Sources do not record a single, unified origin narrative. Within the Celtic folkloric frame the cat sìth is presented primarily as a fairy creature of the otherworld, particularly in Scottish accounts. An alternative strand recorded in folklore frames some cat-sìth tales as referring not to a non-human fairy but to a human practitioner of magic (a witch) who could transform into a cat up to nine times. The material supplied emphasizes this duality—otherworldly fairy being versus shapeshifting witch—without providing a systematic cosmology or a definitive origin account.
Attested descriptions in the supplied sources describe the cat sìth as resembling a large black cat with a white spot on its chest. Some legends characterize it as a spectral cat that haunts the Scottish Highlands. One source reports that in some tellings it walks on its hind legs; this trait is noted as reported in those accounts rather than as universally consistent across all traditions. Beyond these features the provided material supplies no consistent additional physical details.
The excerpts attribute a haunting or persistent presence in Highland landscapes and, in some folkloric variants, the capacity for transformation: certain traditions state the cat-sìth was a witch who could transform into a cat nine times. Walking on hind legs is recorded in some accounts as an unusual behavior signaling otherworldliness. The supplied sources do not enumerate further powers (such as speech, soul-stealing, or luck-bringing) or detailed supernatural capabilities.
Alp-luachra
Alp-luachra is an Irish folkloric fairy described as an invisible being that consumes half of a person's nourishment by taking the unseen 'pith' or 'quintessence' of food; accounts say it appears in the form of a newt and crawls down a sleeping person's mouth at water margins.
Aos Sí
Aos Sí are a broad class of supernatural beings in Gaelic (Irish and Scottish) folklore associated with the mounds and liminal places of the landscape. They are variously described as descendants or later forms of the Tuatha Dé Danann, ancestral or nature spirits, or otherworldly folk who coexist with humans and can be helpful or dangerous when offended.
Bauchan
A household-associated hobgoblin from Scottish Highland folklore, the bauchan is portrayed as ambivalently belligerent and helpful; in at least one recorded tale it accompanies a human household across the Atlantic and can shapeshift into a goat.
Beithir
In Scottish Gaelic tradition the beithir is a very large snakelike creature—often called a serpent or dragon—associated with mountains, corries and bodies of water. It is portrayed as venomous and deadly in local tales, linked in etymology and interpretation to lightning/thunderbolt imagery, and classed among water-associated monsters (fuath).
Biasd Bheulach
A named monster or spirit reported in Scottish folklore as haunting the Odal (Odal) Pass on the Isle of Skye. Attested primarily as a place‑bound uncanny being in modern summaries and lists of Scottish folk creatures, the entity is recorded with very limited detail in the cited sources.
Biróg
Biróg (also Biroge, Birog of the Mountain) is a female supernatural helper in Irish narrative tradition who aids Mac Cinnfhaelaidh/Cian in gaining access to the imprisoned Ethniu and rescues the surviving infant of that union; later retellings variably portray her as a leanan sídhe (female familiar spirit), a filidh (poet/seer), or a druidess.
Bodach
A Gaelic folkloric personage literally meaning "old man" (Old Irish botach) who functions variously as a trickster, bogeyman, household figure and — in some accounts — an omen of death (Bodach Glas). The term also carries historical social meanings (tenant/peasant) and is sometimes identified with higher mythic figures (e.g., Manannán mac Lir) in specific tales.
Brownie
A household spirit from Scottish and related British traditions that performs nocturnal domestic labour in return for small offerings left by the hearth. Brownies are protective, place-tied domestic beings who work while humans sleep and will depart or become mischievous if offended.
Ceasg
A Scottish Gaelic mermaid-like being described as a woman with the upper body of a human and the tail of a grilse (young salmon). In tradition she can form marriages with humans, grant boons to those who capture her, and in some tales appears large and dangerous, able to swallow people whose rescue requires finding and destroying a special life-egg.
Church Grim
A site-bound guardian spirit in English, Scottish and Nordic/Scandinavian folklore that watches over an individual Christian church and its churchyard, defending the consecrated ground from profanation and hostile spirits. Forms and origin accounts vary by region, including a large black dog in English tradition, the bound spirit of an animal (often a lamb) in Scandinavian accounts, and in some Scottish strands the spirit of the most recently buried person acting as a temporary watcher.
Clurichaun
A solitary Irish fairy-like household and cellar spirit associated with drinking places (breweries, pubs, wine cellars). He is a heavy drinker and smoker, a mischievous trickster who can also act as a protective domestic spirit for a household that tolerates him; accounts are primarily from 19th-century collectors and later summaries.
Crom Dubh
Crom Dubh is a fluid mythological and folkloric figure from Irish tradition, variously represented as a remnant cultic god, a pagan chieftain or robber, a servant-figure, and the focal figure of seasonal first-fruits rites (Crom Dubh Sunday). In later narratives he is frequently framed as an antagonist subdued or reinterpreted by St. Patrick.
