Kolju-taat

Tradition / Region: Estonian Mythology
Alternative names: Skull Grandfather
Category: Cow, Demon

The Myth

Kolju-taat is a guardian spirit of the sea from the coast of northern Estonia. He is especially associated with the waters near Keila-Joa and appears either as a huge bull rising from the sea or as a tall old man with a strangely shaped skull, traveling in a silver-white boat.

Although generally feared, Kolju-taat was not always hostile. He could both harm and help fishermen. It was believed that anyone who failed to offer him a sacrifice would be punished. Fish, alcohol, salt, and bread were commonly offered, often by throwing them directly into the sea. After returning home, fishermen also shared part of their catch with the poor, believing this would ensure a rich catch in the future.

Gul-yabani

by

Tradition / Region: Turkish, Azerbaijani, Kyrgyz and Tajik folklore
Alternative names: Gul, Ghul, Desert Demon
Category: Demon, Zombie

The Myth

The Gul-yabani is a fearsome spirit of the wild places, known throughout parts of Central Asia and the Turkic world. Its name means “Desert Demon,” and it is regarded as a dangerous being that inhabits lonely steppes, cemeteries, deserts, forests, and remote mountains. Travelers who encounter it after sunset are said to face terror or death.

The creature is usually described as gigantic, standing three to four meters tall and covered in gray or black fur. It possesses an overpowering animal-like stench, backward-facing feet or clawed limbs, and often appears in the form of an enormous shepherd or hairy man. Its arrival is accompanied by shrill whistling in the darkness.

Among Turks and Azerbaijanis, Gul-yabani wanders cemeteries and desolate places at night. It frightens travelers and is especially known for riding horses, tangling their manes before vanishing into the darkness. In some parts of western Azerbaijan it was even identified with harmful water spirits. It was believed that if a Gul-yabani could be captured and pierced with a needle, it would become bound to its captor and perform work for them, although often doing the opposite of what was intended.

The Kyrgyz of the Eastern Pamirs and the Tajiks believed the creature lived in deserts and mountain forests. Although monstrous in appearance, it speaks with a human voice and often challenges strong men to wrestling matches. Only exceptionally powerful individuals are capable of fighting it as an equal.

Stories tell of a man near Tajikabad who encountered a giant shepherd after sunset. The two wrestled throughout the night, neither able to defeat the other. When dawn arrived, the stranger was revealed to be covered in wool. The creature gifted the man a piece of its fur and promised friendship, telling him that burning the hair would summon it. A mullah later explained that the mysterious shepherd had been a Gul-yabani and warned that revealing the encounter could bring death.

The Gul-yabani is said to understand every language, though it communicates through thoughts rather than spoken words. Those who establish contact with it may gain unusual powers, and only extremely pious mullahs are believed capable of seeing the creature clearly.

Hunters seldom encounter Gul-yabani because the monster greatly fears gunfire and can smell gunpowder from many kilometers away. One story tells of a police chief resting beside his car in the mountains when a tremendous force began shaking the vehicle. Looking outside, he saw an enormous hairy being devouring meat from a basin. The creature pressed its giant hands against the rear window of the car before fleeing when the officer fired his pistol. Two massive handprints were said to remain on the glass.

Mysterious, foul-smelling, and immensely powerful, the Gul-yabani is remembered as one of the great monsters of Turkic folklore—a giant hairy demon that roams the lonely wilderness and appears only when night falls.

Baubas

by

Tradition / Region: Lithuanian Mythology
Alternative names: None commonly recorded
Category: Demon

The Myth

The Baubas is a sinister spirit feared throughout Lithuanian folklore. It is said to lurk in dark corners of houses, beneath carpets, under beds, or anywhere shadows gather. Children were taught to fear it, and parents often warned that the Baubas would come for those who misbehaved.

The creature is described as dark or black in color, with glowing red eyes, long thin arms, and wrinkled fingers. It hides silently and waits for an opportunity to trouble humans.

The Baubas is particularly dangerous at night. It harasses sleeping people, pulls their hair, and is sometimes said to sit upon their chests and suffocate them. Its touch brings terror, and few who encounter it ever clearly see its full form.

For children, the Baubas serves much the same role as the bogeyman in English-speaking traditions. Threats such as “Behave, or the Baubas will come and get you” were commonly used to frighten unruly youngsters into obedience.

Thus, the Baubas remains one of Lithuania’s most feared household spirits—a shadowy being with red eyes and grasping fingers that waits in the darkness for the careless and the disobedient.

Karakondzhul

by

Tradition / Region: Serbian, Macedonian, Bulgarian, Turkish, Albania, Kosovo
Alternative names: Karakondzhal, Karakoncolos
Category: Demon

The Myth

The Karakondzhul is a terrifying winter demon from Balkan and Anatolian folklore that appears during the darkest and coldest days of midwinter. These creatures emerge during the dangerous period between Christmas and Epiphany, especially during severe frosts and the “unbaptized days” of winter when the boundary between the human world and the spirit world was believed to weaken.

