A vaguely humanoid figure rises soundlessly from the black water, its algae-slick skin glistening beneath lanternlight. Moss hangs from its shoulders like drowned hair while pale reflective eyes stare without blinking. Its wide mouth twitches with strange clicking noises as murky water drips steadily from hooked teeth.

Brackish are amphibious swamp-dwellers native to the flooded waterways, drowned estuaries, and blackwater margins surrounding Ville des Marais and countless lesser marsh settlements. Though commonly mistaken for savage river predators by outsiders, Brackish society possesses ancient customs, territorial laws, and deeply ingrained flood rites tied to survival within unstable wetlands. They dwell within stilt-villages built atop submerged ruins, tangled mangrove roots, and slowly sinking wreckage reclaimed by moss, rot, and tidewater.

Their skin coloration varies depending upon region and water conditions. Some appear deep mud-brown with fungal growths along the spine, while others possess pale gray flesh marked by algae-green streaks beneath translucent skin. Hanging sensory tendrils around the jaw and throat twitch constantly in response to nearby vibrations, allowing Brackish to detect movement through water with unnerving accuracy. Many decorate themselves with shell jewelry, carved driftwood charms, polished riverbone fetishes, or salvaged trinkets recovered from drowned boats and flood victims.

Brackish settlements are partially living structures. Entire villages groan and sway gently with shifting currents, connected by rope bridges, floating platforms, and warped boardwalks slick with moss and fish oil. Territorial markers are subtle but unmistakable to those educated enough to recognize them - arrangements of reeds tied in symbolic knots, shell chimes hanging from dead trees, carved driftwood faces staring toward specific channels, or lanterns suspended above water at carefully measured heights. To ignore such signs is considered either profound ignorance or deliberate insult.

Though capable of trade and negotiation, Brackish remain deeply suspicious of drylanders. Most encounters begin with prolonged observation rather than open contact. Travelers often notice ripples beside their boats, pale eyes within reedbeds, or distant clicking sounds carried through fog long before a Brackish chooses to reveal itself directly. Their reputation for violence stems less from cruelty than territorial certainty. The swamp belongs to those capable of surviving it, and the Brackish have survived there far longer than most human settlements.

Combat

Brackish prefer ambushes and environmental warfare rather than direct confrontation. They strike from beneath dark water, hidden mudbanks, or hanging roots before retreating into terrain that favors their mobility and patience. A Brackish patrol often stalks prey for hours before attacking, studying movement patterns and weaknesses with unnerving discipline.

A Brackish commonly fights with hooked spears, harpoons, weighted nets, and crude river knives fashioned from sharpened shell or scavenged metal. They attempt to isolate enemies and drag wounded targets into deep water whenever possible.

Swamp Fever (Ex): A Brackish’s bite carries swamp-borne bacteria and mild venom. Any living creature damaged by a Brackish’s bite must succeed on a DC 11 Fortitude save or take 1 point of Constitution damage. One minute later, the victim must make a second DC 11 Fortitude save or become sickened for 1d4 rounds. The save DC is Constitution-based.

Marsh Ambush (Ex): A Brackish gains a +2 bonus on attack rolls against opponents denied their Dexterity bonus to AC while standing in swamp, shallow water, mud, or heavy marsh vegetation.

Amphibious (Ex): Although Brackish are aquatic, they can survive indefinitely on land.

Marsh Stride (Ex): Brackish ignore movement penalties caused by shallow water, mud, heavy reeds, and natural swamp terrain.

Slippery Hide (Ex): The oily mucus coating a Brackish’s skin grants a +4 racial bonus on Escape Artist checks and to resist grapple attempts.

Brackish settlements are frequently encountered near forgotten waterways and flood-prone districts where civilized authority weakens beneath humidity, isolation, and fear. Some fishing villages maintain cautious trade agreements with nearby tribes, exchanging lamp oil, preserved food, or metal tools for safe passage through dangerous marsh channels. Others simply vanish during flood season, leaving behind only drifting debris and strange carvings etched into cypress bark.

