The smile faded from Cassie's face in increments, replaced by the particular confusion of someone who had just said something they thought was good news.
"...What's wrong?"
Sunny looked at her outstretched finger, still pointing west, and chose his words carefully.
"Nothing's wrong. It's just that west is the direction we were trying to avoid."
"Oh." She lowered her hand. "Because of the scavengers."
"Yes."
Nephis hadn't moved. She was watching Cassie with an expression that gave nothing away, and Sunny had already learned that her stillness was not the same as inattention. She was processing.
"Tell us about the castle," Nephis said.
The shadow of Cassie's previous excitement returned. She straightened slightly, the way she did when she was organizing something behind her eyes.
"It was a city. Ancient, I think. Huge walls, weathered stone, very old. There were monsters in the streets outside but none inside the castle." She paused. "The castle was on a hill in the center of the city. And it was full of people. Awakened, I'm pretty sure. Some were on the walls. Some were just... living. There was food. There was laughter."
The word landed strangely in the open air of the coral island. Laughter. Sunny could not immediately remember the last time he had heard it.
"Did you see anything else?" Nephis asked.
Cassie nodded, and something about the way she did it was off. Too quickly, with a faint warmth in her expression that she didn't quite suppress. Sunny paid closer attention.
"I saw Sunny leading me through the gates."
The silence that followed was brief and very full.
Sunny kept his face neutral. He was aware, with the precise and uncomfortable awareness that Anvil had spent years cultivating in him, that Nephis had heard exactly what he'd heard. That Cassie's vision had included two people passing through the gates of the castle, and one of them was not Nephis.
He glanced sideways. Nephis was looking at Cassie with the same expression as before. If she had registered the omission, she was choosing not to show it.
Cassie's smile was genuine and uncomplicated. To her, the detail was simply evidence that they would make it. She had no reason to read anything else into it.
Sunny filed the information away and said nothing.
After a moment, Nephis nodded once.
"Then we go west."
They broke camp while the sea was still retreating. There was not much to break: the remains of the fire, the scavenged meat wrapped in broad leaves, the arrangement of their sleeping positions on the seaweed. Within twenty minutes of the decision, they were moving.
Cassie walked between them with her staff forward, its tip reading the ground two steps ahead. In the labyrinth she would need guidance, but on the island's flat surface she moved with a quiet confidence that Sunny had started to find less surprising.
Nephis took point. She moved without wasted motion, her sword undrawn but her hand close to it. Sunny fell to the rear.
The descent from the coral island into the labyrinth was managed via the same gap they'd used the day before. Nephis went first, dropping soundlessly into the mud below. Sunny helped Cassie to the edge, and she descended with careful hands and feet, guided by the sound of Nephis's voice giving brief directional instructions. Then Sunny followed.
The labyrinth swallowed them.
He opened his shadow sense wide, letting it map the narrow passages ahead through every shadow the coral walls cast. The mud was deep after the night's flooding, black and cold, pulling at each step. The coral walls rose high enough on either side to reduce the sky to a pale strip overhead.
For a while, the way was clear.
Then it wasn't.
Scavengers. Seven of them, moving toward them from ahead.
"Stop," he said quietly.
Nephis stopped. Cassie stopped a half-beat behind her, following the sound.
"Seven scavengers on the path ahead. Moving this way, slowly."
Nephis studied the walls on either side of them. "Branching path to the left, twenty meters back."
Sunny nodded. "Yes."
They turned back and took the branch, pressing into a narrower passage that smelled strongly of salt and something older. His shadow sense tracked the scavengers as they passed the junction without turning. Sunny let out a breath.
"Clear."
They resumed. West, or as close to west as the labyrinth allowed, which was never very close. The paths bent and doubled and terminated without warning, and his shadow sense was always reaching into the passages ahead to find the way around.
It was on the third detour that Sunny began to understand the scale of what they were walking into.
The scavengers were not scattered. They were distributed through the labyrinth in numbers that made straightforward movement impossible. Not a horde, not yet, but enough that every route forward collapsed into another detour, and every detour cost distance and daylight he couldn't afford.
He reported what his shadow sense revealed in flat, precise terms. Nephis absorbed it without interrupting, and Cassie kept pace in silence, which was its own kind of discipline.
An hour in, they were crouched behind a coral formation at a dead end, waiting for a cluster of the creatures to finish moving past a junction thirty meters away. His shadow sense registered nine of them, which was more than he'd seen in a single group near the carcass site.
"We're not making progress," Sunny said.
"No," Nephis agreed.
Cassie turned her head toward them. "Should we go back?"
