Tris struggled to stay conscious. He dropped to his knees, his shielding wavering without Mageslayer's power. He saw the spirits stream from the shattered globe, swirling thickly as heavy fog descended around him. The spirits washed over him, grateful for release, brushing against his mind. By Vahanian's gasp, Tris knew that the spirits were visible beyond his mage sight. Kiara caught her breath sharply as the Orb lost its hold on her and her own shields snapped into place.
From the still-glowing shards of the Orb came a spirit of red flame so bright Tris had to shield his eyes and dampen his mage sight. The Obsidian King rose from the splintered glass. Tris could sense its triumph in release, its anger at being denied its chosen vehicle, its desperation to find a host. He knew that the spirit must have a mage's body to inhabit or die. Tris remembered the vision of the dark sending, of what it would mean should he be taken. He sent all his waning power into his wardings, resolved not to permit that vision to come to pass.
The Obsidian King's power slammed against Tris's shielding. It was a bet, Tris knew, as to which of them was the closest to death. Tris threw all of his power into his shields, resolved to die rather than be possessed. He drew power from the blue glow of his own life thread, though it flickered dangerously; he knew that the Obsidian King was weakening fast. Tris could feel the Obsidian King's panic.
Just when Tris thought that his opponent was at the breaking point, the Obsidian King streaked toward Kiara. Weakened from her ordeal within the Orb, Kiara's shields buckled and dissolved. Tris could hear her soul cry out as the invader forced himself into her mind.
"I... am... back!" a voice rasped from Kiara's body, a mixture of wonder and hideous satisfaction molding her features into a visage not quite her own. Four... five... six... The bells continued their mournful toll, announcing that all had been lost.
Tris staggered as he summoned his power for a final salvo. The struggle with Arontala had drained him badly. Without Mageslayer, the wormroot's poison went unabated. In moments his power would be beyond his control. Blood loss made him lightheaded. He knew that the blue thread of his own life energy was dimming. He looked at Kiara, her face twisted by the spirit that possessed her body, her eyes desperate, and he remembered the torment Alaine and Lemuel endured when their bodies had been seized against their will. The vision of his own possible fate foretold by the dark sending, of a blank-eyed and crippled shell twisted to the will of the Obsidian King, made up his mind. He knew that there was only one way to free Kiara.
You must do what I could not, because you have what I did not.
Bava K'aa's words rang in Tris's mind and he clove toward Kiara, snatching up her fallen spelled dagger. The spell to separate a spirit from the body from the hidden journal of the Obsidian King was clear in his mind. Tris murmured the spell of separation as he hurtled forward, knowing that he could not—must not—think about what he had to do. Tris felt Kiara's soul wrench free from her body and he sheltered it within himself, plaiting her life thread with his own. Weakened as they both were, he could not sustain them both long. Tris listened, heartsick, to the toll of the bells. Seven... eight...nine...
"Forgive me," he whispered as he turned the knife in his hand, and as tears streaked down his face, he sank the blade deep into Kiara's chest.
Dimly, he heard Vahanian cry out and Gabriel gasp. Tris threw all of his remaining power into his shields, holding on to the blade as Kiara's blood soaked his hand and her body sagged against him. It was her scream that pierced the night, as her body convulsed in his arms. The spelled blade, wielded by a mage against both a mage's body and a mage's spirit, struck at the only soul remaining within—the soul of the Obsidian King. In the Plains of Spirit, Tris heard the death scream of the Obsidian King as the dagger rent the soul. Tris felt the ancient life force sunder, saw the dying soul tear free from Kiara's open mouth as her head fell back.
In one last burst of magic, the Obsidian King enveloped them in flames. Tris flung his shields around himself and Kiara, his power and life force strained to the breaking point. An acrid stench rose as the stone floor blackened in a circle around his shields. Gabriel, still shielding Vahanian, cried out as the flare burned his cloak. Then the remnants of the Obsidian King's soul dimmed and went dark, destroyed beyond even the vengeance of the Formless One. Tris sank to his knees, cradling Kiara's body.
Tris sagged forward, too drained to move. Sure he was dying, Tris heard a voice in his mind, close by, as if someone leaned down to his ear. I will sustain you, he heard a man's voice say, and he glimpsed the image of a tall man with golden hair and green eyes like his own. Tris felt no fear; he was too weakened from the fight to argue. He gratefully accepted the stream of life energy that made it possible to move again.
"What have you done?" Vahanian cried. Tris tore at the throat of Kiara's tunic, desperate to find the vial on the strap around her neck.
"What his grandmother could not do," Gabriel said. Tris lifted the vial, his hands slick with Kiara's blood, and carefully pulled free the stopper.
"Please," he whispered to the fates as he lifted Kiara with one arm and tilted back her head, carefully forcing the vial between her lips. "Please."
There was no time for second chances, Tris knew. No time to find Carina. The attack and Kiara's struggle with the Obsidian King had drained both of them. Supporting Kiara's life force with his own was burning his waning energy even faster. Tris could feel that he was pulling heavily from the strange mage's power. Only a few moments were left for Tris to return Kiara's soul. Tris knew he could not last much longer. His side was wet with blood, and he felt a growing coldness that had nothing to do with the night air.
It wasn't at all like he thought dying would be. One part of Tris's consciousness watched from afar, growing sleepy as death drew near, knowing that he had never really expected to survive the confrontation. There was no fear, no pain; only regret, and even that was dulled by the knowledge that with Arontala's destruction, Kait's spirit and the other prisoners were free. I will sustain you, the stranger's voice came again. Tris felt old, strong power bearing him up.
As the final bell tolled midnight, a faint glow began to envelop Kiara's form. It spread from where the potion entered her body, illuminating her. Tris sensed the strong magic of the glow, magic that bore the unmistakable imprint of his grandmother's power. Where the knife had torn into Kiara's chest the skin knit closed without a scar, faster even than the work of an expert healer. Kiara's body jerked as her heart began to beat again. Tris let her spirit slip from within him, gently loosing the glowing thread from his own. As quickly as it came the glow was gone. Tris wavered, nearly losing consciousness.
"That potion... You gambled with Kiara's life?" Vahanian accused.
"No. With his own," Gabriel said. "He couldn't have held on to her much longer."
Tris watched, barely daring to breathe, as Kiara's eyes opened. She raised a hand to touch his face.
Tris could only nod wordlessly, overcome from the physical strain, the fight, the victory, the loss, and the restoration.
"By the Dark Lady, look!" Vahanian gasped, pointing behind Tris.
The doors to the throne room burst open. Two dozen armed men in the livery of the House of Margolan streamed into the room, their weapons drawn.
Tris staggered to his feet, placing himself between the soldiers and Kiara. Not like this, Tris thought. Dear Lady, not so close just to fail. Against the wall, Vahanian reached for his crossbow with his left hand. Tris saw that Gabriel was ready to strike, although the odds were against him.
