Chapter 52: Sneaking into the cave

Chapter 52: Chapter 52: Sneaking into the cave

The Eternal Frostblade in his ring pulsed again.

Stronger this time, sharper, as though the retelling of its own history had stirred something long dormant back toward wakefulness.

Then..

**BOOM!**

The entire academy shuddered, the sound rolling through the stone like a struck bell.

The floor lurched violently beneath their feet, throwing Lyra off balance and sending a hairline crack racing across the nearest wall.

Somewhere in the distance, students screamed, their voices carrying up through stairwells and open corridors in a rising wave of panic.

Windows rattled hard enough that Theon feared for a moment the glass might shatter outright.

A second explosion followed almost immediately, deeper and heavier than the first, the kind of sound that came from somewhere far beneath the ground rather than anywhere close to the surface.

Theon stumbled sideways and caught himself against the wall, palm pressed flat to stone that was still faintly vibrating.

Lyra nearly lost her footing entirely, only Lazeria’s quick grip on her arm keeping her upright.

Lazeria gasped, eyes darting toward the nearest window as though she could somehow see the source of the tremor through solid stone.

Ifrith’s fur bristled from head to tail, every hair standing on end, his earlier embarrassment forgotten entirely in the face of something far more urgent.

"What was that?" Lyra shouted over the settling rumble.

Another tremor rolled through the mountain’s foundations, softer than the first two but no less unsettling. Cracks spread further across the corridor floor, spider-webbing out from some central point Theon couldn’t identify. A fine drift of blue-tinted dust sifted down from the ceiling, catching the light like falling snow.

Theon didn’t wait for anyone to suggest it he was already moving toward the nearest window, footsteps quick against the trembling floor.

What he saw stole the breath from his lungs.

Far below, across the academy’s central grounds, a massive section of earth had caved inward, stone and packed frost shattering apart in jagged fragments to reveal an opening that plunged straight down into darkness. Not a simple sinkhole. Not a collapsed cellar.

An underground tunnel, wide enough to swallow a full company of soldiers.

No! wider than that. An underground chamber, judging by the way the opening flared outward beneath the surface, exactly the shape a vast cavern would leave if the ceiling above it finally gave way after five thousand years of holding its secret.

The same place from the story.

Theon stared down at it, disbelief warring with a dawning, cold certainty in his chest.

Eiralyth stepped up beside him without a sound, her reflection joining his in the rain-streaked glass. Her expression had lost every trace of the softness from before, settling into something grave and watchful.

"Yes," she said quietly, confirming what he already knew without needing to ask. "That is what I was talking about."

Below, students were already gathering at the edges of the courtyard in tight, nervous clusters, pointing and murmuring toward the crater with expressions caught somewhere between terror and fascination.

Instructors moved through the crowd with practiced urgency, shouting for everyone to fall back, herding students away from the collapsed ground with hands and spellwork alike.

Blue barrier runes flickered to life around the perimeter of the opening, ancient academy wards responding automatically to a breach they’d probably never anticipated having to seal.

Theon felt it before he could name it. A pull, subtle but undeniable, threading up from somewhere deep beneath the academy’s foundations, brushing against the edges of his awareness like a hand reaching through stone.

The fragment in his ring was answering.

Not violently. Not yet. But the connection between the two halves felt unmistakable now, a thread drawn taut across five thousand years of separation, finally close enough to pull.

His hand moved to the storage ring almost against his will, fingers curling around the cold metal.

The Frostblade trembled once beneath his touch.

Then again, harder.

And somewhere far below, from the black mouth of the newly opened chamber, a second pulse rose to meet it... faint, ancient, and utterly certain of what it had been waiting for.

Lyra’s voice reached him from somewhere behind, small and uncertain in a way that didn’t suit her at all.

"Big brother..."

Theon didn’t look away from the crater, he couldn’t have if he’d tried. The wind pulled at his hair through the cracked window, carrying the faint scent of frost and old stone up from the depths below.

The ancient tunnel had opened.

The academy courtyard had come apart at the seams.

