"I know that," said the little woman, "and it's because of your love for each other, and because her mother was a friend to me in the days gone by, that I have come here to try and help you; but there is not much time for talking, the night advances. At the bank below a boat awaits you. Step into it and it will lead you to the mainland, and when you reach it you will find before you a path that will take you to the green fields of Erin and the plains of Tara. I know you will have to face danger. I know not what kind of danger; but whatever it may be do not draw your sword before you tread upon the mainland, for if you do you shall never reach it, and the boat will come back again to the floating island; and now go and may luck go with you;" and saying this the little woman climbed up the moonbeams and disappeared.
The prince left the palace and descended to the lake, and there before him he saw a glistening boat; he stepped into it, and the boat went on and on beneath the moon, and at last he saw the mainland, and he could trace a winding pathway going away from the shore. The sight filled his heart with joy, but suddenly the milk-white moonshine died away, and looking up to the sky he saw the moon turning fiery red, and the waters of the lake, shining like silver a moment before, took a blood-red hue, and a wind arose that stirred the waters, and they leaped up against the little boat, tossing it from side to side. While Cuglas was wondering at the change, he heard a strange, unearthly noise ahead of him, and a bristling monster, lifting its claws above the water, in a moment was beside the boat and stuck one of his claws in the left arm of the prince, and pierced the flesh to the bone. Maddened by the pain the prince drew his sword and chopped off the monster's claw. The monster disappeared beneath the lake, and, as it did so, the color of the water changed, and the silver moonlight shone down from the sky again, but the boat no longer went on towards the mainland, but sped back towards the floating island, while forth from the island came a fleet of fairy boats to meet it, led by the shallop of the fairy queen. The queen greeted the prince as if she knew not of his attempted flight, and to the music of the harps the fleet returned to the palace.
The next day passed and the night came, and again the prince was lying on the couch, thinking of the Princess Ailinn, and again he saw the shadow on the floor and heard the tapping against the window.
And when he opened it the little woman slid into the room.
"You failed last night," she said, "but I come to give you another chance. To-morrow the queen must set out on a visit to her fairy kinsmen, who dwell in the green hill near the plain of Tara; she cannot take you with her, for if your feet once touched the green grass that grows in the fruitful fields of Erin, she could never bring you back again. And so, when you find she has left the palace, go at once into the banquet hall and look behind the throne, and you will see a small door let down into the ground. Pull this up and descend the steps which you will see. Where they lead to I cannot tell. What dangers may be before you I do not know; but this I know, if you accept anything, no matter what it is, from anyone you may meet on your way, you shall not set foot on the soil of Erin."
And having said this the little woman, rising from the floor, floated out through the window.
The prince returned to his couch, and the next morning, as soon as he heard the queen had left the palace, he hastened to the banquet hall. He discovered the door and descended the steps, and he found himself in a gloomy and lonesome valley. Jagged mountains, black as night, rose on either side, and huge rocks seemed ready to topple down upon him at every step. Through broken clouds a watery moon shed a faint, fitful light, that came and went as the clouds, driven by a moaning wind, passed over the valley.
Cuglas, nothing daunted, pushed on boldly until a bank of cloud shut out completely the struggling moon, and closing over the valley covered it like a pall, leaving him in perfect darkness. At the same moment the moaning wind died away, and with it died away all sound. The darkness and the deathlike silence sent an icy chill to the heart of Cuglas. He held his hand close to his eyes, but he saw it not. He shouted that he might hear the sound of his own voice, but he heard it not. He stamped his foot on the rocky ground, but no sound was returned to him. He rattled his sword in its brazen scabbard, but it gave no answer back to him. His heart grew colder and colder, when suddenly the cloud above him was rent in a dozen places, and lightning flashed through the valley, and the thunder rolled over the echoing mountains. In the lurid glare of the lightning Cuglas saw a hundred ghostly forms sweeping towards him, uttering as they came nearer and nearer shrieks so terrible that the silence of death could more easily be borne. Cuglas turned to escape, but they hemmed him round, and pressed their clammy hands upon his face.
With a yell of horror he drew his sword and slashed about him, and that very moment the forms vanished, the thunder ceased, the dark cloud passed, and the sun shone out as bright as on a summer day, and then Cuglas knew the forms he had seen were those of the wild people of the glen.[7]
With renewed courage he pursued his way through the valley, and after three or four windings it took him out upon a sandy desert. He had no sooner set foot upon the desert than he heard behind him a crashing sound louder than thunder. He looked around, and he saw that the walls of mountain through which he had just passed had fallen into the valley, and filled it up so that he could no longer tell where it had been.
