Possession by A.S. Byatt

little man, “I will take the pretty glass key.” And the little man answered, “You have chosen not with prudence, but with daring. The key is the key to an adventure, if you will go in search of it.”
    “Why not?” replied the tailor. “Since there is no use for my craft in this wild place, and since I have not chosen prudently.”
    Then the animals came closer with their warm, milky breaths that smelled sweetly of hay and the summer, and their mild comforting gaze that was not human, and the dog lay with his heavy head on the tailor’s foot, and the brindled cat sat on the arm of his chair.
    “You must go out of this house,” said the little grey man, “and call to the West Wind, and show her your key, when she comes, and let her carry you where she will, without struggle or alarm.If you fight or question she will toss you on the thorns and it will go ill with you before you come out of there. If she will take you, you will be set down in a bare heath, on a great stone, which is made of granite and is the gate to your adventure, though it will seem to have been fixed and unmoving since the making of the world. On this stone you must lay a feather from the tail of the cockerel here, which he will willingly give you, and the door will be opened to you. You must descend without fear, or hesitation, and descend further, and still descend; you will find that your glass key will shed light on your way if you hold it before you. In time you will come to a stone vestibule, with two doors leading to branching passages you must not follow, and a low curtained door leading on and downwards. You must not touch this curtain with your hand, but must lay on it the milk-white feather which the hen will give you, and the curtain will be opened silently, by unseen hands, and the doors beyond it will lie open, and you may come into the hall where you shall find what you shall find.”
    “Well, I will adventure,” said the little tailor, “though I have great fear of the dark places under the earth, where there is no light of day and what is above is dense and heavy.” So the cock and the hen allowed him to take a glistening burnished black and emerald feather and a soft creamy-white feather, and he bade them all good bye and went into the clearing, and called to the West Wind, holding up his key.
    And that was a delightful and most alarming sensation, when the long, airy arms of the West Wind reached down through the trees and caught him up, and the leaves were all shivering and clattering and trembling with her passing, and the straws danced before the house and the dust rose and flew about in little earth-fountains. The trees grabbed at him with twiggy fingers as he rose up through them, lurching this way and that in the gusts, and then he felt himself held against the invisible rushing breast of the long Wind, as she hurled moaning along the sky. He rested his face against his airy pillow, and did not cry out or struggle, and the sighing song of the West Wind, full of fine rain and glancing sunshine, streaming clouds and driven starlight, netted him around and around.
    She put him down as the little grey man had foretold on a huge grey granite stone, pitted and scarred and bald. He heard her whisking and wailing on her way, and he bent down and laid the cock-feather on the stone, and behold with a heavy groaning and grinding the huge stone swung up in the air and down in the earth, as though on a pivot or balance, disturbing waves of soil and heather like thick sea-water, and showing a dark, dank passage under the heather-roots and the knotty roots of the gorse. So in he went, bravely enough, thinking all the time of the thickness of rock and peat and earth over his head, and the air in that place was chill and damp and the ground underfoot was moist and sodden. He bethought him of his little key and held it up bravely before him, and it put out a little sparkling light that illumined a step at a time, silvery-pale. So he
