Tech-Priest Construction This article, Aigéad Fuil, is currently under active construction. The author, TechCaptain, apologizes for the inconvenience.



"If you're not immediately killed by a massive spider, you could be attacked by an air-borne jelly-fish or eaten from the inside out by fungus shot into you by a massive mushroom stalk, that's assuming you don't get dissolved by acid or choke to death by a failed breathing aparatus. And that also assumes the barbarious natives don't kill you in a fight over resourses. But them marines and some of the others pay well."

On the former Ice Hive World, now turned Volcanic Death World of Aigéad Fuil, a single settlement, protected by void shields exists on this world, has a burgeoning society of techno-barbaric gangs. They are allowed to commit their gang warfare in the trade city as long as they don't attack off-worlders and give a tithe to the Astartes overlords. The Techno-Barbarians use armored vehicles, and scavenge from failed recon teams and aircraft from the wastelands due to the acidic atmosphere. But the risks of these expeditions and the rapidly degrading hulls of the vehicles cause inter-gang warfare, as gangs fight for loot and intact hulls for their own craft.The hardened youth, with an experience of armored warfare and technological expertise are perfect candidates for the Astartes. The ancient hives that eked out a harsh living on the acid-rain soaked planet of Aigéad Fuil was brought into the Imperial Fold, and would be gifted to the Bloodmoon Hunters Chapter for overseeing the warp routes further into the Ishtar Fringes that would become known as the Sanguis Portus, or the "Blood Gate". Few others make life out of heavily processed ancient lower hives of hives whose void shields has failed over time.

With hostile atmosphere and frequent tectonic shifts, the survivors to take particular care about their airtight environment, oxygen rationing, geothermal energy and the fragility of the tectonic plates. They are hardy folks, who use a lot of breathing suits, have great knowledge of mineralogy and technically competent on a level of your standard Forge worlders. The need for everyone to know how to replace air-filters. The great subterranean hive and former great subterranean hives of Aigéad Fuil are a reverse of a typical hive. The lowest reaches of the hives are the safest where the techno-barbarians have some organization and security but the upper hives where scavengers prey is where the lawless infest to get the limited supplies from the only working space port.

The space port is protected by ancient void shields but further was rebuilt out of specially made glass as the only material that could survive long term in Sulfuric acid. But this has meant that the connection to outside the planet is extremely fragile. Any ships that deliver supplies or pick up cargo have to go through special precautions lest they destroy the port or have their hulls fail and crash in the wastelands.

Biosphere[]

"From the fungal tapestry that blankets the land to the elusive dance of Léim Portán, life on Aigéad Fuil is a symphony of adaptation. Thorns are blades, and the air itself holds the whispers of danger. Each creature, a survivor's tale etched in venom and resilience, weaves the epic of this harsh, unforgiving realm."
—Anonymous

Sulfuric acid is produced in the upper atmosphere of Aigéad Fuil by the Sun's photochemical action on carbon dioxide, sulfur dioxide, and water vapor. Ultraviolet photons of wavelengths less than 169 nm can photodissociate carbon dioxide into carbon monoxide and atomic oxygen. Atomic oxygen is highly reactive. When it reacts with sulfur dioxide, a trace component of the Aigéad Fuilian atmosphere, the result is sulfur trioxide, which can combine with water vapor, another trace component of Aigéad Fuil's atmosphere, to yield sulfuric acid. In the upper, cooler portions of Aigéad Fuil's atmosphere, sulfuric acid exists as a liquid, and thick sulfuric acid clouds completely obscure the planet's surface when viewed from above. The main cloud layer extends from 45–70 km above the planet's surface, with thinner hazes extending as low as 30 km and as high as 90 km above the surface. The permanent Aigéad Fuilian clouds produce a concentrated acid rain, as the clouds in the atmosphere of Earth produce water rain.

