History of the Shadow Marches
"History? You want history? Look at the mud. There's a war under there that's older than your languages. There's a dragon's bones under that. There's a god's nightmare under those. And somewhere at the very bottom, before all of it, there's just the swamp. The swamp was here first and the swamp will be here last. That's your history." — unnamed Torrn elder, speaking to a Korranberg chronicler
Before the Orcs
The history of the Shadow Marches begins before anyone was there to record it — and in a sense, that is the defining characteristic of Marcher history. It is a story told in layers of silt rather than chapters of ink, and the oldest layers belong to no mortal people at all.
The land that would become the Shadow Marches was shaped in the first age of the world, when the Progenitor Dragons — Siberys, Eberron, and Khyber — divided creation among themselves. The swamps sit atop some of the most ancient and volatile planar geography on Khorvaire. Manifest zones tied to Xoriat, the Realm of Madness, and Kythri, the Churning Chaos, riddle the deep interior — pockets of alien influence where the boundaries between planes wear thin, where time moves strangely, and where mundane life twists into shapes that suggest the laws of nature were only ever a polite suggestion. These zones were not created by the daelkyr invasion, as outsiders sometimes assume; they predate it by millennia, woven into the fabric of the swamp from the moment Eberron took form. The daelkyr would later exploit them. They did not make them.
The Marches were also shaped by the Age of Demons — the epoch-spanning war between the dragons of Argonnessen and the fiendish overlords. Some Marcher oral traditions speak of titanic trees that once grew to impossible heights, struck down in cataclysms so old that their wood became the bones of the swamp. Whether these are literal memories or metaphor, the deep Marches contain geological features that no scholar has satisfactorily explained: stone foundations on islands that match no known civilization, root structures that seem too regular to be natural, and soil horizons that suggest sudden, catastrophic disruption at a depth consistent with the Age of Demons.
None of this was written down, but the swamp remembers it in its own way.
The Orc Homeland (pre–16,000 YK)
No one knows precisely when the orcs came to the Shadow Marches, or where they came from before that. The Dhakaani Empire, whose records are considerably more reliable than orcish oral tradition, confirms that orcs were present on Khorvaire long before the founding of Dhakaan — a native people of the continent, as deeply rooted as the goblinoids themselves. What the Dhakaani records also confirm is that orcs were never a unified civilization. They lived in small, fiercely independent tribes, bound by kinship and territory, and they had no interest in building empires, accumulating wealth, or organizing beyond the scale of the family group.
The orcs are, by nature, intensely passionate and deeply individualistic — qualities that produce extraordinary loyalty within small groups and make large-scale coordination nearly impossible. A tribe of forty orcs who all know each other's names can accomplish remarkable things. An army of ten thousand orcs answering to a faceless command structure will tear itself apart before the enemy arrives. This is one of the primary reasons the orcs never dominated Khorvaire despite being among its oldest inhabitants, and it is one of the primary reasons the Empire of Dhakaan was able to drive them into the margins.
The Dhakaani pushed the orcs into the harshest and least desirable corners of the continent: the Demon Wastes, the depths of the Ironroot Mountains, and the swamps of the western coast. The orcs did not conquer the Shadow Marches. They were exiled to them. And then, in the way of all exiles, they made the place their own — learning its rhythms, reading its dangers, and sinking roots so deep that thousands of years later, no force in the world would be able to pull them out.

Vvaraak's Gift (circa –16,000 YK)
Over fifteen thousand years ago — before the Dhakaani Empire reached its golden age — a green dragon named Vvaraak left Argonnessen and crossed the world to find the orcs.
Vvaraak was a child of Eberron in the truest sense — a dragon devoted to the living world and the natural order. In her study of the Draconic Prophecy, she had foreseen a catastrophe that would wound reality itself: an invasion from beyond the planes that only the younger races could stop. She brought this warning to the Conclave of Argonnessen, and the Conclave — with the cold pragmatism that defines dragonkind — told her they would act only when a clear threat to Argonnessen existed, and not before. Vvaraak was not willing to wait.
