Chapter 1: The Army at the Edge of the Forest

There were only footsteps.

Thousands of them — the particular sound that an army makes when it has stopped pretending to be quiet and has begun moving with the confidence of a force that expects to win. The rhythm was not a march, exactly. It was something older than that: the cadence of men who had walked a very long distance and who understood, in their bones and their blistered feet, that the walking was almost over and the fighting was about to begin.

The forest surrounding Sardon was a place that deserved better than this.

In ordinary times — which were, by definition, the times that armies did not traverse it — the forest was remarkable for its density of sound. The pine stands hosted colonies of mynahs that argued from dawn to dusk with the dedicated persistence of birds that believed every territorial dispute was worth having. The fern groves harboured smaller creatures whose movements created a continuous rustling that was, if you listened with attention rather than merely with ears, as complex and layered as a raga: the scurry of a bandicoot in the undergrowth, the deliberate progress of a monitor lizard along a fallen trunk, the cricket chorus that began at dusk and continued through the night with the disciplined endurance of musicians who had been trained by a master who did not tolerate silence.

But on this night, every creature in the forest had stopped.

The mynahs were silent. The bandicoots had retreated into burrows. The crickets had suspended their performance with the instinctive understanding that the audience for tonight's events was not interested in their contribution. The forest had emptied itself of every sound except the footsteps, and the footsteps were enough.

Lord Izanagi stood on the cliffside above the valley and watched his battalion advance.

He was not a man who needed to be present at the front of his forces in order to command them. His generals understood their orders; his captains had drilled the formations; his soldiers had trained for this particular march through this particular forest for the better part of two seasons. But Izanagi had come to the cliff anyway, because there are moments in the execution of a long-planned strategy when the architect wants to see the building rise, and this was his building, and it was rising.

The torchlight below was a river of fire.

From this elevation, the individual soldiers were invisible — swallowed by the darkness of the pine canopy — but their torches painted a line of amber light that wound through the forest like a serpent made of flame. The line was four kilometres long. At its head, the vanguard would be approaching the first of Sardon's outer perimeter wards — the shadow-cast detection barriers that the city's defenders had maintained for three centuries and that Izanagi's infiltrators had been systematically degrading for the past seven months. At its tail, the supply wagons were still emerging from the mountain pass where Izanagi's forces had assembled in secret, hidden from LoSC surveillance by the same geographical features that had hidden rebel shadow casters during the Purge.

The irony was not lost on him. The caves that had sheltered the persecuted now sheltered the persecutor. History, Izanagi had observed, did not repeat itself so much as it reversed itself, and the reversal was always uglier than the original.

He held his calloused hands crossed at the wrists behind his back — a posture he had adopted from his own master, decades ago, and that had become habitual in the way that the physical mannerisms of powerful men tend to persist long after the men who taught them have ceased to exist. His dark hair, grey-flecked at the temples, moved in the mountain wind. His chest was expanded, not from vanity but from the specific physiological response of a man who has been holding his breath for years and has finally exhaled.

This march was the first step. The victory would not be won tonight, or this week, or even this season. But it would be won. Izanagi had the patience that comes from having been patient for a very long time, and the certainty that comes from having eliminated every alternative.

As he surveyed the torchlight, his shadow cast companion — a luprinon, the massive wolf-like creature that had been bound to him since his mastery trials — materialised at his side with the silent precision of a beast that existed partially in the physical world and partially in the Shadow Realm and that regarded the boundary between the two as a suggestion rather than a rule. The luprinon's coat was the colour of deep twilight, shifting between purple and black as the wind ruffled its fur, and its eyes — amber, slitted, ancient — tracked the army below with the calculating attention of a predator evaluating not individual prey but the movement patterns of an entire herd.

"They march well," Izanagi said to the luprinon. He did not expect a verbal response, and he did not receive one. The luprinon communicated through the telepathic bond that all shadow casters shared with their cast companions, and what it communicated now was a calm, predatory readiness — the emotional equivalent of a blade that has been sharpened and is waiting.

Below the cliff, the army continued its advance. The torchlight serpent lengthened as more soldiers emerged from the mountain pass. Somewhere in the forest, a single mynah — braver or stupider than its fellows — issued a tentative call, then fell silent again as if it had remembered, belatedly, that silence was the appropriate response to an invasion.

Izanagi turned from the cliff.

There was work to do. The march on Sardon was the first movement in a composition that would require many more before it reached its conclusion, and Izanagi — who had spent his entire adult life composing this particular piece — intended to conduct every measure himself.