The atmosphere exhibits a sulfuric acid cycle. As sulfuric acid rain droplets fall down through the hotter layers of the atmosphere's temperature gradient, they are heated up and release water vapor, becoming more and more concentrated. When they reach temperatures above 300 °C, sulfuric acid begins to decompose into sulfur trioxide and water, both in the gas phase. Sulfur trioxide is highly reactive and dissociates into sulfur dioxide and atomic oxygen, which oxidizes traces of carbon monoxide to form carbon dioxide. Sulfur dioxide and water vapor rise on convection currents from the mid-level atmospheric layers to higher altitudes, where they will be transformed again into sulfuric acid, and the cycle repeats.

Sulfuric acid is formed naturally by the oxidation of sulfide minerals, such as iron sulfide. The resulting water can be highly acidic and is called acid mine drainage or acid rock drainage. This acidic water is capable of dissolving metals present in sulfide ores, which results in brightly colored, toxic streams. The oxidation of pyrite (iron sulfide) by molecular oxygen produces iron.

History[]

"A frozen cradle shattered in the fires of betrayal, Aigéad Fuil bears scars of a war forgotten. Ultramarine wrath collided with the Death Guard's legacy, reshaping the icy bastion into a volcanic purgatory. Bloodmoon Hunters emerged from the ashes, custodians of a history lost in the echoes of the Sanguis Portus."
—Anonymous

During the time before the Horus Heresy, Aigéad Fuil was a Icy Hive World where the air was sulfuric and an outpost of the Death Guard Legion. Here they stored great many munitions for the wars to be conducted on the Imperium's behalf. The Ultramarines sent a fleet to exterminate the planet to deny the enemy their munition stocks. Upon arriving to Aigéad Fuil, the Ultramarines committed to Exterminatus via Tectonic bombing. The Tectonic bombing was aimed at dormant Super Volcanoes across the planet. The extreme heat and gases expelled by the super volcanoes would cause a planet extinction event similar to what ended dinosaurs on Earth.

During the Exterminatus of the planet, the Pharos gets activated and the Ultramarines make way for Macagge at fastest possible speed, missing the fact a few Hives survived. The eruptions destroyed most of the hives and left the world in a almost terminally volcanic active state. Only a few hives urvive by have beem position in the far reaches of Aigéad Fuil where it was still cooler. Throughout the Heresy records of this incident and even of the world of Aigéad Fuil get destroyed. This left this world lost along with the worlds beyond the Sanguis Portus. For the next several thousand years this world was forgotten by time.

Next when the Imperium rediscovered the Damuterr System, the world of Aigéad Fuil was a much harsher world with Tectonic instability and acidic atmosphere. The surviving hives had to be brought into compliance. This action was done by the newly founded Bloodmoon Hunters Chapter in M35. During the Compliance Action tragedy struck when containment on one of the vaults of the Death Guard was broken causing a mutagenic outbreak. In response the entire chapter was called to deal with the fighting. Over the course of fighting the mutagen infected Hive the Command and veterans of the Bloodmoon Hunters were falling in droves. In a desperate act to contain the threat Artificer Folsom deactivated the Void Shields of the Hive. The Acid of Aigéad Fuil destroyed all who had remained in the Hive.

The rest of the War of compliance was directed at the senior most person left, Artificer Folsom. Through use of ambush tactics and small unit fighting in the great tunnel systems, he claimed the world for the Bloodmoon Hunters.

Fortress-Monastery[]

Lebenmali Forge

Lebenmali Concept

"Folsom's Keep, a citadel hewn from the bones of a world, stands resilient against the acid storms, a crucible of aspirants and a shrine to the fallen. Above, Lebenmali, a celestial sentinel, watches over the Warp Corridors. Aigéad Fuil, both training ground and sanctuary, where the chapter's legacy is forged in fire and tempered in blood."
—Anonymous

The Fortress-Monastery of the Bloodmoon Hunters is actually split in two. On the surface of Aigéad Fuil under heavy void shields is the Citadel known as Folsom's Keep. At Folsom's Keep Aspirants are gathered once they have made it through the trials for their initial training and indoctrination. Floating in orbit above is Lebenmali, a grand Star Fort designed specifically for the Bloodmoon Hunters and their mission to watch over the Warp Corridors of Sanguis Portus.