She abandoned her flight, traveled to the Shadow Marches, and began teaching the orcs the secrets of druidic magic — the language of the natural world, the art of working with stone and soil, the ability to read the future in the movements of the Ring of Siberys and the moons. She taught them to sense the places where the planes pressed close to Eberron, and she taught them what to do when those places broke open.
The orcs she trained became the first Gatekeepers. Vvaraak stayed in the Marches for less than a century; she charged her students to remain ever vigilant against the threat she had foreseen, and then she vanished. Her final fate is unknown. Some say she died in the Marches and that her hidden cave holds secrets tied to the Prophecy. Some say she returned to Argonnessen and that her rebellion was actually a calculated move on behalf of the Conclave — that the dragons planned the whole thing. Some say she descended into Khyber to teach other races in the deep places. The Gatekeepers do not know, and after sixteen thousand years, they have stopped expecting an answer.
"My grandmother said the Old Ways were older than words. That the first Gatekeepers learned to speak to the swamp before they learned to speak to each other. I don't know if that's true. But I know the frogs shut up when a Gatekeeper walks past, and I've never seen them do that for anyone else." — Marcher half-orc, name unrecorded, speaking to a Tharashk factor
The Daelkyr War (circa –9,000 YK)
The threat Vvaraak foresaw arrived seven thousand years after she left.
The daelkyr — alien lords of Xoriat, the Realm of Madness — pierced the barriers between the planes and established footholds in the depths of Khyber beneath Khorvaire. From those footholds they unleashed armies of aberrations: mind flayers, beholders, dolgaunts, dolgrim, and things that have never been satisfactorily named by any surface scholar. The invasion's first and greatest victim was the Empire of Dhakaan, the goblinoid civilization that had dominated Khorvaire for tens of thousands of years. The daelkyr's forces tore through Dhakaani legions and shattered the empire from the inside, corrupting its people, undermining its institutions, and leaving devastation across the continent.
In the Shadow Marches, the war was intimate and terrible. The daelkyr exploited the region's existing manifest zones as staging grounds. They corrupted orcs who were not strong enough to resist their influence, turning them into soldiers against their own kin. Aberrations bred in the deep swamps. The fighting was not a series of grand battles — the orcs had no armies in any conventional sense — but a grinding, generational struggle fought in bogs, in caverns, on the edges of manifest zones where reality itself could not be trusted.
The Gatekeepers were the weapon that ended it. Using the druidic magic Vvaraak had taught them, the orc druids forged seals of extraordinary power — magical wards that bound the daelkyr in the depths of Khyber, sealed the gates between Eberron and Xoriat, and prevented the plane of madness from ever again becoming coterminous with the world. They could not kill the daelkyr. But they could cage them, and they did.
The cost was staggering. The Gatekeepers were few, and the effort of forging and maintaining the seals consumed the lives and power of many of their strongest druids. The broader orc population was devastated. And the victory was incomplete — the daelkyr were imprisoned, not destroyed, and their servants and spawn remained loose in the swamps, burrowed into the earth, hidden in the dark places that the seals could not reach. The Marches were scarred in ways that would never fully heal. Manifest zones that had been merely strange became actively dangerous. The deep swamp became infested with aberrations that would breed and persist for millennia. And worst of all, many orcs who had been corrupted by the daelkyr did not return to sanity when the war ended. They carried the madness forward, passing it to their children, building it into traditions and rituals and belief systems that would eventually become the cults of the Dragon Below.
The Gatekeepers did not celebrate their victory. They returned to the seals and began the vigil that has continued, unbroken, for nine thousand years.
ORAL HISTORY — recorded by a Korranberg chronicler, attributed to Saala Torrn, elder Gatekeeper, circa 990 YK
"The songs say we sealed the dark lords in the belly of the world and saved creation. The songs do not say that we cannot remember which seals are real and which are stories we told to protect the real ones. Nine thousand years is a long time to keep a secret, even from yourself."
