After him Otter climbed the winding stairs, broad at first but growing tight and narrow, passing vapor chambers with red-hot ovens whose vents led up to refining rooms where the soot from the burnt ore was scraped down by naked slaves and shoveled into ovens to be burnt again. They came to the topmost room. Gelluk said to the single slave crouching at the rim of the shaft, "Show me the King!"

The slave, short and thin, hairless, with running sores on his hands and arms, uncapped a stone cup by the rim of the condensing shaft. Gelluk peered in, eager as a child. "So tiny," he murmured. "So young. The tiny Prince, the baby Lord, Lord Turres. Seed of the world! Soul-jewel!"

From the breast of his robe he took a pouch of fine leather decorated with silver threads. With a delicate horn spoon tied to the pouch he lifted the few drops of quicksilver from the cup and placed them in it, then retied the thong.

The slave stood by, motionless. All the people who worked in the heat and fumes of the roaster tower were naked or wore only breechclout and moccasins. Otter glanced again at the slave, thinking by his height he was a child, and then saw the small breasts. It was a woman. She was bald. Her joints were swollen knobs in her bone-thin limbs. She looked up once at Otter, moving her eyes only. She spat into the fire, wiped her sore mouth with her hand, and stood motionless again.

"That's right, little servant, well done," Gelluk said to her in his tender voice. "Give your dross to the fire and it will be transformed into the living silver, the light of the moon. Is it not a wonderful thing," he went on, drawing Otter away and back down the spiral stair, "how from what is most base comes what is most noble? That is a great principle of the art! From the vile Red Mother is born the Allking. From the spittle of a dying slave is made the silver Seed of Power."

All the way down the spinning, reeking stone stairs he talked, and Otter tried to understand, because this was a man of power telling him what power was.

But when they came out into the daylight again his head kept on spinning in the dark, and after a few steps he doubled over and vomited on the ground.

Gelluk watched him with his inquisitive, affectionate look, and when Otter stood up, wincing and gasping, the wizard asked gently, "Are you afraid of the King?"

Otter nodded.

"If you share his power he won't harm you. To fear a power, to fight a power, is very dangerous. To love power and to share it is the royal way. Look. Watch what I do." Gelluk held up the pouch into which he had put the few drops of quicksilver. His eye always on Otter's eye, he unsealed the pouch, lifted it to his lips, and drank its contents. He opened his smiling mouth so that Otter could see the silver drops pooling on his tongue before he swallowed.

"Now the King is in my body, the noble guest of my house. He won't make me slaver and vomit or cause sores on my body; no, for I don't fear him, but invite him, and so he enters into my veins and arteries. No harm comes to me. My blood runs silver. I see things unknown to other men. I share the secrets of the King. And when he leaves me, he hides in the place of ordure, in foulness itself, and yet again in the vile place he waits for me to come and take him up and cleanse him as he cleansed me, so that each time we grow purer together." The wizard took Otter's arm and walked along with him. He said, smiling and confidential, "I am one who shits moonlight. You will not know another such. And more than that, more than that, the King enters into my seed. He is my semen. I am Turres and he is me…"

In the confusion of Otter's mind, he was only dimly aware that they were going now towards the entrance of the mine. They went underground. The passages of the mine were a dark maze like the wizard's words. Otter stumbled on, trying to understand. He saw the slave in the tower, the woman who had looked at him. He saw her eyes.

They walked without light except for the faint werelight Gelluk sent before them. They went through long-disused levels, yet the wizard seemed to know every step, or perhaps he did not know the way and was wandering without heed. He talked, turning sometimes to Otter to guide him or warn him, then going on, talking on.

They came to where the miners were extending the old tunnel. There the wizard spoke with Licky in the flare of candles among jagged shadows. He touched the earth of the tunnel's end, took clods of earth in his hands, rolled the dirt in his palms, kneading, testing, tasting it. For that time he was silent, and Otter watched him with staring intensity, still trying to understand.

Licky came back to the barracks with them. Gelluk bade Otter goodnight in his soft voice. Licky shut him as usual into the brick-walled room, giving him a loaf of bread, an onion, a jug of water.

Otter crouched as always in the uneasy oppression of the spellbond. He drank thirstily. The sharp earthy taste of the onion was good, and he ate it all.

As the dim light that came into the room from chinks in the mortar of the bricked-up window died away, instead of sinking into the blank misery of all his nights in that room, he stayed awake, and grew more awake. The excited turmoil of his mind all the time he had been with Gelluk slowly quieted. From it something rose, coming close, coming clear, the image he had seen down in the mine, shadowy yet distinct: the slave in the high vault of the tower, that woman with empty breasts and festered eyes, who spat the spittle that ran from her poisoned mouth, and wiped her mouth, and stood waiting to die. She had looked at him.

He saw her now more clearly than he had seen her in the tower. He saw her more clearly than he had ever seen anyone. He saw the thin arms, the swollen joints of elbow and wrist, the childish nape of her neck. It was as if she was with him in the room. It was as if she was in him, as if she was him. She looked at him. He saw her look at him. He saw himself through her eyes.

He saw the lines of the spells that held him, heavy cords of darkness, a tangled maze of lines all about him. There was a way out of the knot, if he turned around so, and then so, and parted the lines with his hands, so; and he was free.

He could not see the woman any more. He was alone in the room, standing free.

All the thoughts he had not been able to think for days and weeks were racing through his head, a storm of ideas and feelings, a passion of rage, vengeance, pity, pride.

At first he was overwhelmed with fierce fantasies of power and revenge: he would free the slaves, he would spellbind Gelluk and hurl him into the refining fire, he would bind him and blind him and leave him to breathe the fumes of quicksilver in that highest vault till he died… But when his thoughts settled down and began to run clearer, he knew that he could not defeat a wizard of great craft and power, even if that wizard was mad. If he had any hope it was to play on his madness, and lead the wizard to defeat himself.

He pondered. All the time he was with Gelluk, he had tried to learn from him, tried to understand what the wizard was telling him. Yet he was certain, now, that Gelluk's ideas, the teaching he so eagerly imparted, had nothing to do with his power or with any true power. Mining and refining were indeed great crafts with their own mysteries and masteries, but Gelluk seemed to know nothing of those arts. His talk of the Allking and the Red Mother was mere words. And not the right words. But how did Otter know that?

In all his flood of talk the only word Gelluk had spoken in the Old Tongue, the language of which wizards' spells were made, was the word turres. He had said it meant semen. Otter's own gift of magery had recognized that meaning as the true one. Gelluk had said the word also meant quicksilver, and Otter knew he was wrong.