Lebenmali is essentially a mobile battle station. In form and scale, it is nearer a planetoid than a conventional vessel; it is a mighty cathedral of war that dwarfs the largest Battle Barge, and wields the firepower of a formidable fleet. The size of a large asteroid, its foredeck can dock a dozen Imperial Navy Cruisers around its circumference. The hull of the star fort is many kilometres long, triangular in cross-section with its upper surface bristling with weapons and sensorium domes. Every surface was clad in solid armour plating and every angle was covered by more torpedo tubes and Lance batteries than any Imperial Battleship could muster. Countless smaller spacecraft, repair craft and unmanned scouts orbited like supplicants jostling for attention, and the wake of the titanic engines seemed to churn the void itself with the force of their plasma fire. Its sides are studded with the maws of Macrocannons, missile clusters, Thunderhawk launch bays, and Plasma Mortars, while the spires that rise from its surface are serrated with hundreds of Defense Laser cupolas.

Folsom's Keep[]

Folsom's Keep

Folsom's Keep Concept

Folsom's Keep is the Bloodmoon Hunter's Citadel for training and indoctrination. On the opposite side of the planet of the remaining hive of Aigéad Fuil sits this mighty fortress protected by several layers of ground as well as the heaviest void shields the Imperium could produce. Small to be considered a true Fortress-Monastary but still large enough to have the training grounds for the various methods of combat that the Bloodmoon Hunters engage in. In the outer tunnel structures, the Bloodmoon Hunters allow the natural Flora and Fauna flourish as a first layer of defense and as a challenge to all Aspirants. Getting through the Damhán Alla traps as well as colonies of Aiteann Péisteanna is no easy feat even for an Astartes in full armor much less the humans who test themselves to become true Hunters.

This sombre keep serves as a shrine to the memory of fallen Bloodmoon Hunters who battled the Chapter's gravest foes. Whenever an Aspirant undergoes his ordeal of initiation, he must first make a pilgrimage to this mighty edifice and call upon the spirits thy lie within. A place of pilgrimage to test the endurance of the faithful and to serve as a memorial to unwavering devotion to the Emperor.

Flora & Fauna[]

"In the crucible of Aigéad Fuil, survival is the dance of the vigilant. Every step, a gamble. Adapt or perish, for the very air holds the whispers of danger. In this relentless realm, the wise tread lightly, the bold endure, and the unprepared become prey to the thorns, fangs, and acid-laden tendrils that define this volatile world."
—Anonymous

Fungi[]

"Amidst the fungal tapestry that blankets the land, silent hunters stalk the deceiving blooms. Fungi, mistaken for flowers, conceal their true nature. Some grow thorns to spread their seed through unwitting travelers, while others launch poison-laden projectiles, turning the hunter into the hunted. In this deadly ballet, tread cautiously, for not all blooms are as innocent as they appear."
—Anonymous

The plant-like organisms on this planet are mostly many types of fungi. Flowers are almost non-existent, which is hard to tell, as many fungi species can be confused for flowers due to their shapes and colors, especially when looked at from a distance. But not all fungi species are small and colorful, some can reach incredible sizes.

Many organisms use the common tricks to prevent being eaten, like tasting bad, being poisonous or by growing thorns. But there are some species which has taken thorns to the next level. They can generally be divided into two groups. The first uses its thorns to spread itself to other areas, because inside those thorns, which get stuck in animals, are seeds, ready to be taken grow within the animal becoming food for the Fungi. The second group uses the thorns purely for defense and is capable of using them as projectiles. If an animal eats too much of this species, it will bombarded the animal with thorns that are filled with poison.

