![[Yan-C-Bin.png|400]] **Archomental, Prince of Evil Air Creatures** **Alignment:** Neutral Evil **Home Plane:** Elemental Plane of Air **Realm:** The Palace of Solid Air **Also Known As:** Prince of Evil Aerial Creatures, Master of Evil Air, the Great Cloud, the Shadow of the Four Winds, the Howling Hatred ### Overview Yan-C-Bin, the Prince of Evil Air Creatures, is an ancient and immensely powerful archomental who embodies the destructive and merciless aspects of elemental air. As one of the Princes of Elemental Evil, he commands supernatural winds, violent storms, and numerous creatures associated with the skies. While Akadi represents the broader elemental power of air, Yan-C-Bin personifies its capacity to devastate the world through hurricanes, tornadoes, lightning, and the suffocating absence of breath. His ultimate ambition is to establish air as the supreme elemental force, destroying the works of civilisation and extending his influence throughout the multiverse. Yan-C-Bin's natural form is an invisible, swirling vortex of elemental air. He can manifest as an amorphous cloud approximately ten feet across, occasionally revealing two luminous eyes within his otherwise indistinct body. His presence may be detected only through a sudden disturbance in the air, an unnatural gust, or the movement of objects around him. He can also assume humanoid appearances, including that of a tall, elderly sage with flowing white hair and a body that dissolves into mist. Certain accounts describe this manifestation as possessing three pairs of birdlike wings, while others depict him as a gaunt, dark-skinned man with pale, glowing eyes and winds constantly stirring around his robes. Despite his association with violent storms, Yan-C-Bin is not governed entirely by uncontrolled fury. He possesses considerable intelligence, wisdom, and a strong interest in knowledge. He prefers to study potential enemies, gather information, and understand their weaknesses before acting against them. His temperament can change rapidly, however, and his apparent patience may give way to sudden destructive violence. He combines careful observation with swift and unexpected attacks, making him particularly dangerous to opponents who mistake his invisibility or silence for inactivity. Yan-C-Bin is also distinguished by his peculiar sense of honour. Although malevolent and capable of extraordinary cruelty, he has been known to reward creatures that provide valuable assistance. Such generosity does not make him trustworthy, for he remains committed to the supremacy of elemental air and the destruction of those who obstruct his ambitions. Among the great evil archomentals, Yan-C-Bin is regarded as one of the youngest, although his existence reaches back into the earliest ages of the multiverse. His influence extends across the Elemental Plane of Air and into the Material Plane, where evil aerial creatures and mortal cultists revere him as a god. Like the other elemental princes, however, he is not a true deity. His power derives from his extraordinary elemental nature and his command over the destructive forces of air. ### Domain and Influence Yan-C-Bin resides within the Elemental Plane of Air, an immense realm of open skies, powerful winds, drifting clouds, and floating islands of solid matter. Unlike the enclosed expanses of elemental earth or the endless depths of elemental water, this plane possesses no universal surface or fixed horizon. Its inhabitants travel through an apparently limitless expanse of air, where settlements, fortresses, and islands may drift upon great currents. His principal residence is an extraordinary palace constructed from solidified air. The fortress floats within the Plane of Air, surrounded by great spiked spheres of glass that slowly revolve around it. As the spheres move, they produce delicate chiming sounds that carry through the surrounding winds. The palace itself is difficult to perceive, and its unusual construction makes it unlike the conventional strongholds of most other elemental princes. Although Yan-C-Bin possesses this magnificent residence, he spends considerable time wandering the planes rather than remaining within its walls. His travels are often undertaken in secrecy, allowing him to observe the activities of rivals, investigate their servants, and gather information without revealing his presence. He is especially interested in discovering the weaknesses of those who might oppose his ambitions. The region surrounding his palace contains the remains of elemental territories once occupied by intruders and settlers. These ruined pockets have acquired a reputation for containing abandoned treasures and forgotten knowledge. Yan-C-Bin's servants and champions guard the area, discouraging those who might seek to investigate its contents or establish new holdings near his domain. Yan-C-Bin exercises authority over numerous creatures associated with elemental air. His servants include air