Chapter 10: The River

The attack came on the eleventh day, at the river crossing.

The river had no name on Nigel's map — it was marked only as a blue line with a ford symbol, indicating a crossing point where the water was shallow enough to wade. But the river that Nigel's map depicted and the river that they encountered were not the same river. Recent rains in the highlands — the kind of sustained, heavy rainfall that the western lowlands rarely experienced but that the mountains produced with regularity in early autumn — had swollen the water from a wadeable stream into a broad, fast-moving current that was chest-deep at the ford and considerably deeper anywhere else.

"We can't cross here," Nigel said, standing at the water's edge and watching a broken tree branch travel downstream at a speed that suggested the current would treat a human body with similar indifference. "The current is too strong. If one of us goes down mid-crossing, the others can't help without going down themselves."

"Is there another crossing?" Sumi asked.

Nigel consulted the map. "Two kilometres upstream, there's a bridge. Stone construction, marked as permanent. It'll add half a day to our route, but—"

"Half a day we can afford," Sumi said. "Let's go."

They turned upstream. The riverbank was muddy — the kind of soft, saturated ground that received footsteps with a sucking reluctance and released them with a squelch that was audible from twenty metres — and the going was slow, each step requiring deliberate effort to extract the trailing foot from the mud's grip. Ranger walked on the bank's higher ground, where the soil was drier, and Kaito envied the shadow hound's superior navigational instincts.

The bridge, when they reached it, was exactly what Nigel's map had promised: a stone arch spanning the river at a point where the banks rose steeply on both sides, creating a narrow gorge that channelled the swollen water into a thundering rush beneath the bridge's single span. The bridge itself was solid — built in the old style, with massive stone blocks fitted without mortar, held in place by their own weight and the geometric precision of their arrangement.

Kaito stepped onto the bridge first. The stone was wet — spray from the torrent below coated every surface — and his boots slipped on the first step before he adjusted his gait to the shorter, more deliberate stride that wet stone demanded. The bridge was five metres wide and forty metres long, with low stone parapets on each side that rose to waist height and that were, Kaito noted with the tactical awareness that the road had developed in him, insufficient to provide cover if someone shot at them from the banks.

He was halfway across when Ranger snarled.

Not the low-grade warning of detected shadow energy. Not the full-throated combat snarl of the bandit ravine. This was something else — a sound that Kaito had never heard from Ranger before, a sound that was closer to a scream than a growl, the specific vocal expression of a shadow creature that had detected something that terrified it.

"DOWN!" Sumi shouted.

Kaito dropped flat on the wet stone, and the dark flame passed over him.

It was not like the dark flame Chirag had used on the cliff trail — the twin streams of crimson shadow energy projected from both hands. This was a single, concentrated bolt — a lance of dark flame that was narrower, faster, and more intensely coloured, almost black, with edges that flickered between crimson and violet. It struck the bridge parapet two metres behind Kaito's prone body and the stone exploded.

Not cracked. Not chipped. Exploded — fragments of ancient masonry bursting outward in a spray of dust and shrapnel that peppered Kaito's back and legs through his casting vest. A section of the parapet, nearly a metre wide, was simply gone, leaving a gap through which the swollen river was visible forty metres below.

Chirag stood at the far end of the bridge.

He looked different from their last encounter. His cloak was gone — lost or discarded — and his casting vest was torn, the left sleeve missing entirely, revealing an arm that was covered in a pattern of dark lines that Kaito initially mistook for tattoos before realising, with a lurch of his stomach, that they were shadow burns. The physical manifestation of dark flame's corruption of the caster bond — lines of damaged tissue that followed the paths of the caster's shadow energy channels, marking the body the way rivers mark a landscape, through erosion.

His left arm, the one with the shadow burns, hung at an angle that suggested the shoulder injury from Natasha's shuriken had not fully healed. But his right arm was raised, and in his right hand, the amber-red caster beam blazed, and at his side, a new luprinon crouched — different from the first, larger, with eyes that were not merely predatory but frenzied, the instability of a shadow creature whose caster's bond with the Shadow Realm had degraded further since their last encounter.

