A quick swipe across his wristband projected a layout of the archive onto his goggles. His target glowed faintly on the map: a relic stored deep within the restricted section. He adjusted his grip on the grapple gun and whispered, "Alright, baby. Let's make some history."
With a hiss of compressed air, the grapple's hook shot across the expanse, embedding itself into a girder on the opposite side. Kael clipped the line to his belt and zipped silently over the vast chamber, his shadow flickering across the glass walls like a phantom. Landing with practiced ease, he quickly deactivated the motion sensors along the corridor with a device that crackled faintly against the wires.
He approached the final vault door, a monolith of silver alloy etched with symbols that seemed to shift under the dim light. Kael's pulse quickened. This wasn't just any vault; it bore the mark of the Infinite Mirror, a relic whispered about in hushed tones even among the most seasoned thieves. A tool of unimaginable power, they said, capable of bending reality itself. If the shard was here, it could change everything.
Kael reached into his pack and retrieved a small black cylinder—a pulse decoder. Attaching it to the door's locking mechanism, he activated it with a press of his thumb. The device hummed, sending waves of energy rippling through the circuits until, with a soft chime, the vault door slid open.
Inside, a single pedestal stood bathed in light. Atop it rested a fragment of glass no larger than his palm, its surface shimmering with a kaleidoscope of colors that seemed to move of their own accord. Kael stepped closer, his gloved hand trembling as he reached for it.
The moment his fingers brushed the shard, a searing pain shot through his chest. Kael staggered back, clutching at his heart as visions flooded his mind—alternate lives, countless versions of himself, each one locked in a different struggle. He saw himself as a soldier, a scholar, a beggar, a tyrant. The images flashed faster and faster until he fell to his knees, gasping for air.
"Kael Draven," a voice echoed in his mind, deep and resonant, "you have touched the Shard of the Infinite Mirror. Beware the path it will carve for you."
The shard pulsed in his hand, and Kael forced himself to his feet. The vault's alarms blared to life, crimson lights bathing the chamber as automated turrets descended from the ceiling. "No time for existential crises," he muttered, tucking the shard into a hidden pocket and sprinting out of the room.
As he dodged the turret fire and vaulted over barriers, Kael felt the shard grow warm against his chest. Shadows twisted in his peripheral vision, forming into a figure running alongside him. He turned his head and nearly tripped over his own feet.
It was him. Or rather, a version of him, clad in battle-worn armor and carrying a blade that shimmered with the same ethereal light as the shard.
"Stop!" the doppelgänger shouted, his voice raw with desperation. "You have no idea what you've done! Put it back before it's too late!"
Kael skidded to a halt, staring at the apparition. "Who the hell are you?"
"I'm you, idiot," the figure snapped. "And if you don't listen, you're going to doom us all."
Before Kael could respond, a squad of enforcers stormed into the corridor, their weapons trained on him. The apparition vanished like smoke, leaving Kael to face the reality of his predicament.
"Drop your weapons and surrender!" barked the squad leader.
Kael raised his hands, a wry smile playing on his lips. "Alright, boys, but just so you know, I'm terrible at staying arrested."
With a flick of his wrist, he activated a flash charge, blinding the enforcers as he leapt through a nearby window. Glass shattered around him as he plummeted toward the bustling lower levels of Zephyris. His grapple gun fired instinctively, latching onto a rail and swinging him to safety.
As he landed on a crowded platform, Kael felt the shard pulse again, a haunting reminder of the warning he'd just received. He couldn't shake the feeling that his life had been irreversibly altered. Somewhere in the depths of his mind, the voice from the shard whispered once more:
"The mirror shows all, Kael. Even what you'd rather not see."