The demons rise from rivers, caves, frozen lakes, abandoned places, and other unclean locations after midnight. They wander through villages, fields, and riverbanks until the first rooster crows at dawn. During these nights people avoided traveling alone because the Karakondzhuls were believed to attack travelers, leap onto their backs, and force them to run wildly through the darkness until exhaustion or death.

In Serbian tradition, Karakondzhuls were associated with the spirits of children conceived or dead during the impure winter period. They were believed to especially target women and children, scratching faces, drinking blood, and devouring victims.

The appearance of the Karakondzhul changes constantly. Folklore describes them as shaggy black or red humanoids with horns and tails, naked thorn-covered creatures, horse-bodied beings with human heads and wings, monstrous little people that lure victims onto dangerous ice, or animals such as dogs, sheep, and calves. Some traditions considered them werewolf-like beings capable of changing shape freely.

In Turkish and Anatolian folklore, the related Karakoncolos appears as a small black hairy creature roughly the size of a monkey, child, or cat. It roams winter roads at night questioning travelers with strange riddles such as “Where are you from?” and “Where are you going?” The answer had to include the word kara, meaning “black.” If the traveler failed, the creature attacked them using a massive comb.

People believed iron, fire, bread, salt, ashes from the Christmas badnjak fire, and sharp metal objects could repel the demon. In some regions combs were hidden during winter so the Karakoncolos could not use them as weapons.

The Karakondzhul was feared not simply as a monster, but as a spirit of the dangerous winter season itself — a creature of darkness, frost, wilderness, and the chaotic nights when the world temporarily fell outside divine protection.

Vodeni Demoni

by

Tradition / Region: Serbian Mythology
Alternative names: Vodeni Čovek, Vodenjak, Water Demons
Category: Demon, River Dweller

The Myth

In Serbian folk belief, water was not viewed as an ordinary natural element but as a living supernatural force inhabited by spirits and demons. Rivers, springs, lakes, mills, and deep waters were believed to possess consciousness, magical power, and dangerous invisible inhabitants known as vodeni demoni — water demons.

People spoke to water as if it were alive, greeting it respectfully and asking it for healing and protection. Certain waters were believed to cure illness, restore youth, grant fertility, or protect against evil spirits. Other waters, however, were feared as haunted places inhabited by deadly supernatural beings that dragged humans beneath the surface.

According to folklore, many rivers demanded sacrifices and regularly claimed human lives through drowning. Some rivers became infamous for frequent deaths and were believed to hunger for victims. Water demons especially haunted deep rivers, whirlpools, mills, bridges, springs, and isolated crossings.

One of the most feared beings was the Vodeni Čovek — the Water Man — a spirit appearing in human form. He lured travelers crossing rivers or walking near dangerous waters, pulling them beneath the surface and drowning them. In Kosovo and other regions, adults frightened misbehaving children with warnings that the “Water Man” would carry them away.

Watermills were considered especially dangerous places because demons, vampires, and devils gathered there during the night. Serbian folklore claimed that every mill housed evil spirits, and many legends described vampires attacking travelers or millers inside lonely mills beside rivers. The famous vampire Sava Savanović was said to haunt a watermill where he murdered those who entered after dark.

Flowing water itself possessed magical properties. “Living water” was pure running water flowing naturally through springs and rivers, while stagnant “dead water” was considered spiritually dangerous. Some waters were believed to become wine for a moment at midnight before Epiphany, while miraculous springs hidden in caves or mountains supposedly healed blindness, deafness, infertility, and disease.

Many rituals involving water were performed for protection against demons. Before thunderstorms, containers of water were covered so devils fleeing lightning could not hide inside them. People avoided drinking from rivers or springs at night for fear of swallowing evil spirits together with the water.

Water was also deeply connected to death and the afterlife. It was believed the souls of the dead suffered terrible thirst in the next world, so water was placed near corpses, poured onto graves, or carried in funeral rituals for the deceased. After someone died, water inside the house was often thrown away because people believed the soul of the dead had entered it.

Certain magical waters possessed special powers. “Untouched water” collected before sunrise retained supernatural strength and was used in rituals, healing, childbirth, and sacred bread-making. “Water of forgetting” supposedly caused those who drank it to forget their families, homeland, and even their faith.

Demons were believed to hide within polluted or spiritually corrupted waters. Rivers before St. George’s Day were feared because devils supposedly dwelled in them during that time. Some springs were avoided because fairies, witches, or dark spirits bathed there and contaminated the water with supernatural power.

Despite their danger, water spirits were not always purely evil. Some waters were guarded by benevolent supernatural beings who protected communities, healed the sick, and brought fertility, rain, and prosperity. Serbian folklore therefore treated water as both sacred and terrifying — a living gateway between the human world and the invisible realm of spirits and demons.

