Harpies of the Byeshk Mountains
The voice that can kill you is the same voice that sings the shift change, calls the hour, and brings an entire tavern to tears — the only difference is intent
Origins & History
The harpies have lived in the Byeshk Mountains since before anyone thought to write down how long that has been. They are not immigrants, not refugees, not a displaced people — the mountains are theirs, have always been theirs, and the harpies' relationship with their homeland is so fundamental that their entire culture is built around the acoustics of canyon, cliff face, and open sky. A harpy's voice carries differently in a mountain pass than it does on a flat plain, and the flights of the Byeshk have spent millennia learning how to use the terrain itself as an instrument.
Before the Daughters of Sora Kell arrived, the harpy flights were as fractured as any other Droaamish people — isolated in mountain peaks, endlessly feuding with one another, occasionally swooping down to raid the lowland settlements and retreating before any organised response could form. The harpies were feared by the peoples of the plains and largely irrelevant to the greater politics of the region, because their feuds consumed the energy that might otherwise have made them a power. A flight that spent six months pursuing a vendetta against a rival flight over a nesting dispute had little attention left for empire-building.
The Daughters changed the calculation. Sora Katra's vision of a unified Droaam needed the harpies — specifically, it needed their voices. The Daughters did not conquer the flights; they offered them a role. Several major flights pledged themselves to Droaam: the Stormsinger, the Last Dirge, and the Rotwing all came down from the peaks to "sing Katra's song," embracing the idea that their supernatural voices could serve not just as weapons but as the communication, entertainment, and emotional infrastructure of a new civilisation. Other flights remain independent in the mountains, and the largest of these — the Wind Howlers, led by Callain of the Bloody Word — despises the Daughters and everything they represent. The mountains are contested territory, divided between flights that have bought into Droaam's project and flights that see the Daughters as invaders who have co-opted the harpies' most sacred gift.
Biology & Physiology
Harpies are avian humanoids — bipedal, with a humanoid torso, head, and face, and large feathered wings that serve as both arms and primary locomotion. Their legs end in powerful taloned feet capable of gripping prey, perching on cliff faces, and delivering kicks that can crack bone. A harpy's wingspan is roughly twelve to fourteen feet, and their hollow bones and lean musculature give them a body weight significantly lower than a human of comparable height — a harpy who stands five and a half feet tall may weigh less than eighty pounds. This lightness is essential for flight but makes them physically fragile in close combat; a harpy caught on the ground by a heavier opponent is in serious trouble, and they know it.
Their faces are expressive and roughly humanoid, with sharp features, wide-set eyes adapted for aerial navigation, and mouths that can open wider than a human jaw allows — a structural adaptation for the supernatural vocal range that defines the species. Harpy plumage varies by flight and region: the Stormsingers tend toward dark greys and storm-blues, the Rotwing toward browns and russets, and the Wind Howlers toward stark black and white patterns that are visible at great distances in mountain terrain. Feather patterns serve as flight identification; a harpy's plumage tells other harpies where she comes from before she opens her mouth.
The harpy's vocal apparatus is the most biologically remarkable feature. The harpy larynx is reinforced with cartilage structures that have no analogue in any other humanoid species, allowing the production of sounds across a range of frequencies that extends well above and below human hearing. The supernatural component — the ability to produce effects that compel, terrify, inspire, or soothe — appears to be innate rather than magical in the arcane sense; a harpy in an antimagic field can still produce extraordinary vocal effects, though the most potent supernatural compulsions are suppressed. Harpies can amplify their voices to approximately three times normal volume without apparent strain.
Harpies are omnivorous, with a preference for meat — including carrion, which they consume without ill effect. Their digestive systems are robust, their immune systems formidable, and their tolerance for cold and altitude reflects a species adapted to mountain habitation. They reach maturity around twelve years and live approximately thirty to forty years — a short lifespan by Khorvairian standards, which contributes to the intensity with which harpies experience everything. A creature that lives fast must love fast, hate fast, and sing as though every performance might be the last.
Harpies nest in high places — cliff faces, tower rooftops, mountain ledges — and their nesting instincts are fierce. A harpy defending her nest is more dangerous than a harpy in open combat, because the defence of the nest engages every emotional and supernatural resource the species possesses. Clutches of one to three eggs are typical, and chicks are raised communally within the flight.
