The available sources do not supply a single canonical origin narrative for nü guǐ. In the comparative and encyclopedic accounts provided, such vengeful ghosts arise when a person suffers a cruel, unnatural, or unjust death or when funeral and burial/cremation ceremonies are omitted or improperly performed; the resulting unrest prevents the dead from attaining a settled post-mortem state and may produce a spirit that returns to seek redress or attention.
The provided sources do not give a consistent, documented physical description specific to nü guǐ. Encyclopedic discussions of 'vengeful ghosts' focus on motive and ritual status rather than standardized visual traits, so specific appearance details are not supported by the supplied material.
Sources characterize vengeful ghosts primarily by behavior: returning from the afterlife to seek revenge for cruel, unnatural, or unjust deaths and arising as 'unhappy' spirits when funerary rites are lacking. Comparative material on spirit possession notes that spirits in many traditions can interact with the living, including through possession, but the supplied texts do not document possession or other particular abilities as specific, universal traits of nü guǐ in Chinese sources.

Banshee
A female spirit of Irish and Scottish folklore whose wail heralds an impending death in a family of Gaelic descent. Not a cause of death — a witness to it.

La Llorona
The Weeping Woman of Mexican folklore — the ghost of a mother who drowned her children and now wanders rivers and lakes, weeping for them and taking other children she finds at night.

Rusalka
Water spirits in Slavic folklore — the spirits of young women who died by drowning or suicide, bound to rivers and lakes. Beautiful and dangerous, they can bewitch men to their deaths.

Strigoi
The vampire of Romanian folklore — either a living witch (strigoi viu) or an undead blood-drinker (strigoi mort). The source tradition from which the literary vampire emerged.

Ghoul
A ghoul is a demon-like or monstrous humanoid originating in pre-Islamic Arabian religion, traditionally associated with graveyards and the consumption of human flesh. The concept later entered broader folklore and has been widely reused and transformed in modern fiction and popular culture.
*Perkʷūnos
*Perkʷūnos is the reconstructed Proto-Indo-European thunder‑god hypothesized by comparative linguistics and mythology. Scholarly reconstructions portray him as a storm or thunder figure associated with fructifying rain and as the combatant who fights a multi‑headed water‑serpent to release life‑giving waters; no direct attestations from the Proto‑Indo‑European period survive and the figure is inferred from later Indo‑European traditions.
*Péh₂usōn (reconstructed)
Péh₂usōn is a hypothetical Proto‑Indo‑European pastoral guardian reconstructed by comparative scholars from parallels in Greek and Vedic traditions. Proposed as a Graeco‑Aryan ancestor‑figure, the reconstruction describes a protector of flocks, roads, and travellers rather than an attested historical cultic personality.
57 Mnemosyne
57 Mnemosyne is a large main-belt asteroid (S-type) discovered in 1859 and named after the Greek Titaness Mnemosyne. It is a non-sentient astronomical body studied for its orbital and rotational properties and has been used in dynamical measurements related to Jupiter.
Abaddon
In Hebrew scripture Abaddon is primarily a noun meaning 'destruction' or a section/condition of the underworld paired with Sheol; in the New Testament Book of Revelation Abaddon is personified as an angelic figure (Greek Apollyon) described as the king of an army of locusts released from the abyss during the apocalypse.
Aban Yasht
The Aban Yasht is a hymn from the Persian tradition that praises Anahita, a goddess associated with water, fertility, and wisdom. It consists of 132 stanzas and is part of the 21 Yashts collection. (Note: - Power tier should be "Primordial" or possibly "Cosmic", given that it's a hymn of great spiritual significance and associated with a goddess. - The article incorrectly states that Anahita is associa)
Abath
No corroborated folkloric entity named "Abath" is documented in the provided sources. The string appears in the supplied material only as a surname/personal name in Aruban/Dutch-Caribbean archival records and as an unrelated taxonomic or encyclopedic hit; no mythic attributes, origin stories, rituals, or apotropaic practices for an entity called Abath are present in the documents reviewed.
Abatur
Abatur is an uthra (celestial emanation) in Mandaeism described as the 'father of the Uthras' and called the Ancient (ʿattīqā). He resides on the boundary between the World of Light and lower regions, functions as a judge who weighs souls (Abatur Muzania), and supplies instructions and materials to the demiurgic uthra Ptahil in accounts from the Diwan (Scroll) of Abatur.
Abatwa (Twa / Batwa)
Abatwa (also recorded as Twa, Batwa, Mutwa; singular forms Barhwa or Murhwa in some transcriptions) are indigenous hunter‑gatherer peoples of the Great Lakes region of Central Africa, historically identified as some of the earliest inhabitants of the area. The available sources treat them as human ethnic groups whose livelihoods, lands, and populations have been severely affected by conservation policies and modern violence.
Abellio
Abellio is a theonym attested in Roman‑period inscriptions from the Comminges area of the Pyrenees and reported as worshipped in the Garonne Valley of ancient Gallia Aquitania. Surviving evidence is limited to a small number of inscriptions; scholars have variously hypothesized solar or arboreal associations and compared the name to forms of Apollo or to Celtic Belenus, but the deity's precise role in local cosmology remains uncertain.
Abraham
Abraham (originally Abram) is the foundational patriarchal ancestor in the Hebrew Bible whose life establishes a covenantal relationship between his family/people and God. He functions as an exemplar of faith, the progenitor of promised descendants, and a narrative anchor for claims of land, blessing, and communal identity in later religious traditions.
Abraun
Abraun is an attested name in German-language plant-legend scholarship (Der abraun, ein beitrag zur pflanzensagenkunde, 1916) and a short database entry (Wikidata) labels it as a spirit from German mythology. Surviving accessible documentation is extremely limited: the principal academic treatment is a 1916 contribution to pflanzensagenkunde (plant-saga studies), but the excerpts available here contain only bibliographic metadata and do not record tales, descriptions, or rituals.
Abtin
Abtin (Persian: آبتین), attested also as Athwya, is a mythic ancestral figure in Iranian tradition described in Avestan and later epic literature as one of a small set of formative human-like figures involved in preparing the corporeal world and as the father of the epic hero-king Fereydun in the Shahnama.