The Long Silence (circa –9,000 to –1,600 YK)
For roughly seven thousand years after the Daelkyr War, the Shadow Marches were silent — not peaceful, exactly, but invisible to the wider world. The orcs went back to their lives. The tribes hunted, fished, fought each other in small-scale territorial disputes, and observed the traditions of the Gatekeepers or the cults with approximately equal fervor and approximately equal ignorance of what either tradition truly meant. The Dhakaani Empire was shattered and no new power arose in western Khorvaire that cared about a pestilential swamp. Humanity arrived on the eastern coast around –3,000 YK, and for the next fourteen centuries the expanding human kingdoms had no contact whatsoever with the Marches. The orcs did not know the humans existed. The humans did not know the Marches existed. The swamp went on being the swamp.
This was, by any external measure, a period in which nothing happened. But the Gatekeepers would disagree. They maintained their seals. They watched the skies. They fought aberrations that crept up from the deep places. They conducted the annual ceremonies that renewed the wards. They trained new initiates and passed their knowledge — imperfectly, inevitably — from one generation to the next through an oral tradition that was already thousands of years old. The vigil did not make history. It made the absence of history possible.
And during these seven thousand silent years, the cult traditions also grew. The madness the daelkyr had sown took root in families and communities, evolving into belief systems that seemed, to their followers, perfectly rational. A grandmother who kept a gibbering mouther in the cellar and fed it the bones of the family dead was not a servant of Kyrzin; she was practicing the traditions she had learned from her own grandmother, in a chain stretching back to the original corruption, and she believed — with perfect sincerity — that she was honoring the voices of the departed. The cults spread quietly, the way mold spreads in damp wood, and by the time the first humans arrived, the spiritual landscape of the Marches was already divided along lines that have never been resolved.
The Sarlonan Refugees (circa –1,600 to –1,400 YK)
In distant Sarlona, around –1,600 YK, the Sundering began. Over two centuries, quori manipulation and human greed tore the Sarlonan kingdoms apart in a cascade of wars, riots, and collapse. Waves of refugees fled across the ocean — some to Khorvaire's eastern coast, where they joined the human communities already established in Lhazzar and Karrnath. Others sailed further, reaching the western shores of the continent, and among the places they washed up was the Shadow Marches.
These were not colonizers. They were desperate people arriving in a hostile land with nothing, and they survived because the orcs — characteristically — tolerated them without particularly welcoming them. The relationship was not a treaty or an alliance. It was simply coexistence: the newcomers settled where the orcs allowed them to settle, learned what the orcs were willing to teach them, and gradually, over generations, the two peoples merged.
Intermarriage produced the first half-orc population — the jhorgun'taal, the bridge of two bloods — that would become one of the defining features of the region. Human customs blended with orcish ones. The language that emerged, Azhani, was a hybrid of Goblin, Riedran, and traces of the ancient Orc tongue. Towns replaced some of the more transient tribal settlements. Metalworking arrived. The blended communities that resulted became the Marcher clans — the culture that would eventually give rise to House Tharashk. Eventually, the tribes of orcs and humans became so intermingled that there are now very few full-blooded orcs or full-blooded humans in the tribes of the Shadow Marches, and they're known collectively simply as the orc-kin, or the jhorgun'taal.
Not all orcs welcomed the change. The tribes that maintained the oldest traditions viewed the blending with wariness, and some withdrew deeper into the swamp to preserve their ways. The division between clans and tribes — between those who embraced humanity and those who held to the ancient patterns — dates to this period, and it has never been resolved.
The humans, for their part, brought their own spiritual sensibilities. The Sarlonan refugees were not blank slates; they carried traditions, superstitions, and religious instincts of their own, and these blended with the existing Gatekeeper and cult traditions in unpredictable ways. Some refugees were drawn to the Gatekeeper practices, which resonated with their own primal traditions. Others were drawn to the cults, which offered the intensity and certainty that displaced, frightened people often seek. The spiritual landscape of the Marches became more complex — and more volatile.
