The first field practicum of the semester dropped them into a Tier 4 Abyss dungeon forty kilometers south of the Capital.
Instructor Wen Sura briefed the group at the dungeon entrance — a tear in the air the color of bruised fruit, edges flickering with unstable spatial energy. Standard Abyss rift. The kind that appeared every few weeks near major cities, spitting out low-to-mid-tier monsters until a Reaper team cleared the pocket dimension inside.
"Tier 4 dungeon. Estimated monster count: sixty to eighty. Mix of shadow crawlers and flame beetles. Nothing above Level 35." Wen Sura checked her monitoring array — a wrist-mounted device that tracked student vital signs and mana output. "Team of five. Voss leads. Clear the dungeon. Don't die."
"Inspiring," Fen muttered.
The team filed through the rift: Calder, Sable, Fen, Linaya, and Jang Ya. The transition hit like a cold shower — reality bending, light warping, then snapping into the dungeon's interior. A cavern system. Wet stone, bioluminescent moss on the ceiling, and the skittering of too many legs echoing from deep corridors.
Calder assessed. His All Seeing Eye swept the dungeon automatically — three seconds of focus and he had everything. Monster positions, element types, boss location, hidden treasure rooms. He saw it all and showed none of it.
"Standard formation," he said. "Sable, front. Fen, center support. Linaya, rear. Jang Ya, left flank. I'll take right."
"You're putting yourself on the flank?" Jang Ya raised an eyebrow. "The team lead usually takes center command."
"I work better on the edges."
Sable was already moving forward, fire flickering around her fists. Low output — Tier 3, controlled, nothing that would raise flags. But Calder could see the difference the parasite removal had made. Her flames were clean. No dark threads. No instability crackling at the margins. The fire obeyed her completely for the first time in months.
She punched a shadow crawler that lunged from a crevice. The creature disintegrated. Her eyes widened — the barest fraction, the closest Sable Qin came to surprise.
"Stronger than expected," she said.
"Your foundation's solid now," Calder said. "The cap was the parasite, not your talent."
She looked at him. That sharp, amber assessment. Then she turned and kept walking. But her shoulders had straightened, and the fire burned brighter.
The cavern branched into three corridors. Calder pointed. "Left corridor is clear for two hundred meters, then a nest of twenty crawlers. Middle has the flame beetles — about thirty, clustered around a minor mana node. Right is the boss chamber."
Everyone stared.
"How do you know that?" Jang Ya asked.
"Experience. Tier 4 dungeons follow standard spawning patterns. Crawlers prefer branching corridors, beetles cluster around energy sources, bosses take the deepest chamber."
It was true. It was also something he'd confirmed with his Tier 9 identification in the first three seconds. But Jang Ya didn't need to know that.
"Impressive." Her tone said she didn't fully buy it.
They split the work. Left corridor first.
---
The shadow crawlers were exactly where Calder said they'd be. Twenty of them — dog-sized arachnids with carapaces that absorbed light. Their legs clicked on stone as they swarmed.
Sable moved first. A Tier 4 Infernal Storm — wider than her previous best, tighter in its control. The fire swept the corridor. Twelve crawlers died instantly. The remaining eight scattered, climbing walls and ceiling.
Linaya raised one hand. Three skeletal soldiers materialized from shadow — not Ossian, not the dragon, just basic infantry from her standard summoning pool. They moved with sharp efficiency, swords cutting through crawlers that Sable's fire missed.
Fen hung back, healing aura active. The green-gold light of his World Tree core suffused the air around the group — a passive field that boosted recovery, sharpened reflexes, and made everyone feel slightly more alive. He was careful to keep it subtle. The World Tree's full capabilities would raise questions nobody could answer.
Jang Ya used wind lances — Tier 4, surgically precise. She picked off crawlers that tried to flank, each lance hitting a joint or an eye with anatomical accuracy. Good technique. Very good, actually. She fought like someone who'd studied monster physiology the way other people studied history.
Calder contributed Tier 3 fire blasts. Conservative. Adequate. Exactly what a Level 42 fire mage would produce in a controlled exercise.
The corridor cleared in ninety seconds. No injuries. Clean execution.