elementals, invisible stalkers, aerial servants, air grues, phiuhls, breathdrinkers, arrowhawks, and other dangerous inhabitants of the skies. He has also maintained dealings with nerras, mysterious beings associated with mirrors and reflections. Despite these connections, his power does not extend over every creature inhabiting the Plane of Air. Unlike Imix and Ogrémoch, Yan-C-Bin does not devote most of his attention to assembling enormous armies or directly administering conquered territories. He prefers secrecy, intelligence gathering, and the manipulation of circumstances to his advantage. His servants provide information and carry out his intentions, while his own ability to travel unseen allows him to intervene when necessary. One of his longstanding enemies is Ogrémoch, the Prince of Evil Earth Creatures. Their rivalry arises from the opposing natures of their elements, with Yan-C-Bin seeking the supremacy of air over the earth that resists its passage. Although the two archomentals remain enemies, their hostility is generally less intense than the hatred between Imix and Olhydra. His greatest rival is Chan, the Princess of Good Air Creatures. Chan represents the benevolent aspects of elemental air, including gentle winds and the peaceful movement of the skies. She opposes Yan-C-Bin's destructive ambitions and watches his activities closely. Their conflict is conducted primarily through observation, interference, and the gathering of information rather than open warfare. Both are aware of the other's influence, and each attempts to prevent the other from gaining a decisive advantage. Yan-C-Bin also despises the djinn, whose independent societies and considerable power occupy important regions of the Plane of Air. Their settlements and rulers remain beyond his authority, while his rivalry with the demon lord Pazuzu occasionally brings him into conflict with another ancient power associated with the skies. Despite his considerable influence, Yan-C-Bin has not established dominion over the entire Plane of Air. The djinn, Chan, and numerous independent inhabitants maintain their own territories and interests. His ultimate ambition is therefore far greater than his present authority, for he seeks not merely to control his native plane but to demonstrate the supremacy of elemental air throughout existence. ### Symbols and Icons  Yan-C-Bin's personal symbol is a silver-white circle, an emblem associated with the Prince of Evil Air Creatures and his authority over elemental wind. The Cult of the Howling Hatred employs a separate symbol representing elemental air. This emblem consists of an inverted triangle with three branching lines rising above it. Different interpretations exist among the cult's members. Some regard the image as the funnel of a tornado, while others believe it represents the superiority of flying creatures over those confined to the ground. Certain followers maintain that the symbol is an ancient rune associated directly with Yan-C-Bin. Members of the Howling Hatred also recognise one another through a distinctive hand sign. By bringing the thumbs and little fingers together while curling the remaining fingers into fists, a cultist forms an inverted triangular shape. This gesture serves as a discreet means of identifying allegiance to the cult. The silver-white circle remains Yan-C-Bin's established personal emblem, while the inverted triangle is particularly associated with the worship of elemental air among the Howling Hatred. ### Worship and Tributes Yan-C-Bin receives worship from evil aerial creatures and mortals who seek power through the manipulation of wind, storms, and elemental air. His followers include cloud giants, certain practitioners of martial and mystical traditions, and individuals whose lives are closely associated with flight. Dervishes, swashbucklers, and riders of powerful aerial creatures have also been known to revere him. Among his more organised mortal followers are a clan of ninjas and an order of monks and shugenja devoted to his power. These traditions reflect his association with secrecy, agility, and supernatural control over air. His worship is not limited to creatures possessing natural flight, for those who value deception, speed, and the ability to strike without warning may also seek his patronage. The Cult of the Howling Hatred represents one of the most dangerous mortal organisations dedicated to Yan-C-Bin. Its followers believe that elemental air grants them the means to escape restrictions, overcome enemies, and claim whatever they believe has been unjustly denied to them. Unlike cults devoted entirely to destruction for its own sake, many followers of the Howling Hatred view elemental power as an instrument for achieving personal ambitions. Illusionists, spies, assassins, and other individuals who rely upon deception are particularly attracted to the cult. Its members regard themselves as more intelligent, resourceful, and capable than ordinary