The image came clear, and it was Willow. She stood alone at the edge of a lake—this lake—and held in her hand the bridle of spun gold that was the vision of her dream. She was clothed in white silk, and her beauty was a radiance that outshone even that created by the music of the player and the dance of the wood nymphs. Flushed with life, her face lifted against the colors that spun about her, and her long green tresses fanned out in the whisper of the wind. She held the bridle out from her as if it were a gift and she waited.

Beware! a voice warned suddenly, a voice so tiny as to be almost lost in the whirl of the vision.

Ben wrenched his eyes momentarily from Willow. From what seemed an impossible distance below, Edgewood Dirk stared up at him.

“What’s wrong?” Ben managed to ask.

But the question was irretrievably lost in what happened next. The music had reached a fever pitch, so intense that it locked away everything. The world was gone. There was only the lake, the whirl of the wood nymphs, and the vision of Willow. Colors flooded Ben’s vision with impossibly bright hues, and there were tears in his eyes. He had never known such happiness. He felt as if he were breaking apart inside and had been transformed.

Then something new appeared at the edge of the lake, beyond the nymphs and the vision of Willow—something at once both impossibly lovely and terrifying. Ben heard the muffled cry of the River Master. It was a cry of fulfillment. The whirl of sound and color shimmered and bent like fabric stretched, and the intrusion from without stepped gingerly into its weave.

It was the black unicorn.

Ben felt his breath catch in his throat. There was a burning in his eyes and a sudden, impossible sense of need. He had never seen anything as beautiful as the unicorn. Even Willow in the vision of the wood nymphs was but a pale shadow next to the fairy creature. Its delicate body seemed to sway with the music and the dance as it emerged from the dark into the sweep of color, and its horn glowed white with the magic of its being.

Then Dirk’s warning came again, no more than a memory this time. Beware!

“What is happening?” Ben whispered.

The River Master turned back to him now, head swinging about in slow motion. The hard face was alive with feelings that danced across its chiseled surface in waves of light and color. He spoke, yet the words seemed to come not from his mouth, but from his mind. “I will have him, High Lord! I will have his magic for my own, and it will become a part of my land and my people! He must belong to me! He must!”

And Ben saw suddenly, through the blanket of pleasant feelings and through the music and the dance, the truth of what the River Master was about. The River Master had not summoned the piper and the wood nymphs for the purpose of discovering anything of Willow or her mother. His ambition was much greater than that. He had summoned piper and nymphs to bring him the black unicorn. He had used music and dance to create the illusion of his daughter and her bridle of spun gold to draw the unicorn to the lakeside where it might be taken. The River Master had believed Ben’s story all right—but he had decided that the black unicorn would better serve his own purposes than the purposes of a dethroned and powerless King. He had taken Willow’s dream and made it his own. This whole business was an elaborate charade—the piper and the wood nymphs and the instruments used to create it.