"The old folk say that before the humans came, the orcs had no word for 'stranger.' Not because they had no enemies — they had plenty — but because everyone they knew, they knew by name. The humans brought the concept of the stranger with them. Some of the old folk say they also brought the concept of the lie." — Marcher saying, provenance uncertain
The Mark of Finding (circa –1,000 YK)
Five hundred years after the Sarlonan refugees arrived, something manifested among the blended clans that no one had anticipated and no one could explain.
Around –1,000 YK, members of certain Marcher clans began bearing the Mark of Finding — a dragonmark that sharpened the senses and guided its bearer unerringly toward whatever they sought, whether prey, person, or object. The Mark of Finding is unique among dragonmarks in that it appears in orcs and orc-kin — a fact that reflects the blended heritage of the clans where it first arose. The Marchers did not know what the marks meant. They had never heard of dragonmarks. They had no contact with the Twelve, which had been established centuries earlier on the far side of the continent. They simply knew that certain hunters in certain families had a gift, and they used it.
The Mark of Finding existed in the Shadow Marches for five hundred years — half a millennium — before anyone in the wider world knew about it. This fact alone tells you everything you need to know about the degree of isolation the Marches maintained. A dragonmark was present in the population for five centuries, manifesting in family after family, and the Twelve — the organization whose entire purpose was to identify and regulate dragonmarks — had no idea it existed.
The Sivis Expedition and the Founding of House Tharashk (498 YK)
In 498 YK — roughly fifteen hundred years after the Mark of Finding first appeared — a House Sivis expedition reached the Shadow Marches. The gnomes were exploring the western coast, mapping terrain and cataloguing resources, and what they found in the Marches changed the region permanently.
The Sivis explorers made two discoveries. The first was that the Marches contained significant deposits of Eberron dragonshards — the crystallized blood of the Progenitor Dragon, essential to the magical economy of every civilized nation. The second was that members of the local population bore a dragonmark the Twelve had never seen.
The Sivis gnomes immediately recognized the opportunity; they helped three of the most prominent marked clans — Aashta, Torrn, and Velderan — organize into a formal house. House Tharashk was born, taking the dragonne as its emblem. The Twelve recognized it with unusual speed, and the Finder's Guild was established to license bounty hunters, inquisitives, and dragonshard prospectors.
The founding of Tharashk was the most transformative event in the Marches since the arrival of humans. For the first time, the region had a connection to the wider world — a formal institution that could negotiate with the dragonmarked houses, trade with the Five Nations, and represent Marcher interests on the continental stage. Zarash'ak, which had been a modest trading settlement, began to grow. Torrn druids raised the massive murk oaks that would support the City of Stilts. Dragonshard prospecting expanded. Marcher orc-kin — bounty hunters, inquisitives, trackers — began appearing in the cities of the Five Nations, and for the first time in history, the people of Khorvaire had a reason to think about the Shadow Marches.
The transformation was not total. Most of the Marches remained untouched. Tharashk's influence extended through the clans but barely reached the tribes, many of which continued to live exactly as they had for thousands of years. The founding of the house did not make the Shadow Marches a nation. It made them visible.
PRIVATE CORRESPONDENCE — House Sivis expedition records, circa 498 YK (translation from the original Gnomish)
"The natives are astonishingly good trackers — better than any Medani inquisitive I have worked with, and I say that knowing full well it borders on heresy. The mark on their skin is unmistakable. They have been using it for generations with no formal training whatsoever. We are looking at raw, uncut gemstone. Someone needs to teach these people what they have."
Under Galifar's Shadow (498–894 YK)
Unlike the Mror Holds and the Lhazzar Principalities, which paid tribute and fealty to Karrnath, the Shadow Marches were never conquered by Galifar. This was not because the Marches were too strong to take. It was because the Marches had nothing that made the difficulty of conquest and occupation worth the trouble.
The swamp was impassable by any conventional army. The population was diffuse, mobile, and knew the terrain intimately. There were no cities to seize, no treasuries to loot, and no centralized authority to negotiate with or subjugate. Galifar — and later Karrnath, Breland, and every other nation with theoretical claims to the western coast — looked at the Shadow Marches, calculated the cost of pacifying a thousand miles of trackless bog populated by mud-dwelling orcs, and decided to leave them alone, so long as they were free to buy the dragonshards from Tharashk.