people. They favour secrecy and indirect methods over open confrontation, believing that subtle action can achieve victories that would otherwise require considerable force. The cult's practices include: - **Sacrifices from Great Heights:** Followers of the Howling Hatred have been known to sacrifice enemies by casting them from high places. At Feathergale Spire, victims are marked with the symbol of elemental air before being thrown from the tower's pinnacle into the valley below. - **Sacrifices to the Whirlwind:** Within the Howling Caves, cultists cast victims into a shaft occupied by a bound air elemental. The creature's violent winds tear apart those sacrificed, while the surrounding chambers bear the remains of the dead. - **Devotion Through Flight:** Members of the cult value the ability to fly and seek magical means of taking to the skies. Hippogriffs, griffons, and giant vultures are commonly employed as mounts, while certain followers use enchanted garments and devices that allow them to move through the air. - **Deception and Infiltration:** Cultists demonstrate their allegiance by employing stealth, illusion, and carefully planned ambushes. Their activities frequently involve gathering information, manipulating enemies, and exploiting vulnerabilities before launching attacks. - **The Calling of Destructive Storms:** Powerful members of the cult seek to unleash cyclones and violent winds upon settlements. Their use of elemental devastation reflects the destructive ambitions of Yan-C-Bin and their belief that the power of air should overcome the works of civilisation. - **Ascetic Devotion to Air:** Certain fanatical priests attempt to sustain themselves upon air alone. Prolonged adherence to this practice leaves their bodies severely emaciated, although their supernatural connection to elemental air allows them to endure conditions that would ordinarily prove fatal. Although Yan-C-Bin receives worship, he has little interest in the personal devotion of his followers. He does not value offerings or sacrifices for their own sake and shows little concern for whether mortals honour him. His primary interest remains the destruction of the Material Plane through the overwhelming power of elemental air. ### Clergy and Temples The clergy of Yan-C-Bin includes priests, monks, shugenja, and other spellcasters who seek supernatural power through elemental air. His religious following exists among several different peoples and traditions, including communities associated with cloud giants and those who rely upon aerial travel. Certain clerics wear robes trimmed with white, distinguishing their religious allegiance through clothing associated with the element they serve. Their temples are frequently established upon high mountain peaks and other elevated locations where powerful winds provide a suitable environment for worship. Such sanctuaries may be occupied by cloud giants, harpies, renegade djinn, and humanoids mounted upon hippogriffs, griffons, or rocs. Their elevated positions make them difficult to approach without magical assistance or the ability to fly. Yan-C-Bin's influence is particularly strong among the Cult of the Howling Hatred, which established an extensive network of strongholds in the Dessarin Valley of Faerûn. The cult was led by Aerisi Kalinoth, a moon elf who proclaimed herself the Prophet of Air and gathered followers through enchantment, manipulation, and her connection to the Prince of Evil Air. Aerisi was born Dara Algwynenn Kalinoth and raised within an enchanted castle in a remote region of Faerie. Her parents sheltered her from the difficulties of the wider world, allowing her to pursue studies of magic and indulge her fascination with the avariel, the winged elves of ancient tales. When she was eventually brought to Evereska, Aerisi discovered that other moon elves did not readily submit to her demands. Her frustration developed into an obsession with freedom, personal power, and the ability to punish those who offended her. During this period, she began experiencing dreams of an elderly mystic with brown skin and white hair who promised to teach her the secrets of elemental air. The mysterious figure was Yan-C-Bin. Guided by these visions, Aerisi devoted herself to elemental magic and eventually departed Evereska. Her dreams led her beneath the Sumber Hills, where she discovered Windvane, an enchanted spear containing a fragment of Yan-C-Bin's elemental essence. Possession of the weapon strengthened her connection to the Prince of Evil Air and provided the foundation upon which she established the Howling Hatred. Aerisi's followers regarded her as both prophet and queen. She maintained a court filled with musicians, attendants, and warriors mounted upon flying creatures. Through illusion magic, she fashioned the appearance of feathered wings upon her back, presenting herself as an avariel despite possessing no natural wings. The cult established its principal temple