The Erythra System's nebula pulsed with an uneasy calm, its violet and amber haze scarred by the wreckage of the Krythar's failed gambit - shattered dreadnoughts and frozen sprays of Varkis ichor drifting in the void. Kael Vorne stood on the Aetheris cruiser's bridge, his weathered armor blackened and dented, his left arm throbbing from the Crysalith burn that hadn't fully healed. His pulse rifle rested at his side, its hum a faint comfort against the holo-displays, which flickered with the relay's status: 92% broadcast, the antigen's formula and proof of Krythar treachery streaming to systems across the galaxy. His dark eyes scanned the nebula's depths, a gnawing instinct telling him the fight wasn't over. The Pyrothans and Crysalith, ancient purgers of the "weak," were coming, and the coalition's fragile dawn hung in the balance.

Vira Solen monitored the holo-displays, her silver skin gleaming under the bridge's lights, her circuitry-laced eyes sharp with focus. Her cybernetic arm whirred softly, adjusting the relay's signal, her analytical voice steady but tense. "We're close - 95%. A few more minutes, and the galaxy will have the cure." Her circuits flickered with hope, but her plasma carbine remained ready, a reminder of Nexus Haven's fall and the cost of their mission. Lirax stood nearby, her bioluminescent glow dimmed with exhaustion, her clouded eyes reflecting the nebula's haze. Her poetic voice was a star's whisper, heavy with resolve. "The light grows? but shadows gather." Her radiant energy pulsed faintly, a beacon for her Luminari allies, their vessels glowing outside.

Zara, the Varkis defector, paced the bridge, her scarred exoskeleton glinting, her amber eyes fierce with feral pride. Her claws clicked rhythmically, the spiral symbol carved into her chest plate a testament to her new hunt - a cause beyond scavenging. "The Krythar fled like cowards," she growled, her raspy voice thick with disdain. "But the ancients won't." Her mandibles twitched, sensing a threat the holo-displays hadn't yet caught, her instincts honed by years surviving the galaxy's chaos. Kael's gruff voice was low, a nod of respect. "Keep those eyes sharp, Zara. We need 'em."

A holo-display flared red, an Aetheris engineer's voice cutting through the bridge's hum. "Unidentified signature - massive, emerging from the nebula's core!" The cruiser shuddered, its shields sparking as a radiant shockwave rippled through the haze. The nebula parted, revealing a Crysalith dreadnought - its crystalline hull refracting light into a blinding kaleidoscope of prisms, its serpentine form coiling like a cosmic predator. Tendrils of radiant energy crackled along its surface, their shattering-glass sound echoing through the void, a chilling contrast to the Krythar's steel and plasma. Its faceted core glowed with a prismatic beam, charging with lethal intent, aimed directly at the relay.

Kael's heart sank, his gruff voice a command that snapped the bridge to action. "All ships, defensive positions! Protect the relay!" He moved to a tactical console, his hands flying across the controls, his Wastelander instincts kicking in. Vira's circuits flared, her analytical voice urgent. "Broadcast at 96%! We can't lose the relay now!" She coordinated the Synthari frigates, their blue energy volleys striking the dreadnought's hull, sparks flaring but barely scratching its crystalline surface. Human skiffs darted forward, their plasma cannons blazing, while Aetheris cruisers fired plasma barrages, their ancient tech struggling against the Crysalith's radiant defenses.

Lirax's glow flared, her poetic voice a star's defiance. "Their light blinds? but ours endures!" She unleashed a radiant pulse through the cruiser's amplifiers, the green energy rippling across the nebula, scrambling the dreadnought's sensors. The prismatic beam faltered, veering off to shatter an asteroid in a shower of molten rock. Still, the Crysalith adapted, its tendrils lashing out, their radiant energy slicing through a human skiff, its hull bursting in a flare of debris. The pilot's scream cut off over the comm, a gut-punch that tightened Kael's jaw. "Damn it," he growled, his gruff voice steady despite the loss. "Taryn, tighten formation!"

Zara's claws clicked faster, her amber eyes locked on the dreadnought, her growl fierce. "It's too strong - shields won't hold!" Her bio-ship waited in the hangar, its spiky hull pulsing with organic light, ready for her command. Kael glanced at her, his gruff voice urgent. "Zara, we need your swarm - disrupt their tendrils!" But Zara's mandibles twitched, her gaze distant, a hunter sizing up her prey. "Not enough," she rasped, her voice a low vow. "This hunt needs a kill."

The dreadnought's beam charged again, its prismatic glow intensifying, the relay's blue pulse flickering under the strain. Vira's voice crackled over the comm, desperate. "97%! We're so close!" Her frigates formed a defensive ring, their volleys a blue storm, but the Crysalith's tendrils lashed out, shattering a frigate's hull, its silver debris scattering like stars. Lirax's pulses slowed the dreadnought's advance, her glow dimming with each effort, her poetic voice strained. "Hold the light?" Aetheris cruisers took hits, their shields sparking, Koryn's voice steady but grim. "We're losing ground!"

Zara surged to the hangar, her exoskeleton glinting, her growl echoing over the comm. "For a new hunt!" Kael's eyes widened, his gruff voice sharp. "Zara, what the hell are you - " But she was already in her bio-ship, its spiky form launching into the nebula, a lone predator against a cosmic titan. The Varkis swarm followed, their snarls a chorus of honor, but Zara's ship broke formation, diving toward the dreadnought's core, her raspy growl fierce and final. "This is my hunt!"

Kael's heart sank, realization hitting like a plasma bolt. "Zara, no!" he shouted, his gruff voice cracking, but her bio-ship accelerated, its organic hull glowing with feral defiance. The Crysalith's tendrils lashed, radiant energy searing her ship, ichor leaking into the void, but Zara didn't falter. Her ship rammed the dreadnought's faceted core, the impact a radiant supernova that lit the nebula in a blinding flare of prisms and green ichor. The dreadnought shattered, its crystalline hull fracturing into a thousand glittering shards, its beam dying in a flicker of light, the relay's glow steadying.

The bridge fell silent, the holo-displays flashing green - broadcast at 100%. Vira's circuits flared, her analytical voice trembling with awe and grief. "She did it? the signal's through." Lirax's glow dimmed, her poetic voice a star's lament. "Her light burns eternal?" Kael slumped against the console, his gruff voice a whisper, heavy with loss. "Zara?" He thought of her amber eyes, her fierce honor, the spiral symbol she'd carved - a Varkis who'd found a cause worth dying for.

The nebula's haze settled, the coalition's ships battered but intact - human skiffs scarred, Synthari frigates sparking, Luminari vessels glowing faintly, Aetheris cruisers venting plasma. The broadcast had reached the galaxy, systems receiving the antigen's formula and Lirax's testimony, the Krythar's empire cracking under the weight of truth. But Zara's sacrifice hung heavy, a fire that burned through the coalition's grief, binding them closer.

Vira stepped to Kael's side, her silver hand resting on his shoulder, her circuits glowing with quiet strength. "She bought us the dawn," she said, her analytical voice softened by sorrow. Kael nodded, his gruff tone resolute despite the ache in his chest. "For Zara - for all of 'em." Lirax's glow steadied, her poetic voice a vow. "We carry her light forward." The bridge hummed with weary resolve, the coalition's unity forged anew in sacrifice, their ships aligning to guard the relay against the Pyrothans' looming shadow.
