The Akademi’s perimeter hummed, a low thrum of invisible force fields and automated sentries. Bayu vaulted over the final barrier, landing with a jarring thud that sent a spike of discomfort up his spine. Mud caked his shredded collar, and the jade lens felt like a slab of river ice in his palm. Sirens and rotor wash had faded past the perimeter ridge, leaving only the real gauntlet ahead. He burst into the central dome, the vast holographic display of the ‘Perisai Langit’ — the global defense network — shimmering above. Tirtawijaya’s neon sprawl pulsed beneath a simulated sky, marred by a single, rapidly growing crimson sphere: the primary celestial rock. A red warning banner scrolled across the bottom: *IMPACT IMMINENT – ESTIMATED WINDOW: 72 HOURS AND CLOSING.* Chandra stood at the control console, shoulders rigid, his usually immaculate hair slightly disheveled. Nenek Ratih sat in a high-backed chair, her gaze like a laser. Neither spoke, but static bit the dry air between them, sharp as ozone. “I have it,” Bayu said, his voice raw, holding up the jade lens. It gleamed faintly in the low light. “From Ibu’s research. The ‘Alat Penyeimbang.’ The harmonic component for the Siphon.” Nenek Ratih’s lips thinned. “You vanished for two days, Bayu. Two days while the Sampar clan flooded city broadcasts and our Aegis squads scrambled. And you return with a bauble, claiming it belongs to her lost work?” “It’s not a trinket!” Bayu stepped forward, lifting the green facet into the glow. “She designed this to channel kinetic load. Our current grid is cracking under the advance fragments. This is our only shot at stopping Jovan’s catastrophe.” Chandra turned, pupils dark as wet coal. “Your ‘methods’? You understand nothing, boy. You are a reckless distraction. Her research was unstable, unfinished. It got her killed.” “And your traditional methods led to *her* being hidden away, didn’t they?” Bayu shot back, the words laced with years of resentment. “To leaving me in a ten-meter flat while you managed planetary equilibrium from a throne! Brute force won't bleed velocity off a falling asteroid. Ibu knew that. She found a smarter method.” “Silence!” Chandra’s shout rattled the metal deck beneath them. “You dare question this bloodline? You, who couldn't balance basic kinetic feedback two weeks ago?” Bayu dug his nails into his palms. “I dare, Bapak. Because your legacy rests on locked vaults and half-truths. She died because you were too rigid to adapt. Jovan runs corporate sabotage, and you're holding a ceremonial shield. We need the Siphon. I can build it. *I* can run it.” A tense silence descended. The only noise was the low digital rumble of the incoming strike on the holo-projector. Chandra stared, jaw rigid, before something like grim recognition settled across his brow. Nenek Ratih leaned forward, a subtle smile playing on her lips. “Well, well. It seems the little grub has finally found his voice.” She turned her piercing gaze to Bayu. “The Alat Penyeimbang, you called it? A fine name for the jade focusing lens. I knew of it. She gave me her full schematics before her final deployment. I waited until you stopped dodging hard labor and began looking at the real cost.” Bayu stared at her, dumbfounded. “You… you knew? All this time?” “Of course,” she said, her smile widening into something predatory. “Did you believe an operative of her caliber leaves work half-done? Or that I wouldn't secure it? This estate isn't a museum, Bayu. It is an anvil. Your father drowned in protocol. You, at least, possess the nerve to cheat when the rules fail.” Chandra scoffed, but the anger had lessened, replaced by a weary resignation. “Manipulative old viper,” he muttered, but without true venom. “So, you’ve played us all, Nenek.” “It’s called strategic mentorship, Chandra. Something you would do well to learn.” She gestured to the console. “The schematics for the full ‘Perangkat Sifon’ are ready. We have precious little time. Bayu, show us what your mother truly envisioned. Chandra, put aside your pride and lend your expertise. This isn’t about Angkasa anymore. It’s about ensuring there’s an Angkasa left to inherit.” For the next thirty-six hours, the three of them worked in a frantic, unholy alliance. The grand hall transformed into a high-tech workshop. Bayu tracked the blue holographic line-drawings mapped over the metal grating, steering fabrication drones with quick, jerking sweeps of his hands. Chandra grumbled through his teeth while recalibrating high-capacity induction coils, his grasp of heirloom tech unquestioned. Nenek Ratih leaned on her cane, catching mismatched solder joints before the drones sealed them. They finished the rig before dawn: a faceted pillar of polished Noctium alloy housing crystalline veins built to drink massive kinetic shocks. The jade lens clicked flush into the crown with a dull magnetic snap, buzzing against Bayu's fingers. It wasn't built to blast anything; it was built to bleed the falling mass dry. As the final power conduits locked into position, the entire hall shimmered with a pale, emerald light. Bayu smeared grease off his forehead, his fingers twitching with fatigue. “It’s ready,” he muttered. On the ceiling map, the red orbital track expanded, swamping half the projected skyline. The warning banner flashed violently: *IMPACT IMMINENT – 24 HOURS. TRAJECTORY UNCHANGEABLE. ALL DEFENSE PROTOCOLS HAVE FAILED. ESTIMATED GLOBAL EXTINCTION EVENT: 98% PROBABILITY.* They had built their salvation, but it seemed the world was already beyond saving.
