The silence stretched on, deafening in its stillness. Eren stood alone in the midst of the cold, cavernous space, the remnants of his battle lingering like smoke in the air. His body ached from the fight, but the adrenaline pumping through his veins kept him upright, alert.
He couldn't shake the sensation that something was wrong. The Tower itself felt… off. He had faced adversaries before, each one a challenge in its own right, but this—this was different. The figure he had just fought wasn't just an enemy; it was an anomaly. Something out of place in the Tower's design, something that shouldn't have been there.
The quiet only deepened the unease.
Eren glanced down at the crystal in his hand, its glow now completely faded. He had used every bit of its energy in the final attack, and now it was just an empty shell, a reminder of the power he had wielded and the cost of using it. He felt a pang of loss. That crystal had been his lifeline, the connection to something beyond the Tower. And now it was gone.
"Great…" he muttered, dropping it to the floor.
The room around him seemed to shift, subtle but noticeable. The walls, once solid and unyielding, now flickered, as though they were made of shifting shadows. The floor beneath him felt unstable, as if it could crumble at any moment. The very air itself seemed to throb with an unnatural pulse, as though the Tower was alive, aware, and—most unsettling of all—watching.
He stepped forward cautiously, his senses on high alert. The oppressive stillness that had enveloped the area after his victory was slowly being replaced with a growing sense of tension. The deeper he moved into the floor, the more the feeling intensified. The Tower was changing, warping in response to his presence.
A distant hum vibrated through the walls, and a small screen flickered to life on the far side of the room. Eren approached it warily, instinctively reaching for the weapons he'd been carrying since the first floor. But there was no enemy waiting for him, no trap set in motion. Only an empty, blinking screen.
"System update," it read, the words cold and detached.
Eren frowned. He had seen these before, brief moments of pause when the Tower recalibrated. But this time felt different. There was something strange in the air, something that made his skin crawl.
He touched the screen, and the message shifted, revealing something new.
Warning: System Corruption Detected
The words flashed briefly before being replaced with a series of indecipherable symbols and lines of code. Eren squinted at the screen, trying to make sense of it, but nothing about the message was familiar. He had seen the system's warnings before, but this was… something else.
"Corruption?" he muttered, running a hand through his hair. "What does that even mean?"
Suddenly, a series of sharp, mechanical clicks echoed from above, followed by a low, rumbling growl that seemed to come from the very foundations of the Tower. The floor trembled beneath him, and the walls cracked open with a deafening screech. Eren stumbled back, his heart racing.
The Tower was shifting. More than that, it was breaking apart.
From the fissures in the walls, strange tendrils of dark energy began to seep into the room. They twisted and writhed like living things, pulsing with an eerie light. The air grew thick with their presence, and Eren instinctively took a step back, his mind racing for a solution.
"What the hell is happening?" he whispered.
The tendrils slithered across the floor, their movement fluid, like oil moving through water. They didn't make a sound, but their presence was suffocating, like the entire room was being consumed by them. Eren reached for his weapons again, but something stopped him. His instincts told him not to fight—not yet. This wasn't a battle he could win with force alone.
Then, just as quickly as they had appeared, the tendrils retreated, fading back into the cracks in the walls from which they had emerged. The hum of the Tower grew louder, a strange, distorted symphony of mechanical and organic noise that filled the space.
Eren stood frozen, trying to process everything. What had just happened? And why was the Tower reacting like this? The entity he had faced before, the one that called itself an "anomaly," had clearly triggered something within the Tower. But was this just a side effect, or had it set something much larger in motion?
Without answers, he had no choice but to move forward. The Tower was no longer just a place to climb—it was becoming something else. Something far more dangerous.
Eren took a deep breath and began walking, his every step echoing in the vast, empty space. He didn't know what awaited him next, but he was certain of one thing: the Tower was no longer just an obstacle to overcome. It was a force of its own, and its true nature was only beginning to reveal itself.
And if he didn't find answers soon, it would consume everything.