The Song
Harpy song is supernatural. This is not a metaphor — the harpy voice operates on frequencies and at intensities that no mundane vocal apparatus can produce, generating effects that bypass the ear and act directly on the mind and the emotions. The "luring song" that the Five Nations associates with harpies — the irresistible call that draws victims to their deaths — is the bluntest and most famous application of this ability, but it is only one note in a range that is, for a skilled songbird, nearly limitless.
A gifted harpy can inspire hope or despair, instil joy or bring tears to the eyes of an audience. She can project her voice at supernatural volume — up to three times louder than a normal shout — making her an ideal town crier, shift-caller, and emergency alert system. She can soothe exhausted workers, calm a brawl before it escalates, modulate a crowd's mood during a public address, and deliver a performance in a tavern that leaves the audience unable to speak for minutes afterward. The songbirds who serve the Daughters in Droaam's cities have turned an evolutionary weapon into a civic tool, and the results are one of the most distinctive features of Droaamish civilisation — the "wide monster" equivalent of a speaking stone network, powered by living voices instead of dragonshards.
But the song is not tame. A harpy who hates you can weave that hatred into a melody that will haunt your dreams. A harpy defending her nest can produce a shriek that ruptures eardrums at close range. A harpy flight attacking in unison — their voices harmonising into a single, layered assault of supernatural compulsion — is one of the most terrifying experiences a soldier can face. The Wind Howlers use their voices as weapons of war, and Callain of the Bloody Word earned her title by singing a rival flight-leader's own warriors into turning on her. The song creates as readily as it destroys.
Cultures & Subgroups
Harpy society is organised into flights — extended kin-groups that occupy specific territories in the Byeshk Mountains and that maintain distinct traditions, artistic styles, and theological interpretations of the Fury. A flight is led by its strongest singer, which is not necessarily its loudest or most combative member — leadership in a harpy flight goes to the voice that can move the most hearts, whether through beauty, terror, or the sheer force of emotion that the song can carry.
The flights that have pledged to Droaam — the Stormsingers, the Last Dirge, the Rotwing, and others — represent roughly half the harpy population. These flights have sent their songbirds into the cities to serve the Daughters' vision: calling shifts, delivering news, entertaining the populace, and providing the emotional scaffolding that holds a chaotic multispecies nation together. The songbirds who serve in Graywall, the Great Crag, and other Droaamish cities are generally more intelligent and disciplined than their mountain-dwelling kin — not because they are a different subspecies, but because the work requires it. A songbird who accidentally lures a street full of goblins to their deaths is a civic disaster, not a successful hunt.
The flights that remain independent — the Wind Howlers chief among them — view the Daughters' Droaam as a betrayal of harpy nature. To the Howlers, the song is not a tool to be deployed in service of goblin work schedules; it is the voice of the Fury herself, the First Song, the sound that Eberron made when she gave birth to the world. Using it to call shift changes and soothe grist-mill workers is blasphemy, and the Howlers' leader, Callain of the Bloody Word, has made her contempt for the arrangement clear to anyone who will listen — and to several who would rather not.
CALLAIN OF THE BLOODY WORD, LEADER OF THE WIND HOWLERS, TO HER FLIGHT "Katra's songbirds preen in their towers and call the hour for goblin labourers. They think this makes them important. They think they are building something. Tell them this: the mountains were ours before the hags came, and the mountains will be ours after the hags fall. The Song does not serve. The Song commands. When the Howl rises, let the lowlanders learn what a harpy's voice was always meant to do."
Religion & Spiritual Life
All harpies claim to sing with the voice of the Fury — the Sovereign of passion, wrath, and uncontrolled emotion — but the Fury is interpreted as differently by the harpy flights as the Horned Prince is by the minotaur clans. The Stormsingers see her as one with the Devourer, song and storm woven together. The Wind Howlers call her the Howl — Eberron's birth-scream, the primal sound that brought the world into being. Other flights know her as the Song, the First Song, or simply the Voice. In all cases, singing is worship — not a ritual performed at appointed times, but a constant, joyful, furious communion with the divine. A harpy who sings well is praying. A harpy who sings badly is in spiritual crisis.
Within the broader Cazhaak faith that serves as Droaam's state religion, the Fury is one of the Dark Six, and medusa Voices of the Shadow serve as spiritual authorities across many Droaamish communities. Harpies generally respect the Cazhaak priests — they are allies, and the Fury is honoured within the Cazhaak framework — but a harpy's relationship with the Fury is personal, immediate, and expressed through song rather than through the structured rituals of the medusa priesthood. A harpy does not need a priest to commune with the Fury. She needs only her voice.