Three hundred kilometres south, in the LoSC Central Sanctuary, a boy named Kaito was trying to cast a shadow dragon.

He had been trying for the better part of an hour, which meant that his caster beam — the focused column of light that every shadow caster used to project their shadow symbols — had been active for long enough that the light-generation crystal at its base was uncomfortably warm against his palm, and the shadows it cast were beginning to wobble at the edges with the distinctive instability that indicated the crystal was approaching its thermal limit.

"You're going to burn out your beam," said Nigel, who was sitting cross-legged on the floor of the Shadowdome with his nose in a book — specifically, his copy of Essentials in Laws and Practices of Shadow Casting, which he had read so many times that the spine was held together by optimism and a strip of cotton bandage. "And when you do, I'm going to say 'I told you so,' and you're going to deserve it."

"I'm not going to burn out my beam," Kaito said, without conviction. He adjusted his hand positions in the light column, trying yet another configuration of finger placements that he had invented on the theory that documented shadow symbols could not possibly represent the complete catalogue of castable creatures. Somewhere in the infinite space of possible hand gestures, Kaito believed, there existed a shadow symbol that would produce a dragon — not the small, lizard-like shadows documented in the guidebook, but a genuine, enormous, flying, fire-breathing dragon of the kind that appeared in the illuminated manuscripts of the pre-Purge era.

The shadow on the dome wall flickered. For a moment, it resembled something with wings. Then it collapsed into an amorphous blob and dissipated.

"That looked like a pigeon," Nigel observed, without looking up from his book.

"It did not look like a pigeon."

"It looked exactly like a pigeon. A pigeon that had been stepped on."

Kaito deactivated his caster beam with the frustrated motion of a young man who had been told, repeatedly and by qualified authorities, that what he was attempting was impossible, and who had not yet accumulated enough failure to agree with them. He was seventeen — old enough to have completed his Dawn Trials, old enough to be weeks away from his Daylight Trials, old enough to have been training under Master Toshio for three years — but young enough that impossibility still registered as a challenge rather than a fact.

"You know what your problem is?" Nigel continued, turning a page. "You want to discover something new before you've mastered what's already known. Master Toshio has told you this. I've told you this. Sumi has told you this. The guidebook tells you this on literally the first page, which I know you haven't read because the first page of your copy is still crisp."

"The first page is a copyright notice."

"The second page, then."

Kaito sat down beside his friend and ran his hands through his hair — dark, perpetually dishevelled hair that resisted all attempts at discipline with the same determination that Kaito himself applied to resisting the established curriculum. He was built lean but strong, with the quick-twitch musculature of a caster who preferred speed and improvisation to the methodical, textbook-perfect technique that Nigel favoured. His eyes — brown, wide-set, permanently carrying the expression of someone who had just had an interesting idea and was about to do something inadvisable with it — surveyed the empty Shadowdome with the restless energy of a person who could not sit still unless unconscious.

"Where's Sumi?" he asked.

"Still practicing her komodon form. She asked us to stay and help her get extra reps, if you recall."

"I recall. I also recall that she's been at it for three hours and she was already better than both of us combined before she started."

"That's not the point. She wants to be perfect."

"She is perfect," Kaito said, then immediately wished he hadn't, because Nigel's eyebrows rose above the frames of his rectangular glasses with the precise, calibrated motion of a person who had been waiting for exactly this kind of slip.

"I'm going to pretend I didn't hear that," Nigel said, "because if Sumi heard you say it, she would kill you, and I don't want to witness a murder the night before our final practice session."

Kaito changed the subject with the desperate agility of a man leaping between rooftops. "We should get her dinner. The fazakai stall on the south terrace closes at ninth bell."

"Now that," said Nigel, closing his book with the satisfied air of a negotiator who had achieved his objective, "is the first intelligent thing you've said all evening."

The fazakai sauce stall was operated by a lonrelmian couple — non-casters, members of the ordinary civilian population that shared the Great Malgarian Plate with the shadow caster community — who had been feeding hungry young casters from this particular terrace for longer than Kaito had been alive. The sauce — a thick, slow-cooked preparation of spices and fermented grain that bore a suspicious resemblance to a particularly aggressive South Indian sambar — was served over steamed rice with a side of pickled root vegetables, and it was, by unanimous consensus of every caster who had ever eaten it, the best food available within the Central Sanctuary walls.