"Efficient," Jang Ya said, scanning the fallen crawlers. "Your tactical assessment was accurate. All twenty, exactly where you said." She paused. "The flame beetles. Where did you say they were?"
"Middle corridor. Around the mana node."
"And the boss?"
"Deepest chamber. Right corridor."
"You said that before we entered. Before any of us had seen the layout."
"Pattern recognition."
"Pattern recognition," she repeated. The words were flat. She was cataloging the inconsistency, filing it next to the casting speed discrepancy from yesterday's drill. Building a case she hadn't decided what to do with yet.
They moved to the middle corridor. The flame beetles were clustered around a pulsing blue node — a minor mana concentration that the dungeon had formed naturally. The beetles were Tier 3 individually, but their shells reflected fire magic, making them resistant to Sable's primary element.
"Ice," Sable said, stepping back. "Anyone?"
"I've got it," Calder said. He cast a Tier 3 ice spell — Frost Shard, basic and unimpressive. The beetle he hit froze and cracked. He followed with two more. Slow, methodical. The output of someone working at the edge of their ability.
Jang Ya was watching his hands. The way he formed the ice spell. Looking for the compression patterns she'd mentioned in yesterday's drill.
Calder deliberately loosened his casting architecture. Made it sloppy. Added a half-second delay between formation and release that a skilled mage would never leave in. Inefficiency masquerading as limitation.
"Your ice is slow," Jang Ya observed.
"Secondary element. Still developing it."
"You used ice in the Grand Reaping. Round 4. Tier 4 Blizzard, if I remember the footage."
"I pushed past my limit in the exams. Paid for it afterward."
"Did you?"
Fen stepped in before the questioning could continue. "So basically, can we focus on the beetles before they swarm? Because that one's looking at me like I owe it money."
The group refocused. Linaya's skeletons engaged the beetles from the front while Sable switched to physical strikes — gauntlets reinforced with fire mana, crushing shells with raw force instead of spell damage. The beetles fell. The mana node flickered and died with the last one.

The boss chamber was larger than the corridors — a natural cavern with stalactites dripping some fluid that wasn't water. The air smelled sharp, like vinegar and copper. At the center, curled around a Tier 4 spell crystal, was the dungeon boss.
Shadow Mantis. Level 33. Four bladed arms, compound eyes that tracked movement in every direction, and a carapace coated in a mana-absorbing film that neutralized weak spells on contact.
Jang Ya's identification sweep returned the basic data. Calder's All Seeing Eye had already given him everything — weak points, attack patterns, the critical joint at the base of the second-left arm where a well-placed strike would sever the nerve cluster controlling the right side of its body.
"Standard boss engagement," Calder said. "Draw its attention, control its movement, hit the joints."
"Which joints?" Jang Ya asked.
"Any of them." All of them had the nerve cluster weakness, but pointing out the specific one would reveal knowledge he shouldn't have.
Sable didn't wait for the tactical discussion to finish. She charged.
Fire erupted around her — not the careful Tier 3 output from the corridors. This was Tier 4, full power, and it burned with a purity that made the air shimmer. The parasite's absence was obvious now. Her flames had always been strong. Without the corruption dragging them down, they were devastating.
The Shadow Mantis met her charge. Two bladed arms swept down. Sable dodged the first, deflected the second with a fire-reinforced forearm guard, and drove her fist into the joint between the creature's thorax and abdomen. Chitin cracked. The mantis screamed — a high, keening sound that bounced off the cavern walls.
Linaya's skeletons flanked. Jang Ya launched wind lances at the compound eyes. Fen's healing aura pulsed, keeping everyone's stamina topped off.
Calder threw Tier 3 fire blasts at the mantis's legs. Adequate damage. Nothing impressive.
The mantis pivoted. Four arms blurred — faster than a Level 33 boss should move. Calder's All Seeing Eye flagged it immediately: mutation. The dungeon had enhanced this boss beyond its standard parameters. Its speed was Level 40 equivalent.
Sable saw it too late. A bladed arm caught her across the ribs. Not deep — her fire armor absorbed most of the impact — but the force launched her sideways into the cavern wall. Stone cracked behind her.
Fen's healing surged. Green-gold light wrapped around Sable, accelerating tissue repair, dulling pain. She was back on her feet in two seconds, jaw tight, eyes burning.