House Tharashk's growth during this period was steady but quiet. The house expanded dragonshard prospecting, built Zarash'ak into a functional port, and began placing agents and offices in the cities of the Five Nations. Tharashk bounty hunters and inquisitives earned a reputation for competence and discretion. The Mark of Finding proved invaluable for locating fugitives, lost objects, and hidden dragonshard deposits. But the house remained the youngest, the smallest, and the least politically connected of the dragonmarked houses — a swamp operation run by orc-kin in a world that still thought of them as savages.
Back in the Marches, the centuries passed much as they always had. The Gatekeepers maintained their seals. The cults observed their traditions. The clans traded and the tribes hunted. The relationship between the Marches and the wider world remained mediated almost entirely through Tharashk, and most Marchers — particularly the tribes — were unaware that the wider world existed in any meaningful sense.
The Last War (894–996 YK)
The Shadow Marches did not fight in the Last War. Most Marchers did not even know it was happening.
This is not an exaggeration. When King Jarot died in 894 YK and the Five Nations fractured, the Marches had no stake in the Wynarn succession, no alliance with any belligerent, and no army to contribute even if they had wanted to. Marcher tribes — the majority of the population — did not know the names of the nations that were fighting, let alone the reasons. The clans closest to Tharashk operations were vaguely aware that the east was at war, in the same way a farmer is aware of a storm on the horizon.
House Tharashk, however, participated enthusiastically. The house recruited Marcher orc-kin as mercenaries, and Tharashk soldiers served in every theater of the war. The experience transformed the house — bringing wealth, experience, and continental connections that the swamp-bound clans had never possessed. The most significant development came late in the conflict, when Clan Aashta devised the Dragonne's Roar — the brokering of monstrous mercenaries from the newly declared nation of Droaam. Beginning in 988 YK, Tharashk served as the intermediary between the Daughters of Sora Kell and the nations of Khorvaire, supplying ogre laborers, gnoll soldiers, and troll shock troops to clients across the continent. The Dragonne's Roar made Tharashk rich and powerful in ways that dragonshard prospecting alone never could have, and it established the house as the sole commercial bridge between Droaam and the rest of the world.
For the Marches themselves, the war's most visible effect was the expansion of Zarash'ak. Tharashk poured its new wealth into the city, transforming it from a functional port into something approaching a genuine urban center. Other towns grew as well, as Tharashk worked to develop infrastructure connecting the clans. This brought the house into direct tension with the tribes, who viewed the expansion as an intrusion into territory they had occupied for millennia — and with the Gatekeepers, who feared that new construction and mining operations could disturb the seals that kept the daelkyr imprisoned.
"They told me the east was at war. I asked them which east. They said all of it. I went back to my nets." — attributed to a Marcher fisherman, date uncertain
The Treaty of Thronehold and the Postwar Marches (996 YK–Present)
The Treaty of Thronehold ended the Last War in 996 YK. The Shadow Marches were not recognized as a sovereign nation — they had no delegation at the negotiations, no unified government to grant sovereignty to, and no particular desire to be recognized. The Marches are simply not a nation in any sense that the treaty's architects understood the term.
What the postwar period has brought is pressure — not military, but economic and cultural. House Tharashk emerged from the war wealthier and more ambitious than ever. It has expanded Zarash'ak dramatically, is working to transform other settlements into cities, and is pushing mining operations deeper into the swamp. Every expansion disturbs more territory, displaces more tribal communities, and risks more damage to the seals that the Gatekeepers have maintained for nine millennia.
The tension between Tharashk's commercial ambitions and the Gatekeepers' ancient vigil is the defining fault line of the postwar Marches. The house needs to dig. The druids need the digging to stop. The tribes want both of them to leave the deep swamp alone. And beneath it all, the daelkyr wait in their prisons — patient, alien, and ageless — while the wards that hold them grow older every year and the people who maintain them grow fewer.
