A kolodechnik is a type of brownie spirit in Russian folklore and is regarded as the master and guardian of a well. Each kolodechnik is bound to a specific well, which it protects as its own domain.
The spirit is believed to dwell within the depths of the well, watching over the water and ensuring its proper use. Every well has its own kolodechnik, and the spirit does not stray from the place it guards.

Deep in the mountainous forests of Japan, ancient trees are believed to be inhabited by spirits known as Kodama. These spirits dwell within very old trees, and their lives are inseparably bound to their host. If the tree dies, the kodama perishes with it; if the kodama is destroyed, the tree cannot survive.
Kodama are rarely seen, but their presence is often heard. In forests and mountain valleys, sounds sometimes echo longer than they should, returning with an unnatural delay. This phenomenon, known as yamabiko, is traditionally attributed to kodama responding to human voices. When they do appear visually, kodama may manifest as faint, distant orbs of light, or as small, oddly shaped, vaguely humanoid figures moving through the forest.
Although their bodies may leave the tree temporarily, kodama remain guardians of their groves, tending to the balance of nature. Trees inhabited by kodama are considered sacred. Villagers traditionally mark such trees with shimenawa, sacred ropes, to signal their divine status and warn against harm. Cutting down a tree that houses a kodama is believed to bring a powerful curse, capable of plunging an entire community into ruin. In some traditions, when an ancient tree is cut and blood appears to flow from the wood, it is taken as proof that a kodama lived within it.
The belief in tree spirits is ancient. In early Japanese texts, kodama are closely associated with gods and yōkai alike. The tree deity Kukunochi no Kami, recorded in the Kojiki (712 CE), is sometimes interpreted as a kodama. In the Heian-period dictionary Wamyō Ruijushō, tree gods are listed under the name “kodama.” Classical literature such as The Tale of Genji refers to kodama alongside oni, fox spirits, and gods, indicating their liminal nature between kami and yōkai.
Kodama are said to take many forms. Some appear as ghostly lights, others as animals or humans. One story tells of a kodama that fell in love with a human and left its tree, assuming human form in order to meet them. According to medieval Shinto texts such as the Reikiki, kodama may dwell in groups deep within the mountains and are sometimes heard speaking, particularly at moments of death.
Regional traditions preserve related beliefs. On Aogashima and Hachijō-jima in the Izu Islands, shrines are built at the base of great cryptomeria trees and worshipped under the names kidama-sama or kodama-sama, and festivals are held whenever such trees are cut. On Okinawa, tree spirits are called kiinushii, and prayers are made before felling any tree. Nighttime sounds resembling falling trees are believed to be the cries of kiinushii, followed by the tree withering days later. The Okinawan yōkai kijimuna is sometimes said to be a manifestation of these spirits.
In the Gazu Hyakki Yagyō by Toriyama Sekien, kodama are depicted as elderly men and women standing among trees, with the explanation that when a tree reaches a hundred years of age, a divine spirit comes to dwell within it. Through these traditions, kodama remain enduring symbols of the living soul of the forest and the sacred bond between trees and spirit.

Category: Spirit masters / animistic spirits
In traditional Yakut belief, ichchi are spirit masters that inhabit objects, places, and natural phenomena. According to this worldview, nature is alive in all its parts, and every thing—large or small—possesses its own indwelling spirit. Mountains, trees, rivers, lakes, fire, tools, dwellings, and even the most ordinary household objects were believed to have an ichchi.
Ichchi could dwell in prominent features of the landscape, such as forests or bodies of water, acting as guardians or owners of those places. At the same time, they could also inhabit humble or easily overlooked things, such as the firebox used in the hearth or tools used in daily work. Because of this, people were expected to treat both nature and objects with care and respect.
When approached properly, an ichchi could become a patron spirit to a person or household, offering protection, good fortune, and harmony. Disrespect, neglect, or improper behavior toward the object or place inhabited by an ichchi could provoke misfortune, illness, or bad luck.
Communication with ichchi took the form of prayers called algys, which were spoken to honor or appease the spirits. Offerings were an essential part of this relationship. These could include horsehair ornaments, scraps of cloth known as salama, non-animal foods, kumiss (fermented mare’s milk), or money. The offerings acknowledged the spirit’s presence and authority.
Ichchi are distinct from other spiritual beings in Yakut cosmology. They are not the high benevolent deities known as Aiyy, nor are they the malevolent spirits such as Abaahy or Uor. Instead, ichchi occupy a middle position as ever-present spirit owners of the world itself.
Similar beliefs in spirit masters exist among neighboring peoples. Other Turkic-speaking groups refer to such spirits as eye or ezi, the Buryats call them ezhins, and the Mongols know them as edzens, reflecting a shared animistic understanding across Inner Asia.

