You find yourself alongside two other Class D personnel, standing in front of the heavy steel door leading into the SCP-966 containment chamber. A researcher stands nearby, nervously adjusting his glasses, while three MTF guards stand at the ready, their weapons holstered but fingers twitching with readiness.

The researcher clears his throat, his voice slightly shaky. "Alright, Class D personnel, you're about to enter the SCP-966 containment chamber for testing. Remember, follow all instructions given to you by the MTF guards and report any abnormalities immediately."

You exchange nervous glances with your fellow Class Ds, your heart pounding in your chest. The weight of the situation settles heavily upon you as the door creaks open, revealing the dimly lit chamber beyond.

As you step inside, the atmosphere changes, becoming heavier, more oppressive. The air feels charged with tension as if something unseen is lurking in the shadows.

The MTF guards motion for you to move forward, their eyes scanning the room vigilantly. You take cautious steps, your senses on high alert.

Then, suddenly, you hear a faint rustling sound, like the whisper of fabric against skin. Your heart leaps into your throat as you realize you're not alone.

In the dim light, you catch a glimpse of movement, a dark shape darting between the shadows. Your breath catches in your chest as fear grips you tightly.

One of the MTF guards raises a hand, signaling for silence. You freeze, listening intently to the eerie silence that follows.

And then, without warning, they appear.

SCP-966, the hairless, elongated figures, emerge from the darkness, their needle-like teeth glinting menacingly in the faint light. Your pulse races as you watch them, a primal fear gripping you tightly.
