The tenth orbit arrived like a scream with no mouth.
Cael was training in the transit hub—the collapsed underground station they'd converted into a practice arena, its rusted vehicles and crumbled platforms providing an obstacle course for combat drills. Dorn stood at one end, his Absorption orbit open, ready to eat any stray attacks. Lyra perched on a suspended vehicle, her Hindsight scanning for danger while she called out corrections to Cael's form.
"Your Edge is drifting left," she said. "You're favoring your right shoulder since the fight."
"My right shoulder was the one she hit."
"Exactly. Compensate or she'll exploit it next time."
There would be a next time. They all knew it. Sera Kane hadn't pursued them into the tunnels, but she hadn't retreated either. Cael's enhanced Hearing could detect OA surveillance drones at the edge of audible range—distant but persistent, mapping the undercity's acoustic landscape, searching for the gravitational signatures that would betray the bunker's location.
She was being patient. That was more frightening than if she'd attacked.
Cael ran through his nine-orbit sequence: Weight adjustment, Impact burst, Edge projection, Sight overlay, Hearing scan, Touch mapping, Binding threads, Refraction cloak. Each one stable, controlled, integrated into a unified combat stance that the Hermit had designed and Cael had refined through sixteen hours of daily practice.
Nine orbits. More than most OA soldiers would ever achieve. And still not enough.
He pushed harder. Drove Impact through a vehicle's chassis, splitting it in half. Used Binding to hold the halves in mid-air while Edge sliced them into smaller pieces. Hearing tracked the acoustic signatures of each fragment, Touch mapped their gravitational topology, Sight overlaid emotional resonance onto the debris field—the ghost impressions of passengers who'd once ridden these vehicles, their daily commutes leaving gravitational fingerprints in the metal.
And then—nothing.
Not the absence of sensation. The presence of absence. A sphere materialized between his outstretched hands, roughly the size of a basketball, and within it, everything ceased. Not air. Not light. Not sound. Not gravity. Everything.
A sphere of absolute nothing.
Cael stared at it. His Sight orbit couldn't penetrate it—light bent around its edges the way it bent around a black hole. His Hearing detected no vibration from within—the sphere was a perfect acoustic dead zone. His Touch orbit, pressed against its boundary, reported a sensation he'd never encountered: the texture of void.
"Don't move." Dorn's voice, tight with controlled urgency. The big man had risen to his feet, his Absorption orbit flaring instinctively. His body recognized the sphere as a threat before his mind could process it—every bruise on his skin had darkened, his orbit pulling protectively inward.
"What is it?" Lyra asked from her perch. Her Hindsight was flickering rapidly, trying to predict the sphere's behavior three seconds into the future and failing—because the sphere wasn't doing anything. It was being nothing. And you couldn't predict the trajectory of nothing.
The Hermit's voice crackled through the comm unit, thin as paper. He'd been monitoring remotely from his bed, his failing Sight orbit connected to a network of sensors Lyra had installed throughout the training arena. "Emptiness," he said. "The tenth orbit. Creating spheres of absolute vacuum—total absence of matter, energy, and gravitational force."
"Inside that sphere," Cael said slowly, "what happens to things?"
"They stop existing. Not destroyed—removed. Emptiness doesn't annihilate matter. It subtracts it. Anything caught inside ceases to occupy space." A pause. "The OA's theoretical physics division hypothesized this orbit for decades. They concluded it was impossible—a mathematical abstraction with no physical manifestation. They were wrong."
Cael held the sphere for thirty seconds, studying it with every sense he possessed. Then he closed his hands, and it collapsed—not with a sound, but with a rush of reality filling the space where nothing had been. Air and light and gravity rushed back in, and the universe briefly hiccupped at having a hole in its fabric suddenly repaired.
A piece of the vehicle he'd been dismantling was gone. A clean, spherical section simply absent, the surrounding metal showing no damage—no heat marks, no stress fractures. Just a perfect round hole where matter used to be.
"That's not a combat orbit," Dorn said. His voice carried the particular weight of someone who'd absorbed more varieties of violence than anyone alive. "That's an extinction event."
Cael looked at his hands. Ten orbits. Four months ago, he'd been a Dwarf with four weak sensory channels, mopping floors in a tower. Now he could erase matter from existence.
The thirteenth orbit hummed behind the other ten, and the black ocean stirred in his peripheral consciousness, and the void's voice whispered with something that sounded horribly like pride:
Good. Keep going. You're almost ready.
