And to the high sunny nursery Lirazel would come, bringing a brightness that the learned witch had not in all her spells, and would sing to her boy those songs that none can sing to us here, for they were learned the other side of the frontier of twilight and were made by singers all unvexed by Time. And for all the marvel that there was in those songs, whose origin was so far from the fields we know, and in times remote from those that historians use; and though men wondered at the strangeness of them when from open casements through the Summer days they drifted over Erl; yet none wondered even at those as she wondered at the earthly ways of her child and all the little human things that he did more and more as he grew. For all human ways were strange to her. And yet she loved him more than her father's realm, or the glittering centuries of her ageless youth, or the palace that may be told of only in song. In those days Alveric learned that she would never now grow familiar with earthly things, never understand the folk that dwelt in the valley, never read wise books without laughter, never care for earthly ways, never feel more at ease in the Castle of Erl than any woodland thing that Threl might have snared and kept caged in a house. He had hoped that soon she would learn the things that were strange to her, till the little differences that there are between things in our fields and in Elfland should not trouble her any more; but he saw at last that the things that were strange would always so remain, and that all the centuries of her timeless home had not so lightly shaped her thoughts and fancies that they could be altered by our brief years here. When he had learned this he had learned the truth. Between the spirits of Alveric and Lirazel lay all the distance there is between Earth and Elfland; and love bridged the distance, which can bridge further than that; yet when for a moment on the golden bridge he would pause and let his thoughts look down at the gulf, all his mind would grow giddy and Alveric trembled. What of the end, he thought? And feared lest it should be stranger than the beginning.
