.”

  It wasn’t just madness. It was something deeper, more primitive. Her mind—or what remained of it—had been completely rewritten. Note 1

  But what we did understand was that her will was no longer her own. Her will had been reduced to a single thing: to copulate with the alpha. It was not human desire, not common lust. It was an absolute compulsion, a hunger that erased everything else. When we tried to drag her away from the corpse, she resisted with a strength that did not match her weakened state: she scratched, bit, screamed that “without him I am nothing,” that “the young need him inside,” that “the emptiness burns me if I don’t have him.” Garrick, who had seen everything in twenty years of campaigns, paled and muttered a low curse. The cleric only sighed—it was not the first time. We had arrived too late.

  We tried to reason with her, to explain that the orc had destroyed her, that it was slowly killing her. She only looked at us as if we spoke another language. “He doesn’t destroy me… he completes me. Every time he takes me, I become more. The young make me strong.” Her voice broke into moans when she spoke of how the alpha mounted her, how he filled her until she couldn’t breathe, how every thrust gave her a purpose that nothing else in the world could provide. It was as if her brain had forgotten how to think of freedom, family, home; only the instinct to be taken, to be used, to be the perfect vessel for the alpha’s seed remained. We tried to take her by force, but every step we took away from the camp made her writhe more, screaming that “the emptiness was killing her,” that she needed to go back.

  In the end, there was no other choice. Garrick made the decision none of us wanted to make: we let her go. We let her run back toward the smoldering remains of the camp, where the surviving betas were already fighting for dominance over the corpse. We watched her disappear among the trees, staggering, hands pressed to her belly as if to comfort—or arouse—what she carried inside, murmuring obscene promises to the air. We never knew how long she lasted afterward. Records from previous expeditions indicate that a parasitized woman survives two to three months before her body collapses: successive litters—five or six young per cycle, with barely weeks between births—shred everything inside. The uterus tears, the pelvic bones splinter, blood pools internally until the organs fail one by one. But before physical death comes the death of the mind: it fragments into an eternal longing for the alpha, for being fucked, for being filled, for being useful. The emptiness left by his absence is worse than any pain.

  1: I recall the studies on dead women examined by physicians who noted brain changes. The most intelligent, Aureliano the Magnificent—the greatest doctor who transformed the medical structure of our empire and half of Europe—described the process as a change in cerebral synapses and modification in dopamine pleasure configurations. His greatest legacy is alchemical research for medicines, vaccines, and hygiene, as well as being the first to raise a cry to the heavens when the empress drank beer; he prohibited alcohol consumption for pregnant women, as well as tobacco. There was resistance, but he is the greatest physician of our empire.

  Personal Diary of His Excellency Don Rodrigo de Silva y Guzmán, Duke of Medina Sidonia, Royal Linguist of the Unified Crown of Hispania and Extraordinary Emissary of His Imperial Majesty to the Court of the Shahanshah Palace of the Thousand Columns, Isfahan, Persia Day 58 of the Diplomatic Mission Caravan of the Great Western Desert, two days’ journey from the City of the Sand Towers

  The sun falls like molten lead on the dunes. The wind carries the smell of camel, scorched leather, and something else: the acrid scent of hot iron and the sweat of beasts that are not entirely beasts.

  I sit in my palanquin, curtains parted barely a finger’s width, pretending to study my parchments. But my eyes never leave the Persian guards flanking the caravan. They call them Uruk-hai—without doubt an elegant name for the Persians.

  They are not like the green, savage orcs of the European Marches I knew in my youth: those brutes with filthy emerald skin, crooked fangs, and brains the size of a walnut, who howled and beat their chests before charging like animals. These… these are something else.

  Skin black as polished obsidian or forged iron gray at dusk. Yellow eyes that glow. Humanoid bodies, yes—two arms, two legs, upright torso—but the differences are brutal: pointed ears pierced with bronze rings, lower fangs that protrude even when the mouth is closed, thick-fingered hands tipped with black claws like talons. They stand nearly two varas tall and move with a discipline that chills my blood.

  I saw them this morning at dawn as we broke camp. Four of them forged a replacement crossbow in less than half an hour from parts they carried in their saddlebags: screws, springs, desert ebony wood. They did not improvise. They discussed in their language—quick, sharp, precise.

  And that is where my terror turns to study.

