About Fomorian names

The Fomorians (Old Irish Fomoire) are the sea-raiding enemies of Ireland's early settlers in the medieval Irish texts. In the Book of Invasions they tax the people of Nemed from Conand's tower, and in the Second Battle of Mag Tuired the host of Balor and Indech is broken by the Tuatha Dé Danann. Tabletop games borrowed the word for a race of cursed giants of the deep caves and the fey realm.

The texts name only a small number of Fomorians, and this list holds 21 of them: Balor, Bres, Elatha, Tethra, Indech, Cichol Gricenchos, Conand, Morc, Ethniu, Cethlenn, Octriallach, Dolb, Lóch Lethglas, Goll, Irgoll, Gann, Sengann, Omna, Bagna, Tuire Tortbuillech and Loscennlomm. Everything else among the 1,000 names is invented in the Old Irish style: early Irish personal names and words given a patronymic, a byname or an English epithet. They are names for your own giants, not figures from the myths.

The originals come in several styles: kings with patronymics, raider chieftains, tower lords of the northern isles, queens and sorceresses, tribute collectors, smiths and druids, cursed cave and fey giants for fantasy campaigns, and short harsh one-word names. A patronymic that points at an attested Fomorian, such as mac Tethrach, is an invented kinship too.

How to choose Fomorian names

  • Keep the attested names for the figures themselves. Balor, Tethra or Cethlenn work best as legends your giants boast about, not as a random raider on the beach.
  • Show rank through structure. A bare harsh name such as Trethan or Díberg suits a rank-and-file giant, while a patronymic like Bressal mac Tethrach or a title like Sea-King Dúnechaid marks a ruler.
  • Match the epithet to the setting: sea and tower epithets for a mythic Irish coast, curse and cavern epithets such as Temel the Accursed for an underground lair, thorn and twilight ones such as Dris the Briar-King for a fey realm.
  • Read mac as son of, ua as grandson of and ingen as daughter of. The word that follows is a genitive form, so keep the pair together instead of swapping in another name.
  • For reading aloud at the table, an accent marks a long vowel, c is always hard, and ch is the sound at the end of loch.

Frequently asked questions

Which Fomorian names in the list come from the Irish texts?

Twenty-one figures: Balor, Bres, Elatha, Tethra, Indech, Cichol Gricenchos, Conand, Morc, Ethniu, Cethlenn, Octriallach, Dolb, Lóch Lethglas, Goll, Irgoll, Gann, Sengann, Omna, Bagna, Tuire Tortbuillech and Loscennlomm. Seven of them appear a second time in a longer form the texts give, such as Bres mac Elathan and Balor Birugderc. Every other name is original.

Are the other names real Old Irish names?

They are built from real material, but they are inventions. Some take early Irish personal names such as Bressal or Gormlaith, others turn Old Irish words into names, like Serb (bitter), Dorn (fist) and Tonn (wave), and most add an epithet. No medieval text calls any of them a Fomorian, and a few are loose coinages that a scholar of the language would spell differently.

Can I use these names for D&D fomorians?

Yes. The game's fomorians are cursed giants of the Underdark and the Feywild, and part of the list is written with them in mind: Temel the Accursed, Derc of the Lightless Lake, Scíach the Once-Fair. These were drafted for this list and not taken from a rulebook or a published adventure.

What do mac, ua and ingen mean in a Fomorian name?

In Old Irish mac is son of, ua is grandson of and ingen is daughter of, each followed by the ancestor's name in the genitive: Elatha becomes Elathan in Bres mac Elathan. Invented patronymics in the list, such as Dúnlaith ingen Tethrach, copy that grammar and are not kinships found in the myths.