within the ancient dwarven city of Tyar-Besil, beneath the Sumber Hills. Its sanctuary occupied the southwestern quarter of the ruined city, where the dwarves had once constructed a great palace beside an immense subterranean chasm. The Temple of Howling Hatred contained spacious plazas, towering monuments, elevated chambers, and magical currents of air that allowed its inhabitants to travel through the complex. Aerisi established her court within the former royal chambers, where her followers gathered to receive orders and offer devotion to their elemental patron. At the surface, the cult maintained a concealed alliance with the Feathergale Society, a group of Waterdhavian nobles and aerial-mount enthusiasts who occupied Feathergale Spire in the Sighing Valley. Their leader, Thurl Merosska, commanded the Feathergale Knights, who secretly worshipped Yan-C-Bin and served as scouts, spies, messengers, and aerial warriors for the Howling Hatred. Beneath the temple, the cult controlled the Howling Caves, an extensive network of wind-filled caverns containing a powerful elemental air node. These chambers housed the portal through which Aerisi intended to summon Yan-C-Bin into Faerûn. ### Powers and Abilities Yan-C-Bin possesses immense supernatural command over air, wind, lightning, and thunder. His elemental nature allows him to move through spaces inaccessible to ordinary creatures, manipulate the surrounding atmosphere, and inflict devastating injuries through the force of his winds. His abilities make him especially dangerous within open skies, elevated terrain, and regions connected directly to the Elemental Plane of Air. - **Elemental Air Form:** Yan-C-Bin's natural body is composed of invisible, swirling air. He can pass through extremely narrow openings and move through spaces occupied by other creatures, provided that air can flow through them. This allows him to bypass many physical obstacles that would prevent the movement of a solid being. - **Control of Wind:** Yan-C-Bin can create powerful gusts capable of pushing creatures and objects away from him. His mastery extends from concentrated bursts of air to immense atmospheric disturbances capable of devastating large areas. - **Whirlwind Transformation:** Yan-C-Bin can assume the form of a violent whirlwind, drawing creatures into its destructive currents. This manifestation allows him to overwhelm enemies through the combined force of powerful winds and airborne debris. - **Lightning Magic:** Yan-C-Bin can unleash powerful bolts of lightning and cause electrical energy to leap between multiple enemies. His command of storms allows him to inflict considerable destruction even upon opponents positioned beyond the reach of his physical form. - **Thunderous Force:** Yan-C-Bin can generate immense bursts of thunder capable of injuring and deafening nearby creatures. These eruptions are powerful enough to affect enemies across a considerable area, demonstrating his command over the violent movement of air. - **Suffocation:** One of Yan-C-Bin's most dangerous powers is his ability to remove the air from a living creature's lungs. Victims subjected to this attack may be rendered incapable of breathing or speaking, and the loss of breath can bring them to the brink of death. - **Poisonous Clouds:** Yan-C-Bin can produce clouds of poisonous vapour capable of harming living creatures. His control over the atmosphere allows him to employ toxic air as another means of overcoming enemies. - **Invisibility:** Yan-C-Bin can become invisible through his command of elemental air. His natural form is already difficult to perceive, and his magical abilities allow him to conceal his presence while observing enemies or preparing an attack. - **Humanoid Transformation:** Yan-C-Bin can assume the appearance of a humanoid, although a faint swirling breeze continues to surround him. His eyes retain an unnatural quality, often appearing pale, cloudy, or illuminated by elemental power. This transformation allows him to interact with creatures who might otherwise struggle to perceive his true form. - **Summoning Air Elementals:** Yan-C-Bin can summon powerful air elementals to serve him. His authority over these creatures allows him to call upon reinforcements without relying entirely upon servants already present within his domain. - **Command Over Aerial Creatures:** Yan-C-Bin has the power to summon or command creatures associated with elemental air, including invisible stalkers, aerial servants, and cloud giants. His influence can also corrupt certain elemental beings, turning them toward evil. - **Supernatural Speed:** Yan-C-Bin possesses extraordinary mobility, particularly while travelling through the air. His speed and ability to teleport allow him to reposition himself rapidly, making him difficult to surround or confine. - **Magical Resilience:** Yan-C-Bin possesses considerable resistance to physical injury and hostile magic. His elemental nature renders