You stand at the entrance of SCP-015's containment area, flanked by two security guards and a Class D personnel. The air feels heavy with the weight of the unknown, and a sense of unease settles over you as you prepare to venture into the depths of this enigmatic anomaly.

Your flashlight casts feeble beams of light into the darkness ahead, illuminating a tangled maze of pipes, vents, and boilers that stretch out before you. The rusted metal and twisted shapes seem to writhe and pulsate in the dim light, giving the impression of a living, breathing entity.

The Class D personnel, visibly apprehensive, hesitates at the threshold, but the firm grip of the security guards pushes him forward, forcing him to take the first step into the unknown. His footsteps echo hollowly against the metal floor, a stark contrast to the oppressive silence that surrounds you.

As you follow behind, you can't shake the feeling of dread that gnaws at the edges of your mind. Every creak and groan of the pipes sends shivers down your spine, and you can't help but feel a growing sense of foreboding with each passing moment.

The Class D personnel, guided by the security guards, navigates the labyrinthine corridors with cautious steps, his eyes darting nervously from one shadowy corner to the next. You can see the fear etched on his face, a silent testament to the terror that lurks within SCP-015's confines.

Suddenly, a low rumble reverberates through the maze of pipes, causing the Class D personnel to freeze in his tracks. His breathing quickens, and you can see the panic rising in his eyes as he struggles to maintain composure.
