There was a deafening crack and a flash of cold blue light, as the fire fury bound within the coldstone greedily sucked the warmth from the world around it.
Coldstones were expensive works of crafting, containing fire furies far more powerful than those found in furylamps or those used to manage the heat of a kitchen's stove and oven. They were specially bound, and though created to draw in all the heat they possibly could, the bindings placed upon them prevented them from pulling more than a tiny trickle into themselves at any one time. The result was a stone that leeched the heat from everything around it over the course of three or four months-the limit of the stone's construction. Placed in an insulated storage box, a coldstone could keep food placed inside it well chilled, even preserve ice over the course of a hot summer.
But in shattering the stone to which the fire fury was bound, Kitai had loosed it to sate its hunger for warmth in a single, unbelievably frigid instant.
The blue fire of the loosed fury's hunger lashed out through the water in a wave of chilly light. Rill and Isana prevented the cold from rushing back up the stream, and instead it followed the course of least resistance, leaping through the arch of water, freezing it to solid in an instant. The wave of frozen blue fire crashed down onto the surface of the Tower and spread out through it in a glittering haze, freezing the water there into a rough-surfaced sheet of ice.
Kitai let out a whoop of excitement and raised a triumphant fist. Isana, shaking with weariness, released the aqueduct's current, which immediately resumed its course in a surge that gradually began to sink back to its original levels. Her foot slipped, and she almost fell, but Rill swirled around her before she could, supporting Isana and helping her regain her balance. For a moment, the fury appeared in the only physical form Isana had seen it take, the shape of a face-a mirror of Isana's own features, when she'd first bonded with Rill as a gawky, thirteen-year-old girl-that appeared on the surface of the stream, smiled, then vanished once more.
Isana stepped wearily out of the water, her skirts soaked from her near fall, and stood beside Kitai. "Now what?" she asked. Her voice sounded rough, even to her own ears.
Kitai gave her a pensive glance, returned her attention to the building, then down to the grounds below, her gaze roaming warily. She reached into her case of coiled lines again and began taking them out. "We wait here. Once they come out on the roof, I'll throw them the lines, and they'll swing over, just as I did with you. Then we meet Ehren."
"What if…" Isana shook her head. "What if they're caught?"
Kitai frowned, her hands moving swiftly and steadily, preparing the lines, her eyes everywhere. "They are not caught yet."
"How can you know that?"
She touched one hand briefly to her chest. "I feel him. Excitement. Fear. Determination. Had he been captured, he would immediately begin blaming himself for failure."
Isana blinked at Kitai. "You know him well, don't you?" she murmured. Then Isana gave the younger woman a thoughtful and rather whimsical smile. "This must be what it feels like when I tell others without watercraft what it is like to sense other people's emotions."
"It doesn't feel the same at all," Kitai said absently. "With him, it is more nebulous, but… deeper, somehow. The emotions of others are flat, like a painting, perhaps. His are more rounded, like a sculpture."
Isana frowned over her words for a moment, then caught a sudden flash of emotion from Kitai-realization and chagrin. She turned to stare at the Marat woman. "Kitai," she said. "How could you possibly know that?"
Kitai stared at her, frozen for a heartbeat, her green eyes wide. Then she turned back to her tasks, biting her lower lip.
Isana stared at her in dawning comprehension. "How could you know the difference unless you'd felt it yourself," she murmured. "Watercraft. Kitai…"
"Quiet," Kitai said, her voice flat with worry, and nodded to the arched column of ice stretching to the Tower. "Someone will see that soon. Don't make it easy for them to find us and shoot us."
Isana would have been choked silent by the implications in any case. No Marat had ever used furycraft. No Marat could. And yet if Kitai truly had knowledge of watercrafting, it meant that she, alone of her people, could wield power through Aleran furies.
Kitai was the only Marat ever to form a bond with an Aleran, and that bonding, Isana knew, somehow shared portions of each being in it with the other. Walker, the gargant bonded to Doroga, Kitai's father, was uncommonly intelligent for a simple beast, and seemed to understand Doroga implicitly. Doroga himself was taller and more heavily laden with muscle than the Marat from the other clans, and Isana knew him to be almost unbelievably strong.
If his daughter had bonded with Tavi in a similar way, then her furycraft could only be the result of that bond.
Had Tavi found the strength inherent in his father's blood at last?
Isana's heart leapt, at once terrified and exultant. In her fear, she had attempted to hide his identity, and in so doing she had stunted the development of his furycraft. She had believed the damage permanent.
Had it been healed? Had her son been given a second chance, despite her errors? Might he have gained the strength that could protect him from the forces that would almost certainly attempt to destroy him once his identity was known?
For years she had despaired of Tavi's fate should his identity ever be learned, and her helplessness to protect him in the face of the vast powers of those such as Lady Aquitaine had been a constant, bitter taste in her mouth.
Now something strange and almost forgotten blossomed to life in her heart, flickering and small but bright against the darkness of her fear.
Hope.
"Kitai," Isana hissed. "Has my son come into his furies?"
Kitai turned to stare hard at Isana.
Before she could say anything, ice snapped and cracked with a sharp detonation, and the doors on the roof of the tower slammed open.
Araris came through them first, looking sharply around him, and even in the dimness, Isana could see the sudden gleam of his teeth as he smiled at the ice coating the roof. His gaze tracked the graceful arch of the column of ice back to the aqueduct, and he flashed his hand in a quick wave at them before turning back to the stairs behind him, beckoning.
Tavi emerged from the Tower, and hard on his heels was a monstrous figure straight out of a nightmare. The Cane, Ambassador Varg, she assumed, towered over even Tavi by at least a full yard, and its black-furred form was both lean and powerful-looking. The Cane emerged into the open air and paused for a moment, then threw his head back, lifted his muzzle to the sky, and spread wide his clawed arms. Then he shook himself, looking for all the world like a dog throwing water from his coat, and dropped into a relaxed crouch, following Tavi as the young man moved with wobbling haste over the ice to the edge of the roof.
Without a word, Kitai whirled the first of her lines and sent it zipping across the empty air to Araris. He caught the rope, and as Kitai played out slack, he sheathed his sword and set his foot in the loop of rope, just as Isana had done. Then he swung out into the open air, swung back and forth once, and began to spin gently as Kitai hauled him upward.
Isana glanced sharply at the young woman. Kitai had no more difficulty hauling up Araris, complete with his armor and weapon, than she had with Isana, and a second later, Isana recognized the slightly absent focus of Kitai's gaze. She had seen her brother's face holding the same expression, often enough, when he labored on the steadholt.
Kitai was using earthcraft to strengthen her.
Once Araris was up, Kitai flung the next line to Tavi. He, too, secured himself and swung out from the roof of the Tower. Araris, Isana noted, anchored the line behind Kitai, his intent face tracking the young mans progress while the anxiety and frustration he felt over being unable to get his charge to safety any faster pressed against Isana like a sheet of scratchy, sweat-soured burlap.
