The chamber felt different before Leon even reached the bottom of the stairs.
Heavier. Not the gravitational weight of Voss's presence—something broader, more diffuse, like the air pressure had shifted underground. His ears popped twice on the descent. The unnamed energy huddled low in his core and didn't move.
Serath was already inside. She stood near the far wall with her palm pressed flat against the stone, eyes closed, silver hair loose around her shoulders for the first time since Leon had known her. The mercury-veins in the wall pulsed against her skin. She was listening to something.
Voss stood at the entrance. Watching Serath. Her arms weren't crossed—they hung at her sides, fingers twitching against her thighs in a rhythm that might have been unconscious. She looked smaller than usual. The gravitational presence was there, but thinner. Stretched.
Leon studied her from the stairwell before she noticed him. Short. Compact. Precise in how she held herself. The same profile Petra had described seeing through the window.
His jaw tightened. He stepped into the chamber.
"Where's Asha?" he asked.
"Greyward." Voss said it without looking at him. "She sent word through the service tunnel. She's found a trail. Didn't elaborate."
A trail. Asha hunting Irsa in the lower wards with nothing but her fists and whatever stage she'd been hiding behind that mid-Core Shaper mask. Leon wanted to feel reassured by that. The unnamed energy wanted him to feel reassured. Neither of them quite managed it.
"We proceed with two carriers," Voss said. "Serath. Leon. Standard dual-cycling protocol. The source's activity has increased—you'll feel more resonance than previous sessions. Don't fight it. Let the unnamed energy respond naturally and observe how it interacts with the new output level."
Standard. Natural. Observe.
Nothing about this was standard.
Leon took his position across from Serath. She opened her eyes when he sat. The silver was brighter than usual—catching the accelerated vein-light, holding it, reflecting something that looked almost luminous.
"The source is closer to the surface than last night," she said. Her voice had a texture Leon hadn't heard before—not the analytical precision, not the icy control. Something rawer. Almost reverent. "I can feel its structure. It's not chaotic. The expansion is deliberate. Organized. Like a—"
She stopped. Shook her head.
"Like a what?" Leon asked.
"Like a hand reaching upward through dirt." She said it quietly, and then didn't say anything else.
They began.

Dual-cycling with two carriers instead of three was harder. The triangle was a triangle for a reason—three points of resonance stabilizing the frequency, distributing the load, creating a balanced circuit. With Asha absent, the circuit was a line. Two points. No balance. Every fluctuation in Leon's cycling hit Serath directly, and every shift in hers came back at him unfiltered.
The unnamed energy moved reluctantly. Still frightened from the refinery, still cautious after the arm, it inched through Leon's remaining pathways like someone walking through a dark room with their hands out. His left side took the full load—Origin Force and unnamed energy running parallel through channels that ached from three days of compensating for the dead right.
Friction points flared. Hotter than before. The source's increased output was feeding directly into their session—unnamed energy from below mixing with unnamed energy from within, the two streams reinforcing each other in ways that pushed Leon's tolerance to the edge.
His left forearm started to burn. Not the fused, dead burn of his right—a living burn. Active pathways straining under combined load. He was overheating his only remaining arm.
"Leon." Serath's voice, tight. "Your output is spiking. Pull back."
He tried. Reached for the unnamed energy, tried to throttle it, to reduce the flow. It resisted—not defiantly, but reflexively. The source's resonance was pulling it forward the way a current pulls a swimmer, and Leon's will wasn't stronger than the tide.
"I can't—it's the source. It's pulling."
"Then redirect. Don't fight the current. Bend it."
He tried that too. Attempted to route the excess energy downward—through his legs, into the floor, the same discharge technique he'd used in the assessment. But the floor was different now. The source was *there*, right beneath the stone, and pushing energy downward meant pushing it directly into the thing that was already pulling.
The flow reversed.
Energy surged upward through the floor and into Leon's legs like a geyser. His core screamed. The dual currents—Origin Force and unnamed—went turbulent, crashing against each other inside his meridians, the friction generating heat that he could feel in his teeth.
His vision fractured. Not whited out. *Fractured*. The chamber split into layers—the physical space he could see with his eyes, and beneath it, superimposed, something else. A deeper architecture. Vast. The source's structure, visible through the unnamed energy's perception, rendered in frequencies his mind translated as shape and light.
It was enormous.
Not a chamber. Not a deposit. A *body*. Curled beneath the Academy, beneath the city, beneath the bedrock itself—a form so large that the chamber they sat in was the equivalent of a freckle on its surface. It was folded in on itself, compressed into a space that shouldn't have held it, sleeping in dimensions that Leon's eyes couldn't process and his unnamed energy could barely map.
And it was looking at him.
Not with eyes. With *attention*. The full, focused awareness of something that had been dreaming for millennia, now awake, now conscious, now *interested* in the tiny speck of matching energy sitting on its skin.
Leon couldn't breathe.
The source spoke.