lightning, thunder, and poison ineffective against him, while many forms of ordinary weaponry are unable to injure him significantly. - **Control of Atmospheric Temperature:** Within his palace or a powerful elemental air node, Yan-C-Bin can cause sudden changes in temperature, producing freezing sleet or intense heat. Such disturbances can transform the surrounding environment and expose enemies to dangerous conditions. - **Manipulation of Airborne Objects:** Yan-C-Bin can lift creatures and objects into the air, carrying them upon violent currents before hurling them against nearby surfaces or allowing them to fall. This ability makes enclosed caverns and elevated locations particularly dangerous when he is present. - **Mastery of Elemental Air Nodes:** Within a region strongly connected to the Elemental Plane of Air, Yan-C-Bin can cause thunderstorms, violent winds, and destructive cyclones. His influence can transform the surrounding countryside and establish temporary passages through which elemental creatures enter the Material Plane. Yan-C-Bin's extraordinary mobility and command over the atmosphere make him difficult to confront directly. His ability to remain unseen, strike from a distance, and control the surrounding terrain allows him to overwhelm enemies who cannot match his freedom of movement. ### Treatment of the Chosen and Faithful Yan-C-Bin regards most mortal creatures with indifference, showing little interest in their personal devotion or religious observances. His principal concern is the destruction of the Material Plane and the establishment of elemental air as the supreme force in existence. Followers who worship him in the expectation of personal attention may therefore receive little acknowledgement, regardless of their sacrifices. Nevertheless, Yan-C-Bin possesses a distinctive sense of honour and has been known to reward individuals who provide valuable assistance. His willingness to recognise useful service distinguishes him from certain other elemental princes, although such rewards do not imply benevolence or lasting loyalty toward those who receive them. His servants may obtain considerable power through elemental magic, particularly when they gain access to artifacts or locations infused with his essence. Such power can allow mortals to fly, become invisible, manipulate lightning, or command lesser air elementals. Aerisi Kalinoth is among the most prominent known mortals to receive power associated with Yan-C-Bin. Through her possession of Windvane, she gained the authority and magical strength necessary to lead the Cult of the Howling Hatred. Her connection to the archomental also brought visions that influenced her ambitions and encouraged her belief that she was destined to rule others. The practices of Aerisi's cult demonstrate the dangers associated with such devotion. Ordinary followers are frequently treated as expendable servants, while those who displease their superiors may suffer imprisonment, magical punishment, or death. Aerisi herself considers her followers subjects of her court rather than equals, and her demands for obedience frequently place them in mortal danger. The priests of the Howling Hatred have also subjected themselves to extreme deprivation in pursuit of greater closeness to their element. Certain fanatics attempt to survive upon air alone, leaving their bodies severely wasted. Such practices demonstrate the lengths to which followers may go in pursuit of elemental power, although Yan-C-Bin himself shows little concern for their suffering. Yan-C-Bin's treatment of his faithful is therefore governed primarily by their usefulness. He may reward extraordinary service, but he does not require worship for its own sake and remains willing to destroy those whose actions interfere with his ambitions. ### Myths and Legends Yan-C-Bin's ancient history is closely associated with the conflicts of the elemental princes, the struggle between Law and Chaos, and the influence of the Elder Elemental Eye. His secretive nature has left considerable uncertainty surrounding some of his activities, while his relationships with other planar powers have shaped his enduring ambitions. - **The Elder Elemental Eye:** Yan-C-Bin is associated with the mysterious Elder Elemental Eye, an ancient force connected to the Princes of Elemental Evil. The precise nature of this relationship remains uncertain. Some sages believe that the elemental princes were corrupted or created through the influence of this power, while others regard the Eye as a common force binding their destinies together. Its association with Tharizdun has also raised questions about the extent to which Yan-C-Bin and the other archomentals have been manipulated by powers beyond their understanding. - **The Youngest Prince:** Yan-C-Bin is traditionally regarded as the youngest of the great Princes of Elemental Evil. Despite this distinction, he is an extraordinarily ancient being whose existence reaches back into