Igrets is a figure from Russian folk belief understood as a malicious type of domovoi, the household spirit. Unlike the more ambivalent or protective domovoi, the igrets is known specifically for cruel and troublesome behavior. It hides objects, causes disorder in the house, torments livestock, and interferes with daily life through spiteful tricks rather than playful mischief.
In popular belief, the igrets is sometimes identified directly with the house spirit itself, and in other cases confused with the devil or a demonic presence dwelling within the household. Its actions are described as aggressive and harmful: breaking things, frightening people, and provoking physical or emotional distress. Because of this, its “jokes” were considered dangerous rather than humorous.
Belief in the igrets was widespread in central and southern regions of Russia, including the Ryazan, Tambov, Kursk, Tula, Voronezh, Penza, and Oryol provinces, as well as the Don region. From at least the 19th century, everyday speech in these areas included expressions such as “Igrets take you,” “Igrets knows him,” or “Igrets is with you,” used to explain misfortune, sudden anger, or destructive behavior.
In some regions, the word igrets was also used to describe physical or psychological disturbances. In Kursk province, it could refer to a violent fit or hysterical episode accompanied by screaming. In Tambov and the Don region, it could mean paralysis or sudden loss of control over one’s limbs. These meanings suggest that the igrets was associated not only with household disorder, but also with unexplained illness or loss of bodily control.
Overall, the igrets represents the darker side of domestic spirits in Russian folklore: a presence within the home that causes chaos, suffering, and fear, and serves as an explanation for sudden misfortune, destructive impulses, or frightening physical episodes.

Category: Spirit
Angako-di-Ngato are spirits feared in the folklore of the Kalinga people of northern Luzon. They are believed to be the cause of illness, afflicting humans with sickness when they draw near or are offended.
When disease strikes without an obvious cause, it is said that Angako-di-Ngato are responsible. These spirits act invisibly, entering the human body or lingering around people, weakening them and bringing suffering.
In Kalinga belief, illness is not merely physical but the result of contact with these malevolent spirits, whose presence disrupts the balance between humans and the unseen world.

Alvina is a spirit of the air, known to wander endlessly through the sky. When the wind howls and roars, people say, “Listen! Alvina is crying.” Her presence is heard rather than seen, carried on storms and restless gusts that sweep across the land.
According to the legend, Alvina was once a king’s daughter. Against her parents’ wishes, she married the wrong man. For this act, her parents cursed her to wander forever, stripped of rest or peace. From that moment on, she was bound to the winds, condemned to eternal roaming.
Her name has led some to believe that she was the daughter of an elven king, linking her to an otherworldly royal lineage rather than a purely human one. Whether princess or elf-child, Alvina’s fate remained the same: to drift endlessly through the air, her sorrow echoing whenever the wind rises.
Thus, Alvina is remembered as a mournful air spirit, her lament still heard whenever the wind cries across West Flanders.

Category: Water spirit
In Swedish folklore, Näcken dwelled in lakes, rivers, streams, and mill waters, haunting places where the current moved quietly or gathered strength beneath the surface. He was not a single spirit but a powerful water-being known by many names, feared and respected wherever people lived close to water.
Näcken most often appeared as a naked man, sometimes young and slender, sometimes old and bearded, seated upon a rock or at the water’s edge. His hair was said to be green or woven with foliage, as if grown from the river itself. In his hands he held an instrument, most often a violin, though he was also known to play horns, flutes, or other melodies. His music was said to be irresistibly beautiful. Those who heard it felt drawn toward the sound, their feet carrying them closer to the water without their will.
Näcken was a master of deception. Though water might seem shallow and harmless, he could seize a person’s footing, locking their legs in place and pulling them beneath the surface. Many drownings were blamed on him, and children were warned never to trust the calm of a stream or the beauty of music drifting across the water at dusk.
At times, Näcken took other forms. He could appear as animals — a black or white horse, a bull, a dog, or a cat — and these shapes often bore a subtle wrongness, such as having three legs instead of four. He could also disguise himself as floating objects or tempting treasures, lying in wait for the unwary.
Näcken was not merely a minor spirit, but a powerful force of the natural world, sometimes spoken of as nearly divine. He embodied the danger of water itself: beautiful, life-giving, and deadly. To encounter him was to be reminded that rivers and lakes were alive, watching, and never fully under human control.

Alternate Names: Raroh, Raróg
Category: Bird, Spirit
The Raróg is a being of fire, most often seen as a flaming falcon or hawk streaking across the sky. It is not a creature of nests or forests, but one bound to heat, flame, and the upper reaches of the world. When it moves, it may blaze like a living ember, spiral through the air like a whirlwind, or descend suddenly in a flash of fire.
Some traditions tell that the Raróg may be born in an unusual way. An egg kept warm upon a household stove for nine days and nights can hatch into the spirit. Once it comes into being, it does not remain fixed in shape. At times it appears as a fiery bird, at others as a dragon-like form, a small humanoid spirit, or a spinning column of flame. Like fire itself, its nature is unstable and ever-changing.
The Raróg is said to dwell at the crown of the Slavic world tree, where it guards the entrance to Vyraj, a warm and radiant realm associated with life, renewal, and the seasonal flight of birds away from winter. From this height, it watches the boundary between the human world and a distant paradise beyond decay and cold.
In some regions, particularly in Polish folklore, the Raróg appears in a smaller and gentler form. It is described as a tiny fire-bird that can be carried in a pocket and brings good fortune to the one who possesses it. Even in this form, it remains a creature of flame, closely tied to later legends of the Firebird, whose feathers continue to glow long after being plucked.
Across all its tellings, the Raróg endures as a living embodiment of fire itself — swift, radiant, and dangerous, forever moving between worlds in flickers of flame.