Géag Aigeach[]

"Beware the acid rain, a symphony of dissolution. Géag Aigeach, a sinister gardener, showers death from above. Its tendrils, both sower and reaper, create safe sites in the aftermath. Natives navigate this acidic ballet, where rainfall is not life-giving but a prelude to an insidious dance with the devouring flora."
—Anonymous

A highly acidic liquid drops onto the ground below the plant. This liquid dissolves any other living organisms in the spot where it lands and also breaks down rocks and other large particles into a nutrient-rich seed bed. When seeds mature and drop from the flower, they land in this "safe site" and germinate readily under the protection of the parent plant. This highly evolved form of "parenting" has rarely been observed in plants. The plant consists of one central stem with two tendril like appendages; each of these three sections has a red bud hidden within the leaves. It is from the bud that the toxic spores are ejected.

Smugairle Aigéad[]

"In the skies, the Smugairle Aigéad, free-swimming specters, weave through the acidic breeze. Their umbrella-shaped bells conceal the sting of concentrated sulfuric acid. To hunt or be hunted, a dance in the air where the medusa's pulsating rhythm heralds danger. In this ethereal waltz, natives engage elusive foes in a celestial battle of life and death."
—Anonymous

The Smugairle Aigéad concentrates sulfuric acid in cell vacuoles. The primary function of the accumulated acid in the Smugairle Aigéad's life history is unknown.It is thought to provide an important ecological defense.

Smugairle Concept

Smugairle Aigéad Concept

The Smugairle Aigéad mainly free-swimming/flying atmosphere animals with umbrella-shaped bells and trailing tentacles, although a few are not mobile, being anchored to the ground by stalks. The bell can pulsate to provide propulsion and highly efficient locomotion. The tentacles are armed with stinging cells and may be used to capture prey and defend against predators. Smugairle Aigéad have a complex life cycle; the medusa is normally the sexual phase, the planula larva can disperse widely and is followed by a sedentary polyp phase.

The main feature of a Smugairle Aigéad is the umbrella-shaped bell. This is a hollow structure consisting of a mass of transparent jelly-like matter known as mesoglea, which forms the hydrostatic skeleton of the animal. 95% or more of the mesogloea (the tissue that functions as a hydro-static skeleton) consists of Concentrated Sulfuric Acid, but it also contains collagen and other fibrous proteins, as well as wandering amoebocytes which can engulf debris and bacteria. The mesogloea is bordered by the epidermis on the outside and the gastrodermis on the inside. The edge of the bell is often divided into rounded lobes known as lappets, which allow the bell to flex. In the gaps or niches between the lappets are dangling rudimentary sense organs known as rhopalia, and the margin of the bell often bears tentacles.

Aiteann Péisteanna[]

"Beneath the surface, segmented hunters await. Aiteann Péisteanna, agile and voracious, use sulfuric acid mucus to navigate the subterranean labyrinth. Their predatory ballet, a leap to the unsuspecting, a burrowed dance through the soil. In this realm of darkness, natives confront the writhing serpents, turning the tables on creatures that feed from within."
—Anonymous

Each body segment has a pair of fleshy protrusions called parapodia that bear many bristles, called chaetae, which are made of chitin. Aiteann Péisteanna are segmented worms, generally less than 10 cm (4 in) in length, although ranging at the extremes from 1 mm (0.04 in) to 3 m (10 ft). They can sometimes be brightly coloured, and may be iridescent or even luminescent. Each segment bears a pair of paddle-like and highly vascularized parapodia, which are used for movement and, in many species, act as the worm's primary respiratory surfaces. Bundles of bristles, called setae, project from the parapodia.

Aiteann

A Colony of Aiteann Péisteanna

However, Aiteann Péisteanna vary widely from this generalised pattern, and can display a range of different body forms. The most generalised polychaetes are those that crawl along the bottom, but others have adapted to many different ecological niches, including burrowing, swimming, pelagic life, tube-dwelling or boring, commensalism, and parasitism, requiring various modifications to their body structures.

