The stairwell descended for what felt like kilometers, each step echoing in the darkness. Arthur's flashlight beam cut through dust motes that danced like tiny ghosts, and behind him Team Alpha moved with practiced silence—five lethal shadows following their commander into the unknown.
The air grew colder as they descended, carrying a sterile quality that reminded Arthur of sealed medical facilities.
"How deep does this go?" Nyx muttered.
"Pre-war Ark construction specifications called for minimum depth of two hundred meters," Anis replied, her voice distorted by the narrow passage. "We're probably at one-fifty right now."
Alisa bounded ahead, her enthusiasm undimmed by the oppressive darkness. "This is so exciting! A real Lost Sector! I wonder what we'll find?"
"Hopefully not a structural collapse," Scarlet said dryly.
The stairwell finally terminated at another reinforced door. This one opened easily when Arthur approached, its sensors detecting movement and activating with a mechanical hum that suggested independent power sources still functioned.
What lay beyond stole Arthur's breath.
A city stretched before them—or rather, a city's skeleton. Pristine white prefabricated structures rose in ordered rows, their surfaces unmarred by time or weathering. But something about them felt profoundly wrong. They were too clean, too uniform, lacking the organic imperfections of real architecture. Like a child's model city, built from identical blocks.
"It's beautiful," Lyra whispered, her recorder already documenting.
"It's fake," Arthur corrected. "Look at the construction. Those buildings aren't meant to last. They're temporary shelters, probably erected while the main settlement was being excavated."
Nyx whistled low. "So this whole place was just... what, a waiting room?"
"A failed one," Anis said, scanning her surroundings with tactical precision. "Raptures must have reached them before the permanent structures were completed. Everyone either evacuated or—"
A shriek echoed across the artificial cityscape.
Arthur's M-99 Saber snapped up instantly. "Combat formation. Alisa, with me. Scarlet, right flank. Nyx, left. Lyra and Anis, elevated position."
The team moved like clockwork. Alisa's concealed weapons systems activated with mechanical precision—chainsaw blades extending from her forearms, rocket pods rising from shoulder mounts. Her cheerful expression never wavered.
Raptures emerged from the prefab structures like insects from a disturbed nest. Dozens of them, then hundreds—assault-class units with chitinous armor and blade-appendages, moving with coordinated purpose that spoke of higher intelligence directing them.
"Contact!" Scarlet called, her rifle barking three-round bursts that dropped Raptures with surgical efficiency.
Nyx's Screamin' Eagle launcher roared, the rocket obliterating a cluster of units and sending prefab debris flying. The fragile buildings crumbled like paper mache, white fragments cascading down in artificial snow.
Arthur fired controlled shots, his Saber's enhanced targeting systems guided by his Omni-Tool's tactical overlay. Each pull of the trigger sent a Rapture spinning to the ground, neural cores shattered.
Alisa laughed—actually laughed—as she dove into the swarm, her chainsaw blades tearing through Rapture armor with horrifying efficiency. "This is amazing!"
"Stay in formation!" Arthur ordered, but he couldn't deny the effectiveness. Alisa moved with inhuman speed, her Mishima engineering pushing beyond standard Nikke specifications.
The battle shifted as a larger presence made itself known. A Lord-class Rapture emerged from the central structure—bipedal, heavily armored, standing three meters tall with blade-arms that gleamed like obsidian. Not as dangerous as a Tyrant, but formidable enough to warrant respect.
Alisa's face fell. "Oh. Just a Lord-class."
"Just?" Nyx laughed, reloading. "Kid, that thing could tear through most squads."
"But Commander kills Tyrants," Alisa said, pouting with genuine disappointment. "I wanted to see him fight something really big."
Arthur smiled despite the situation. "Focus. Standard Lord-class engagement protocol. Nyx, suppressing fire on the torso armor. Scarlet, target joint articulation points. Alisa, when I give the signal, full assault."
The Lord-class charged with surprising speed. Arthur stood his ground, Omni-Blade igniting in his left hand while his right tracked targets with the Saber. The Rapture's blade-arm swept horizontally—Arthur ducked, feeling the displacement of air above his head, and drove the Omni-Blade upward into the exposed joint.
Energy crackled. The Lord-class shrieked.
"Now!"
Alisa moved like lightning, her blades finding every weakness Arthur's strike had created. Scarlet's precise fire took out the creature's optical sensors. Nyx's rocket struck center mass, and the Lord-class collapsed in a heap of smoking metal.
The remaining assault-class units retreated, their coordination breaking without higher-level direction.
"Sector clear," Arthur called. "Sweep and secure. One section at a time."
