The following week brought a shift in the rhythm of academy life. Morning theory classes continued as usual—lessons on spirit beast ecology, the history of the five guardian continents, and the fragile balance maintained by the Great Portals. But afternoons now split into specialized training tracks. Kai found himself pulled aside after lunch on the third day.
Instructor Vell waited for him in a small side courtyard reserved for advanced students. The space was enclosed by high stone walls covered in climbing vines, with a smooth training circle of compressed earth in the center. A single ancient oak tree provided dappled shade.
"Kai," Vell said without preamble, "your essence absorption in the pool was… irregular. The Riverclaw core should have strengthened your foundation in stability and defense. Instead, the pool recorded anomalous fluctuations—almost as if the essence was being consumed rather than integrated. I've decided to give you private instruction twice a week. We need to stabilize your affinity before it becomes a danger to yourself or others."
Kai bowed respectfully. "Thank you, Instructor. I'll work hard."
Vell's expression remained stern, but there was a flicker of genuine curiosity in her eyes. "Good. Begin with the basic forms. Show me what you can already do without relying on that shadow of yours."
He moved through the standard academy stances—balanced, efficient, but deliberately ordinary. Vell corrected his foot placement once, then nodded. "Adequate. Now… let the shadow surface. Controlled. No more than a thin veil."
Kai focused.
The darkness rose obediently, cloaking his arms and legs in faint, translucent layers. He demonstrated the Whispering Veil again, his figure blurring slightly at the edges, making it harder to track his exact movements. Vell watched intently, circling him like a hawk.
"Interesting," she murmured. "It devours light and sound rather than simply bending them. This could be useful for reconnaissance or assassination work… but it also leaves traces. Withered grass. Drained air. You must learn to contain the aftereffects."
For the next hour she drilled him on suppression techniques—visualizing a sealed vessel around the shadow, feeding it only measured amounts of external essence. Kai's control improved noticeably, though each successful containment left him drenched in sweat.
As the session ended, Vell handed him a thin manual bound in plain leather. "Forbidden Affinities and Their Management. Read it carefully. And Kai… if the shadow ever feels like it's fighting you for dominance, come to me immediately. Do not wait."
He nodded, tucking the book under his arm. As he left the courtyard, he felt eyes on his back—not Vell's. Someone else had been watching from the upper windows of the main hall.
That night, the real test came.
The academy announced an optional nighttime training exercise for second-year students and promising first-years: "Shadow Drills" in the forested training grounds behind the academy. The goal was to practice stealth and detection under low-light conditions.
Teams would hunt glowing spirit markers hidden among the trees while avoiding "predators" played by senior students.
Kai joined Mira, Tomas, and Seline again. Garrick's group was also participating, though they kept their distance.
The forest at night felt alive. Moonlight filtered through the canopy in silver patches. The air was cool and damp, carrying the scent of pine and river mist. Students spread out, moving silently or in small clusters.
Kai's team moved deeper than most. Using his improved Whispering Veil, he scouted ahead, melting into patches of deeper darkness. He found two markers quickly and signaled the others with a soft whistle.
Then the trap sprung.
A wall of flame erupted across their path—controlled but intense—blocking the way back. Garrick stepped out from behind a tree, flanked by two older students. One was an assistant instructor's favorite, a tall boy with Stone affinity named Renn.
"Looks like the shadow freak wandered too far," Garrick sneered. "Accidents happen during night drills. Maybe you trip into a real spirit beast den. Or maybe your little shadows just… fail you at the wrong moment."
Renn cracked his knuckles, stone energy hardening his fists. "Instructor said to make the drill realistic. Consider this extra training."
Mira's wind swirled defensively. "This is cheating."
"Prove it," Garrick laughed. Flames danced higher.
Kai stepped forward, calm as still water. "You really want to do this here? With instructors nearby?"
"They won't see anything if we're quick," Renn growled.
The three attackers moved at once. Garrick hurled a fireball. Renn charged with enhanced strength. The third boy summoned vines from the earth to bind Kai's legs.
Kai's shadow surged.
He didn't hold back completely this time.
A thin veil of darkness spread from his feet, swallowing the incoming flames mid-air and turning them into harmless smoke. The vines withered and crumbled the instant they touched the shadow layer. Renn's punch met empty air as Kai flickered sideways using Void Step, appearing behind the larger boy and tapping a precise shadow-infused strike to the back of his knee. Renn dropped with a grunt.
Garrick roared and unleashed a continuous stream of fire. Kai raised one hand. The shadow condensed into a small, rotating disc that devoured the flames on contact, growing slightly stronger with every second it fed.
For the first time, real fear flashed across Garrick's face.
"Enough," a new voice cut through the night.
Assistant Instructor Kael—known for his bias toward "reliable" flame and stone users—stepped into the clearing. His expression was cold. "Garrick, Renn—stand down. Kai… you will report to me tomorrow for disciplinary review. Using unstable affinity in a way that endangers fellow students is not tolerated."
Kai lowered his hand, letting the shadow dissipate. "They attacked first."
"Witnesses say otherwise," Kael replied flatly. Clearly, the "witnesses" were already prepared.
Mira opened her mouth to argue, but Kai shook his head slightly. Not here. Not now.
As the group dispersed under Kael's watchful eye, Zen's words echoed in Kai's mind: Fear and jealousy sharpen rivals into whetstones.
But this felt like something more—deliberate suppression.
Later that night, back at the mill, Zen was waiting with unusual tension in his posture. The moment Kai described the encounter, the old butler's remaining hand tightened on his walking stick.
"They are testing you," Zen said quietly. "And someone outside the academy is helping them. I sensed a foreign presence near the grounds tonight—similar to what you felt in the essence pool."
Kai sat down heavily. "What do we do?"
Zen was silent for a long moment. Then he reached into his cloak and withdrew a small, worn metal medallion etched with unfamiliar runes. It pulsed with a deep, steady power that felt… familiar. Like the Voidweave.
"This once belonged to your father," Zen said, voice low. "It suppresses signature leaks. Wear it from now on. And… there is something else you should know."
He met Kai's eyes, the firelight casting long shadows across his scarred face.
"Your parents did not send you here to hide forever. They sent you here because this world—Heaven Falls—is the only place where the shadow affinity can grow strong enough to face what is coming. The upper realm… they were its guardians. But something broke their defenses. That is why the crack opened. That is why I lost my arm protecting you."
It was the most Zen had ever revealed in one breath.
Kai touched the medallion, feeling its cool weight. "Will you tell me their names one day?"
"Soon," Zen promised. "When you reach the first true threshold of power. For now, focus on surviving the academy's games. The real hunt is only beginning."
Outside, in the deep shadows beyond the river, the mysterious scout watched the mill from a distance. He had seen the flare of shadow during the night drill. He had felt the brief resonance from the medallion.
His lips curled into a cold smile.
"The boy is ripening faster than expected. Time to accelerate the plan."
He raised a hand, and a tiny rift—barely the size of a coin—flickered open in the air beside him. A low-tier spirit beast with glowing violet eyes slithered through, marked with the same unnatural sigil that had appeared on the Riverclaw during the hunt.
The scout whispered a command, and the beast slunk toward the academy grounds, silent as death.