Neither of them answered immediately. Sunny was reading the junction through his shadow sense, tracking the last scavenger as it rounded a curve, thinking about the hours of daylight remaining and the hours required to reach the next viable high ground and whether those two numbers could be made to agree.
They couldn't. Not at this rate.
"It will be worse tomorrow," Nephis said.
"Yes." The scavengers were still feeding. By tomorrow, more would have finished and begun dispersing into the labyrinth. The window wasn't closing, it was already mostly closed. "Going back buys us a night, not a solution."
Cassie's hands tightened slightly on her staff.
Nephis was quiet for a moment. Then: "We fight."
Sunny looked at her.
"Not all of them," she said. "Selectively. Clear the path we need, move fast, clear the next one. We have enough to do it if we don't try to engage every group we find."
Sunny turned it over for weaknesses and found fewer than he expected.
"Cassie stays back until the path is confirmed clear," he said.
Nephis nodded. "Agreed."
"And if my shadow sense can't read deep enough past a group to confirm what's behind them, we go around."
"Agreed."
Cassie said, quietly: "I trust you both."
The three words landed with a weight that Sunny suspected she intended but possibly didn't fully understand. He did not examine them closely.
"Alright," he said. "There are four stragglers moving east on the passage we need. Give them two minutes to clear the junction, then we move."
The first engagement was two scavengers in a narrow passage, and Sunny called it before they rounded the bend.
"Twelve meters. Facing away. One on each side of the path."
Nephis didn't answer. She was already moving, low and fast, her footfalls placed with a precision that left almost no sound in the mud. Sunny followed her lead and positioned himself at the rear, his shadow sense monitoring the junction behind them while she closed the distance ahead.
He felt the moment she struck through the sound of it: a single sharp impact, then nothing. One of them was down.
The second turned.
He'd seen one move before, knew the speed of it, and still he'd placed himself a step too far to the left to intervene cleanly. The creature was already swinging its pincer in a horizontal arc by the time Nephis reset her footing, and she had to drop under it rather than step back, her knees hitting the mud.
Sunny was already moving. He came in from the left while the creature's momentum was still carrying the pincer through its arc, drove his sword into the joint where carapace met the softer tissue beneath the foreleg, and pulled. The blade caught. He wrenched it free and the creature lurched, one leg buckling.
Nephis was back on her feet. She put the sword through the back of the creature's neck with a clean, unhurried stroke, and it went down.
Four seconds, maybe five. His shadow sense swept the junction behind them and found it clear, then reached into the passages ahead. One group sat to the east, distant and unreactive. A solitary creature moved north, heading away.
He let out a breath.
"Clear," he said. "For now."
The hunger nudged at him the moment the fighting stopped. It had been building since they entered the labyrinth, quiet enough to ignore while he was moving but harder to dismiss in stillness. The dead scavenger was Awakened, and its shadow still held the dense quality his Aspect wanted. He left it alone. There wasn't time.
Nephis looked at him. Her knees were dark with mud. She didn't mention it, and he didn't either.
They moved.
The second engagement was worse. Three scavengers held a junction they had to cross, and at least one would have a sightline on them no matter which direction they approached from. Sunny spent two minutes reading the movement pattern through his shadow sense before Nephis ran out of patience.
"They're not going to move," she said.
"I know."
"Then we go."
She went left, drawing two of them, and Sunny went right for the third. His was smaller than the ones before, a straggler with old wounds still healing across its carapace, and he thought that made it predictable. It wasn't. The creature feinted with its left pincer and came with the right, and Sunny read it half a beat too late, twisting to take the blow on his shoulder rather than his chest. The impact drove him back into the coral wall.
The coral wall broke where he hit it, chunks grinding against the Shroud's surface hard enough that he felt the impact through the armor. The noise was enormous in the confined passage.
He pushed off the wall before the creature could follow up. His shoulder was wrong, not dislocated but close, the joint screaming with a specific pain he recognized from training exercises he had hated. He pressed his free hand against a jagged spur of broken coral as he rose and pulled, letting Shadow Consumption draw the sharpness out of it. The spur crumbled under his palm, its point going dull and chalky. He pushed what he'd taken into the Azure Blade, and the sword's point sharpened beneath his grip. He adjusted for the reduced range on his bad side and went back in...
The scavenger was already turning back toward him. He let it come, stepped inside the reach of the pincer rather than away from it, and drove the blade upward through the gap beneath its jaw.
It dropped.
[You have slain an Awakened beast, Carapace Scavenger.]
[Your shadow grows stronger.]
Sunny pressed himself against the intact section of the wall and looked at the damage. A section of coral the size of a door had collapsed into the passage, half of it in chunks and half of it in pale dust. The sound had traveled. There was no question about that.