Instructors moved faster than Theon had ever seen them move in a classroom, shoving students back into ragged clusters, robes snapping as they barked orders across churned earth. Blue barrier runes flared and stuttered along the broken ground in overlapping arcs, throwing cold pulsing light across the courtyard and making every shadow twitch like it had a life of its own.

At the center of it, the crater breathed.

There was no better word for it. Cold air rolled up out of the dark in slow waves, carrying the smell of old stone and something colder underneath it, something that didn’t belong to any season Theon knew.

He could still feel the pull. Insistent now, threading up through his palm from the ring pressed against his hip. The fragment inside was answering something buried far beneath the academy’s floating towers something old enough to remember a war fought before the empire had a name.

Something that had been waiting a long, long time.

He turned back to Eiralyth, keeping his voice level despite the tremor still running through the stone under his boots.

"You still haven’t told me how one sword became two fragments."

She didn’t look away from the crater. The pulsing light caught her eyes and for a second she looked less like flesh and more like something carved out of ice.

"Because the clans couldn’t draw it out."

"What do you mean?"

"When the woman collapsed," she said, quiet enough that he had to lean in to hear her over the shouting, "both clans tried to claim the Eternal Frostblade. They poured mana into the seal. Ran ancient rituals. Burned treasures and blood on it."

"And it still wouldn’t move?"

She nodded, slow and grim.

"The sword didn’t recognize either of them."

A chill worked through Theon that had nothing to do with the frost drifting up out of the crater.

"So what did they do?"

Whatever warmth had been in her expression back in the corridor was gone now.

"They used the blood of the two lovers."

Lyra’s hand rose to her collarbone. Lazeria took a step back, as if putting distance between herself and the words would soften them.

Eiralyth kept going, unhurried, like she’d decided the story didn’t deserve to be softened in the telling.

"The man’s blood was taken from his corpse. The woman’s was taken while she was still alive."

Theon’s jaw tightened until it ached.

"They turned their love into a sacrifice."

The wind rising out of the crater seemed to thicken around that word, pressing against them with something close to weight.

"They still couldn’t fully claim the blade," Eiralyth went on. "But the ritual let them split its power."

Theon looked down at the ring on his hand not a tool anymore, not in his eyes. Half of something torn apart by grief and greed five thousand years ago.

"One fragment stayed here," she said.

"And the other?"

"Went to the royal line descended from the second clan."

The pieces clicked into place with an almost physical weight.

"The Imperial Palace."

She nodded at once.

For a moment everything connected the sword sleeping beneath the academy for five thousand years, the fragment that had been sitting in his ring since the palace, the broken pieces of prophecy Eiralyth had only started to unravel, the raw fear he’d seen on the headmaster’s face less than an hour ago.

Theon breathed out, and his breath fogged in air that had gone noticeably colder since the crater tore open.

"So the academy and the imperial family were tied together from the start."

"Yes." Eiralyth’s gaze lifted toward the floating towers, pale stone catching the storm light until they looked almost fragile against the darkening sky. "The two clans eventually formed an alliance. Together they built the Imperial Academy."

Lazeria frowned. "After everything that happened?"

"Not out of trust." Something bitter crept into Eiralyth’s voice. "But Out of fear."

Theon listened, each new piece settling into a wall he was only now starting to see the shape of.

"They were afraid that if either clan got hold of both fragments, the balance would break."

"So they split the danger between them," Lyra said, barely above a whisper.

Eiralyth nodded again. "And to keep either side from betraying the other, they swore a blood oath. A covenant, passed down through generations."

Understanding settled over Theon’s face like something cold and final.

"And now that covenant’s breaking."

Eiralyth didn’t answer. She didn’t have to. the alarm bells started to ring somewhere overhead, the frost still crawling across the courtyard stones no matter how many barrier runes the instructors threw up all of it answered for her.

A shout cut through the noise.

"Move the students back!"

"Activate the second barrier!"

Theon looked at the crater again, its dark mouth still exhaling that slow, patient cold into the storm-lit sky. He couldn’t tell himself this was curiosity anymore. Something in him was being pulled toward that opening, plain and simple.

If the second fragment was really down there, so were the answers to the headmaster’s fear, to the sword sleeping in his ring, to everything that had been circling him since the moment he first pulled that blade free.

He squared his shoulders.