The head, or prostomium, is relatively well developed, compared with other annelids. It projects forward over the mouth, which therefore lies on the animal's underside. The head normally includes two to four pair of eyes, although some species are blind. These are typically fairly simple structures, capable of distinguishing only light and dark, although some species have large eyes with lenses that may be capable of more sophisticated vision.

The head also includes a pair of antennae, tentacle-like palps, and a pair of pits lined with cilia, known as "nuchal organs". These latter appear to be chemoreceptors, and help the worm to seek out food. Once finding food colonies of the Aiteann Péisteanna would leap or make way to the food source using Sulfuric Acid mucus to break down a creature for them to feed. Generally it will burrow inside a creature and eat from the inside out.

Damhán Alla[]

"In the shadows of the burrows, Damhán Alla, silent architects, construct trap-doors to the abyss. Their daggerlike chelicerae and venomous strategies make them nocturnal specters. In the moonlit theater, natives face the elusive, their web of deceit countered with calculated strikes. A dance with the unseen, where the predator becomes the prey."
—Anonymous

Damhán Alla are tube-dwelling spiders that construct rudimentary trap-doors. They spend most of their time here and are rarely seen above ground. The medium to large spiders range from five to fifteen feet long. They are characterized by their downward pointing, daggerlike chelicerae, and the segmented series of plates on the upper surface of the abdomen. The carapace is mostly flat, though it can be slightly elevated near the head. The eyes are distinctly clustered together on a single nodule. Anterior median eyes are small, but posterior median eyes are large and round. The lateral eyes are long and kidney-shaped. The distal leg segments have strong spines and three claws. Chelicerae are vertically attached to the cephalothorax. In the past, they were frequently believed to lack venom, but it was shown that at least some Damhán Alla species have venom glands.

Damhán Alla

Damhán Alla Concept

They are active at night and live for many years. Although most species live in burrows, cave-dwelling species also fasten their retreats to the cave walls. Both burrows and retreats are sealed with woven doors. Trapdoor nests are generally built in shady areas with moss or sparse vegetation. Some make silk trip-lines radiating away from the burrow entrance. Adult males sometimes wander in search for females, but females rarely leave their burrows. The respiratory system consists only of book lungs, which could help explain why they are relatively inactive.

Léim Portán[]

"On the ground, the Léim Portán, masters of mimicry, wait in ambush. Their silk-woven illusions conceal deadly intent. Natives traverse the terrain, where these hunters become the hunted. A dance of disguise and revelation, a test of instinct and strategy in the tangled embrace of deceitful webs."
—Anonymous

Léim Portán do not build webs to trap prey, though all of them produce silk for drop lines and sundry reproductive purposes; some are wandering hunters and the most widely known are ambush predators. Some species sit on or beside Fungi, where they grab visiting creatures. Individuals of some species are able to change color over a period of some days, to match their surroundins on which they are sitting. Some species frequent promising positions where they await prey, and some of them sit in the open, where they are startlingly good mimics. The medium to large spiders range from eight to twenty-five centimeters long.

Léim Portán

Léim Portán Concept

Other species of Léim Portán with flattened bodies either hunt in the crevices or shelter under such crevices by day, and come out at night to hunt. In each case, Léim Portán use their powerful front legs to grab and hold on to prey while paralysing it with a venomous bite. Some Léim Portán hunt other creatures in ways that seem intelligent, outflanking their victims or luring them from their webs. Laboratory studies show that Léim Portán's instinctive tactics are only starting points for a trial-and-error approach from which these spiders learn very quickly how to overcome new prey species.

Spúinse[]

Clinging with root-like “rhizoids” to the soft, muddy sediment, the Spúinse captures prey that pass by its branches. Typically, Spúinse feed by straining bacteria and bits of organic material Sulfuric Oxide air they filter through their bodies. However, carnivorous Spúinse snare their preywith barbed hooks that cover the Spúinse’s branching limbs. Once the Spúinse has its prey in its clutches, it envelops the animal in a thin membrane, and then slowly begins to digest it.