  Their language—Uruk-khaz—is military in every syllable. Direct. Without flourishes. Without useless genders, without superfluous verb tenses. One verb for “attack now,” another for “defend and retreat in order,” another for “kill without making noise.” I have been transcribing it secretly these weeks. They, in turn, study our language.

  I hear their command cries: —Graz! Kh?l-dar!—and I know, from the tone and gesture, that it means “Wedge formation, shields high!” It is not animal croaking. They are words.

  And they also master Persian with a guttural but perfect accent when addressing me. One of them—the sergeant with a braided beard adorned with silver rings—greeted me yesterday: “Good day, Excellency. The road is safe.” He pronounced each syllable with an elegant, fluid touch.

  They are intelligent. Civilized. Mercenaries who are paid in gold and slaves, but who could rule kingdoms if they wished. And that, my God, is what terrifies me. Because orcs should not be like this. They should be the savage threat that justifies our walls and our prayers. These… these are proof that barbarism can learn, organize, and surpass us.

  I think of my wife, the Duchess Catalina de la Vega. Beautiful, yes. Of impeccable blood. Married by duty on a day of alcohol and politics, when my father and hers negotiated our marriage over an oak table and two glasses of malvasia. She has never looked at me the way she looks at the mirrors of the court. She is interested in rumors, alliances, the power woven in the salons of Toledo. To her, I am a title with legs. A duke who speaks dead and living languages, useful in imperial audiences, bothersome in bed.

  And then I think of her.

  The redhead. The slave I bought in the Damascus market before departing, because her green eyes pierced me like a Moorish dagger. Her name is Aisha in her tongue, but I call her Fire when we are alone. She dances the belly dance as if the desert itself taught her: hips moving like waves of sand, pale skin dotted with freckles like stars, red hair falling to her waist like spilled blood. When she leans toward me, the scent of myrrh and sweet sweat clouds my judgment.

  Last night, in the tent, while the Uruk-hai stood guard outside, she danced only for me. Naked except for the silver bells on her ankles. Every turn was a promise. Every glance, an oath my wife has never made.

  Marrying for duty is a stupidity of kings and nobles. A day of business among nobles and they chain you for life to a woman who prefers the throne to the bed. While I… I burn for a slave who calls me “my lord” in a husky voice and then, when no one is looking, calls me “my duke” and bites my neck.

  Forgive me, Lord. I digress again.

  The Uruk-hai have just given the order to march. Their sergeant looked directly at me. Yellow eyes. A smile that does not reach the fangs. He said, in perfect Castilian:

  “Excellency, the wind is changing. We must advance before the sandstorm catches us.”

  I nodded. I closed the curtains.

  And now I write these lines with a trembling hand, while the caravan sets in motion and the camels’ hooves sound like war drums.

  I fear these orcs more than any European army. Because they are not beasts. They are something worse.

  And meanwhile, in my chest beats another sweeter, more shameful fear: the fear of returning to Hispania, to my courtly wife and my life of duty… when all I desire is to remain in this desert, with my redhead dancing under the moon and forgetting I was ever a duke.

  May the Olympian gods protect us. Don Rodrigo de Silva y Guzmán

  Treatise on the Noble Race of the Desert Uruk-hai Compiled by Abu al-Fadl ibn al-Hakim al-Isfahani Royal Scholar of the Imperial Academy of the Thousand Columns in the service of His Majesty the Shahanshah, Light of the World and Shadow of God on Earth

  In the name of the Sun King and Moon Queen who forged fire and steel, and placed each people in its place according to their design.

  I have devoted thirty-seven years to the study of the races inhabiting the fringes of the Empire. None has awakened in me greater admiration—and, I confess with humility, greater reverential fear—than the Uruk-hai, the Sons of the Black Wind, whom the barbarians of the distant West contemptuously call “desert orcs.”

  I call them, with the respect they deserve, the Guardians of the Eternal Dunes.

  Physical Analysis The Uruk-hai is a masterpiece of adaptation to the wasteland. Their height ranges from two and a half to three varas (1.90 m to 2.30 m), with dense, fibrous musculature and no superfluous fat. Their skin, obsidian or steel-gray, absorbs daytime heat and releases it at night, allowing them to march at high noon where a man would perish.

  Their golden-yellow eyes have vertical feline pupils: they see in blinding light and absolute darkness.