Kaito ordered three portions — two for immediate consumption, one packed in a clay pot for Sumi — and carried them across the lantern-lit terrace while Nigel navigated behind him with his nose already in his plate, eating with one hand and holding his guidebook open with the other, a feat of multitasking that should have been impossible but that Nigel performed with the practised ease of a person for whom eating without reading was as unnatural as reading without eating.

They ate in companionable silence — or rather, Kaito ate in silence while Nigel ate and muttered fragments of shadow casting law to himself, which was his preferred method of revision and which Kaito had long since learned to tune out the way residents of a busy street learn to tune out traffic noise.

The lanterns on the terrace cast long shadows across the stone floor. Kaito watched them idly, his mind drifting to tomorrow's Daylight Trials. The trials were the second of three examination stages that every aspiring LoSC officer had to pass — Dawn, Daylight, and Dusk — and they were, by reputation, the most unpredictable. The Dawn Trials tested knowledge and basic casting ability. The Dusk Trials, which came later, tested advanced combat and field readiness. But the Daylight Trials tested something harder to define: judgment, adaptability, the ability to respond to situations that the examiners designed specifically to be unlike anything the candidates had encountered in training.

Kaito was not worried about the combat portions. His casting was instinctive, fast, and creative — qualities that his examiners had praised and his master had cautioned him about in roughly equal measure, because instinct without discipline was, as Toshio frequently observed, "a loaded crossbow in the hands of a man who has not been taught to aim." Kaito understood the criticism. He simply disagreed with its premise.

What worried him — though he would not have admitted it to Nigel, and certainly not to Sumi — was the knowledge examination. Not because he was unintelligent, but because the specific form of intelligence that examinations tested — the ability to recall documented facts in the correct order and reproduce them on command — was not the form of intelligence that Kaito possessed. His intelligence was lateral, associative, prone to making connections between unrelated things and missing connections between related things, and it had a pronounced tendency to perform badly under the conditions of silence and stillness that examinations required.

"You're thinking about the written test," Nigel said, without looking up.

"How did you know?"

"Because you've stopped eating, and you only stop eating when you're either thinking about something unpleasant or when Sumi walks into the room. Since Sumi isn't here, the logical conclusion is that you're worrying about the test."

Kaito resumed eating. "I'll be fine."

"You will be fine. You studied the material. And if you get stuck, just remember: the examiners are testing whether you understand the principles, not whether you've memorised the exact wording. Write what you know in your own words. Your own words are usually... acceptable."

"Was that a compliment?"

"It was the closest I could get to one without feeling dishonest."

Kaito grinned. Nigel's friendship operated on a currency of gentle insults and quiet loyalty, and Kaito had learned to value both equally. They had been assigned as roommates on their first day at the Central Sanctuary, three years ago — Kaito, the impulsive son of a celebrated senior officer who had died in service before Kaito was old enough to remember him; Nigel, the cautious, bookish son of a lonrelmian family who had no shadow casting heritage and who had arrived at the Sanctuary with the bewildered expression of a person who had been told they possessed magical abilities and had not yet decided whether to be thrilled or terrified.

The friendship that had developed between them was, on the surface, improbable — the reckless caster and the cautious scholar — but it had the structural integrity of a friendship that had been built on the understanding that each person provided what the other lacked, and that the providing was not charity but necessity.

And then there was Sumi.

Katsumi — Sumi to everyone who knew her — had arrived at the Sanctuary a year after Kaito and Nigel, and had immediately complicated Kaito's life in ways that he was still attempting to categorise. She was their age, their training cohort, their fellow student under Master Toshio, and — in terms of raw casting talent — unambiguously the best of the three. Her shadow hound, Ranger, was the most stable and responsive shadow companion in their year. Her technique was precise where Kaito's was improvisational, disciplined where Nigel's was theoretical, and effective where both of theirs sometimes wasn't.

She was also, in Kaito's private and carefully concealed assessment, the most remarkable person he had ever met, a fact that he expressed primarily through the medium of annoying her, which he did with the frequency and dedication of a person who had not yet learned that the opposite of hostility is not the only alternative to indifference.

"Come on," Kaito said, gathering Sumi's packed dinner. "Master Toshio wants to see us tonight. We should get Sumi and head to the instruction room."

They left the terrace, carrying Sumi's fazakai sauce and the weight of tomorrow's trials, and walked through the lantern-lit corridors of the Central Sanctuary toward the Shadowdome where their friend was still practicing, because Sumi did not stop practicing until someone came to get her, and Kaito and Nigel had learned, long ago, that being the ones who came to get her was not a duty but a privilege.