Salachar Luíochán[]

"From the depths, the Salachar Luíochán, colossal ambush predators, erupt in pursuit. Their acid-coated spines and subterranean siege make them formidable foes. Natives face the behemoth, turning the underground labyrinth into a battleground. In this hunt of giants, survival demands strategic cunning and the resilience to face the terror that emerges from the very ground beneath."
—Anonymous

Salachar Luíochán are depicted as subterranean animals with long, serpentine bodies. Some of the species have been measure up to 30 feet long, and 6 feet across at its widest point, and may weigh 10-20 tons. Their heads consist of a massive, black, armored beak, which is used to push aside the dirt whilst digging. The beak opens up like a grotesque flower; it consists of a wide upper jaw, a thinner lower jaw, and a pair of hooked mandibles on either side, they measure three feet long. Salachar Luíochán are ambush predators, preferring to sneak up on their quarry, though they are shown to chase it down with great determination. Erupting from the ground and using tentacles to ensnare prey, pulling them into their mouth. The tentacles wrap around the prey, biting into its flesh or hooking the prey with their horn-like spikes. This species is able to tunnel through rock by releasing formic acid from its mouth to soften rock before using its magnesium mandibles to eat through it. As well as having Acid coated spines along it's segmented exoskeleton, the Salachar Luíochán travel underground using these modes in hunt of prey to ambush. Sometimes when needed spitting acid onto it's prey to speed up the breakdown process

Other Minor Flora and Fauna[]

Faolán Aer-Méitháin: These Gargoyle looking aerial creatures have evolved bat-like wings, allowing them to live high above the acidic clouds. They have gas-filled bladders that allow them to float, and they feed on the sulfuric compounds in the atmosphere. Their bodies are covered in natural gas masks that filter out toxins. Their natural gas masks conceal razor-sharp teeth, and they hunt by swooping down to snatch prey with precision.

Carraig-Dealaithe: Stout, quadrupedal creatures with sturdy limbs and powerful jaws for grinding stone. These ground-dwelling creatures use their strong jaws to grind up stone and excrete it as a form of exoskeletal armor. They are herbivores that travel in herds and rely on their armor for protection against predators. Despite their herbivorous diet, their strong jaws can crush rocks, making them formidable defenders against predators.

Eilitheoir Uiscebhaile: These long, serpentine creatures dwell in the few rivers that haven't been completely contaminated by the sulfuric acid rain. They have developed thick, acid-resistant scales and prey on smaller aquatic organisms that can survive in these extreme conditions.

Clochaí Teann: These creatures have adapted to live near the planet's volcanic regions. Their carapaces are heat-resistant and can withstand temperatures that would incinerate most other organisms. They scavenge for minerals and are a valuable source of sustenance for the inhabitants of Aigéad Fuil.

Fréamhaith Fiach: These parasitic vines are covered in tiny, venomous barbs. They wrap around the trunks of other fungal or plant species, injecting a corrosive toxin that slowly dissolves their host while providing sustenance for the vine. Intricate patterns and dark colors make them visually striking.

Lasrachaileann Fionnuar: In some of the planet's few bodies of water, unique strains of algae thrive. During the daylight hours, they photosynthesize and release oxygen, but as night falls, these algae produce volatile compounds that ignite upon contact with the acidic waters, creating eerie and beautiful displays of underwater "fireworks" attracting prey with the illusion of safety. The blooms become a hunting ground as unsuspecting organisms are drawn to the mesmerizing display.

Lusanna Fuilteach: These vibrant, trumpet-shaped flowers produce nectar rich in sulfuric acid, attracting only specialized pollinators capable of withstanding the acidity. Their bright colors stand out against the gloomy landscape.

Lileanna Sléibheoige: Found along the edges of the volcanic regions, lava lilies are heat-resistant flowers that thrive in the intense heat and toxic gases. They bloom with fiery, crimson petals and have adapted to draw sustenance from the planet's geothermal energy.