the earliest conflicts of the planes. His relative youth has never prevented him from becoming one of the most formidable elemental powers. - **The War Between Law and Chaos:** During the ancient war between the Wind Dukes of Aaqa and the Queen of Chaos, Yan-C-Bin aligned himself with the forces of Law. His participation placed him among the powers opposing the Queen of Chaos and her demonic allies. His involvement in this conflict also contributed to the longstanding hostility between himself and Ogrémoch, who fought on the opposing side. - **The Rivalry with Ogrémoch:** Yan-C-Bin's enmity with Ogrémoch reflects the fundamental opposition between Air and Earth. Both seek the supremacy of their respective elements, and each considers the other's ambitions an obstacle. Their rivalry has endured across the ages, although neither has succeeded in destroying the other. - **The Secret War with Chan:** Chan, the Princess of Good Air Creatures, is Yan-C-Bin's greatest enemy. Their conflict is distinguished by secrecy rather than open warfare, with both employing observation, information gathering, and interference to frustrate the other's plans. Ancient accounts maintain that the two have not met in direct battle, although each understands the danger posed by the other. Their rivalry remains unresolved. - **The Hostility Toward Pazuzu:** Yan-C-Bin has occasionally come into conflict with Pazuzu, the demon lord associated with evil aerial creatures and the skies above the Abyss. Their interests overlap through their influence over flying beings, although neither possesses complete authority over the creatures claimed by the other. - **The Palace of Solid Air:** Yan-C-Bin's unusual palace is constructed from air rendered solid through supernatural means. Great spiked glass spheres surround the fortress, turning slowly and producing chiming sounds. The surrounding region contains the remnants of territories destroyed by the archomental's forces, and rumours persist that considerable wealth and forgotten knowledge remain concealed among the ruins. - **The Tempestcutter:** Yan-C-Bin has been associated with a magical short sword known as the tempestcutter. The weapon can render its wielder invisible and provide protection against attacks associated with elemental air. Such weapons have been offered to particularly useful servants, demonstrating that the archomental may reward those who advance his interests. - **The Temple of Elemental Evil:** Yan-C-Bin has been associated with the schemes of the Temple of Elemental Evil upon Oerth. His connection to the Elder Elemental Eye brought his destructive elemental power into the wider ambitions of the temple's servants. Through such organisations, the influence of the elemental princes has threatened the Material Plane on several occasions. - **The Visions of Aerisi Kalinoth:** Yan-C-Bin appeared to Aerisi Kalinoth in dreams as an elderly mystic with brown skin and white hair. These visions encouraged her to abandon the restrictions of elven society and devote herself to elemental air. Her discovery of Windvane subsequently established her as the Prophet of Air and allowed her to create a powerful cult devoted to Yan-C-Bin. - **The Spear Windvane:** Windvane is a magical spear containing a fragment of Yan-C-Bin's elemental essence. The weapon grants its wielder powers associated with elemental air and serves as the key to opening or closing a great portal connecting the Material Plane to the Elemental Plane of Air. In the possession of Aerisi Kalinoth, Windvane became the principal instrument through which the Howling Hatred sought to summon its patron into Faerûn. - **The Destruction of the Deep Gnome Outpost:** Beneath the Sumber Hills, a community of deep gnomes attempted to resist the Cult of the Howling Hatred after the cult seized nearby caverns. Aerisi employed a devastating orb of elemental air against their settlement, unleashing a cyclone that obliterated the outpost. The magical destruction permanently altered the surrounding caverns, filling them with unnatural winds and contributing to the creation of a powerful elemental air node. - **The Howling Caves:** Deep beneath Tyar-Besil lies a system of caverns containing a portal to the Elemental Plane of Air. The portal manifests within a violent thundercloud suspended between enormous stone formations. Through the power of Windvane and the appropriate ritual, Yan-C-Bin may cross this passage and enter the Material Plane. ### Encounters with Yan-C-Bin's Influence Yan-C-Bin's influence is encountered throughout the Elemental Plane of Air and wherever destructive winds or mortal cults seek to extend his authority. His servants, magical artifacts, and elemental portals create dangers in both the open skies and the subterranean regions where his followers establish their sanctuaries. - **The Palace of Solid Air:** Yan-C-Bin's principal residence floats within the Elemental Plane of Air, surrounded by rotating spiked