His shadow sense found two creatures at the next junction to the north. Both had stopped moving, and both faced his direction.
Nephis appeared at his side, blood on her sword hand that wasn't hers. She took in the collapsed wall, then looked at him.
"How bad?"
"Two ahead, but not moving toward us."
She waited.
"Took a hit on my shoulder, but it's still functional."
She studied him for a moment with the same expression she used to evaluate terrain. Then she crossed to him, crouched, and placed her hand on his shoulder without asking.
The white flame ignited beneath her palm. Sunny felt it before he saw it, a warmth that had no right to exist in the cold damp of the labyrinth, spreading through the joint and dissolving the grinding wrongness in it. The relief was immediate.
Nephis's jaw tightened. Her face had gone several shades paler by the time she pulled her hand away, and she took a careful breath before straightening.
"Better?" she said.
Sunny rotated the shoulder. The joint moved cleanly, the screaming sensation gone.
"Yes," he said.
She nodded once and turned away as though she hadn't just done something remarkable. Sunny watched her for a moment, then turned his attention back to the passages ahead.
The hunger had sharpened since the coral spur. Consuming from mundane material barely registered, like swallowing air when what his Aspect wanted was substance. The dead scavenger lay where it had fallen, and Sunny pressed his palm against its carapace before the impulse became a decision. The shadow gave readily. Whatever had made the creature fast and armored flowed into him, and the hunger receded to its usual background murmur, still present but no longer pressing against the edges of his focus. A discolored patch spread beneath his hand, the chitin going pale and brittle where it had been dark and dense.
He pulled away and wiped his palm on his leg.
They pressed against the wall and waited.
Thirty seconds. A minute.
The two creatures at the junction turned away and resumed moving.
Sunny exhaled slowly.
ephis looked at the collapsed coral, then turned away and resumed watching the junction. She didn't say anything about it.
"I know," he said.
They moved.
By midday, they had made real progress. The high ground Nephis had identified from the coral island was visible now, a ridge of darker stone rising above the labyrinth walls to the northwest, close enough that Sunny's shadow sense could almost resolve it.
They were stopped again, this time at the edge of a wide clearing where the coral walls opened into a space large enough to be almost unsettling after hours of narrow passages. The original carcass occupied the center of it, the shark-like body mostly stripped now, its pale bones rising from the mud like a half-submerged ruin. The scavengers moving around it were fewer and less frantic. Most of the feeding was done.
Sunny was reading the clearing through his shadow sense and was about to call a path around the northern edge when something changed.
The scavengers moved. Not the gradual shifting of creatures going about their feeding, but a rapid and unanimous withdrawal, the way animals respond to the arrival of something higher in a hierarchy they understand instinctively and entirely.
Two shapes emerged from the western passage.
Sunny went still.
They were scavengers, technically, but they belonged in a completely different category. Three meters tall, their carapace the color of old blood and black iron, vicious spikes erupting from the joints and the ridges of their backs. Where the ordinary scavengers had heavy pincers, these had bone scythes, long and curved, that swept the mud with each step and cut two shallow furrows in parallel lines wherever they walked.
The regular scavengers scattered ahead of them like debris ahead of a prow.
Sunny watched as the two large creatures walked to the carcass without hurry or interest in the creatures fleeing around them. They didn't feed. They crouched, briefly, and each one extracted something from the remains.
Soul shards. He could see them even at this distance, the cold blue light of them between the creatures' pincers.
They stood, turned, and walked back the way they had come. West. Back into the passage they'd emerged from, carrying the shards without absorbing them, moving with the deliberate purpose of something completing a task it had been given.
The ordinary scavengers crept back into the clearing behind them.
Sunny pulled his awareness back and turned to find Nephis already watching him.
"Two larger variants," he said, keeping his voice low. "Bigger, heavier, bone scythes instead of pincers. They took the soul shards from that carcass and left. Didn't absorb them. They went west."
Nephis was quiet.
"They're collecting for something," Sunny said.
"Yes."
He waited for more. Nothing came.
"They're still in range of my shadow sense. I can track which direction they're heading."
She considered it. "Do it."
He held the two large creatures in his awareness as they moved through the western passages, their shadows growing fainter against his perception as the distance stretched. When they finally slipped beyond his range, he had a direction. West-southwest, and they hadn't deviated once.
Sunny thought about the castle in Cassie's vision, full of people, safety, and laughter.
He thought about what was between here and there.
"We should keep moving," Nephis said.
"Yes," he agreed.
He looked west for a moment longer, in the direction the creatures had gone and his senses couldn't follow. Then he turned and found the path north, toward the ridge.
