CHAPTER 187: INTO THE HEART OF THE ISLAND

The morning after the basin’s awakening broke with a strange, muted stillness—an eerie quiet that felt less like the calm before action and more like the island itself was listening. The sun had only just begun to rise, pale gold leaking through the thick canopy overhead, but the expedition camp was already alive with activity. Students moved through the trees with disciplined urgency, packing gear, checking weapons, rolling up reinforced tents, and double-checking health elixirs whose colors shimmered faintly under the early light. The air hummed with unspoken tension, as though everyone felt the weight of the previous day’s discovery lingering over them—the colossal obsidian "spire," half-swallowed by terrain and sealed with runic panels no one on the island could decipher.

But no presence in the camp radiated more pressure than Arios Pureheart.

He stood at the edge of the treeline with Lucy and Liza at his sides, his expression unreadable, his eyes fixed on the path that led toward the interior—toward the forest that now seemed darker, deeper, and somehow less familiar than before. His posture was steady, but the tightened grip on his gauntlets and the faint, nearly imperceptible tremor in the air around him betrayed the truth: whatever lay ahead was tied to something that connected to him more deeply than he let on.

Lucy adjusted the straps of her dual scabbards, her crimson hair tied back so tightly that not a single strand moved even with the morning breeze. Her expression was sharper than usual, not tense but hyper-focused, the kind of gaze she only wore when she sensed danger approaching—not directly at them, but circling them.

Liza, on the other hand, moved with calculated precision. Her staff hummed faintly with detection spells, and she occasionally traced symbols into the air, leaving trails of shimmering silver that dissolved after a second or two. She didn’t speak, didn’t rush, didn’t even frown—she simply observed. And the deeper they walked into the forest, the more her silver eyes hardened.

The forest did not behave like a forest should. Birds no longer called. Wind no longer whistled. Even the insects had gone still.

Something had changed overnight.

Something huge.

The teams fanned out in a diamond formation, with Arios’ trio at the lead, several elite sub-teams trailing behind, and scouting members flanking both sides. The instructors followed at the rear—not out of caution, but because they silently acknowledged that Arios, Lucy, and Liza were better suited to react to an unknown danger with speed that faculty support would only slow down.

They moved deeper.

Deeper still.

And with each step, the landscape shifted.

Where Phase Two’s forest had been lush and alive, Phase Three’s interior twisted into something older, denser, and unnervingly symmetrical. The trees grew in spiral patterns, the branches curving inward like skeletal fingers reaching for a point ahead. The ground sloped gradually downward, forming a wide, natural corridor that funneled them toward the heart of the island.

By midday, the sky overhead had almost completely disappeared behind interlocking branches, turning the path into a vast cathedral of shadow and filtered green light.

Arios felt it first.

A pulse.

A faint thrum under the earth, like the heartbeat of a colossal creature buried beneath them.

He stopped walking.

Lucy froze at the same instant. Liza’s grip on her staff tightened.

Another pulse.

Stronger this time.

A vibration that rippled up their legs and into their chests, as though something deep underground was trying—no, pushing—to resonate with them.

Behind them, several students stumbled. A few clutched their heads. Others simply blinked rapidly, the sensation making their vision blur.

One student whispered, "The island is... humming?"

But Arios didn’t speak. Couldn’t speak. His throat tightened, his heart racing in a pattern that didn’t feel like his own heartbeat. His body responded instinctively—his mana stirred, rising unbidden, as though reacting to a presence he did not remember, yet felt intrinsically familiar.

Lucy touched his arm. "Arios."

He blinked, grounding himself.

The pulses stopped.

But the silence that replaced them felt heavier, denser—charged with intent.

Liza lifted her hand toward the earth. "It’s shifting. The mana flow beneath us—it’s redirecting. Gathering. Forming a channel toward—"

She stopped.

Her body stiffened.

And when her eyes opened, glowing faint silver, she breathed one sentence:

"—toward the structure."

The Fallen Spire.

The same monument that had awakened the basin. The same edifice that had responded to Arios’ presence with that slight, inexplicable hum.

The instructors stepped forward, exchanging grim looks. They knew what this meant. Whatever lay ahead was no longer a simple exam. Something ancient had recognized the students’ presence—and now, it was drawing them in.

They pushed on.

The descent into the island’s heart continued, becoming steeper and narrower, the air thickening with mana so dense it shimmered faintly like heat. Strange markings appeared on the bark of the trees—spiraled glyphs of an unknown language that glowed faint blue whenever Arios neared them.

Liza noticed immediately.

"They’re reacting to him," she murmured.

Lucy nodded. "Not the island—these symbols. They’re... acknowledging him."

Arios didn’t react outwardly. But inwardly, a cold realization took shape.

This island wasn’t just ancient.

It was remembering him.

The corridor of spiraled trees finally ended—abruptly, unnaturally—opening into a massive clearing that looked nothing like a natural landscape. The ground was perfectly circular, the soil compressed as if by extreme weight or impact. At the center, partially buried beneath tangled vines and broken stone, lay another segment of the Fallen Spire.

But this one was different.

The basin’s structure was massive but dormant.

This one was awake.