glass spheres. The fortress is difficult to perceive and protected by elemental servants and other guardians. Its surroundings contain the remains of destroyed settlements and territories, where abandoned treasure and forgotten knowledge may still be found. - **The Servants of Evil Air:** Air elementals, invisible stalkers, aerial servants, air grues, and other flying or air-associated creatures serve Yan-C-Bin. Such beings may carry out his instructions, gather information, or guard locations important to his ambitions. - **Temples Upon Mountain Peaks:** Yan-C-Bin's worshippers establish religious sanctuaries upon high mountains and other elevated sites. These places may shelter cloud giants, harpies, renegade djinn, and mortals mounted upon powerful aerial creatures. Their isolation and difficult approaches provide natural protection against intrusion. - **The Cult of the Howling Hatred:** Mortal followers of Yan-C-Bin employ illusion, stealth, infiltration, and magical flight to pursue their objectives. They frequently rely upon spies and assassins rather than direct military confrontation, while their strongest members wield destructive wind and lightning magic. - **Feathergale Spire:** The Feathergale Society occupies a tall fortress overlooking the Sighing Valley. Although its members present themselves as noble enthusiasts of aerial travel, the Feathergale Knights secretly serve Yan-C-Bin. Their riders patrol the surrounding region, gather information, and carry out attacks against those who threaten the cult. - **The Feathergale Sacrifices:** At the pinnacle of Feathergale Spire, the knights maintain a shrine dedicated to elemental evil. Victims are marked with the symbol of air before being thrown from the tower. The bodies fall into the Sighing Valley, where scavenging creatures remove much of the evidence. - **The Temple of Howling Hatred:** Beneath the Sumber Hills, the cult occupies a former dwarven palace within the ruins of Tyar-Besil. Its halls contain priests, aerial warriors, kenku, powerful spellcasters, and summoned creatures. Magical currents move through the chambers, while an immense chasm provides access to the deeper elemental node. - **The Court of Aerisi Kalinoth:** The Prophet of Air maintains a court within the underground temple, surrounded by musicians, attendants, and warriors loyal to her. Her followers regard her as a queen, while she employs powerful enchantments and the magic of Windvane to maintain her authority. - **The Howling Caves:** The caverns beneath the temple are filled with unnatural winds, powerful air currents, and the remains of sacrifices. Harpies, elemental guardians, and fanatical priests protect the approaches to the portal connecting the Material Plane with Yan-C-Bin's home plane. - **The Elemental Air Portal:** At the heart of the Howling Caves lies a portal surrounded by thunder and lightning. It connects directly to the steps of Yan-C-Bin's invisible fortress. When the proper ritual is performed, the Prince of Evil Air can enter Faerûn through this passage. The destruction of Windvane within the portal can close the connection and force Yan-C-Bin back to his native plane. - **Regions of Elemental Devastation:** Where Yan-C-Bin establishes a powerful presence within an elemental air node, the surrounding environment becomes increasingly dangerous. Gale-force winds tear across the landscape, thunderstorms erupt with unnatural frequency, and cyclones destroy buildings and vegetation. Temperatures fluctuate between intense heat and freezing cold, while temporary portals may allow elemental creatures to enter the Material Plane. ### Conclusion Yan-C-Bin is one of the most formidable archomentals of the Inner Planes, commanding the destructive forces of elemental air and numerous creatures associated with the skies. His invisible form, extraordinary mobility, and mastery of storms distinguish him from the other Princes of Elemental Evil, while his intelligence and preference for secrecy make him particularly difficult to oppose. His enduring rivalries with Chan and Ogrémoch, his hostility toward Pazuzu and the djinn, and his association with the Elder Elemental Eye have involved him in conflicts extending across the planes. Although he possesses considerable power, his authority over the Elemental Plane of Air remains incomplete, with numerous independent beings and societies continuing to resist his ambitions. Through mortal organisations such as the Cult of the Howling Hatred, Yan-C-Bin has extended his influence into Faerûn, where his followers have attempted to summon him through powerful elemental portals. His worshippers may seek freedom, personal power, or revenge, but their patron remains largely indifferent to their individual desires. Yan-C-Bin's ultimate objective is the annihilation of the Material Plane beneath the overwhelming force of elemental air, leaving the existing world shattered by storms and the destructive supremacy of wind.
