Character Name

Diarmait

Meaning — The original Old Irish spelling of Diarmuid, from elements possibly meaning "without envy" from "di" (without) and "airmit" (jealousy or envy). Diarmait mac Cerbaill was the last High King of Ireland to hold the ancient pagan ceremony of the "Feis Temro" (Feast of Tara) around 560 AD. The name appears across Irish history and mythology and reflects the older, more austere orthographic tradition.·Old Irish origin·Male·DEER-mit

Diarmait Diarmait in its older spelling projects the archaic authority of the early Irish kingdom — a name for characters deeply embedded in the pre-Norman Gaelic world, defined by an older code of honour and a fiercer, less mediated relationship with the land and its gods. Characters named Diarmait tend to be formidably masculine in the old heroic manner, passionate and loyal with an intensity that admits no half-measures.

Niall

An Old Irish name of debated etymology — most scholars derive it from a Proto-Celtic root meaning "champion", "cloud", or possibly "passionate". It is most famously borne by Niall of the Nine Hostages (Niall Noígíallach), the legendary High King of Ireland from around the 4th–5th century whose descendants, the Uí Néill dynasty, dominated Irish politics for centuries. Genetic studies suggest a remarkable proportion of men with Irish heritage descend from him.

Fearghal

From the Old Irish "Fearghall" or "Fergal", composed of "fear" (man) and "gal" (valour, ferocity), meaning "man of valour" or "super-valour". The name was borne by Fergal mac Máele Dúin, King of Ireland from 710 to 722 AD, and by Saint Fergal (Virgilius) of Salzburg — an Irish monk who became Bishop of Salzburg and controversially taught that the Earth was spherical, centuries before it was widely accepted in Europe.

Caoilfhinn

Compound Old Irish name from "caol" (slender, narrow) and "fionn" (white, fair, blessed). The name combines physical grace with the light-filled beauty implied by "fionn". It is an authentically traditional Irish name that represents the layered compound structure common in early medieval Irish personal naming. Several saints and noblewomen in medieval Irish records bear this name.

Ciara

Derived from the Old Irish "ciar" meaning "dark", "black", or "dark-haired". Saint Ciara of Kilkeary was a sixth-century Irish saint, and the name appears throughout early Irish ecclesiastical records. The meaning reflects an older Celtic aesthetic that prized dark colouring, and the same root gives the male name Ciarán, meaning "little dark one".