The relationship between Brackish and humanity remains deeply unstable. To fishermen and swamp laborers, Brackish are dangerous but understandable neighbors shaped by the same merciless wetlands governing everyone along the delta. To inland nobles and merchants, however, they are often regarded as living symbols of everything the swamp refuses to surrender to civilization’s ambitions.

Kelwyn’s Notes

I once traveled through a drowned reed territory under the guidance of Gibupgagool, who spent the better portion of two days warning me - with increasing irritation - not to mistake silence for absence. At the time I assumed he referred to predators. I later discovered he meant the Brackish themselves. One does not encounter them in the conventional sense. Rather, one slowly realizes they have been observing from the waterline for quite some time and simply had not yet decided whether acknowledgement was necessary.

The first Brackish village I witnessed appeared less constructed than accumulated. Walkways drifted slightly with the current. Lanterns swung from half-submerged pylons wrapped in moss and fishing cord. Entire structures leaned at angles that suggested imminent collapse, yet somehow endured with the stubborn balance unique to things built by people who understand water better than stone. Gib navigated the settlement with cautious respect, lowering his voice instinctively despite no visible threat presenting itself. It struck me then that the swamp teaches manners more effectively than civilization ever has.

Contrary to popular belief, the Brackish are not mindless marauders lurking in the reeds awaiting opportunities for murder. They are territorial, suspicious, and unquestionably dangerous, certainly, but no more inherently cruel than any other people shaped by generations of survival against hostile conditions. Their restraint simply manifests differently. Drylanders announce emotion loudly - through raised voices, threats, and theatrical outrage. The Brackish communicate through stillness. One learns very quickly that if a Brackish stops moving entirely, careful reconsideration of one’s recent decisions becomes advisable.

Gib later explained that many riverfolk quietly maintain informal agreements with nearby Brackish settlements whether noble authorities approve or not. Marsh channels change too frequently, floodwater hides too many dangers, and too many travelers vanish each season for practical cooperation to be ignored. Civilization often pretends it dominates the wetlands surrounding Ville des Marais. In truth, most settlements survive because older inhabitants occasionally permit them to.

There is a tendency among educated society to classify anything unfamiliar within the swamp as either monstrous or primitive. The Brackish fit neither category comfortably. They possess memory, ritual, territorial law, grief, humor, and community just as surely as humanity does. The difference lies primarily in perspective. Humanity views the marsh as hostile terrain to be endured. The Brackish view it as home. History suggests the swamp itself may agree with them.

Hallucinogenic Venom (Ex): Injury, Fortitude DC 12, initial and secondary effect identical. A creature failing its save experiences severe sensory distortion, emotional instability, and vivid hallucinations for 1d4 hours. While affected, the victim takes a -2 penalty on Wisdom-based checks and skill checks, cannot take 10 or take 20, and must succeed on a DC 13 Will save whenever exposed to stress (combat, loud sounds, sudden movement, taking damage, and similar circumstances) or become confused for 1 round, as the spell. This is a poison effect. The save DC is Constitution-based.

Slippery Body (Ex): The Marais Dream Eel’s heavy mucus coating grants it a +8 racial bonus on Escape Artist checks. Creatures attempting to grapple or hold a Marais Dream Eel take a -4 penalty on grapple checks unless wearing protective gloves or gauntlets. Any creature maintaining physical contact with the eel for more than 1 round must immediately attempt a DC 12 Fortitude save against the eel’s venom.

Anguilliform Resilience (Ex): The Marais Dream Eel’s elongated flexible skeleton, fused fin structure, distributed organ layout, and thick slime coating make it unusually resistant to injury for its size. The eel gains Damage Reduction 2/bludgeoning and a +4 racial bonus on saves against being pinned, crushed, or stunned. In addition, the eel may survive out of water for up to 1 hour so long as its skin remains moist.

