a soap bubble, but gave before her, sliding wetly over her fingers.
Any refuge was better than none. Tiaan pushed into the clinging stuff, its resistance broke and she was through. It was even colder here, and so dark that she could see nothing but the shimmering edges of a second bubble, a cube with curved faces that contained within it another, smaller cube, and inside that another, and another, and another. The hair stirred on her head. Infinity blocked her way – infinity and nothingness. This was a forbidden place.
She spun around but behind her now felt like rock, even when she touched her hedron. Tiaan moved toward the cubic bubble. Its walls began to wobble, and so did the inner cubes, vibrating faster and faster until she could no longer see them.
Shifting Haani on her shoulder, Tiaan lowered her head and pushed at the bubble. The wall parted but inside was like the previous one, though smaller. Her head touched the upper face of the cube, which was freezing. The nested cubes extended to an infinity that frightened her.
Since there was no way back, Tiaan pushed through the wall of the next cube. The first breath burned her lungs. With the next, she felt frost forming in her nostrils. She tried to back out but the wall resisted her. Panicking, she kicked the face of the cube in front of her. It was much more solid – more like flexible glass than bubble – and her sandal bounced off.
Steadying Haani, Tiaan lifted the hedron over her head. At once she saw the coloured energy patterns of the field swirling around her like a psychedelic tornado. She drew power into the hedron and reached out. As her fingers touched the wall, it thinned, so she scored the crystal across and back. The bubble vanished with a faint tinkle and a blast of freezing air. One by one, the other cubes popped until the tunnel lay open before her. Unfortunately it was also open behind. The illusory barrier had disappeared.
Some distance along, she emerged in an open cavern of rough-hewn stone shaped like a cone standing on its base. It was strikingly different from the rest of Tirthrax, where the stone had been carefully polished and intricately decorated. The rock here looked deliberately unfinished.
The cavern was dimly lit by something circular, high on one wall. Her eyes adjusted. It was a shaft that ran up through the mountain at a steep angle. Icicles hung from its lower lip and the light was daylight, deep blue as if filtered through ice. It must be morning outside.
Moving on, she passed through a blue corona like illuminated mist, though more solid. She distinctly felt its resistance. It was one of a series of concentric coloured rings lit by the light from the upper shaft. Each ring was a deeper hue than the one surrounding it. A circle of indigo, almost black, filled the centre. Tiaan pushed through the rings and almost fell into another shaft, a continuation of the first.
Laying Haani beside it, she peered down. The shaft was a smooth bore through the rock, its sides as polished as glass. She could not tell how far it went, though wisps of dark mist coiled lazily around the walls, and in the depths it had the look of a frozen whirlpool. She wondered what it would look like if it unfroze. Taking up a chip fallen from the ceiling, she dropped it in. It clicked off the sides a couple of times, she heard nothing for thirty or forty heartbeats, and at last a frosty tinkle. The shaft was deep. It would do.
The sounds came echoing back in reverse order: the tinkle, and a long time later the clicks, greatly magnified. The last click thundered out, whirling the coloured rings about, and silence fell once more.
The child looked to be sleeping but her little chest was sunken, the broken ribs driven into her lungs by the blow from the javelard. A smear of blood tinged her lower lip. Tiaan wiped it off, smoothing the pale hair with her fingers.
Taking Haani in her arms, she sat beside the shaft, rocking. A tear trickled down one cheek. Little Haani had been the happiest of children, living a carefree life with her mother and aunts by the lake, until Tiaan came. Until the nylatl – a creature of mad savagery – gorged itself on Haani’s mother and aunts. The awful memories went round and round.
