Sacháyoj

by

Tradition: Argentine Mythology
Alternative Names: Lord of the Forest
Category: Forest dweller

The Myth

Sacháyoj is an ancient supernatural being who protects the forests of northwestern Argentina. He appears as an aged figure covered from head to toe in extremely long, white hair, giving him a wild and otherworldly appearance. In some depictions, he carries a long cane in one hand as he wanders through the woodland. His strange appearance sets him apart from ordinary humans, marking him as a powerful guardian of the natural world.

As Lord of the Forest, Sacháyoj watches over the trees and protects the woodland from unnecessary destruction. Those who cut down trees without good reason risk provoking his supernatural punishment. When someone fells a tree needlessly, Sacháyoj can make the tree disappear forever, ensuring that it can never be recovered. Through this power, he warns people against wasteful destruction and defends the forest against those who fail to respect its natural riches.

Cherruve

by

Tradition: Mapuche Mythology, Argentine Mythology, Chilean Mythology
Alternative Names: Cherruve, Cherufe
Category: Flame

The Myth

The Cherruve is a fearsome supernatural being associated with comets, meteors, volcanoes, and destructive fire. It is often described as a blazing comet streaking across the night sky, but it can also appear as a gigantic serpent with a human head and molten lava dripping from its mouth. In some regions, it takes the form of a seven-headed dragon, a fiery-eyed giant, or even a two-legged goat with burning eyes. Cherruves dwell underground and within volcanoes, emerging into the sky like flaming celestial bodies.

The appearance of a Cherruve is considered an omen of disaster, foretelling epidemics, the death of great leaders, and other misfortunes. Their movements beneath the earth cause earthquakes, while their fiery vomit becomes lava flowing down volcanic slopes. They are said to create thunder by tossing human heads through the air. Some particularly monstrous Cherruves demand the sacrifice of Mapuche maidens and threaten to withhold the flow of rivers when their demands are refused. Their forms can also include meteorites and strangely shaped volcanic rocks, which sorcerers collect and use as supernatural weapons against their enemies. These enchanted stones can be commanded to spread disease, drain blood, and bring death before returning to their masters.

Despite their destructive nature, Cherruves are also capable of love, jealousy, and grief. One Cherruve married a Cloud, and together they had a beautiful daughter named Snow, whose body was pale and delicate. The Cherruve jealously guarded his wife, but his enemy Wind abducted her, and whenever Wind carried Cloud over the volcano, her tears fell as rain while the Cherruve’s despair erupted in devastating volcanic outbursts. He became equally protective of Snow, forbidding her from leaving the mountain during daylight. Yet Snow longed to see the world beyond her home. One day, she escaped and marvelled at the sunlight, birdsong, and the colours of the world, growing happier even as her strength faded. When Wind carried her mother away once more, Snow collapsed from exhaustion. The Sun, moved by love for the beautiful girl, descended to kiss her. When her father finally found her, Snow had vanished, leaving behind only a puddle of crystalline water.

Luz Mala

by

Tradition: Argentine Mythology, Uruguayan Mythology
Alternative Names: Evil Light, Luz Mala
Category: Flame

The Myth

The Luz Mala, meaning “Evil Light,” is one of the best-known supernatural phenomena in the folklore of Argentina and Uruguay. It is especially feared in rural areas, where mysterious lights are said to appear far from towns and settlements. The phenomenon takes the form of an intensely bright ball of light that floats just a few inches above the ground, illuminating the surrounding darkness with an eerie glow.

The appearance of the Luz Mala is traditionally regarded with fear and suspicion. Its strange, low-floating light is associated with the mysterious and potentially dangerous forces believed to inhabit the countryside. For generations, stories of these glowing spheres have contributed to the legend of the Evil Light, making it an important part of the rural folklore of both Argentina and Uruguay.

Guallipén

by

Tradition / Region: Argentine Mythology, Chilean Mythology
Alternative names: Waillepeñ, Huallepén, Huallepenyú, Huaillepenyí, Wayfü
Category: Cow

The Myth

The Guallipén is a strange animal with the body of a sheep and the head of a calf. It has four crooked legs, poor-looking wool, and makes a bleating sound like a sheep.

The Guallipén lives in low, humid places near bodies of water, especially swamps known in Mapuche tradition as münoko. It moves by pushing itself forward with its front legs while dragging its hind legs behind it.

On land, the Guallipén is said to be harmless, but in the water it becomes dangerous and attacks fiercely. When it encounters livestock, it can mate with them and cause their offspring to be born with deformities.

A pregnant woman who sees a Guallipén in a perimontu, a supernatural vision, receives a terrible omen concerning her unborn child. Depending on the tradition, the child may be born with deformed or atrophied limbs, rickets, an intellectual disability, or without bones.

Because of this danger, sexual relations near wetlands were traditionally regarded as taboo. A child believed to have been conceived after such an encounter could be described as a wallipeñ kulliñ, an incarnation of the Guallipén.

Ucumar

by

Tradition / Region: Bolivian Mythology, Argentine Mythology
Alternative names: Ucumarí, Jucumari, Ucumare
Category: Bear

The Myth

The Ucumar is a fearsome creature of Argentine and Andean folklore, particularly associated with northwestern Argentina and neighboring Bolivia. Its name means “bear” in Aymara, and it is commonly described as a bear-man whose appearance varies from a squat, shaggy bear with human features to a wild, hairy man with a long beard and a narrow forehead.

