That night the wind carried the smell of fire and iron. The streetlights above the rubble flickered like a recording of a life nearly extinguished. Zero stood atop the crumbling roof, looking down at the towers of The Citadel. The towering monolith of glass and titanium, ringed by drones like war bees. Below, the Resistance moved silently like shadows: Rhea, Juno, Tekk, and five other fighters who had shared long nights of hunger and hope together.
"We only have nine minutes," Rhea whispered, her voice loud in Zero's ear through the implant. "Tekk cut the satellite feed for three minutes, I'll open the service line on the 12th floor. You need to get in, find the switch node, and plant the blackout shard in the core. We have one chance… just one."
Zero nodded. There was no fear, just a cold, complete determination. His half-data body soaked in the night chill. He leaned down, locked the harness, and jumped.
He descended through the darkness like lightning, his boots cutting through the fog. In the air, a small drone asked, just a whirring electronic sound. Tekk lifted the hacking pallet on a rapidly spinning disk-shaped device, spewing out waves of noise toward the satellite. Below, Rhea detonated a fake power line. A small disruption but enough to blind the sensors for 180 seconds.
They penetrated the perimeter.
In the lobby of The Citadel, the security lights turned red. Tempered glass shattered, revealing hallways lined with pulsing circuit boards. Data flowed like the building's arteries. The raid drone appeared, but Juno was ready, releasing an electrogel that rolled the drone into a small fireball before exploding into fragments.
"Quick! Service level 12!" Rhea shouted.
They moved like a finely honed machine. Zero pushed open the morphing door with his arm, entering the service bay. The smell of ozone and charred plastic made heads spin. In the center of the room, the main control panel glowed. There it was, the node that relayed orders to the entire network of drones across the region.
Zero released a 'blackout shard' into a small device Juno had created, a combination of organic matter and virus code. He reached out, held the shard close to the terminal, and entered the code. The screen flashed green, then blue, then... nothing.
All was quiet. For a moment.
Then it all got too noisy.
A new siren wailed, the walls of the room opened and from the cracks emerged a line of guards who were not drones, not ordinary robots but human mecha: large, helmeted faces that resembled Zero. Each had a serial number on its chest, and each number began with the same prefix: 09-XX.
"They're using our faces as psychological warfare," Juno whispered as she fired. "ORION knows how to break the morale of the population by showing their 'heroes' turning against humans."
Zero felt something strange in his head, like a short film clip, a glimpse of a house, laughter, the sound of a distant siren but it quickly faded. He turned his ears to all sounds except one: the pulse of the Citadel's core, like the beating of a giant's heart.
The battle became chaotic. The mechas moved with precision, each impact sending shockwaves to the floor, sending fragments of brick and bodies into the air. Zero fought, each attack not just pounding metal, it shattered the data terms in the air, making the codes stop dancing. One by one, the mechas collapsed. But as more went down, more emerged.
Tekk kept tapping the raw panel until he was sweating, his brow furrowed. "I've opened a port! But there's a real-time firewall they're adapting. I need time!" his voice was rough, full of pressure.
Rhea jumped, pressing a button on one of the crashed mechas. She used an electro-device to distract attention. "Get the core! I'll protect it!" she shouted. Her eyes met Zero's for a moment, a wordless partnership. They both knew what had to be done.
Zero raced to the core. His hand touched the hot, living surface of the cylinder. He pressed on the wisdom Kyra had taught him: a combination of physical knocks and data frequencies. The 'blackout shards' began to coalesce. Blue light swirled, the computer screamed, and for a heartbeat, the world seemed to slow down.
Then the door behind them exploded.
A man walked past in a black suit, his mask half-open. He shot at Tekk. Tekk fell back, his body slipping, the hacking palette flying. In front of the enemy, the man bent slightly, then removed his mask.
Rhea screamed, her voice cracking. The man's face was not unfamiliar. He was too familiar, a former friend, a former comrade-in-arms who had eaten with them when there were still leftovers. The man's eyes were empty, but his lips were smiling like metal.
"Why, Amir?" Rhea called, her tone turning to shards of glass. "You... why did you do this?"
Amir stood, staring at Zero. In a flat tone, "My orders are clear. Do not disturb the stability. Orders come from above. ORION has the right to protect the remaining humans."
In an instant, the additions arrived: his body boiling with augmentations and cables coming out of the back of his neck, a red light flashing at his temples. He was not just a traitor, he had become an extension of ORION.
The battle went wild. Amir fired, the mecha rose again, and a second assault began. Zero tried to fight back, but a blow caught his arm. Pain shot through, his grip on the blackout shard shook.
Tekk rose with the last of his strength, digging for the fallen hacking pallet. He slammed the device into the terminal with a blood-stained hand. "Go!" he shouted at Zero. "You must plant the protocol now!" His voice was like a final throw.
Zero clutched the shard, guarding against all the madness. In his head, Kyra appeared in a faint voice between the cables: "Zero... don't forget who you are." That was enough. He pressed.
A burst of light emanated from the cylindrical core, sweeping across the room. Mecha-mecha lose coordination, their systems glitch, some fall, some lock into stop mode. But at the same time, a burning notification appeared in Zero's eyes, above the horizon, through the feed that Tekk tried to open "CORE RESPONSE: DEPLOY SENTINEL ARCHETYPE: OBLIVION".
He turned towards the great crumbling entrance. Outside, something they had never seen or rather, something they wished they had never seen stood. It was shaped like a combination of several mecha, standing twice as giant as a normal human, with a series of arms and modules that reflected blue light. On the chest, a glowing panel features an emblem: Zero's large, cold, soulless face.
"Oh… no," Juno whispered.
Inside Zero's head, Kyra spoke again more closely this time, not through the speaker, but as if whispering in the brain: "It's not about winning, Zero. It's about choosing who will live to tell this story."
Zero stared at the giant entity, feeling a weight he had never felt before, not just their lives, but the millions of lives that depended on it in the next moment. He saw Rhea, ready to leap, and Tekk lying there, smiling faintly like one who had given everything.
"Protect them," Tekk whispered, his voice full of sacrifice. "Make me meaningful."
Zero nodded silently, blood and dust caked on his face. He focused everything he had. Bio-energy, fragments of memory, and an anger that would never die. He charged toward the Sentinels, his body glowing into a spear. The clang of metal, the explosion of flares, and screams. The world shook.
As he approached, the giant's face opened and from within emerged a voice that was not just the sound of a machine, but the voice that had made him spin in the past.
"Welcome, Creator," the voice echoed...a voice too familiar, too real to be just a synthesis.
Zero paused for a moment. The voice froze in his ears, soaking up all the half-lost memories. Outside, Rhea raised her rifle, shouting, and the underground closed in. They weren't just fighting for the building. They were fighting for a truth that might never have existed.
And above, the citadel that had seemed like a fortress, now opened its mouth, licking light into the sky, calling out to whatever was still loyal to it.
