The King of Elfland's Daughter by Lord Dunsany

Northward to lonely lands through wearying years Alveric wandered, where windy fragments of his grey gaunt tent added a gloom to chill evenings. And the folk upon lonely farms, as they lit the lights in their houses, and the ricks began to darken against the pale green of the sky, would sometimes hear the rap of the mallets of Niv and Zend coming clear through the hush from the land that no others trod. And their children peering from casements to see if a star was come would see perhaps the queer grey shape of that tent flapping its tatters above the last of the hedgerows, where a moment before was only the grey of the gloaming. On the next morning there would be guesses and wonderings, and the joy and fear of the children, and the tales that their elders told them, and the explorations by stealth to the edge of the fields of men, shy peerings through dim green gaps in the last of the hedgerows (though to look toward the east was forbidden), and rumours and expectations; and all these things were blended together by this wonder that came from the east, and so passed into legend, which lived for many a year beyond that morning; but Alveric and his tent would be gone.

So day by day and season after season that company wandered on, the lonely mateless man, the moonstruck lad and the madman, and that old grey tent with its long twisted pole. And all the stars became known to them, and all the four winds familiar, and rain and mist and hail, but the flow of yellow windows all warm and welcome at night they knew only to say farewell to: with the earliest light in the first chill of dawn Alveric would awake from impatient dreams, and Niv would arise shouting, and away they would go upon their crazed crusade before any sign of awakening appeared on the quiet dim gables. And every morning Niv prophesied that they would surely find Elfland; and the days wore away and the years.