Skills: A Marais Dream Eel has a +8 racial bonus on Swim checks and may always choose to take 10 on Swim checks, even if distracted or endangered. It may use the run action while swimming in a straight line.

Physical Description

The Marais Dream Eel is a true eel belonging to a bizarre marsh-adapted lineage of anguilliform fish native to the blackwater wetlands surrounding Ville des Marais. Long, ribbon-bodied, and almost serpentine in appearance, the creature lacks visible pelvic fins entirely, while its dorsal, anal, and caudal fins merge into a single continuous undulating membrane running nearly the full length of the body. Adult specimens typically range between three and five feet long, though ancient females dwelling deep within isolated marsh channels have reportedly reached nearly seven feet.

Its skin is smooth, scaleless, and perpetually coated in an unusually thick layer of translucent mucus that smells faintly of wet moss, river silt, and bitter medicinal herbs. Beneath lantern light, this slime reflects oily iridescent blues and greens reminiscent of spilled alchemical fluid floating atop water. The coating serves several purposes simultaneously - protecting the eel from parasites, reducing friction while moving through mud and reeds, preventing dehydration during brief periods on land, and making the creature maddeningly difficult to restrain.

The head resembles that of a small moray eel, narrow yet powerfully muscled, with recurved translucent teeth designed primarily for grip rather than tearing flesh. Along the underside of the jaw rest paired venom glands visible beneath the thin flesh as faintly glowing blue sacs. When distressed or aggressive, these glands pulse visibly before secreting an oily psychoactive toxin across the creature’s teeth and gums. Experienced marshfolk learn quickly to recognize the glow. Inexperienced marshfolk become stories told by experienced marshfolk.

Unlike many fish, the Marais Dream Eel is capable of surviving outside water for surprisingly long periods provided its skin remains damp. During flood season, they have been observed writhing through submerged streets, drainage canals, and flooded graveyards in search of prey or spawning grounds. Their movement across wet earth is deeply unsettling - less like a fish flopping and more like a length of living rope pulling itself forward with terrible patience.

Lore

The Marais Dream Eel occupies a deeply uncomfortable place within the ecosystem and culture of Ville des Marais. To fishermen, they are pests that foul nets and occasionally poison careless handlers. To physicians and ritual practitioners, they are dangerous but potentially valuable biological curiosities. To goblin smugglers, however, they are entrepreneurial opportunity given flesh and slime.

Natural philosophers remain fascinated by the species’ extraordinary durability. Unlike many fish, the eel’s elongated anatomy distributes vital organs across a flexible body structure that tolerates blunt trauma surprisingly well. Their skeletons bend rather than break, their organs sit recessed behind thick musculature, and their mucus coating makes them difficult for predators to grip securely. Marsh hunters often complain that injured Dream Eels continue writhing long after lesser creatures would have died. Several frustrated trappers have described the experience as “trying to stab wet rope possessed by a curse.”

The creature’s hallucinogenic venom remains the primary source of both fascination and civic concern. Properly diluted doses are occasionally employed during funerary rites, trauma rituals, ancestor communions, and certain mystical ceremonies intended to confront grief or buried memory. Users frequently describe hearing impossible music drifting through fog, witnessing drowned relatives speaking from riverbanks, or perceiving the world as though viewed through rippling water. Whether these experiences represent spiritual truth or simple neurochemical chaos is debated endlessly throughout the city’s academies and shrines.

The illegal venom trade surrounding the species is extensive. Smugglers transport living eels inside water-filled barrels disguised as fish stock, medicinal cargo, or “agricultural drainage specimens,” whatever those are allegedly supposed to be. Improper refinement is catastrophically dangerous. Victims of poorly distilled venom mixtures have wandered naked into swamp water believing themselves immune to drowning, attempted conversations with statues, or spent hours convinced they themselves were riverboats. One particularly infamous incident involved an intoxicated goblin dockmaster attempting to issue legal permits to a decorative coat rack.

