“Run,” the magician said. He made a frantic, foolish, flying leap and landed on Rukh’s back, hugging the dark man dumb and blind with his long arms. They fell together, and Schmendrick scrambled up first, his knees nailing Rukh’s shoulders to the earth. “Barbed wire,” he gasped. “You pile of stones, you waste, you desolation, I’ll stuff you with misery till it comes out of your eyes. I’ll change your heart into green grass, and all you love into a sheep. I’ll turn you into a bad poet with dreams. I’ll set all your toenails growing inward. You mess with me.”

Rukh shook his head and sat up, hurling Schmendrick ten feet away. “What are you talking about?” He chuckled. “You can’t turn cream into butter.” The magician was getting to his feet, but Rukh pushed him back down and sat on him. “I never did like you,” he said pleasantly. “You give yourself airs, and you’re not very strong.” Heavy as night, his hands closed on the magician’s throat.

The unicorn did not see. She was out at the farthest cage, where the manticore growled and whimpered and lay flat. She touched the point of her horn to the lock, and was gone to the dragon’s cage without looking back. One after another, she set them all free‌—‌the satyr, Cerberus, the Midgard Serpent. Their enchantments vanished as they felt their freedom, and they leaped and lumbered and slithered away into the night, once more a lion, an ape, a snake, a crocodile, a joyous dog. None of them thanked the unicorn, and she did not watch them go.

Only the spider paid no mind when the unicorn called softly to her through the open door. Arachne was busy with a web which looked to her as though the Milky Way had begun to fall like snow. The unicorn whispered, “Weaver, freedom is better, freedom is better,” but the spider fled unhearing up and down her iron loom. She never stopped for a moment, even when the unicorn cried, “It’s really very attractive, Arachne, but it’s not art.” The new web drifted down the bars like snow.

Then the wind began. The spiderweb blew across the unicorn’s eyes and disappeared. The harpy had begun to beat her wings, calling her power in, as a crouching wave draws sand and water roaring down the beach. A bloodshot moon burst out of the clouds, and the unicorn saw her‌—‌swollen gold, her streaming hair kindling, the cold, slow wings shaking the cage. The harpy was laughing.

In the shadow of the unicorn’s cage, Rukh and Schmendrick were on their knees. The magician was clutching the heavy ring of keys, and Rukh was rubbing his head and blinking. Their faces were blind with terror as they stared at the rising harpy, and they leaned together in the wind. It blew them against one another, and their bones rang.

The unicorn began to walk toward the harpy’s cage. Schmendrick the Magician, tiny and pale, kept opening and closing his mouth at her, and she knew what he was shrieking, though she could not hear him. “She will kill you, she will kill you! Run, you fool, while she’s still a prisoner! She will kill you if you set her free!” But the unicorn walked on, following the light of her horn, until she stood before Celaeno, the Dark One.
