The King of Elfland's Daughter by Lord Dunsany

As Alveric hastened back, led by two madmen, to those lands over which he had long ago been lord, the horns of Elfland had sounded in Erl all day. And though only Orion heard them, they no less thrilled the air, flooding it deep with their curious golden music, and filling the day with a wonder that others felt; so that many a young girl leaned from her window to see what was enchanting the morning. But as the day wore on the enchantment of the unheard music dwindled, giving place to a feeling that weighed on all minds in Erl and seemed to bode the imminence of some unknown region of wonder. All his life Orion had heard these horns blowing at evening except upon days on which he had done ill: if he heard the horns at evening he knew that it was well with him. But now they had blown in the morning, and blew all day, like a fanfare in front of a march; and Orion looked out of his window and saw nothing, and the horns rang on, proclaiming he knew not what. Far away they called his thoughts from the things of Earth that are the concern of men, far away from all that casts shadows. He spoke to no man that day, but went among his trolls and such elfin things as had followed them over the border. And all men that saw him perceived such a look in his eyes as showed his thoughts to be far in realms that they dreaded. And his thoughts were indeed far thence, once more with his mother. And hers were with him, lavishing tendernesses that the years had denied her, in their swift passage over our fields that she never had understood. And somehow he knew she was nearer.

And all that strange morning the will-o'-the-wisps were restless and the trolls leaped wildly all about their lofts, for the horns of Elfland tinged all the air with magic and excited their blood although they could not hear them. But towards evening they felt impending some great change and all grew silent and moody. And something brought to them yearnings for their far magical home, as though a breeze had blown suddenly into their faces straight off the tarns of Elfland; and they ran up and down the street looking for something magical, to ease their loneliness amongst mundane things. But found nothing resembling the spell-born lilies that grew in their glory above the elfin tarns. And the folk of the village perceived them everywhere and longed for the wholesome earthly days again that there were before the coming of magic to Erl. And some of them hurried off to the house of the Freer and took refuge with him amongst his holy things from all the unhallowed shapes that there were in their streets and all the magic that tingled and loomed in the air. And he guarded them with his curses which floated away the light and almost aimless will-o'-the-wisps, and even, at a short distance, awed the trolls, but they ran and capered only a little way off. And while the little group clustered about the Freer, seeking solace from him against whatever impended, with which the air was growing tenser and grimmer as the short day wore on, there went others to Narl and the busy elders of Erl to say "See what your plans have done. See what you have brought on the village."