The city’s Ministry of Civic Health technically regulates all venom extraction and transport permits, though enforcement becomes increasingly theoretical the farther one travels into the outer marshes. Goblin import syndicates continue attempting to circumvent restrictions with admirable creativity and horrifying consistency. The phrase “medicinal swamp eels” has, over the years, become less a legitimate trade classification and more an immediate warning sign that someone nearby is about to make a truly terrible decision.

An Opabinia Rexalis is a sinuous, three-foot-long aberration whose segmented body undulates with a soft, almost petal-like rhythm beneath the water’s surface. Its most striking feature is the cluster of five glossy, bead-like eyes arranged across its head, each moving independently, granting it a constant awareness of its surroundings. Extending from beneath these eyes is a long, flexible proboscis ending in a small but vicious grasping claw, capable of snapping shut with unsettling precision. Along its sides, soft lateral lobes ripple gently, aiding in its eerie, silent locomotion through still water.

The creature’s dorsal surface is lined with delicate gill structures that fan outward like pale fronds, filtering oxygen even in stagnant, low-quality water. Its coloration is naturally mottled - pale pinks, muted reds, and swampy greens - but when submerged, its flesh subtly shifts hue and opacity, blending almost perfectly with the murky environment. When still, it becomes nearly impossible to detect, appearing as nothing more than a distortion in the water or a trick of the light.

Opabinia Rexalis are ambush predators. They prefer to remain motionless just beneath the surface, their bodies aligned with submerged roots or driftwood. When prey approaches - whether a fish, animal, or unwary humanoid - the creature lashes out with its proboscis, seizing flesh and anchoring itself with surprising strength. Once attached, it begins to feed, drawing blood through a specialized channel within its appendage while maintaining its grip with the clawed tip.

Despite their alien anatomy, these creatures are not overtly aggressive unless provoked or hungry. They rely on patience rather than pursuit, often allowing potential prey to pass if the risk is deemed too high. However, in areas where they gather in clusters, their behavior becomes more opportunistic, and multiple individuals may converge on a single target, creating a sudden and horrifying feeding frenzy beneath otherwise calm waters.

Lore

Little is recorded of Opabinia Rexalis in formal scholarship, largely because early accounts were dismissed outright. Initial sketches, often produced by isolated naturalists or delirious explorers, were ridiculed for their implausibility - five eyes, a grasping feeding limb, a body plan that defied accepted anatomical logic. These reports were quietly shelved or outright destroyed, labeled as exaggeration or madness.

It was only when physical specimens were recovered - some preserved, others violently alive - that the academic world was forced to reconsider. Even then, acceptance came grudgingly. Many scholars attempted to reinterpret the creature within known biological frameworks, often downplaying or ignoring its more unsettling features. A few, however, recognized it for what it represented: a living contradiction to the assumed boundaries of natural design.

In the bayous and lowlands, local populations have long known of the creature, though under different names. It is sometimes called the “Stillwater Clutch” or “Five-Eyed Leech,” and is associated with disappearances in shallow waters. Stories describe it as a patient watcher, something that sees from all directions at once, waiting for the moment when movement betrays the living.

More troubling are the rarer accounts suggesting that Opabinia Rexalis may not be entirely natural to the current age. Some believe it to be a remnant of an older world, a creature whose design predates the modern order of life. Others whisper that it emerges more frequently in places where reality is thin - where the boundaries between what is and what was begin to blur.

Kelwyn’s Notes

Ah… yes. This one. I recall, with uncomfortable clarity, the first time I encountered its likeness - not in the flesh, you understand, but inked hastily across a page that bore all the hallmarks of a mind under quiet siege. Five eyes, a reaching limb, a creature assembled as though nature had briefly forgotten her own rules. I confess, I dismissed it. Not out of arrogance, I think - but out of necessity. One cannot afford to believe everything one sees in ink.

