“You can relax now.”

Arvin sagged onto the ground and let the tension flow from his muscles. Sitting up, he tilted his head to stretch his neck. “I did it,” he said. “I learned a new power.”

“Yes.” Zelia stared at him with a thoughtful expression, as if his success had surprised her. “That’s enough for one night,” she said curtly. “It’s almost Middark. I must see if the cultists have returned to the chamber.”

Arvin nodded, suddenly exhausted. Trembling slightly, he pulled his clothes back on. He’d expected the invigorating rush of energy to continue, but all he wanted to do was sleep. He hoped the headache would let him. When he’d finished dressing, he sat again, his back against one of the potted plants. He found himself fighting to keep his eyes open. Even his curiosity about what Zelia was doing-sinking into a cross-legged position with the soles of her feet uppermost, just as his mother had done when she meditated-couldn’t keep him awake.

As Zelia stared off into the night sky, hissing as she summoned up the psionic power that would let her peer into the sewer chamber, he fell asleep…

And into the strangest dream.

23 Kythorn, Middark

Arvinlay on his side, knees drawn up to his chest and arms coiled around his legs. He was midway between sleep and wakefulness-aware that he lay on a rooftop, his breaths slow and even as they hissed in and out of his mouth, yet with his mind entangled in the strands of a dream. It was a strange sensation, almost as if he were awake and observing the dream from a distance-a dream that was as vivid as waking.

In the dream he was a child-a serpent child. He was slithering down a corridor as fast as he could, contractions rippling through his body as he pushed with his scales against the smooth green stone of the floor. Behind him loomed a human child of about five years of age-two years younger than Arvin-with braided hair and a slave brand on her cheek. She was laughing as she chased Arvin into a carpeted dining hall, her eyes glittering with excitement. Arvin, hissing with delight at having eluded the lumbering human, heaved the front half of his torso upright and began to slither up onto a table. Too late. The slave girl bent down and yanked the carpet, sending Arvin tumbling. Then she leaped forward and slapped his tail with her palm.

“Tag the tail!” she shrilled. “Tag the tail and you’re it!”

Arvin felt rage course through him. No. It wasn’t fair-the slave had cheated. She hadn’t given him enough of a start. His body drew back into a coil; then he lashed out. His fangs sank into the girl’s arm, and he tasted the sweet, hot tang of blood.

The slave girl gave a strangled gasp and staggered backward, staring at the twin beads of blood on her forearm, then collapsed onto the floor. “I thought…” she gasped, her tongue already thickening in her mouth. “We… friends…” Then her eyes glazed.

Arvin’s tongue flickered in and out of his mouth. The slave girl lay still on the floor, no longer breathing. Dead.

Regret trickled through him. Perhaps he shouldn’t have been so hasty. Who was he going to play with, now?

Arvin shifted, turning over in his sleep. The night air was growing cooler, less muggy. He squirmed over to a section of rooftop that retained a little of the day’s warmth; his body drank it in. A part of him realized that he had moved like a snake, undulating hips and shoulders in order to shift himself…

The dream shifted. Now Arvin was kneeling on a low stone platform in the middle of a room richer than any he had ever seen. It had a high, domed ceiling held up by gilded columns, windows draped with silk curtains that fluttered in the evening breeze, and walls painted with Origin frescos-a series of images showing the “World Serpent looking down upon the snakes, lizards, and other reptilian races issuing from Her cloaca.

Arvin was weary with the exhaustion that follows an intense rage. His hands were raw from having pounded his fists repeatedly against his sleeping platform, and his skin was moist and itching from the acidic sweat that had oozed out between his scales. He’d hissed until his jaw ached, thrown his dinner against the door-splatters of egg and shell clung to its polished wood-and still his mother hadn’t relented. He was not going to be given another slave with whom to play. Not until he learned to coil his temper. Until he learned to master his emotions. Until he stopped acting so human.

That had punctured his pride. Humans were stupid, blundering creatures. Look how the yuan-ti manipulated and dominated them, just as humans and the other lesser races dominated animals. It was the natural order of things. It-

The door opened. Arvin looked up at the strangest human he’d ever seen. The man was short, dark skinned, and bald-and so wrinkled his face looked as though it had shrunk beneath its skin. Yet he was lean and well muscled. His only article of clothing was a loincloth, nearly as dark as he was. Around one wrist was coiled a finger-thin turquoise serpent with translucent yellow wings: a flying snake from the jungles of Chult. Arvin stared at it, transfixed, as it raised its head and hissed. He’d wanted one of those for so long…

The bald man moved his hand up and down, causing the flying snake to flutter its wings. All the while, he stared at Arvin, not speaking.

In a distant part of the family manse, Arvin heard a wind chime tinkling. Yet the breeze that had been ruffling his curtains had stopped. The clouds must have cleared; sunlight was shining in through the window now.

“Desire,” the bald man said in a deep voice that was at odds with his thin frame. “I can feel it radiating from you, like heat from a sun-warmed rock. Your emotions run deep and swift-very unusual, in a yuan-ti.”

Arvin stared at the impudent human, wondering when he was going to hand over the flying snake-perhaps he should just take it from the man, instead. The pet was obviously an apology from his mother for her overreaction about the slave girl.

The bald man raised his free hand and flicked a fingertip against the snake’s nose. The tiny serpent recoiled, hissing. He flicked its nose again, and this time the snake bared its fangs. Arvin stared, appalled, as the man gave the snake’s nose another flick, sending it lashing back and forth. He flicked his finger at it again, and again, and again, until Arvin was certain the snake would sink its fangs into the offending human at any moment. Yet, though the snake hissed its fury, mouth wide and venom dripping from its fangs, it did not strike.

The bald man gave a toss of his hand, sending the snake fluttering into the air. Arvin raced across the room, hoping to catch it, but the snake was too quick. It flew out the window. Arvin turned to glare at the human, teeth bared.

The bald man held up an admonishing finger. “Control,” he said.

Now Arvin understood. The bald man was yet another tutor, come to drill him in moderation and self-restraint. A human tutor, this time, to further humiliate him. “The flying snake held its temper,” Arvin hissed back at the man. “So what?”

The bald man chuckled. “You misunderstood my demonstration,” he said. “I held the snake’s temper. With mind magic. But before I could do that, I had to learn to control my own.” He stared for several long moments at Arvin without speaking then asked, “Is this something you would like to learn?”

“Yes,” Arvin hissed, speaking aloud in his sleep. “I want to learn.”

Suddenly the dream became more chaotic. He was no longer a yuan-ti child, but himself-Arvin-an adult human. Yet strangely, his skin was covered in serpent scales. They were as brown as the bald man’s skin had been, and crisscrossed with bands of reddish brown. No, that wasn’t a scale pattern on his arms but a series of red thongs, looped around his body and slowly tightening. Zelia, dressed in a gray robe and skullcap, like the ones the priests at the orphanage had worn, was holding one end of the cord and slowly pulling it toward herself, coiling the cord around one wrist as she hauled it in. She stood on the ball of one foot, her other leg twisted up against her chest, the ankle tucked behind her neck. “Control,” she said, the word somehow coming out as a hiss. Her jaws opened wide. Hot, stinging venom dripped onto Arvin’s temple as she leaned over him, mouth opened, fangs bared-
