The Light Knight

The first warning came as a color, not a sound: the streetlamps along the seawall stuttered from amber to sickly green, as if the city’s veins had forgotten what they were carrying. Rain fell in patient sheets, turning the neon signage into long bruises in the puddles, and every reflection looked like a wound you could step into.

Eryx Halden ran anyway.

His boots found purchase on tar-paper slick as oil, his cape snapping behind him with the metallic whisper of its reflective lining. The cracked visor over his face caught the city’s light and fractured it, sending thin bands of gold skittering across HVAC units and rooftop gravel. Each time he pushed the suit for speed, the canister strapped to his ribs answered with a quicker tick-tick, like a clock that took offense at being ignored.

He’d been a man once who believed in mornings. He still did, in the way a person believes in an old song: not because it will save you, but because it reminds you that you once had something like safety.

Below, at the grid authority substation, floodlights swept the chain-link yard in slow, authoritative arcs. The grid authority didn’t just keep the lights on; it policed failure. Their security teams arrived before fire crews. They sealed gates, seized recordings, assigned blame. Tonight, their drones joined the police drones above the street, a second set of eyes that would rather tag him hostile than admit they needed him.

A siren warbled and died. Another tried to start and choked on dead air.

Eryx dropped to a crouch near the roof’s edge and stared down through rain at the substation’s main doors, where an ambulance had pulled up crooked, as if it had been shoved into place. He recognized the vehicle by the scuff on the rear panel and the way the side light flickered on the beat of its own exhaustion.

Mina Sato stood in the open side door, shoulders squared inside her yellow jacket, head bent toward a patient Eryx couldn’t see. Even from this height he could read her hands: fast, deliberate, refusing to tremble. Her radio earpiece glinted when the floodlight hit it. She looked up once, not searching the roof so much as daring the night to send her something worse.

Eryx felt the old pull toward her, sharp as hunger and just as impractical. She was a rule he broke because the alternative was to let people die alone. She was also the only person who spoke to him like he was still human.

A shape moved near the breaker yard—white raincoat, too bright against the wet dark, as if the darkness itself was trying to spit it out. The Luminar paused beneath a floodlight and lifted a hand, almost gentle. Pale dust drifted from his glove, catching in the air like spilled starlight before it settled on the slick pavement and began to glow.

Phosphor. A trail.

Not a clue for later, not a riddle for a board—an arrow drawn in light for someone who couldn’t stop chasing it.

Eryx’s suit gave a brief, shivering pulse, the core canister at his ribs ticking faster, and he tasted metal at the back of his throat as the charge climbed and threatened to crack the glass along its hairline fault. Down below, Mina leaned out of the ambulance and shouted something into her radio—sound swallowed by rain, urgency unmistakable.

The Luminar turned his masked face toward the seawall district, toward the old tunnels that breathed brine beneath the streets, and then he looked up.

Even through the fractured visor, Eryx felt that gaze land like a hand on his chest. In the yard, the floodlights swung closer. Drones adjusted their angles. Mina’s head snapped toward the substation gate as if she’d heard a countdown begin.

Eryx could take the roofline and drop straight into the yard, closing the distance to the Luminar before the trail vanished into the tunnels. Or he could get to Mina first—help her get her patient out before the substation tripped and the waterfront went dark—and risk letting the Luminar walk into the city’s throat with his bright, patient dust.