The creature is said to dwell in caves deep within ravines, although it frequently wanders along rivers and springs, where it bathes. Its large footprints, resembling those of a bear, are often said to reveal its presence. Traditions also describe it as immensely strong and agile enough to climb the tallest trees.

The Ucumar is most feared for kidnapping people. According to many legends, the male abducts women and fathers children with them, while other traditions tell of a female Ucumar that captures young men. It is also said to steal children, making it a common figure used to frighten youngsters into obedience.

Those who encounter the Ucumar describe it as appearing suddenly and inspiring overwhelming terror. If someone shouts at the creature, it is said to answer from a distance with voices that sound eerily human. When attacked by dogs, it defends itself by striking them with a heavy club.

Among the Colla people, the Ucumar is instead portrayed as a gigantic ape-like being that walks upright through the forests. In this tradition, the male pursues women while the female hunts men, carrying their victims into remote wilderness where they are beaten to death. Some later writers have suggested that stories of the Ucumar may have been inspired by encounters with the spectacled bear of the Andean forests, though the legendary creature itself is regarded as a supernatural being rather than an ordinary animal.

Mayup Mamman

by

Tradition / Region: Argentine Mythology
Alternative names: Mother of the River
Category: Nymph

The Myth

Mayup Mamman, whose name means “Mother of the River,” is a benevolent yet powerful river spirit in Argentine Andean folklore. She is said to dwell within Mishky Mayu (“Sweet River”), where she serves as the guardian of its waters and all the fish that live within them.

She appears as a beautiful fair-haired woman who silently glides across the river in a canoe. Rather than harming people without reason, Mayup Mamman watches over the natural balance of the river, ensuring that its resources are not abused.

When fishermen take only what they need, she leaves them in peace. However, if they become greedy and overfish the river, she punishes them. She is said to curse those who exploit the river, causing their canoes to overturn and sink beneath the water as retribution for their disrespect toward nature.

Mayup Mamman represents the belief that rivers are living, sacred places protected by supernatural guardians who reward respect but punish greed, emphasizing humanity’s responsibility to preserve the natural world.

Pombero

by

Tradition / Region: Paraguay Mythology, Brazilian Mythology, Argentine Mythology
Alternative names: Pomberito, Karai Pyhare, Pyrague, Kuarahy Jára, Cho Pombé, Lord of the Night
Category: Goblin

The Myth

The Pombero is a mysterious nocturnal being that inhabits forests, abandoned houses, barns, and lonely rural places throughout the Guaraní-speaking world. Usually active after dark, he is known as the Lord of the Night and is one of the most feared and respected figures in Paraguayan folklore.

He is commonly described as a short, ugly humanoid with extremely short arms and hairy hands and feet. His feet allow him to move silently through the forest, while the touch of his hairy hands is said to send a cold shiver through those he touches. The Pombero possesses many supernatural abilities, including invisibility and the power to squeeze through impossibly narrow openings.

Before appearing, he often announces his presence with strange whistles and the songs of nocturnal birds, which he can imitate perfectly. Because of this, he is regarded as a protector of birds and is said to punish children who hunt them with slingshots.

Although generally considered a mischievous spirit rather than an outright monster, the Pombero delights in causing trouble. He steals eggs, honey, and chickens, scatters grain and food stores, releases livestock, and frightens horses so that riders are thrown to the ground.

He is also associated with mysterious pregnancies and is sometimes blamed for fathering children born unusually hairy or unattractive. In darker traditions, he is said to kidnap lonely or ungrateful young women, force his affection upon them, and violate them. Similar stories are also attributed to the Guaraní being Kurupi.

Because of his unpredictable nature, people seek to appease the Pombero with offerings. Cigars and rum are his favorite gifts, though honey is also considered acceptable. Families in rural Paraguay often leave these offerings outside at night to prevent his mischief.

Those who regularly honor him may gain his friendship. A satisfied Pombero is believed to protect homes, animals, and possessions, and sometimes rewards his benefactors with small gifts of his own.

Thus, the Pombero remains one of the most enduring figures of Guaraní folklore—a silent lord of the forests who walks unseen through the night, bringing either mischief or protection depending on how he is treated.

Luison

by

Tradition / Region: Paraguay Mythology, Argentine Mythology
Alternate Names: Luisõ, Luisón, Lobizón
Category: Dog

The Myth

Luison is one of the seven monstrous sons born to Tau, a spirit of evil, and Kerana, a mortal woman. Of their seven children, Luison is the seventh and most accursed. He is feared throughout Guaraní tradition and in parts of Paraguay, Argentina, and neighboring regions.

Luison appears as a hideous, giant dog-like creature, grotesque in form and repulsive to behold. He prowls at night, haunting graveyards and lonely places, feeding on carrion and the corruption of the dead.

According to the legend, the curse did not remain only with the original beast. It spread into the human world. Families believed that if a household had seven sons in succession, the youngest would be destined to become Luison. On his thirteenth birthday, the transformation would begin. The boy would change into a monstrous dog-creature and wander the night, driven by hunger and doom.

Because of this belief, traditions arose to prevent the curse. In some regions, the seventh son would be given special protection, baptized with powerful rituals, or even adopted by a godfather of high status so the curse could be broken.

Though feared as a devourer of the dead, Luison is also remembered as a tragic figure — a being born not by choice, but by fate, condemned to roam between the worlds of the living and the dead.
