temperate continentforest islands
Arborisle is a vast continent with a mostly temperate climate, though scattered tropical zones dot its center and its shores remain wet, windy, and cool even in summer. The land is named for its abundance of forests, which often form large circular expanses like islands of trees, giving the continent its name. The north is dominated by human settlements and dotted with lakes and ponds, while the south is veined with rivers and streams and is the stronghold of high elves and wood elves. Human civilization's economic strength draws many humanoids to the northern lands, and even the orcs here are more civilized than their tribal cousins elsewhere. The continent hosts all manner of flora and fauna, from extreme tropical life to simpler critters and peoples, making it a land of both opportunity and danger.
New Haven is the most important city on Arborisle, sitting at the continent's center and serving as the headquarters of the Adventurer's Guild. Its name honors the old city of Haven, which was destroyed in a war between humans and the aggressive, tribal elf-like Fiór, and 'New' marks its rebuilding atop the ruins. The city is a cultural hub where humans and elves work in peace, with a population of about sixty percent human, thirty percent elf, and ten percent other humanoids. It is a bustling center of trade, politics, and adventure, where the guild's presence draws heroes and opportunists from across the continent. The city's streets are a blend of rebuilt stonework and new architecture, with the old Haven's bones visible in some foundations.
The Adventurer's Guild is the premier organization for monster hunting and dangerous tasks on Arborisle, with its main headquarters in New Haven. It hands out missions to adventurers and heroes, paying them to deal with threats ranging from rogue beasts to bandit gangs and ancient ruins. The guild operates on a ranking system, where successful missions raise an adventurer's standing and unlock more dangerous, better-paying work. Its halls are always busy, with quest boards, seasoned veterans swapping tales, and new recruits seeking their first contracts. The guild also acts as a mediator between adventurers and local authorities, ensuring that monster culls and relic retrievals don't spark political incidents.
The Fiór were a race of tribal, aggressive elf-like people who once warred with humans and destroyed the original city of Haven. They are rumored to have gone extinct or migrated elsewhere after the conflict, but no one is certain. Modern elves on Arborisle claim no cultural or political allegiance to the Fiór, and speaking of them often stirs unease. Ruins attributed to the Fiór are scattered across the continent, often holding strange artifacts or dangerous remnants of their magic. Some whisper that the Fiór still live in hidden enclaves, waiting for a chance to reclaim their old lands.
The northern section of Arborisle is scattered with lakes and ponds, ranging from small kettle ponds to vast inland seas. These waters are vital to human settlements, providing fish, fresh water, and trade routes, and many towns have grown up along their shores. The lakes are home to various aquatic creatures, some harmless and some monstrous, like giant pike and freshwater drakes. Fisherfolk and traders know that the deep spots of the larger lakes can hide sunken ruins or treasure. A traveler might find a quiet village by a lake, only to learn it's plagued by a water spirit demanding tribute.
The south of Arborisle is veined by countless rivers and streams, carving through the lands of the high elves and wood elves. These waterways are lifelines for elven communities, used for travel, irrigation, and mystical rituals. The rivers often run through dense forests, where the banks are lined with ancient trees and hidden elven dwellings. Some rivers are known to be enchanted, with waters that glow faintly at night or that grant strange blessings to those who drink them. The streams can be dangerous, too, with rapids, lurking predators, and the occasional ruined bridge from older times.
High elves are one of the dominant elven peoples of Arborisle, primarily dwelling in the south along the rivers and in elegant cities built into hills and cliffs. They are known for their long lifespans, refined magical arts, and a certain aloofness toward shorter-lived races. High elf society is structured around noble houses and arcane academies, where politics and magic are deeply intertwined. They treat humans with polite distance, though trade and adventuring have brought them into regular contact. A high elf might be a haughty mage, a wise counselor, or a stern guardian of ancient elven laws.
Wood elves are the other dominant elven people of Arborisle, living in the deep forests of the south and the scattered circular groves. They are more reclusive than high elves, favoring harmony with nature and a hunter-gatherer lifestyle. Wood elf communities are often hidden, with treehouses and camouflaged paths that outsiders rarely notice. They are skilled archers, trackers, and herbalists, and they hold deep reverence for the ancient trees of their homes. While wary of strangers, wood elves can be fierce allies if their forests are threatened.
The orcs of Arborisle are more civilized than their tribal cousins on other continents, lacking strong footholds or aggressive war-bands. They live in integrated communities, often working as smiths, mercenaries, or laborers in human and elven towns. Many orcs have adopted local customs, and some have risen to respected positions in the Adventurer's Guild. They still retain a strong warrior culture, but it's expressed through honorable combat and protection of their communities. An orc adventurer might be a gruff but loyal companion, carrying the weight of proving their people's worth.