"I told you," Chirag said, his voice carrying above the roar of the river below, "that I would get what I want. You had the opportunity to surrender the canister peacefully. You chose differently. Now I choose differently too."

He raised his right hand and fired a second bolt of dark flame.

The bolt was aimed at the bridge surface between Kaito and his companions — a deliberate targeting choice designed to separate him from Sumi and Nigel, to force them apart and deal with the isolated threat of the canister carrier. The stone cracked under the impact, a fracture line running across the bridge's width, and for a terrible moment Kaito felt the structure shudder beneath him, the ancient masonry absorbing the force of an attack it had never been designed to withstand.

The bridge held. But the crack was visible — a line of disturbed stone that ran from parapet to parapet, and the masonry on the downstream side was beginning to shift, the blocks loosening as the fracture weakened the arch's structural integrity.

"The bridge won't take many more hits," Nigel shouted from behind the crack. He and Sumi were on the near side, Kaito was on the far side — closer to Chirag, alone, with the canister on his back.

Kaito's caster beam was already active. The wet stone of the bridge provided poor shadow conditions — the spray from the river below diffused the light, creating soft-edged shadows that would produce weaker, less defined shadow creatures — but it was enough. He cast his shreakle, sending the shadow bird screaming toward Chirag in a diversionary attack that was not intended to inflict damage but to force Chirag to defend, to buy seconds while Kaito assessed the situation and formed a plan.

Chirag swatted the shreakle aside with a backhand of dark flame — the shadow bird dissolving on contact, its form unravelling like smoke in wind — and fired a third bolt at Kaito. Kaito rolled to the left, the bolt striking the parapet where he'd been a half-second earlier, and another section of stone disintegrated.

"You can't beat me," Chirag said, advancing along the bridge. His luprinon advanced with him, the shadow wolf's body low, its eyes locked on Kaito with the unwavering focus of a creature that had identified its target and was waiting for the command to kill. "Your friends can't reach you in time. Your shadow creatures are weak in this light. And the bridge is going to collapse in approximately three more shots, which will put you in a river that will kill you as efficiently as my dark flame. Give me the canister."

Kaito was on his feet now, backed against the remaining section of parapet on the upstream side, his caster beam blazing in his left hand while his right hand formed shadow symbols with the speed that was his greatest gift and that was, in this moment, the only thing standing between him and the specific category of death that involved either dark flame or drowning.

He cast his komodon — the muscular reptilian shadow that materialised between him and Chirag, its armoured plates absorbing the first dark flame bolt that Chirag directed at it. The komodon roared — a sound that shook the bridge and added its vibration to the river's roar — and charged Chirag, who sidestepped with the fluid grace of a fighter who had been dodging shadow creatures for years and who regarded a komodon's charge as a predictable inconvenience rather than a genuine threat.

But the charge was not the attack. The charge was the distraction.

While Chirag dodged the komodon, Kaito cast a second creature — not from his standard repertoire but from a symbol he had been practising in secret, a symbol he had found not in the official guidebook but in the margins of a text that Nigel had shown him months ago, a creature that the documentation classified as "theoretical" because no living caster had successfully summoned one since the Purge.

A shadow serpent. Not the small, documented vipers that were standard low-level casts. A constrictor — massive, four metres long, its shadow-form body as thick as Kaito's torso, materialising not on the bridge surface but on the bridge's underside, in the deep shadow beneath the arch where the spray and the darkness created conditions that were, for this particular creature, ideal.

The serpent rose from beneath the bridge like something emerging from a nightmare.

It came up through the gap in the destroyed parapet — the gap that Chirag's own dark flame had created — and it struck with the speed that constrictors possess in reality and that shadow constrictors possessed in amplified, terrifying abundance. Its coils wrapped around the luprinon before Chirag could react, constricting with a force that compressed the shadow wolf's form until the creature howled and began to dissolve.

Chirag's eyes widened. Not with fear — with recognition. He knew what a shadow constrictor was. He knew that the symbol had been lost during the Purge. And he knew, in that moment, that the junior officer he had dismissed as an easy target was something else entirely.

