The dark armor was invisible during the day. Voss willed it dormant and the plates receded beneath his skin, leaving no trace except the faint dark lines on his forearms that appeared when he used Thread Sight. At night, alone in his bunk, he could feel the ancient presence resting — a warm weight in his chest, like a second heartbeat that beat slightly out of sync with his own.
Three days passed before the echo spoke again.
He was in the training arena, carving a dead C-rank forest spider from Squad 4's exercise. The arena was empty — late afternoon, between scheduled sessions. The spider's threads were standard fare. Voss harvested mana threads on autopilot while his mind worked the problem of the island's subterranean infrastructure.
"The threads in that spider are better than what you're taking."
The voice came from inside his skull. Not his thoughts — a distinct presence, a different cadence, the voice of someone who'd been doing this for eight centuries and had opinions about technique.
Voss's hands froze on the spider's carapace. "You're awake."
"I don't sleep. I conserve." The echo's voice was dry. Worn. Like paper that had been read too many times. "You're harvesting the mana threads from the outer nervous system. The better ones are in the spinnerets — the organs that produce the web silk. Those threads encode the spider's sensory network. They'll improve your Sight more than the standard mana threads."
Voss looked. The echo was right. The spinneret organs contained silver threads with a finer weave than the ones he'd been taking — higher resolution, if that word applied to mana structures. He'd been ignoring them because the spinnerets weren't part of the standard carving protocol. No material value.
He adjusted his grip. Cut into the spinneret cluster. The threads inside were precisely as the echo described — tighter, more complex, shimmering with a quality that his standard mana threads lacked.
He absorbed two. His Thread Sight range jumped by three meters. The clarity sharpened. He could see individual thread filaments from thirty meters now, where before they'd blurred into a mass at that distance.
"You know the anatomy," Voss said.
"I know all the anatomy. Eight hundred years ago, I carved everything. Every species. Every rank. I had Thread Sight longer than you've been alive, and I used it on things that don't exist in your era." The echo paused. "The spiders are smaller now. In my time, the C-rank variants were the size of carriages."
"How much do you remember?"
"Everything I experienced. Nothing I heard secondhand. The crystal preserved my direct memories. Conversations, reports, secondhand intelligence — those degraded. But what I saw with my own Sight, what I touched with my own hands, what I cut open and read — that's all here."
Voss finished the spider and sat back on his heels. The arena was still empty. The echo's voice was internal — no one else could hear it. But speaking aloud to an empty room would draw attention he didn't need.
He shifted to thought-communication. The echo could read his directed thoughts the same way it projected its own.
*The Sealed Domain. Tell me about it.*
"Not yet. You're not ready for that."
*I'll be inside it in fifty-eight days.*
"And in fifty-eight days, I'll tell you what you need to know. Not before. The information is too large for a mind that hasn't been prepared."
*Prepared how?*
"By absorbing more threads. By expanding your Sight's capacity. By building the neural architecture that can process what I'm going to show you." The echo's voice shifted — less dry, more deliberate. Teaching mode. "Your Thread Sight is a muscle. You've been using it like a hand tool — grab threads, pull, integrate. But it's capable of much more. It can read structures. Map systems. Analyze living mana networks. And with enough development, it can do something I never fully mastered."
*What?*
"Cut living threads."
Voss went still. Thread Sight worked on the dead. That was the fundamental rule. He could see threads in corpses, absorb them, read them. But living creatures' threads were invisible to him — locked behind the active mana field of a functioning body, shielded from external perception.
"I said I never fully mastered it," the echo continued. "But I got close. In the last days of the war, I could see the threads of living demons — faintly, like shapes behind frosted glass. I could reach in and cut. Not cleanly. Not reliably. But enough to disrupt their abilities, weaken their structures, unravel them from the inside."
*Thread Severance.*
"A name I never gave it. But accurate." The echo was quiet for a moment. "The Sovereign is a woven entity. Not a creature with a body — a tapestry of threads given consciousness. Thread Sight is the only power that can perceive its structure. And Thread Severance is the only power that can cut it."
*That's why it fears Thread Sight.*
"That's why it's spent eight hundred years hunting Carvers who develop the ability. I was the first. I nearly killed it. It will not allow a second chance."
*Then why am I still alive?*
"Because it didn't find you in time. The detection protocols it built into its demons — the standing orders to report anomalous behavior around corpses — those were designed to catch Thread Sight early. Before the user became dangerous. You developed faster than its network could track."
Voss absorbed this. The timeline checked out. His Thread Sight had gone from zero to operational in weeks, powered by the feedback loop of mana threads improving the Sight that harvested more mana threads. The convergence-zone demons had seen him in the killzone, but by the time their reports filtered through the command hierarchy to the Sovereign, Voss was already inside the Divine Legion's protection.
*The Demon King in the capital knew about me. Had detailed intelligence.*
"Not from its own network. From human sources. The Sovereign has seeds — fragments of itself — embedded in human hosts. They act as intelligence assets, reporting through channels that Thread Sight can't detect because the hosts are alive."