Life in the Five Nations
Harpies have established a modest but growing presence in the Five Nations through House Tharashk's brokering services. Harpy couriers operate in Sharn and a few other major cities, offering aerial delivery that is faster than foot courier and more personalised than gargoyle service — though Tharashk's advertisements carefully note that "emotional effects experienced during delivery" are not the house's responsibility. In Sharn, harpy couriers navigate the vertical cityscape with ease, and their services are in growing demand among the middle and upper wards.
The reception is mixed. A harpy singing on a street corner in Sharn's entertainment district can draw a crowd and fill a hat with coins — her voice is genuinely, heartbreakingly beautiful, and audiences who came expecting a monster discover an artist. A harpy singing in Thrane provokes a very different reaction, because the Silver Flame's theology classifies supernatural vocal compulsion as a form of enchantment and enchantment as a tool of evil. The Thranish response to harpies is not persecution — it is wariness, the specific anxiety of people who know that the beautiful voice they are hearing has the biological capacity to override their free will.
Among the Five Nations populations who have no direct experience of harpies, the stereotype is simple and lethal: harpies lure you with their voices and kill you when you come close. This is not wrong — feral harpies in the wild absolutely do this — but it is as incomplete as describing humans as "creatures that start wars and burn cities." The songbirds of Droaam are a different proposition, and the gap between the stereotype and the reality is a source of both opportunity and tension for harpies who venture east.

Relations & Perceptions
Within Droaam, the songbirds are valued, celebrated, and slightly feared — which is approximately how the harpies prefer it. A songbird who calls the shift at a grist mill is performing a civic function, but she is also demonstrating, every single day, that her voice has the power to move hundreds of people at once. The fact that she uses it to summon workers rather than to lure them off a cliff is a choice, and everyone within earshot knows it. This gives the songbirds a subtle authority that transcends their formal position in Droaam's hierarchy — they are not warlords, not priests, not politicians, but they are the people whose voices hold the emotional fabric of the cities together, and nobody wants to be the person who makes a songbird angry.
The independent flights — the Wind Howlers and their allies — are a genuine threat that the Daughters take seriously. Callain of the Bloody Word commands the largest independent harpy force in the mountains, and her opposition to Droaam is ideological, not mercenary; she believes the Daughters have corrupted the Song, and she will not be bought off. If Callain unites the independent flights into a coordinated force, the Daughters will have an insurgency in their mountains — and an insurgency conducted by creatures who can fly, who can compel obedience with their voices, and who know every canyon and cliff face in the Byeshk is not an insurgency that can be suppressed with ogre brute squads.
FROM THE STREET OF SHADOWS, GRAYWALL — A SONGBIRD CALLS THE THIRD SHIFT The sound begins as a single note, low and warm, rising from the tower above the grist mill like heat from a forge. It climbs through registers no human throat could reach, curving into a melody that makes the goblins on the departing shift slow their steps and the ogres on the arriving shift straighten their shoulders. The note holds — impossibly long, impossibly clear — and then breaks into a cascade of harmonics that fills the street from wall to wall. The workers move. Some are smiling. Some have tears on their cheeks. The harpy on the tower folds her wings, satisfied. This is what she was born to do, and she will do it again in eight hours, and it will be just as beautiful, because for a harpy, beauty is the point.
Hooks & Tensions
The harpy tension is between art and utility — between the Song as sacred expression and the Song as civic infrastructure.
The songbirds who serve in Droaam's cities have found something remarkable: a place in a civilisation that values what they do, that treats their supernatural voices as gifts rather than threats, and that pays them to do the thing they love most in the world. This is genuinely new. For all of harpy history, the voice was a weapon or a sacred mystery — never a job, never a profession, never something you did for eight hours and then went home. The Daughters' Droaam has given the harpies something they never had before: a civic identity. The question is whether that identity is a liberation or a domestication.
The Wind Howlers say it is domestication — that the songbirds have traded their freedom for a tower and a schedule, that the Song was never meant to call goblins to their shifts, and that Sora Katra is using the harpy voice the way House Lyrandar uses an elemental: a natural force chained to serve someone else's purpose. The songbirds reply that the Howlers are romanticising savagery, that endless mountain feuds and raiding lowland caravans were not freedom but futility, and that using your voice to build a nation is more worthy than using it to lure strangers off a cliff.