Ocheretyanyk

by

Tradition / Region: Ukrainian Mythology
Also Known As: Reed Devil, Spirit of the Reeds
Category: Demon, Swamp Dweller

The Myth

The Ocheretyanyk is a mysterious spirit from Slavic folklore associated with reeds, marshes, and wetlands. Its name comes from the Ukrainian word ocheret, meaning “reed,” and the creature was believed to dwell deep within thick reed beds near rivers and swamps.

Very little is known about the Ocheretyanyk compared to other Slavic spirits. Folklore usually describes it as a devil-like being tied to a specific place rather than a wandering demon. It was feared as a strange supernatural presence capable of terrifying travelers who passed too close to the reeds at night.

One surviving legend tells of a man riding near a marsh who encountered a strange white ram with claws, screaming unnaturally beside the reeds. Believing it to be an ordinary animal, the man lifted it onto his cart. Immediately the horses became unable to move under its weight. When he tried to throw the creature off, it would not leave the cart no matter how hard he struggled.

Only when the roosters crowed at dawn did the creature finally leap away on its own. Laughing mockingly, it disappeared back into the reeds.

Stories about the Ocheretyanyk often resemble broader Slavic tales about supernatural fear spirits—unknown beings that appear suddenly in strange forms such as animals, objects, or distorted humans in order to frighten people wandering near dangerous places at night.

Palm Tree King

by

Tradition / Region: Iraqi Mythology, Mesopotamian Mythology, Sumerian Mythology
Alternative Name: –
Category: Demon

The Myth

The Palm Tree King was one of the strange and monstrous beings known as the Slain Heroes in ancient Sumerian mythology. These creatures appear in the epic Lugale, which tells the story of the warrior god Ninurta battling monstrous enemies to recover the stolen Tablets of Destiny.

The Slain Heroes served the monstrous being Imdugud, also known later as Anzu, who had stolen the divine Tablets of Destiny from the god Enlil, ruler of wind, storms, and the heavens. Ninurta set out to defeat these creatures and reclaim the tablets.

Very little survives about the Palm Tree King compared to the other monsters in the epic. Ancient texts mention him among the creatures allied with Imdugud, but few details describe his appearance or powers. His unusual name suggests a connection to sacred trees, fertility, or the wilderness of southern Mesopotamia.

Unlike many of the other Slain Heroes defeated by Ninurta during his campaign, the Palm Tree King may have escaped destruction. Some interpretations of the surviving myths describe him as the only monstrous servant of Imdugud not clearly slain in battle.

Reamso

Category: Demon

The Myth

Reamso is a powerful storm demon in Cambodian mythology associated with thunder, storms, and violent weather. He is most famous for his eternal battle against the sea goddess Moni Mekhala, a conflict believed to create thunder, lightning, and rain across the sky.

According to the legend, Reamso studied alongside the sea goddess Moni Mekhala and a princely figure named Vorachhun under the wise hermit Lok Ta Moni Eisei. One day, the hermit announced that he would reward the most clever student with a magical crystal ball of great power. To decide the winner, he challenged his students to collect a glass of morning dew.

Moni Mekhala used her intelligence to win the contest. She spread a cloth across the grass overnight and squeezed the collected dew into a glass the next morning. Impressed by her ingenuity, the hermit rewarded her with the magical crystal ball. Reamso received a magical diamond axe, while Vorachhun received a magical dagger.

Reamso became jealous of Moni Mekhala and desired the crystal ball for himself. Determined to seize it, he set out to hunt her down. During his pursuit, he encountered Vorachhun and killed him before continuing after the goddess.

When Reamso finally confronted Moni Mekhala, she attempted to evade him rather than fight. Furious, the storm demon hurled his diamond axe at her through the sky. Each throw of the axe created the sound of thunder. To defend herself, Moni Mekhala raised her crystal ball into the heavens, producing brilliant flashes of lightning that blinded Reamso and allowed her to escape.

As the battle continued across the sky, the clash between thunder and lightning created rain that fell upon the earth. Some of the rain touched the body of Vorachhun, reviving him, and he then rose into the heavens to continue searching for Moni Mekhala and Reamso.

In Cambodian tradition, storms, thunder, lightning, and rain are believed to be the result of the endless chase and battle between Reamso and Moni Mekhala in the sky.

The Myth

Mystan Kempir is a demonic old woman from Central Asian folklore. She is feared as a witch who steals and replaces children, poisons food, and places curses upon people. Some legends also describe her keeping captives in the underworld, where she devours them alive.

Although she appears as an elderly woman, Mystan Kempir is said to possess unnatural speed and strength, capable of outrunning or even catching a galloping horse. She is known more for deception than direct violence, often defeating people through tricks, manipulation, and cunning rather than force.

Stories describe Mystan Kempir disguising herself as an ordinary old woman in order to enter homes unnoticed. Once welcomed inside, she brings misfortune, danger, or death. In heroic tales, even powerful batyrs can struggle against her schemes and magical tricks.