And yet, here it is. Not merely real, but consistent. The same structure, the same absurdities, repeated across accounts separated by geography, culture, and time. This is not invention - it is persistence. I have since uncovered references to such organisms in documents that should not exist, attributed to expeditions into places that are now… conspicuously absent. Entire bodies of study, orphaned of origin. It leads one to an unsettling hypothesis: that this creature does not belong to our world in the way we assume most life does, but is instead a survivor - or perhaps an exile - from a place that no longer exists at all.

Among those few who have encountered it and lived, there is a peculiar commonality in their accounts. Not merely fear - though there is plenty of that - but a deeper disturbance, a quiet unraveling. They speak of it as something that remembers being elsewhere, as though its presence alone carries the weight of a place that should no longer be. Those who study it too closely tend toward obsession, and in time, a certain resignation - as though they have glimpsed a truth they cannot comfortably return from.

I do not believe this species is native to our reality. There are whispers - fragments, scattered and half-erased - suggesting that an entire dimension was deliberately unmade in an effort to eradicate organisms of this design. If that is so, then this creature represents not merely a curiosity, but a failure. A remnant that slipped through whatever curtain was drawn to end its kind. That it is now unbelievably rare offers little comfort. Rarity, after all, is not the same as safety.

It is tempting to call such a thing an error. I would advise against it. Errors do not survive the death of their own world. Errors do not endure, adapt, and wait in silence beneath still water. No… this is something that was meant to exist - somewhere. And now, quite inconveniently… it exists here.

DESCRIPTION

The Blackwater Catfish is a hulking predator of slow, tannin-dark waters where visibility is measured in inches and sound travels farther than sight. Its long, whiskered face drifts just above the riverbed, barbels tasting the currents for movement, blood, and the subtle tremors of living flesh. Its hide is thick, slick, and dark as drowned wood, often scarred from territorial battles or failed attempts by desperate prey.

Measuring between eight and twelve feet in length, these creatures are deceptively still hunters. They settle into silt or beneath submerged roots, becoming indistinguishable from the environment until the moment they strike. What follows is not a chase, but a violent, sudden absence - a splash, a churn of mud, and then silence.

COMBAT

A Blackwater Catfish attacks from concealment, preferring targets at the water’s edge or wading in shallow depths. It attempts to grapple immediately, dragging prey into deeper water where resistance quickly turns to panic and drowning.

Improved Grab (Ex): If the catfish hits with its bite, it may attempt to start a grapple as a free action without provoking attacks of opportunity.

Swallow Whole (Ex): A Blackwater Catfish can swallow a grabbed opponent of Large size or smaller. A swallowed creature takes 2d6+6 bludgeoning damage plus 1d6 acid damage per round. The gizzard (AC 13) requires 15 damage to cut free. Capacity: 2 Large, 4 Medium, or 8 Small or smaller creatures.

Thrash (Ex): While grappling, the catfish violently twists, dealing an additional 1d8+6 damage each round it maintains the grapple.

Murky Water Adaptation (Ex): The catfish ignores concealment penalties from silt or dark water and gains a +4 racial bonus on Listen and Spot checks in aquatic environments.

Skills: A Blackwater Catfish has a +8 racial bonus on Swim checks and can always choose to take 10 on Swim checks, even if distracted or endangered. It can use the run action while swimming in a straight line.

LORE

Locals rarely agree on much, but on this they are unified - if the water is black enough to hide your hands, it is deep enough to hide a catfish. Livestock vanish. Dogs refuse to drink. Boats drift back empty. And always, the water returns to stillness too quickly, as though nothing at all had happened.

These creatures are not merely opportunistic feeders - they learn. Those that survive long enough begin to recognize patterns: the hour fishermen arrive, the places children play, the habitual crossings of livestock. In time, a Blackwater Catfish does not simply hunt - it waits for you specifically.

