AETHORIA:The hollow king

"Tell me what a Mirror is," Kael said, at first light.

Sera, who had not appeared to sleep, was sitting cross-legged against the far wall, her hands folded and her eyes open, watching the ward-lines fade as the darkness thinned. She did not look at him.

"What do you know already?"

"Nothing. The word isn't in any text I've read."

"The word isn't in any text the empire permits," she corrected. "There's a difference." She unfolded herself from the wall in one fluid motion and began disassembling the ward-lamps with the efficiency of someone who had done it ten thousand times. "A Mirror is an Aethless — genuinely Aethless, the tests aren't wrong — who can absorb Aeth directly from a bonded practitioner. Not borrow. Not copy. Take. Permanently."

Kael was quiet.

"The one who gives loses the bond," she continued. "Permanently. In the early days of Aethoria, when the kingdoms were still learning what the Aeths were and what bonding meant, there were several recorded cases. They used to call them Thieves in the old kingdom tongue — Aeththieves — but that wasn't accurate. Thieves take what doesn't belong to them. Mirrors —" She paused. "The theory, or what remains of it in texts the empire hasn't burned, is that Mirrors don't take. They receive. There's something in the Aethless condition, some quality of genuine emptiness, that makes them natural vessels. When a bonded practitioner's Aeth comes into contact with a true Mirror, it recognises the void and fills it."

"Against the practitioner's will."

"Not always. In the historical cases — three hundred years ago, the mage called Vael the Unmade — it was said the transfer could be initiated by the Mirror intentionally. Controlled. Used as a weapon or a gift." She packed the last lamp away. "In your case, it was contact under duress. The officer grabbed you. His fire-Aeth sensed the void and moved."

"He didn't choose it."

"No." Something in her voice shifted slightly. Not quite sympathy. Something more careful. "He didn't choose it."

Kael looked at his wrist. The copper lines had settled overnight, no longer raw and furious but steady, pulsing faintly with each heartbeat. "Can I give it back?"

Sera looked at him then, a clean direct look with no particular judgment in it.

"No," she said. "What a Mirror takes, it keeps. The Aeth becomes the Mirror's own. You are now, effectively, a fire-bonded mage. You always were, in potential. You just needed a source."

He absorbed this. Outside the dead tree, the Greywood was doing what ancient forests do in early morning — going about the business of its own strangeness, undisturbed by human events. Birds called in languages that didn't sound quite like birds.

"Why does the empire hunt Mirrors?" he asked.

"Because a Mirror cannot be defeated by magic." Sera shouldered her pack and pressed the bark-seam open. "Every practitioner in Aethoria has a counter. Fire falls to water. Shadow disperses in light. Stone-bonds shatter against wind-Aeth. The military doctrine of every kingdom is built on the principle that power has counters." She stepped out into the pale morning. He followed. "A Mirror doesn't work that way. A Mirror absorbs what is used against it. You cannot use magic against a Mirror without making the Mirror stronger."

"So they're afraid."

"They're rational," she said, which she seemed to mean as a distinction. "The empire built itself on quantifiable power. They can measure a fire-bond. They can train against a shadow-mage. They have procedures, contingencies, counters for everything Aethoria can produce." She moved through the trees with the ease of long practice. "Except this."

Kael followed, watching his footing on the strange Greywood ground — too smooth in some places, too yielding in others, as though the forest maintained its paths deliberately.

"The prophecy," he said. "The Hollow King."

Sera didn't break her pace. "Where did you hear that?"

"The officer, before I — before it happened. He was reading from a list. Aethless of conscription age. He said — he read a flagged name. He said, 'The Hollow King is a death sentence for whoever's near it.'"

"He was reading an empire watch-list," Sera said. "The Solmere Seers issued it four years ago. A child born Aethless in the occupied territories during the year of the third Aeth-surge, seventeen years ago. The seer-text said this child would be the Hollow King — the Aethless One who shatters an empire." She paused. "Solmere has been finding and conscripting Aethless of the right age ever since. Quietly. Efficiently."

"They've been trying to find me."

"They've been trying to find whoever fits the description. Until last night, there were several candidates." She stopped at the edge of a small clearing and looked at him over her shoulder. "Now there is one."

The morning light caught the copper lines on his wrist.

"You knew," he said. "Before. In the square. You were there when it happened."

"I was already watching Durnholt." She resumed walking. "I've been tracking the prophecy candidates for eight months. Following the conscription lists."

"On whose behalf?"

A pause. Not a long one. But present.

"My own," she said.

He didn't believe her.

But the Greywood swallowed the question before he could press it, and somewhere behind them, just at the edge of hearing, something moved through the trees in perfect, purposeful silence — and it was keeping pace.
