A nocturnal spirit of Breton folklore (particularly Morbihan) whose name is glossed as 'Night Shepherd' or 'child of the night.' Accounts vary: some present the Bugul Noz as a small goblin-like nocturnal being that menaces shepherds and people who linger outdoors after dark; other informants describe a tall, foreboding twilight figure. It functions in local culture as a cautionary night-being that enforces avoidance of unsafe nighttime activity.
A natural feature in Celtic tradition, often imbued with spiritual significance. (Note: - Power tier should be Primordial=cosmic, given its association with natural features and spiritual significance. - Origin story missing entirely; add from source material (if available) or consult ex)
The supplied sources do not attest a supernatural entity named 'Buí'. The string appears in Irish place-name usage (notably in the toponym 'Bóthar Buí' cited on Wikipedia, referring to places such as Boherbue, County Cork; Draperstown, County Londonderry; and Enfield, County Meath). No folkloric descriptions, abilities, appearances, or rituals for a spirit called Buí are present in the provided material.

Bélchú is a human warrior-lord of Breifne in the Ulster Cycle of early Irish narrative tradition. In the preserved tale he shelters the wounded Ulster hero Conall Cernach, plots his murder, is himself killed when Conall turns the trickery back on him, and as a result becomes part of a revenge episode that exemplifies hospitality, honour, and martial reciprocity in the saga corpus.
Béḃinn (modern Béibhinn) is an early Irish personal name that also appears in medieval mythological material as a goddess-figure variously associated with childbirth and with the underworld; she is named as sister of the river-goddess Boann in some sources and is linked in others to the Irish Mag Mell or the Welsh Annwn.
Cadoc (Medieval Latin: Cadocus; Welsh: Cadog or Catwg) is represented in medieval Welsh sources as a late 5th–6th century Christian saint, monastic founder and teacher centered on Llancarfan. His Vita records portents at his birth, miraculous signs (a holy well, a vanishing boar) and numerous foundations and dedications across Wales, Cornwall, Brittany and Scotland; his life-functions in the sources are hagiographical: miracle-worker, educator and local patron invoked for cures in some Breton sites.
Cador (Latin Cadorius; early forms Cado, Cadwy) is a legendary aristocratic figure of the Arthurian and early British pseudo‑historical tradition, portrayed in medieval sources as a duke/earl/king and a military commander allied with King Arthur. His historicity is uncertain and debated by scholars; details derive from Geoffrey of Monmouth, later medieval poets (Layamon, Mannyng) and later genealogical interpretations.

In Ulster Cycle narratives he fights Conchobar and is slain by the hero Cúchulainn at the Battle of Rosnaree (Cath Ruis na Ríg); medieval compilations place him variably in different synchronistic chronologies.
Camulus (Gaulish Camulos) is a named divine figure of the Roman-period Celtic world, attested primarily in Latin votive inscriptions across northern Gaul, parts of the German provinces, Britain and occasional farther finds. In the epigraphic record he is regularly equated with the Roman god Mars (Mars Camulus) and appears to have functioned as a local or tribal protector, especially associated with the Remi of Durocortorum (Reims).
The 'Weeper' of Scottish Highland tradition — an invisible spirit heard wailing near waterfalls before a disaster befalls a clan, a Highland variant of the Irish Banshee.

He is treated in the sources as a human hero whose life is affected by wondrous events (enchantment, serpent-affliction, knightly tests) rather than as an independently supernatural being.
Caradocus (Middle Welsh: Karadawc) is a legendary Cornish ruler attested in medieval pseudo‑histories, principally Geoffrey of Monmouth's Historia regum Britanniae, where he functions as a noble counselor, envoy, and peacemaker in the narrative linking Britain and Magnus Maximus. He is presented as a historical/legendary human figure rather than a supernatural being.
Caradog ap Bran is a legendary Welsh prince, son of Bendigeidfran (Bran the Blessed), known from the Second Branch of the Mabinogi (Branwen ferch Llŷr) and medieval triadic lists.

A monstrous, unusually large cat from Welsh myth later adapted into continental medieval romance (Anglo‑Norman/Old French) as Chapalu/Capalu. Associated with islands, lakes, bogs, and shoreline liminal zones, it functions as a localized animal horror that confronts named heroes (Welsh Cai/Kay; continental sources often transfer the opponent to King Arthur).
Cathbad (Cathbhadh) is a principal druid and seer in the Ulster Cycle of early Irish narrative, famed for pronouncing auspicious timings, naming and raising the infant Conchobar, and prophesying the fates of major figures. In some narrative variants he also appears as leader of a band of fianna and exercises martial violence.
Cathubodua is a theonym known from a single Latin‑script votive altar from Roman‑period Gaul (found near Mieussy, Haute‑Savoie). Modern scholars reconstruct a Proto‑Celtic form *Katu‑bodwā and infer a martial or victory‑related function (comparisons made to the Irish Badb or the Greek Nike), but the inscription itself supplies no narrative or iconography.
Catigern is a legendary/historical early medieval British warrior-prince remembered chiefly for dying fighting the Saxons at the Battle of Epsford/Aylesford. He appears in medieval chronicles and genealogies (notably the Historia Brittonum and various Welsh pedigrees) as a son or kinsman within ruling lineages and is used in later tradition for dynastic legitimation and local topographical memory.
Catskin is the name/title of an English and related folk-tale heroine type (ATU 510B) who escapes an unwanted marriage by disguising herself in a catskin coat.

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).

Ceridwen is an enchantress in medieval Welsh legend, keeper of a cauldron whose brew produces awen (poetic inspiration). In the Tale of Taliesin she brews a potion intended for her son; when her servant Gwion Bach gains the first drops the resulting pursuit, shapeshifting sequence, swallowing and rebirth produce the poet Taliesin. Later sources and modern writers sometimes recast her as a goddess of transformation and rebirth.

Cethlenn (Old Irish Cethlenn/Cethleann/Ceithlenn/Ceithlionn; modern Irish Ceithlinn/Caitlín in some treatments) is a named figure in medieval and early modern Irish narrative tradition associated with the Fomorians. She appears as a prophetess who foretells the downfall of the Fomorians, a martial actor who wounds the Dagda in the Second Battle of Mag Tuired, a mother linked to Ethniu (and thus to Lugh), and an eponymous figure tied to the place-name Enniskillen (Inis Cethlenn).
A changeling is a human-like substitute left by nonhuman beings (fairies, trolls, demons, etc.) after they abduct a human—most often an infant.

The figure is a scholarly reconstruction from hydronymy, regional archaeology (notably a 1967 tricephalic statue near the Clyde), and the widespread Celtic pattern of female water-deities; direct evidence of cult or rites is not preserved in the cited sources.
A small, mine-associated Welsh spirit (plural coblynau or coblynod) that inhabits mines and quarries.
