Character Name

Sadhbh

Meaning — From the Old Irish "sadb" meaning "sweet" or "goodly". In Irish mythology, Sadhbh is the mother of Oisín: she was transformed into a deer by the Dark Druid Fear Doirc and returned to human form when she entered the protection of Fionn mac Cumhaill. Their son Oisín ("little fawn") was born while she was again in deer form after she was recaptured. The name carries both gentleness and the tragedy of transformation.·Old Irish origin·Female·SIVE (rhymes with "five")

Sadhbh Sadhbh carries the quality of gentleness under siege — a sweetness that the world repeatedly tries to transform into something lesser, and a resilience that preserves the essential self through those transformations. Characters with this name are often at the centre of stories about love separated by circumstance, about the cost exacted by those who cannot bear to see goodness flourish freely.

Derived from the Old Irish "aoibh" meaning "beauty", "pleasantness", or "radiance", with the suffix "-eann" indicating a feminine bearer of that quality.

Several figures in Irish mythology bear this name, and it is associated with otherworldly beauty and gentleness.

Fionn

Derived from the Old Irish "find" meaning "white", "fair", or "fair-haired". It is one of the most celebrated names in Irish mythology as the given name of Fionn mac Cumhaill, the legendary leader of the Fianna warrior band.

Fionn

The feminine use of Fionn, from Old Irish "find" meaning "white", "fair", or "fair-haired". While predominantly a masculine name in mythology, Fionn has been used for girls in Ireland, carrying the same meanings of fairness and brightness. The name connects bearers to one of Ireland's most celebrated mythological figures while the feminine use gives it a distinctive cross-gender quality.

Donal

From the Old Irish "Domhnall", composed of the Celtic elements "dubno" (world) and "val" (rule), meaning "ruler of the world". This was an extremely common name among Irish and Scottish kings and chieftains — multiple High Kings of Ireland bore the name, as did numerous Scottish monarchs and clan chiefs. The name projects both worldly authority and a specifically Celtic conception of kingship as stewardship of the land.

Nessa

Of uncertain Old Irish etymology, possibly related to "ness" meaning "rough" or "wild". In the Ulster Cycle, Nessa was the mother of King Conchobar mac Nessa — his name means literally "son of Nessa" — a woman of great political cunning who manipulated the hero Fergus mac Róich into surrendering his kingship to her son by agreeing to marry Fergus only on condition he let Conchobar reign for a year.
