The sky paled to silver and rose as [Sarissa] came down to the river. She bent to lave her face, to drink of the cold clean water. When she had had her fill, she knelt there for a while, breathing damp cool air, watching the sun spread light across the horizon.

The river caught the flame of it. She trailed her fingers in water as bright as fire. It was clear here, and filling with light. Fishes darted; weeds swayed in the current. Farther out, where the river was deeper, the water darkened to black beneath the sun’s brilliance.

Sarissa pulled off her boots and waded out into the icy river. The shock of the cold made her gasp, but she steeled herself to bear it. The current tugged at her. She rooted herself in the earth. The water flowed over her but could not move her. When it lapped her chin, she filled her lungs with every scrap of air that they could hold, and slipped into a strange dark-bright world.

She swam as a fish swims, supple and swift, down and down into that realm of dim green shapes and rippling weeds, lit with sudden flashes of light: sun rising, fish leaping. She passed out of the sun’s light, but there was light below her, a gleam in the river’s darkness.

Just as she knew that her breath must fail her, her outstretched hand touched the thing that lay on the river’s bottom. It was hard, colder than the water, and caught fast in a tangle of weeds and clay. She grasped the end of it and thrust against the current. Her lungs had begun to burn. But she would not let go.

The earth fought for the victory, but the water in its current caught Sarissa and swirled her suddenly upward. Blind, half-unconscious, lungs afire, she burst into the light.

She fell on the green bank with her prize caught beneath her. Out of the water it was a massive, icy-cold thing, but its heart was fire.

She lifted herself to her knees. A sword lay in the grass. It gleamed as if it had come new from the forge, grey rippled steel like the water that had begotten it. Its hilt was plain silver without adornment, but for a white stone set in the pommel.

As she knelt in front of it. Tarik flowed out of the river, licking cat-whiskers, flicking a fish’s tail that flowed and stretched and transmuted into a cat’s. He inspected the sword with approval. The water had done well, his glance said, and the sun’s fire, forging a blade for a champion’s hand. If indeed there was a champion in the world, and if, once chosen, he would do what he had been sought out to do.

Tarik, when he was a cat, had a cat’s irony. But it was a fine sword, as solid as earth, and as palpably real. Sarissa trusted that the same would be true of the man for whom it had been wrought.
