Indech mac Dé Domnann – Irish Samhain Mythology & the Tide of Shadow

Updated: Nov 27, 2025

“When the year’s light wanes, my power rises with the tide.”


Wind-blown fire on wild grass with ancient standing stones in the background, evoking an Irish battlefield.

When the veil thins and the old year dies, a dark tide stirs beneath the land.

It is the power of Indech mac Dé Domnann, the shadowed king of the Fomorians — the ancient beings of sea and storm who opposed the Tuatha Dé Danann.

Indech is the embodiment of decline, destruction, and sacred balance — the force that brings endings so that renewal may come.


In Irish Samhain mythology, when the sun’s strength fades and the earth turns inward, his spirit moves through the land once more. He is not the enemy of life, but its necessary balance — the dark current that draws all things back into the depths before they can rise again renewed.



The Fomorian King of Shadow


Indech mac Dé Domnann appears in the Cath Maige Tuired, the Second Battle of Mag Tuired, where the Fomorians and the Tuatha Dé Danann clashed for dominion over Ireland.

He was a king of the sea-born Fomorians, brother to Elatha and father to Octriallach — beings both divine and monstrous, representing the raw, untamed forces of nature.


The battle between the Fomorians and the Tuatha was more than a war of gods — it was the eternal struggle between order and chaos, light and darkness, summer and winter.

When Indech fell, his blood soaked into the soil, feeding the fertility of the land. The myth tells that his death nourished the ground itself, ensuring that life would return after the dark season — a poetic echo of Samhain’s deepest mystery.


In his fall, Indech gave a final gift: renewal through sacrifice.