"I’m going down there."

Lyra’s hand shot out and closed around his sleeve before he’d finished the sentence.

"So am I."

Lazeria stepped up beside her, arms crossed, chin lifted in a way that dared him to argue.

"You’re not leaving us up here."

Ifrith leapt from the ground to Theon’s shoulder in one smooth motion, eyes gleaming red in the crater’s pale light.

"I was never planning on letting you go alone."

Theon looked between the three of them, and something warm cut briefly through the dread sitting in his chest. He nodded once, and that was that.

A calm voice spoke from just behind him.

"Then you’ll need one more."

Theon spun so fast his boots skidded on the frost-slick stone, catching himself at the last second.

Leon stood there, unreadable as ever, hands loose at his sides.

"When did you get here?"

Leon blinked, unbothered. "A moment ago."

"I didn’t hear you."

"That was the point."

Ifrith’s fur bristled along his spine, ears pinning back as he studied Leon with open suspicion. Closing that kind of distance without a sound wasn’t just quiet. It was a skill, and not the kind most people picked up unless they needed it for something specific.

Theon pointed at him. "You do that a lot?"

"It’s a skill."

Lyra muttered, just loud enough to be heard. "Somehow that makes it worse."

Leon didn’t acknowledge her. His attention stayed on Theon. "I know about navigating tunnels better than most students here. If you’re going down, I can be useful."

Theon studied him for a long moment, weighing the offer against everything else the day had already thrown at him a headmaster’s face filled with fear, Ifrith’s fiancée who turned out to be a primordial demon, a sword with five thousand years of tragedy locked inside it. Trust was getting more expensive by the hour.

But they didn’t have time to be careful about it.

"This is temporary," Theon said, flat, leaving no room to misread it.

Leon nodded once. "That’s all I need."

At the edge of the courtyard, instructors kept forcing students back into tight lines while barrier mages worked in pairs, weaving wards along the crater’s rim. In all that noise nobody was watching the narrow maintenance stairwell tucked against the northern wall.

Theon spotted the gap almost immediately too convenient to be an accident.

"This way."

The five of them peeled off from the crowd, slipping down a side corridor and two flights of narrow stone steps before coming out behind a section of wall that had partly collapsed in the earlier tremors. Cold air rushed up to meet them, sharp with that same ancient scent of frost and buried stone.

The tunnel opened ahead of them, dark and waiting.

Behind them, faint but unmistakable, the academy’s alarm bells started ringing, their deep tone rolling out over the grounds in slow, heavy waves.

They dropped down without stopping to think about it.

The passage sloped down sharply, forcing them to brace against the walls every few steps. Ancient stone stretched into the dark on either side, carved with runes so worn only fragments of their shapes remained. Frost coated the floor in a thin unbroken sheet that crunched under their boots.

The deeper they went, the colder it got, until every breath came out as fog.

Theon’s ring pulsed with each step. Faint at first, then stronger the further down they went.

Once.

Twice.

A third time.

The second fragment was close now. Close enough that he could feel it pressing against the edges of his mind patient, ancient, and fully awake.

Far above, at the jagged rim of the crater, a lone figure stepped into view against the grey storm light.

The headmaster.

His deep blue eyes swept over the broken ground the scattered runes, the retreating students, the maintenance stairwell standing open where it shouldn’t have been.

Then his gaze sharpened and locked on the tunnel entrance below.

He’d seen them.

Without hesitating, he stepped over the crater’s broken edge and started down after them, his silver robes catching the wind like a banner trailing him into the dark.

Far below, deep in the winding throat of the tunnel, Theon stopped short.

Ahead of them the passage opened into a vast cavern lit by a strange blue glow that seemed to come from the stone itself rather than from any torch or rune. Pressure rolled through the air, pressing against his chest, his lungs, something deeper than either.

The Eternal Frostblade shuddered inside the ring, hard enough that he felt it through the metal, and through his skin, into bone.

Not rage.

Recognition.

Theon stared into the glowing dark stretching out ahead of them, his pulse loud in his own ears.

And behind him, somewhere up the long winding tunnel they’d just descended, and another presence was closing the distance. Steady. Unhurried and Certain.