Not words. Not intent, like before. Something more direct—a transmission that bypassed language and arrived as pure comprehension, downloaded into his mind through the unnamed energy like water through a crack.
*Fragment.*
One concept. Delivered with the weight of a mountain.
*You are a fragment.*
Leon's unnamed energy convulsed. Not in pain. In *recognition*. The same way a piece of broken glass might respond to seeing the mirror it came from. A desperate, yearning, devastating moment of understanding.
The unnamed energy wasn't just old. It wasn't just ancient. It was a *piece*. A shard. Broken off from the source at some point so distant that the memory of separation had degraded into instinct.
Leon was carrying a fragment of whatever was sleeping under the Academy.
The source was its origin. Its *parent*.
And it wanted to go home.
The pull became physical. Leon felt his body lurch forward—not voluntary, the unnamed energy dragging him toward the floor, toward the source, desperate to close the gap, to rejoin, to stop being a fragment and become whole again.
"LEON!" Serath's hands on his shoulders. Her energy—both currents, woven tight—slamming into his system like a wall. Blocking the pull. Creating a barrier between his unnamed energy and the source's gravitational demand.
He gasped. The layered vision collapsed. The chamber snapped back to its normal dimensions—stone, veins, darkness.
He was on his hands and knees. Both hands. The dead right arm had moved on its own—the unnamed energy so desperate that it had overridden the physical limitations, forcing fused pathways to conduct for a fraction of a second. His right hand was flat on the floor, and he could *feel* the source through it. Warm. Vast. Calling.
Then the pain hit. The fused pathways, forced open by sheer energetic pressure, spasmed. Leon's right arm locked—every muscle from shoulder to fingertip seizing in a cramp that bent his fingers backward and made him bite through his lip to keep from screaming.
Serath held him. Both hands on his shoulders. Her unnamed energy pressed against his—not forceful, not invasive. Steadying. The way you'd hold someone standing at the edge of a cliff.
"Breathe. Stay here. Stay with me."
Leon breathed. Blood on his lip. Right arm locked in a rictus of pain. Left arm trembling.
The unnamed energy retreated from the floor. Slowly. Reluctantly. Like pulling a child away from a window.
It was grieving.
Leon felt it—the specific, aching sadness of something that had found where it came from and been told it couldn't stay. Not anger. Not rebellion. Loss. Pure and old and heavy enough to drown in.
"I'm here," Leon said. Not to Serath. To the energy. "I'm here. We're not going anywhere."
The grief didn't stop. But the pulling did. The unnamed energy curled into his core and pressed against the inside of his ribs and shook with a frequency that had nothing to do with resonance and everything to do with sorrow.

Voss hadn't moved during the entire episode.
That registered slowly, through the haze of pain and aftermath. Leon looked at her from the floor—still on his knees, right arm slowly unlocking as the cramps subsided, Serath's hands still on his shoulders.
Voss had stood at the chamber's edge and watched the source nearly swallow him. Watched without intervening. Without cycling a single protective measure. Without moving.
"You knew that would happen," Leon said. Hoarse. Blood still on his chin.
"I suspected. When the source's output increased, I theorized it might attempt direct contact with a carrier." Her voice was clinical again. The mask rebuilt while Leon was on the floor. "The contact confirmed something I needed to verify."
"You used me as bait." The words came out unsteady. Frayed at the edges. He didn't care. "Again. You set up this session knowing the source would reach for me and you *watched*."
"I needed to know if the source would try to reabsorb a fragment. The answer is yes. That information is critical to—"
"I don't give a damn what it's critical to." Leon stood. Serath's hands fell away. His right arm hung, twitching, the cramp residue making his fingers spasm. "You stood there. You watched it pull me. You let Serath save me instead of doing it yourself because if you intervened with your energy, the source would have detected that you're a carrier too. You protected yourself."
Silence. The chamber pulsed. Deep. Slow. The source, settling back into its new wakefulness, no longer reaching but still aware. Still watching.
Voss's expression didn't change. But something behind it did—a tectonic shift, deep and invisible, the kind that only showed in the aftershocks.
"You're right," she said.
Two words. No defense. No justification.
Leon stared at her. Serath stood motionless beside him. The chamber breathed around them.
"You need to decide something, Voss." Leon's voice was quiet. The kind of quiet that came after shouting, not before it. "Are you our instructor or our handler? Because a handler uses assets and protects herself. An instructor stands in front of the thing that's trying to eat her students." He held her gaze. "You can't be both. Not anymore."
Voss didn't answer.
Leon turned. Walked toward the stairs. His right arm twitched at his side. His unnamed energy grieved in his core. His left hand was steady.
Behind him, Serath didn't follow. She stayed in the chamber, looking at Voss with an expression Leon couldn't see.
He climbed.
The stone was warmer than ever. And somewhere deep below—deeper than the chamber, deeper than the source's sleeping body, deeper than anything Leon could reach or understand—the fragment inside him wept for something it remembered and could never return to.
He kept climbing.