*The mole.*
"Not a mole. A seed. A piece of the Sovereign's consciousness lodged in a human brain, influencing thought, directing action, reporting intelligence. The host may not even know they're compromised."
Voss felt the implications spread through his mind like frost through Mira's nervous system. A demon seed. Not a traitor by choice but a victim of parasitic intelligence — someone whose thoughts were not entirely their own.
*How do I find them?*
"You can't. Not yet. The seed is in a living host. Thread Sight can't see living threads."
*Thread Severance.*
"When you develop it. If you develop it. Seeing living threads is the first step. Identifying a demon seed within those threads is the second. Both require a level of Sight development that you're months from achieving."
*Months I may not have.*
"Months you will use wisely." The echo's voice had a weight to it now — the authority of a teacher who had made every mistake his student was about to make and paid for them in blood. "Train your Sight. Absorb everything you can from the island's population — the variety here is better than anything you'll find on the mainland. Push your range. Push your clarity. Push until you can see the structure of this island's mana network the way you see the threads in a dead wolf."
*And then?*
"Then I'll show you what the Sealed Domain really is. And you'll understand why everything you've been taught about it is wrong."
The echo went quiet. Conserving. The warm weight in Voss's chest settled back to its resting pulse.
---
Voss trained.
For the next four weeks, he pushed his Thread Sight harder than he'd pushed anything in his life. Every training exercise became a harvest — C-rank monsters on the island's surface, each one offering threads of a quality and variety that mainland barriers couldn't match. The island's elevated mana density made everything brighter, denser, more potent.
He absorbed mana threads from crystal moths that lived in the island's cave mouths. Defense threads from armored bears that ranged the northern forests. Speed threads from cliff-diving hawks with wingspans wider than he was tall.
His Thread Sight range expanded past sixty meters. Seventy. Eighty. The clarity improved until he could identify individual thread types from maximum range — stat, ability, memory, each one distinguishable by color, density, and vibration pattern.
With the dark armor active, his range jumped to over a hundred meters. The entire training compound was visible. Every thread in every body within a hundred-meter sphere, mapped in his perception like a diagram of a living system.
The echo offered guidance. Small corrections. Anatomical pointers. Things like: "The bear's hibernation gland contains a unique defense thread that will insulate your neural pathways against psychic attack. You'll need that in the Domain."
And: "Stop absorbing wolf strength threads. You've saturated that species type. Diversify. The island's spider population has a structural thread that will give you flexibility in your tendons — not strength, not speed, but the ability to move in ways human joints weren't designed for."
And once, quietly: "You remind me of myself. That's not a compliment."
Voss didn't ask what he meant.
He trained with the squad too. The combat drills sharpened Squad 7 into something precise and deadly. Dex's Rage State, controlled and focused. Kael's marksmanship, silent and surgical. Tam's shield work, immovable and absolute. Lena's equations, evolving from suppression to something more offensive — area-of-effect formulas that turned math into fire.
And Ryn. Ryn was everywhere. Adjusting formations. Drilling contingencies. Running casualty scenarios at three AM because she'd woken up from a dream about the squad wipe that had killed everyone she'd led before. She pushed them hard. Pushed herself harder.
Voss found her in the medical supply room at oh-two-hundred on the thirty-first day, inventorying trauma kits.
"You should sleep," he said.
"You should mind your own business."
He sat on a supply crate. The room was small, cluttered with the organized chaos of a combat medic's workspace. Bandages, tourniquets, mana infusion kits, bone-setting splints. The tools of a trade that kept people alive long enough to die from something else.
"The Sealed Domain," he said.
Ryn stopped counting bandages. "What about it?"
"Have you been inside before?"
"No. The trial is by selection. Squad commanders above A-rank with minimum two years of service. This is my first rotation."
"What do you know about it?"
"Eight hundred years old. Size of a small country. Arctic region. Annual trial to weaken the sealed entity inside. The most prestigious operation in the RDC." She set down a trauma kit. "Why?"
He wanted to tell her what the echo had said. That the Sealed Domain was wrong. That the trials were wrong. That everything the institution believed about the Domain was based on a misunderstanding eight hundred years deep.
But the echo had said not yet. Not until Voss was ready. Not until his Sight was strong enough to see what needed to be seen.
"I have a feeling it's not what we've been told," he said.
Ryn looked at him. The scar on her jaw caught the supply room's fluorescent light. Her eyes were hazel and steady and very tired.
"I had a feeling about the last barrier too," she said. "The one that killed my squad. The feeling was right."
She went back to counting bandages. Voss sat on the crate and watched her work and thought about an ancient Carver who'd been the strongest human alive and still lost. Because he fought alone.
Twenty-seven days until the trial.
The echo slept. The armor hummed. And somewhere beneath the island, in the chambers where the dragon bones turned to stone and the Rift energy pulsed like blood through the earth's veins, a heartbeat kept time.
Slow. Patient.
Getting stronger.