Scattered across Arborisle are large circular expanses of forest, like islands of trees amid plains or hills, giving the continent its name. These groves are ancient and often hold deep magic, with some trees said to be as old as the elves themselves. Many groves are sacred to wood elves, who guard them from outsiders, while others are home to fey creatures, monsters, or hidden ruins. The forests can be disorienting, with paths that seem to shift, and some groves are known to be gateways to other realms. Adventurers might enter a grove seeking rare herbs, only to find themselves lost in a labyrinth of living wood.
At the center of Arborisle, scattered tropical zones break the temperate climate, with steamy jungles, vibrant flora, and exotic beasts. These zones are hot and humid, teeming with life found nowhere else on the continent, from colorful birds to venomous serpents and great cats. The jungles are dangerous and largely unexplored, with ancient ruins and rare resources drawing bold adventurers. Native tribes, some human and some elven, live in these zones, adapted to the harsh conditions. A trek into the tropics might reveal a lost temple, a new species, or a deadly predator hunting the party.
The shores of Arborisle are wet, windy, and cool even in summer, battered by sea breezes and frequent storms. Coastal towns are built to withstand the weather, with sturdy stone houses and harbor walls. Fishing is a major trade, though the waters are also home to dangerous sea creatures, from giant squid to ravenous merfolk. The cliffs and beaches sometimes reveal shipwrecks or tide pools full of unique life. The wind is a constant companion, shaping the culture of the coastal folk, who are hardy and superstitious about the sea.
Beast-kin are humanoids with animal traits—ears, tails, claws, fur, or scales—who are hunted and enslaved across Arborisle. They possess heightened senses and instincts tied to their animal lineage, making them prized for hunting, protection, or exotic companionship. In the eyes of the law, they are property, not people, and their breeding is controlled by slavers to produce desirable traits. Yet despite this oppression, beast-kin retain fierce pride and a deep connection to the wild, which fuels their resistance. Their communities are hidden, mobile, and fiercely protective of their freedom.
The Slavers' Cartel is a loose, brutal network of independent slavers and noble houses that trade in beast-kin, humans, elves, and other humanoids. Anyone deemed unwanted, criminals, and those sold to them. They operate within legal parameters, though they of course stray from the law when they can get away with it. They operate openly in the lowlands and cities, and are the primary existential threat to any free beast-kin. Each type of beast-kin has a specific price and purpose: feline types are prized as exotic companions, avian types used as swift messengers or spies, canine types are loyal guardians, and various 'fertile' types are brutally high-priced for breeders. The Cartel maintains a network of informants, and there are bounties for information leading to the capture of any free beast-kin living outside the legal 'owner' system. Captured beast-kin are typically branded, collared, and sold at public auctions.
Demons are a race of beings from an infernal hellish plane, now permanent denizens of the mortal realm of Arborisle. They display a wide range of appearances: some are small and clawed, others are winged and towering, and many bear horns and jagged features. While their forms vary dramatically, each demon specializes with great efficiency—physical specimens excel in brute strength and combat, while magical ones wield destructive sorcery. They are pragmatic and ruthless, viewing weakness as a flaw to be eliminated. Demons live in hierarchical packs and serve the powerful without question, but betray their masters the moment they sense faltering. Their presence in the southern lands has made the region a place of terror and intrigue, where any stranger could be a demon in disguise or a thrall under their control.
Infernals are the offspring of human and demon unions, a branch of hybrid beings who carry their demon heritage subtly but unmistakably. They possess traits such as slitted eyes, pointed nails, or faint bony ridges resembling horns—enough to mark them as other, but never enough to pass as fully human. Infernals are less physically demonic than their demon parents, yet inherit a share of their efficiency and often display cunning intellect. Because of their visible demonic traits, they are met with immediate ire and wrath from the other humanoids of Arborisle, who treat them as abominations. They rarely venture beyond the southern territory, remaining close to their demonic masters in Ebonmyre, where they serve as intermediaries, laborers, and sometimes enforcers. Their lives are lived under threat from both sides: despised by the north, and barely tolerated by the demons who see them as lesser.
The southern badlands form a desolate, crumbling plateau between the more temperate north and the demon city of Ebonmyre. The ground is dry, cracked, and scattered with ash-like soil; the sky is perpetually hazy, and the air carries a faint sulfurous undertone. It is a place where no honest farmer settles, and where travelers are few. The badlands are home to territorial demon pack animals, scavenging creatures, and hunting parties of demons who patrol the borderlands to keep intruders out. The region is also a graveyard of failed wars: ruined watchtowers and broken siege engines left over from past campaigns against the demon realm. For infernals, the badlands are a buffer, a no-man's-land that keeps them isolated from the north. It is here that any attempt by a northern army would begin, and here that any demonic expedition north would first cross—making the badlands a place of tense silence, broken only by rumors of stirring armies.
