The academy's central hall buzzed with restrained excitement the morning after the River Hunt. Sunlight streamed through tall arched windows, catching on the polished stone floors and the faint spirit runes etched into the walls.
Students from all eight teams stood in neat rows while Instructor Vell read out the final point tallies in her crisp, no-nonsense voice.
"First place: Team Crimson Flame with thirty-eight points."
Garrick and his group cheered loudly, though Garrick's smirk faltered slightly when his eyes flicked toward Kai.
"Second place: Team Mistwalk with thirty-one points."
Kai's team stepped forward to polite applause. Mira allowed herself a small, satisfied smile. Tomas rubbed the back of his neck, still sore from the Riverclaw's blow. Seline simply looked relieved they had survived.
Vell continued, "As promised, the top three teams will receive personal guidance and one full session in the academy's Essence Pool. The rest of you—return to regular training. Remember, points can be lost as easily as gained."
After the assembly, a senior assistant led the six winning students through a narrow corridor beneath the main hall. The air grew cooler and carried a faint metallic tang, like ozone after a storm. They descended a short flight of stairs into a circular underground chamber lit by soft blue spirit lanterns.
In the center of the room lay the Essence Pool—a wide, shallow basin carved from a single block of luminous white stone.
Clear water filled it to the brim, but the liquid shimmered with inner light, swirling slowly as if alive.
Tiny motes of colored energy drifted beneath the surface, remnants of countless spirit cores that had been dissolved here over the years.
"This pool condenses and purifies essence," the senior assistant explained. "Absorb too quickly and it will tear your spirit veins. Absorb too slowly and you waste the opportunity. The Riverclaw core you contributed will be dissolved first for the group, then individual cores. Begin when ready."
Garrick went first, eager to show off. He knelt at the edge, placed his palm on the stone rim, and closed his eyes. Flames flickered faintly around his shoulders as the pool responded. The water rippled violently, drawing in the essence of a Windfang core he had offered. His face twisted in concentration, sweat beading on his forehead. After several minutes he stood, breathing hard but grinning.
"Feels stronger already," he boasted, flexing his fingers where small flames danced more steadily than before.
Mira went next, then Tomas and Seline. Each emerged looking exhausted but visibly improved—stronger foundations, slightly brighter spirit auras.
Kai was last.
He knelt, placing both hands on the cool stone. The Riverclaw core—large, earthy brown, and still humming with residual power—was lowered into the pool by the assistant. The moment it touched the water, the entire basin ignited with muddy light.
Kai drew a slow breath and reached inward.
The shadow answered instantly.
It surged forward like a starved beast, wrapping around the incoming essence before the pool could fully purify it. Pain exploded behind Kai's eyes.
The Riverclaw's stone-heavy energy clashed violently with his shadow affinity. It felt like trying to swallow a boulder made of jagged ice—unyielding, crushing, and bitterly cold.
His body trembled. Dark veins pulsed visibly along his arms for a split second before he forced them back. The shadow devoured the stone essence greedily, breaking it down, twisting it, converting fragments into pure shadow power. But the process was raw and uncontrolled. Every nerve burned.
Zen's earlier warnings echoed in his mind: Control it, or it will control you.
Kai gritted his teeth and pushed. He visualized the Void Step forms, using the slow, flowing movements in his mind to guide the chaotic energy. Gradually, the pain shifted from tearing agony to a deep, aching pressure. The shadow settled, coiling tighter around his spirit core.
A new layer formed.
Not a full spirit ring yet—just the faint outline of his second Essence Vein, thin and dark as midnight smoke, wrapping around the first. Power flooded his limbs. His senses sharpened. He could feel the faint currents of wind from Mira's breathing, the subtle heat radiating from Garrick across the room, the tiny eddies of energy still swirling in the pool.
When he finally opened his eyes, the chamber was silent.
Instructor Vell had entered unnoticed and now watched him with narrowed eyes. "Your absorption took longer than the others. And… there was interference in the pool's flow. Is everything stable?"
Kai stood slowly, hiding the slight unsteadiness in his legs. "Yes, Instructor. Just… a difficult core."
Vell studied him a moment longer, then nodded once. "Very well. Dismissed. All of you—rest today. Tomorrow we begin advanced forms."
As the group filed out, Garrick lingered near the stairs, waiting until the others had gone ahead. He stepped close to Kai, voice low and venomous.
"I saw what happened in the pool. That wasn't normal absorption. Your shadow did something to the essence. If you're hiding some kind of forbidden technique—"
"I earned the same points you did," Kai replied evenly. "We both survived the hunt. Let it go."
Garrick's fists clenched, small flames licking at his knuckles. "This academy has rules. Unusual equals dangerous. If you become a liability, I'll make sure everyone knows exactly what you are."
He shoved past Kai and stormed up the stairs.
Mira waited at the top, arms crossed. "He's getting worse," she muttered as they walked back toward the main courtyard. "And you… you changed again down there. I felt it. Like the air got heavier."
Kai glanced at her. Her Gale affinity made her sensitive to shifts in flow and pressure. Lying would only make her more suspicious.
"I'm still learning to control it," he admitted quietly. "It's not like the other elements. It… wants to take more than I give."
Mira was silent for several steps. Then, unexpectedly, she said, "My mother always told me that different doesn't mean wrong. But in places like this, different people can get you killed. Be careful, Kai."
She left him at the courtyard gate with a small nod—trust still cautious, but no longer absent.
That evening at the old mill, Zen examined Kai thoroughly, pressing fingers against pressure points along his arms and back.
"The second vein is forming well," the old butler said at last, relief evident in his voice. "But the shadow devoured too aggressively. You must practice restraint, young master. Rapid growth draws eyes—both here and beyond."
Kai sat by the window, staring at the river glowing silver under the moonlight. The new power hummed pleasantly beneath his skin, but he could feel the hunger beneath it. The shadow wanted more.
Always more.
"Someone was watching the pool," Kai said suddenly. "Not just Vell. I felt… another presence. Faint, like a shadow that didn't belong to me."
Zen's expression darkened. He moved to the window, gazing out into the night.
"Then the echoes have begun. The River Hunt stirred something. We cannot stay hidden forever."
Kai touched the Voidweave cloth wrapped around his wrist like a bracelet. It pulsed warmly, almost reassuringly.
"Will you tell me more about my parents soon?"
Zen was quiet for a long moment. "When you can carry the weight without it breaking you. Not yet."
Outside, hidden among the trees on the far bank, the lone scout in dark robes crouched motionless. His eyes—glowing faintly with an unnatural violet hue—had observed the entire essence pool session through a thin scrying thread.
He smiled thinly.
"The boy's shadow has awakened its hunger. The rift signature is unmistakable. The masters will want him brought in… or silenced before he grows too strong."
He vanished into the darkness, leaving only a faint ripple in the river mist.