"Mutant," Calder said. "Speed enhancement. Watch the third arm — it leads."
"How do you—" Jang Ya started.
"Watch it."
The mantis attacked again. Third arm first — exactly as Calder called. Sable was ready this time. She caught the arm with both hands, fire blazing, and wrenched. The chitin joint separated with a wet crack. The mantis lost a limb.
Linaya spoke a word. Her three skeletons dissolved and reformed as a single construct — a skeletal hound the size of a horse, all fangs and speed. It lunged at the mantis's unprotected side and tore through the mana-absorbing carapace.
The boss staggered. Calder hit it with a Tier 4 Flame Blast — his "maximum output." The fire punched through the damaged carapace and cooked the creature's internal organs. It collapsed, twitched twice, and went still.
The spell crystal it had been guarding rolled free. Tier 4 shadow element. Valuable to a shadow mage. Worthless to anyone else.
"Clean kill," Wen Sura's voice crackled through the communication array. She'd been monitoring from outside. "Six minutes, forty-two seconds. Above average for a student group in a mutant-boss encounter. Well done."
Jang Ya collected the crystal. Sable wiped dark blood from her gauntlets. Fen checked everyone's vitals with his healer senses, pronouncing them "aggressively healthy, you're welcome."
Calder looked at the dead mantis and thought about how he could have killed it in three seconds with a single Tier 7 spell and how instead he'd spent six minutes pretending to contribute at a fraction of his capacity.
This was his life now. Abundant power, performed scarcity.

Back at the academy, Calder found a note in his dormitory mailbox. No sender name. No official seal. Just a folded paper with two lines of handwriting he didn't recognize.
*Restricted Archives, Section 9-V. Administrative Building, sub-level 2. Tonight.*
He showed it to Linaya in the training chamber.
"My handwriting," she said.
"You left this?"
"I found something. During my independent study hours in the archives — the librarian lets me access the restricted section because my academic papers on Necromantic theory have faculty sponsorship." She paused. "I was looking for historical precedent on sentient summons. Ossian's case. The Council's records on handling anomalous undead."
"And?"
"I found it. Filed under Protocol 9-V. It's not about undead."
Calder's core pulsed. "What is it about?"
"Void." Linaya's dark eyes were steady. "Protocol 9-V is the Archon Council's complete execution protocol for Void Core users. Step-by-step instructions for identification, containment, and termination. Updated seventeen years ago."
Seventeen years. One year before Calder was born.
"They updated it," he said. "They updated a five-hundred-year-old kill order one year before I was born."
"The protocol includes technical specifications for resonance-detection arrays. Construction timelines. Deployment plans for major population centers." Linaya's voice was quiet. A library whisper that carried the weight of a death sentence. "They've been preparing, Calder. Not for centuries. For decades. Someone on the Council expected another Void Core to appear."
The training chamber was silent. Fen had gone pale. Even the green in his eyes looked dimmer.
"How complete are the plans?" Calder asked.
"Complete enough to build. The resonance arrays target a specific frequency band — 0.7 to 0.9 Hz. Your original Essence generation frequency was 0.8."
"I modified it. Randomized the pattern."
"I know. That's why you're still alive." She pulled a folded document from her sleeve. Thin paper, covered in dense script. "I copied the relevant sections. The frequency specifications, the deployment timeline, the list of cities scheduled for array installation."
"When?"
"The document says Phase One deployment was approved six months ago. Twelve cities. The Capital is first."
Calder took the document. The handwriting was Linaya's — precise, small, every character perfectly formed. She'd copied Council records by hand because taking the originals would trigger the archive's tracking enchantments.
He read the deployment schedule. The Capital's array was sixty percent complete. Installation hidden inside routine infrastructure maintenance. Mana conduits in the streets, sensors in the lampposts, processing nodes in government buildings. The entire city was being wired to detect Void energy.
His frequency modification would scatter the signal. The masking ward would add noise. But neither was designed to defeat a completed, city-wide resonance array running continuous analysis across the entire detection spectrum.
"How long?" Calder asked. "Until the Capital array is operational?"
Linaya's answer was the last thing he wanted to hear.
"Three months."
