Leyak

By day, she's just another ordinary person in the Balinese village, no one would suspect a thing. At night, her head completely detaches from her body, carrying the heart, lungs, and liver dangling beneath it, and flies in search of blood, especially from newborns. She serves directly under the witch queen, and her secret training culminates, according to legend, in power over life and death itself.

A practitioner of black magic who at night transforms into a floating head with dangling viscera — heart, lungs, and liver trailing beneath the severed head. It flies in search of blood, especially of newborns and women in childbirth.

Within the folk and mythological corpus compiled by the Codex Monstrorum, the creature Leyak occupies a distinctive role in the symbolic imagination of its culture of origin. Its mythos articulates primal human anxieties, the mystery of untamed wilderness, and social norms preserved through the lens of bestiary literature.

The leyak articulates the dark face of Balinese Hinduism. Codex distinguishes the dual nature — by day, the leyak is an ordinary person (often a woman) who secretly practices left-hand magic; by night, it detaches its head and organs to hunt; the link to Rangda — the leyaks are the servants of the witch-queen, and their training culminates, according to legend, in mastery over life and death; and the function in the dual balance (rwa bhineda) — like the disease and sorcery the Balinese fight with offerings, exorcisms (balian), and the protection of the Barong, the leyak embodies the malign pole necessary to the island's cosmic tension.

In tradition the leyak embodies the terror of witchcraft hidden among neighbors: the evil that hides beneath an ordinary face and attacks nascent life. The Balinese protect themselves with offerings, amulets, and rites; the fear of the leyak organizes nocturnal conduct and the watch over pregnant women and infants.

First appearance and primary records: A flying witch of Balinese mythology (Indonesia), a central figure of the island's black magic (pengiwa); subject of the demon queen Rangda and attested in the oral and ritual tradition of Bali.

Oral transmissions and preserved manuscripts indicate that legends surrounding Leyak underwent substantive evolution over successive centuries. From archaic oral traditions to classical and medieval written records, each period reframed the creature according to its own ethical and cosmological paradigms.

The nocturnal morphology is that of a detached head with a long tongue and fangs, trailing the heart and viscera like a luminous wake. By day, indistinguishable from any person — it is precisely this dual form that makes it an invisible threat within the community.

The leyak organizes the fear of hidden witchcraft and the pole of evil in the dual cosmology of Bali: it gives form to the sorcery that disguises itself as ordinary people. It embodies disease and the threat to nascent life, justifying the protective rites and watchfulness that structure Balinese night life.

Beside the Malay penanggalan, the Thai krasue, and the Filipino manananggal (all flying viscera-suckers), the leyak belongs to the remarkable Southeast Asian family of the head-witch with entrails; it is distinguished by its insertion in the Balinese dual cosmology and by its link to Rangda and the Barong.

From Balinese oral and ritual tradition to sculptures, masks, and dance (the leyaks accompany Rangda in the Barong drama) and to Indonesian horror cinema, the leyak is fixed as the flying witch par excellence of Bali, kin to the viscera-suckers across Southeast Asia.
