The Fomorian Abyss
Domnu is the deep from which the Fomorians draw their power. Her name means exactly that — deep, hollow, abyss. The Fir Domnainn, the “peoples of the deep,” are named after her. Indech, one of the principal Fomorian kings at the Second Battle of Mag Tuired, carries her name in his title: mac Dé Domnann, son of the god of the deep.
She is not a figure who appears in events. She is more like a force — the dark, cold depth beneath the ordered world, the primordial abyss that the Fomorians come from and carry with them. Where Danu or Anu is the flowing abundance from which the Tuatha Dé emerge, Domnu is the descent, the hollow, the thing beneath the surface.
The Fomorians came from the sea, from beneath it, from the oldest and deepest places. Domnu is what that means.
