Midnight found the Obsidian Warrens shrouded in half-light, its basalt walls slick with condensation. Aris Kael led the Neon Umbra strike team through a tangle of maintenance tunnels, alloy rod humming softly at his side. Behind him moved Mara with her cyberarms poised, Eira clutching her staff, the netrunner Nyx scanning for data-traps, engineer Tuckling carrying a pack of mana-charged breachers, and ex-Warden twins Rho and Kael in the rear.
As they advanced, the tunnels grew narrower. Along the walls, faded plaques warned "Sector Seven: Guard Exclusion Zone." At each corridor junction hung pulsating motes of light—Wardens' old sentinel devices, still half-alive, projecting faint echoes of their former keepers. The first one activated with a whisper of gears and a spectral uniformed figure materialized before them.
"State your business," the echo intoned in a hollow voice. Its holographic bayonet glowed dimly.
Aris raised his rod. He let the Spiral in his palm glow and touched the cold alloy of the guard's projection. The illusion wavered, fracturing into a hundred motes of starlight before fading entirely. "We're Ghostwalkers," he said, voice steady. "Authorized by Neon Umbra."
Tuckling slipped through the gap and tapped a breacher charge against the next sentinel. With a soft pulse, Eira's rune resonated through the crystal threads of the device—turning it from watchful guardian into a benign orb of drifting light.
They pressed on into the Warrens' underbelly: a cathedral of pipes, conduits, and half-buried service pods. Every step echoed. At one crossroads, a chorus of distant voices rose—Wardens calling roll call, boots pounding on grated floors. The twins Rho and Kael mirrored each other as they swept the area, their augmented optics filtering out illusions until real guards lay revealed behind phantom walls. In silence they passed, careful not to disturb the echo-scapes.
At last they reached the Prism chamber—an antechamber sealed by a massive tri-sigil lock, overlaid with mirrored runes. A gust of cold wind swept from within, carrying ghostly laughter of Warden keepers. "They left their pride here," Mara muttered.
Eira stepped forward. With a low incantation, her staff node glowed. Aris laid his hand on the nearest sigil, Spiral and mirror-runes resonating in harmony. The lock answered with a grinding roar, panels sliding aside to reveal a circular vault beyond.
Inside, a crystalline obelisk floated above a dais of fractured obsidian veins—the Astral Prism, its multifaceted core pulsing with muted starlight. As Aris approached, the Prism sent out a wave of spectral energy. Around them, the chamber walls flickered with memories of past guardians: trials of strength, tests of honor, oaths sworn beneath lunar glow. Their whispers swelled to a crescendo.
But Nyx detected incoming footsteps—real Wardens, alerted by the breach. "Forty seconds," she whispered through her comlink.
Aris squared his shoulders and gripped the Prism's edge. It responded, locking into the Spiral's frequency, drawing millennia of warded mana into his palm. He felt the chamber's echoes fuse with his bloodline—ancient Arcanotek rites pulsing alive. With a single pulse of intent, he hurled the Prism into Mara's waiting hands.
Outside, alarms shattered the hush. The team raced back through the echo-haunted halls. Rho and Kael formed a moving barrier of kinetic shields; Tuckling set mana-breach charges to collapse pursuit corridors. Eira and Nyx provided cover—one with crackling mana-bolts, the other jamming security feeds.
They burst into a wider tunnel just as the Wardens' squad rounded the bend. Mara lifted the Prism, and in its radiance the tunnel walls brightened—crystalline runes flaring as the artifact's resonance overrode the Warrens' failsafe. The Wardens froze, their weapons slipping from numbed fingers.
Aris took a breath and turned toward the exit. "Go!" he shouted.
The Umbra sprinted through shuttered doors that slid open at the Prism's command, spilling them out into a service dome ringed by emergency hatches. Behind them, a tremor shook the underground. The Warrens collapsed in a cascade of stone and steel.
On the surface, rain fell against neon signs, hissing as it met hot air vents. The team gathered in the downpour, hearts racing, the Astral Prism cradled between them. Above, a sliver of moon peeked through drifting clouds.
Mara glanced at Aris. "You did well, heir of the Spiral. The Prism lives."
Aris looked to the dark horizon of NeoLuna's glittering spires. The echoes of the Guard had tested him—and failed. Now, with the Prism's power in Neon Umbra hands, a new current ran through the city's veins.
He tightened his grip on the alloy rod, turning its pale glow toward the rising storm of corporate retaliation. "This is only the beginning," he said.
And in the electric hush, the Spiral on his palm pulsed once more—an echo of victory, and a promise of the battles yet to come.