Some riverfolk leave offerings of meat or blood at certain bends, believing it will keep the larger specimens satisfied. Others say this only teaches the creature that humans are a reliable source of food. Neither group has proven the other wrong.

DESCRIPTION

This variant of the Blackwater Catfish is immediately recognizable to those unfortunate enough to have seen it and lived. Its body bears a muted olive-green coloration that blends seamlessly with algae-choked waters, broken only by a faint, shadowy black stripe running along its underside. This marking is rarely visible from above, rendering the creature nearly invisible until it turns - often at the exact moment it strikes.

Its barbels are longer and more sensitive than those of its kin, constantly tasting the water for signs of movement. Up close, subtle ridges can be seen along the jawline and near the base of the tail - the source of its venom. Wounds inflicted by this creature are often deceptively small, yet far more dangerous than they appear.

COMBAT

The striped venomtail relies on the same ambush tactics as other Blackwater Catfish, but it is notably more aggressive once it has made contact. It often bites and releases smaller prey, allowing the venom to weaken the target before returning to feed at its leisure. Against larger prey, it grapples as normal, letting the toxin hasten exhaustion and drowning.

Improved Grab (Ex): As Blackwater Catfish.

Swallow Whole (Ex): As Blackwater Catfish.

Thrash (Ex): Deals an additional 1d8+7 damage each round it maintains a grapple.

Venom (Ex): Injury, Fortitude DC 18, initial damage 1d4 Strength and 1d4 Dexterity, secondary damage 1d6 Strength. The save DC is Constitution-based. A creature reduced to 0 Strength by this poison is unable to swim and immediately begins to drown if in water.

Murky Water Adaptation (Ex): As Blackwater Catfish.

Skills: A Blackwater Catfish, Striped Venomtail has a +8 racial bonus on Swim checks and can always choose to take 10 on Swim checks, even if distracted or endangered. It can use the run action while swimming in a straight line.

LORE

Among those who live along blackwater shores, this creature is often treated with greater fear than its larger cousins. Not because it is bigger - but because it is cruelly efficient. Victims are not always taken immediately. Some are found hours later, half-submerged, unable to move, their bodies failing them while the water quietly claims what remains.

Fishermen tell of lines going slack without struggle, only to find the catch gone and the hook bent or broken. Others speak of a sudden numbness in their limbs after brushing against something unseen, followed by a creeping weakness that leaves them unable to stand, let alone flee.

There is a saying in the bayou: “If the water takes you fast, be grateful. If it lets you linger, it’s the striped one.”

More troubling still is the relationship between these creatures and the Mireborn. At a distance, they resemble people - thin, stooped, and watchful. Up close, that illusion rots away. Their skin bears a sickly olive cast, stretched too tight in some places and sagging in others, as though the body beneath has forgotten its proper shape. Their hair hangs in long, damp strands resembling Spanish moss, often clotted together with filth and stagnant water. Their eyes are wrong - not in movement, but in stillness, as though they receive the world rather than look at it. Boils, lesions, and slow-weeping sores mark nearly every inch of exposed flesh. The smell that follows them is brackish and faintly sweet, like something long steeped in still water. They rarely speak as individuals. Instead, they murmur - overlapping whispers that only form meaning when heard together.

It is said the Mireborn seek out the striped venomtails with patient, deliberate intent, luring them into shallow, choking waters where nets of woven reed and bone await. They do not kill the creature quickly. They wound it. They bleed it. They take from it what they need.

The venom is collected in crude vessels - hollowed gourds, skulls, or thick glass when such things can be stolen - and worked into their weapons with unsettling care. Spears, hooks, and jagged blades are coated in the toxin, not for swift death, but for the slow undoing of those struck.

Those who have survived such wounds speak of a familiar sensation - not pain, but surrender. Muscles loosening. Strength fading. The body forgetting how to resist.

And in the distance, through the reeds and still water, the Mireborn murmur together - not in triumph, but in something closer to recognition.