A faint, rhythmic glow pulsed beneath the surface—echoing the heartbeat-like thrum they felt earlier. The obsidian panels were more refined, layered like armor plating, with runic grooves carved with surgical precision. A towering crack ran down its left side, leaking wisps of pale blue mana that drifted like smoke.

Everyone stared.

No one spoke.

Arios stepped forward.

And the structure responded.

Panels shifted.

Dust rose in a spiraling vortex.

Runes lit up in cascading waves.

The instructors shouted for teams to hold formation, but no one moved because—

The structure wasn’t reacting aggressively.

It was responding like a door unlocking.

The ground shook—just once, but enough to send several students stumbling backward. Then the earth split open in front of the spire fragment, revealing a descending path of obsidian stone steps that sank into darkness.

A tunnel.

A deliberately constructed one.

Liza inhaled sharply. "This isn’t natural. This is an entryway. Someone built this."

Lucy’s voice softened with something close to awe. "Not someone. Something ancient."

The light beneath the structure flickered—once, twice—then focused in a single beam that illuminated the staircase.

Arios could feel it calling to him.

Lucy saw this immediately. She stepped in front of him, placing a hand on his chest.

"You’re not going down there alone."

Liza moved beside her. "Nor ahead of us. If this place reacts to you, that means it can target you."

He looked between them.

He wanted to protest—reflexively—but stopped.

Because the fear behind Lucy’s eyes wasn’t overprotectiveness.

It was instinct.

They descended as a trio.

The staircase spiraled downward, the temperature dropping with every meter. The walls were carved with the same glyphs from the forest, but here, they formed connected patterns—constellations of symbols that pulsed softly with embedded mana. Every ten steps, the runes changed shape, shifting into new configurations as if recalibrating to the presence of the students.

The deeper they went, the more Arios felt it:

A memory he didn’t have.

A sensation he couldn’t place.

Something ancient inside this structure recognized him—not as an intruder, not as a threat, but as a returning element. A catalyst.

Lucy sensed his tension. She moved closer, her hand brushing his. "Stay with us."

Liza whispered, her voice low. "This is... more than an exam."

After several minutes of descent, the stairway opened into a vast subterranean hall.

The chamber stretched wider than any academy lecture hall, with towering columns shaped like spiraled roots turned to stone. The ceiling arched high overhead, lit by strands of blue luminescence that flowed like rivers across the surface.

At the far end of the hall stood a massive circular door—three times taller than Arios—composed of layered obsidian plates arranged like the petals of a steel flower. At its center lay a single depression—a small, round indentation barely large enough for a hand.

A handprint.

Arios stepped forward.

The room trembled again.

Lucy and Liza exchanged glances—not stopping him, but readying weapons instantly.

Arios raised his hand.

Then—

A sound.

Soft.

Subtle.

Like a whisper slipping through stone.

It wasn’t a language. It wasn’t words. It was resonance—an echo that slipped into the mind rather than the ears.

And in that moment, Arios realized something impossible:

The island wasn’t calling to him.

It was recognizing him.

He placed his hand into the depression.

Light surged outward.

The layered plates began to unwind, rotating in perfect synchronization, unlocking mechanisms older than the forest above. The ground shook, dust raining from the ceiling as the massive door folded open—revealing a corridor lit with the same shifting mana veins.

Lucy exhaled sharply. Liza swallowed hard.

Arios took a breath.

And they stepped inside.

The corridor stretched long and straight, the air thick with mana that tasted metallic at the back of the throat. Strange devices sat embedded in the walls—discs, spires, crystalline nodes that hummed faintly as they passed. None were active, but all felt dormant, slumbering, waiting.

Until Arios approached them.

Each device flickered awake, runes shimmering to life as though acknowledging his presence.

Lucy muttered, "I don’t like this."

Liza whispered, "This place is responding specifically to him. That can’t be a coincidence."

Arios didn’t respond.

He was too focused on the growing sensation in his chest—an instinctive pull drawing him deeper, guiding his steps without hesitation.

At the end of the corridor, the trio reached a wide chamber shaped like a circular amphitheater. At its center lay a raised platform composed of interlocking plates, each carved with runes that curved inward toward a single central point.

A dais.

A focal point.

A—

The ground trembled violently.

Lucy and Liza moved instantly, taking defensive stances.

Arios did not.

Because something within the platform activated—not aggressive, but awakening.

Light spread across the runes in patterns that mirrored a heartbeat.

Arios stepped closer.

Lucy shouted his name.

Liza grabbed his arm.

But the platform reacted before either could pull him back.

A column of light erupted upward, engulfing Arios completely—pure white, tinged with blue, so bright that Lucy and Liza had to shield their eyes.

The hum grew louder.

The platform vibrated.

And a single phrase—not spoken aloud, but resonating directly in the minds of all three—echoed through the chamber:

"Designation Found."

Lucy’s eyes widened.

Liza froze.

Arios’ vision blurred, drowned in light.

Then—

Another message.

Clearer.

Older.

Colder.

"Initiating Recognition Protocol—

Candidate Returned."

The entire chamber roared with power.

And Phase Three’s true challenge finally began.