They moved methodically through the prefab city, clearing buildings that crumbled at the slightest impact. Each structure housed more Raptures, but none organized. It took hours, but finally they stood before the central building—larger than the others, marked with pre-war command insignia.
"This was going to be their Central Command," Anis said, reading the faded designations. "Priority storage, administrative functions, probably the Harmony Cube vault."
Arthur's chest tightened. For Lyra. For Anne. "Let's find it."
The interior was dark, powered systems long since failed. Arthur's flashlight revealed corridors lined with storage crates, office equipment still arranged as if workers had simply stepped away for lunch.
They found her in what would have been the command center.
A woman sat cross-legged on the floor, surrounded by Rapture parts arranged in meticulous patterns. Her limbs were clearly augmented—Rapture components grafted onto Nikke frame with crude but effective skill. A tattered black bodysuit covered her frame, and a katana rested across her lap.
Her eyes opened as they entered. Golden, like many Nikkes, but holding depths of pain that made Arthur's heart clench.
"More of you," she said, voice hoarse from disuse. "Come to finish what Rose started?"
Arthur raised a hand, signaling his team to hold. "We're not here to fight. I'm Commander Arthur Cousland, Monarks, Special Commandos. This is Team Alpha. We're investigating this Lost Sector."
"These are Scarlet, Lyra, Nyx, Anis, and Alisa."
The woman stood in one fluid motion, katana gripped loosely. Her gaze swept across the squad, dismissive, until it landed on Scarlet.
Everything changed.
"You," she hissed, and moved faster than Arthur could track.
Scarlet barely got her rifle up before the katana struck, the blade carving through the weapon's stock. Arthur lunged forward, Omni-Blade igniting as he intercepted the next strike.
"Stand down!" he ordered both parties. "Nobody shoots! That's an order!"
The woman's blade met his Omni-Blade with a shower of sparks. She was good—better than good—her movements precise and economical despite the Rapture parts limiting her mobility.
"It's all your fault," she snarled at Scarlet. "Rose did everything for you! She killed all of us for you!"
"I don't know what you're talking about!" Scarlet shot back, circling with her sidearm drawn but not firing.
Arthur parried another strike, his goddesium legs providing stability as he absorbed the impact. "Talk to me! Who are you?"
"Gayle," the woman said, pressing her attack. "Melee Squad. We were the experimental unit, the ones they sent to die because we cost too much to maintain!"
Arthur's mind raced even as his body fought. He shifted tactics, moving defensively, letting Gayle expend energy while he gathered information.
"Our commander," Gayle continued, her strikes growing wilder, "had orders. Send us on impossible missions until only one remained. Rose found out. She snapped. Killed everyone—the squad, the commander, everyone except her precious sister Scarlet who she couldn't bear to harm!"
Understanding crashed over Arthur like ice water. "Stop," he said quietly. "Please, just stop and listen."
Something in his tone made Gayle pause, her blade hovering centimeters from his throat.
"The Scarlet you knew isn't this Scarlet," Arthur said carefully. "Look at her. Really look. My Scarlet was converted in recent years, after the first invasion ended. She's barely been active for a few years. She wasn't even alive when your squad was deployed."
Gayle's eyes flickered to Scarlet, truly seeing her for the first time. Different face. Different build. Different weapons—an SMG, not melee equipment.
"She just shares the name," Arthur continued softly. "I'm sorry for what happened to your squad. It's a tragedy that should never have occurred. But this Scarlet is innocent."
Gayle's blade lowered slowly. "She... you're telling the truth."
"I am."
The katana clattered to the floor. Gayle sank to her knees, decades of rage draining away to leave only exhaustion. "I survived. Blew the entrance to keep more Raptures out. Used the Harmony Cube to fix myself with Rapture parts when I couldn't find proper replacements. I've been here, guarding this place, waiting for..."
She didn't finish. Arthur knelt beside her, his prosthetic hand resting gently on her shoulder. "You did your duty. More than anyone could ask. But your war is over. Come with us. The Outpost welcomes all Nikkes. We just need the Harmony Cube. Gayle, can you lead us to it?"
Gayle looked up at him with broken eyes. "The Cube is gone. Used. I'm sorry."
Arthur's heart sank—for Lyra, for Anne—but he pushed the disappointment aside. "It kept you alive. That matters."
He activated his comm. "Shifty, this is Cousland. Lost Sector secured. Request transport for resource extraction and one additional passenger."
Shifty's voice crackled back. "Confirmed, Commander. Transports en route. ETA forty minutes."
Arthur stood, offering Gayle his hand. "Welcome to the Ark. We take care of our own."
Gayle stared at the offered hand—goddesium and black, a prosthetic like her own cobbled-together limbs—and slowly, hesitantly, accepted it.