"Where did you learn that?" he demanded, his composure cracking for the first time.

Kaito did not answer, because he was too busy maintaining the constrictor — which required more energy than any shadow he had ever cast, the drain on his caster beam and his shadow bond pulling at his concentration like weights tied to his thoughts — and because the answer would not have helped Chirag and Kaito was not in the habit of helping people who were trying to kill him.

From behind the crack, Sumi acted.

She had not been idle during Kaito's battle. She had been waiting — calculating, positioning, communicating with Ranger through the bond — and now she sent Ranger across the crack in the bridge with a running leap that carried the shadow hound over the damaged section and onto Chirag's side of the span. Simultaneously, she cast her komodon to reinforce Kaito's position, and Nigel cast his barrier — the advanced technique Natasha had taught him — creating a containment field around Chirag that closed from three sides while the bridge's parapet sealed the fourth.

Chirag was trapped. His luprinon was dissolving in the constrictor's grip. His dark flame could break the barrier, but the time required to charge a shot powerful enough would give Ranger — who was already airborne, teeth bared, shadow-form eyes blazing — the opening to strike.

For a long moment, the combatants held their positions. The river roared below. The bridge trembled. And Chirag — scarred, burned, his corrupted caster bond visible in the shadow burns on his arm and the instability of his remaining shadow energy — looked at the three junior officers and the four shadow creatures arrayed against him and made a calculation.

He chose retreat.

His dark flame erupted — not at the officers or their shadows but at the bridge surface beneath his own feet, blasting a hole in the ancient stone that opened onto the river below. Before anyone could react, he dropped through the hole, and the river swallowed him.

Kaito lunged for the gap, looking down into the churning water, and saw nothing. The current was too fast, the water too dark with highland sediment, and Chirag — if he survived the fall — was already being carried downstream at a speed that made pursuit impossible.

"Is he dead?" Nigel asked, arriving at the gap and peering down beside Kaito.

"I don't know." Sumi stood behind them, her face taut with the effort of maintaining her komodon and processing the tactical situation simultaneously. "The fall is fifteen metres into fast water. Survivable for a strong swimmer. And Chirag is... resilient."

"He'll be back," Kaito said.

"Maybe. But not today. Today, we cross this bridge and we get to Torcia."

They crossed. The bridge held — barely, the crack widening with each step, the downstream parapet continuing to shift — but it held long enough for three junior officers and a shadow hound to reach the far bank, after which they did not look back, because looking back at things that might collapse was a waste of attention that was better directed forward.

Kaito dismissed his shadow constrictor. The effort of maintaining it had left him drained — his caster beam dim, his hands trembling, his vision slightly blurred with the particular fatigue that accompanied overextension of the shadow bond. But the constrictor had worked. The theoretical creature that no living caster had summoned since the Purge had materialised, fought, and held.

"That serpent," Nigel said, as they walked. His voice was the voice of a person who had witnessed something that conflicted with his understanding of documented reality and who was in the process of updating his understanding. "That was a shadow constrictor. Class Four corporeal. The symbol was lost during the Purge. How did you—"

"I found it," Kaito said. "In the margins of a text you showed me. The symbol was sketched as a diagram, not described in words. I practised it. I didn't know if it would work."

"You practised an undocumented shadow symbol — a Purge-era symbol — without knowing if it would produce a creature or blow up in your face?"

"I had a reasonable hypothesis."

"You had a hunch."

"Same thing."

Nigel opened his mouth, closed it, opened it again, and then shook his head with the expression of a person who has decided that further argument is pointless because his interlocutor is both right and insane and the combination does not yield to logic.

Sumi said nothing. But she was smiling — the small, private smile that she reserved for moments when Kaito did something that was simultaneously brilliant and reckless and that she would never admit she admired because admitting it would encourage him to do it again, which he would do anyway, because Kaito did not require encouragement to be reckless. He required only an opportunity.

They walked toward Torcia. Two more days. The canister was safe. The bridge behind them was crumbling. And somewhere downstream, a scarred man was either drowning or swimming, and the answer mattered less than the fact that the road ahead was clear and the mission was almost complete.