  The lower fangs are permanent natural weapons.

  Mobile ears detect prey at fifty paces.

  Horny hands skin without a knife.

  Their forward-leaning posture favors continuous charge with shield and spear.

  They are not made for comfort. They are made to advance.

  Biological Analysis Long-lived: they frequently exceed one hundred twenty years.

  Efficient metabolism: they survive ten days on dried meat and brackish water.

  Pathological resistance: I have seen them drink corrupted water without fever.

  Their blood clots quickly. They rarely die from bleeding out.

  They have no females of their own; they use slave women to procreate.

  The young are born with visible fangs and walk before six months.

  I have observed a notable phenomenon: in times of peace their birth rate declines. As if war were their natural reproductive season.

  Cultural Analysis They are not savages. They are martial.

  Each clan is governed by a Khan chosen by merit.

  Their code—Khazad?r—states that betraying a contract is worse than death.

  They worship Graz’Th?l, Lord of Storm and Forge.

  Their temples: circles of black monoliths in the middle of nowhere.

  They recite epic poetry with lizard-skin drums.

  They love steel. Rigorous merchants.

  They accept slaves as war payment, never among themselves.

  The Slave Women and Captives The desert teaches efficiency.

  Captives are not destroyed uselessly. After one or two moons of adaptation, many develop intense devotion to the tribe. It does not arise solely from fear: it arises from belonging.

  Some rise to legitimate companions and fight alongside the clan. I have seen a Frankish woman behead three enemies with a curved khazad while praising the storm god.

  Among them exists the secret language Uruk-s?l, the tongue of submission: S?l-thrak — slave my lord Graz-s?la — I serve from the heart Kh?l-nara — I obey in silence A language learned at night, not taught.

  Linguistic Analysis Uruk-khaz is a perfect military language: without articles, without genders, without excess.

  Every word is a compressed order.

  Yet they can recite elegies for hours without repetition.

  They learn new languages in less than three moons if it serves war.

  Martial Analysis They do not learn to fight. They remember how to do it.

  Every combat modifies their technique. There is no universal defense against them.

  They form phalanxes, use repeating crossbows, khazad swords, sandstorms as cover.

  They march fifty miles and fight without rest.

  Five hundred defeated ten thousand ghouls before my eyes.

  A cry from their Khan halted a full charge.

  Demographic and Tribal Dimension Analysis Many foreign generals have erred in measuring Uruk-hai strength by their numbers. Such judgment reveals ignorance, for in the desert quantity is weakness and scarcity is power.

  An ordinary Uruk-hai tribe consists of thirty to one hundred individuals. This is not demographic poverty, but perfect adaptation.

  The desert permits no excess: each warrior requires water, meat, and hunting territory; beyond a certain point, survival itself forces the tribe to divide or kill each other. And the Uruk-hai, faithful to their nature, choose both.

  Among them, ritual violence is not disorder, but regulation. Challenges for hierarchy, disputes over prestige, and trials of strength eliminate the weak and prevent overpopulation. This is compounded by permanent wars against other tribes, wasteland predators, black sandstorms, and cyclical famines. Thus the tribe remains small not from inability to grow, but because the environment destroys any excess.

  In exceptional cases, a Khan of extraordinary will emerges, capable of unifying several clans without fragmentation. Then larger tribes appear, from two hundred to eight hundred members. Such groupings disrupt imperial trade routes and force garrisons to fortify wells for entire seasons.

  However, the annals of the Empire record a unique and fearsome fact.

  Approximately two centuries ago, a great confederation emerged under a single banner. Five thousand Uruk-hai marched united. They did not migrate: they declared war.

  For ten years they fought against human kingdoms. They did not act as a savage horde, but as an organized army: they besieged cities, sabotaged oases, exterminated caravans, and repeatedly defeated regular forces in open field. Human victory was possible only through coalition of different desert tribes, deep stone fortifications, and massive use of heavy archery.

  Even defeated, they were not exterminated; they dissolved again into smaller tribes, like sand carried by the wind.

  Conclusion The Uruk-hai are not monsters. They are the final form of the warrior.

  That the Shahanshah employs them as mercenaries demonstrates wisdom: he who has the Sons of the Black Wind at his side has the desert itself fighting for him.

  Abu al-Fadl ibn al-Hakim al-Isfahani May my pen always be worthy of the truth.
