Adze

An ordinary firefly flies in through a house window at night, with no one suspecting a thing. But if captured, this small insect instantly transforms into a monstrous humanoid creature, far more dangerous than it seemed. Before capture, it drains the blood of sleeping children, spreading disease with no one realizing where the real evil was coming from.

A being that flies as a firefly and so enters homes to suck the blood of sleepers, especially children, spreading disease. If caught, it takes a monstrous human form and becomes far more dangerous.

Within the folk and mythological corpus compiled by the Codex Monstrorum, the creature Adze 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.

It is bound to the Ewe conception of witchcraft (adze) as a force that possesses people: the witch harbors an adze that drives it to attack kin. It explains child deaths and epidemics, linking the night insect to disease transmission.

Defenses: killing the suspect firefly, divination to identify the adze's host, purification rites. Adze accusations fell on marginal persons; confessing or being 'cured' of the adze was part of the social process.

First appearance and primary records: A vampiric spirit of the Ewe people of Ghana, Togo, and Benin; documented in West African ethnography and studies of Ewe witchcraft (adze/aze).

Oral transmissions and preserved manuscripts indicate that legends surrounding Adze 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.

In free form, a firefly slipping through any gap; if caught, it becomes a dark-skinned humanoid with a large head, claws, and glowing eyes, with an insatiable hunger for blood and palm oil.

It rationalizes disease and child mortality and structures the Ewe witchcraft-accusation system. It binds the night insect, possession, and social tension around misfortune and envy.

An insect-vampire that anticipates the idea of a disease vector; it differs from the Slavic undead by being a possession-spirit, and from the asanbosam by attacking inside the home rather than in the forest — drawing near the Akan obayifo.

Present in Ewe oral literature and in anthropological studies of African witchcraft; it spread in world-vampire compilations as the 'firefly vampire', a striking case of a mythologized disease vector.