Ebonmyre is the demon city at the southern tip of Arborisle, within the southern badlands, a sprawling metropolis of dark stone, black rooftops, and towering ebon spires that claw at the sky. Its streets are paved with obsidian, and its architecture is sharp and angular, built for function as much as intimidation. For a long time, the city lay fairly empty, its demons dormant and its halls echoing with silence. But that has begun to change—rumors spread that a new Demon Lord is rising, and the city slowly stirs to life. The air grows thick with tension, and shadows move in places they once did not. Ebonmyre is the seat of demon power in Arborisle, and whoever claims its throne will command the loyalty of the demon and infernal remnants of the south. For outsiders, Ebonmyre remains a place of almost certain death, but rumors persist of powerful artifacts and forbidden knowledge hidden within its depths.
The Infernal Quarter is a district of Ebonmyre where infernal hybrids dwell, clustered in cramped, time-worn buildings that lean against the black stone walls of the city. It serves as both a living space for hybrids and a labor hub, where demon masters come to assign tasks to their infernal servants. The quarter is a place of contrasts: the sounds of trade and smithing mix with the quiet weeping of those who know no other home. It is here that infernals form their own fragile networks, passing secrets and scraps of news among themselves, dreaming of a future where they might be accepted beyond the southern territory. However, the quarter is also watched closely by demon overseers, and those who speak of rebellion are often made an example of. For an outsider, the Infernal Quarter is the only place in Ebonmyre where a human might be spoken to—if they are brave enough to venture inside.
The Packmoot is an ancient gathering site at the heart of Ebonmyre, a circular plaza ringed by towering ebon pillars etched with runes of binding and dominance. It is here that demon packs come to assert their strength, settle feud disputes, or elect champions to participate in the trials for the Demon Throne. The Moot is a brutal affair: ambitious demons challenge one another with little care for mercy, and the weak are often torn apart before the gathered crowd. Yet the Packmoot is also a place of law—a demon word given at the Moot is considered binding, and even the most treacherous among the hellspawn would think twice before breaking a promise made before the assembled packs. In recent days, the Packmoot has become a stage for the contenders of the Demon Throne to rally support, offering feasts, promises of plunder, and threats of ruin to sway the packs. A visitor might witness the political heart of demondom here, if they live long enough to watch.
The Trial of Embers is the rite by which a demon proves themselves worthy of claiming the Demon Throne. It is an ordeal that combines combat, wit, and a mastery of will, designed to challenge every aspect of a demon's being before the throne itself decides if they are worthy. The trial is held in the Sunken Sanctum beneath Ebonmyre, a forgotten chamber flooded by a pool of molten rock that glows with infernal fire. Over the centuries, many demons have entered the sanctum never to return, their bodies consumed by their own failure. The trial is not a simple duel—it is a series of trials that shift and reshape themselves based on the challenger's strengths and weaknesses, forcing each contender to face the part of themselves they most despise. With the Throne empty, many demons have begun whispering that the Trial of Embers may soon be reopened, and that only a true champion will survive.
The Sundering Pact is the ancient agreement between the demon race and the mortal plane, made when the first demons were cast from their hellish origin into Arborisle. In return for a place to dwell, the demons swore to limit their expansion and to remain in the southern lands unless provoked or summoned. For centuries, these terms were kept—a fragile peace bought at the cost of the demons' pride. The pact is not a physical document but a binding magical oath, etched into the spirits of all demons born on the mortal plane. However, the pact's limits are vague, and many demons interpret its clauses loosely. There are those who believe that a new Demon Lord might find a way to circumvent the pact entirely, breaking the ancient wards and allowing demonkind to range freely across Arborisle. If the pact fails, the north will face an enemy unlike any they have known, and the infernals will be caught in the inevitable war.
Vethra is an infernal merchant and dealmaker who runs a cluttered shop in the shadow of Ebonmyre's outer wall. She appears as a human woman in her forties, with sharp, too-long nails and pupils like vertical slits—the only signs of her heritage. Vethra is a fixer: she knows who to bribe, what to barter, and how to make problems disappear for the right price. She is loyal to neither demon nor infernal, serving anyone who pays, which makes her a valuable and dangerous contact. Her shop is a front for illicit trade—stolen artifacts, forbidden texts, and secrets that could topple houses. Vethra's true motivation is her hidden wish: to one day see an infernal sit on the Demon Throne, a dream she carefully hides from her demon patrons. She is willing to betray anyone, including her own kind, if it brings her closer to that goal. For travelers in Ebonmyre, Vethra is the safest first ally and the most treacherous last one.
