But the Irish peasant still sees them flitting by his path in the evening light, or dancing on the meadow round the grassy mound, singing and playing strange melodies; or mourns for the child they have carried away to live with them and forget her people, or watches with fear his dreaming daughter who has been touched by them, and is never again quite a child of this earth, or quite of the common race of man.
These were the invisible lands and peoples of the Irish imagination; and they live in and out of many of the stories.

Cuchulain is lured into a fairy-land, and lives for more than a year in love with Fand, Mananan's wife.

Into another fairy-land, through zones of mist, Cormac, as is told here, was lured by Mananan, who now has left the sea to play on the land.

Oisin, as I have already said, flies with Niam over the sea to the island of Eternal Youth.

Etain, out of the immortal land, is born into an Irish girl and reclaimed and carried back to her native shore by Midir, a prince of the Fairy Host.
