You find yourself summoned from your Class-D cell for another round of testing. Following the researcher and the Security Department personnel, you make your way to the containment area of SCP-004.

As you approach the wooden barn door labeled SCP-004-1, you can't help but feel a sense of foreboding. The researcher briefs you on the importance of proper procedure, emphasizing the need for caution when handling the rusted steel keys, SCP-004-2 through SCP-004-13.

With the researcher having clearance greater than Level 1 clearance, you're allowed basic access to SCP-004-1, but the higher-level personnel are tasked with utilizing SCP-004-2 to -13, which luckily the researcher has the clearance level. The researcher's voice echoes in the chamber as they recount the chronological history of SCP-004's discovery and the harrowing events that followed.

You watch with a mixture of fascination and dread as the researcher describes the gruesome fate of those who attempted to unlock SCP-004-1 with the wrong keys. Only two survived, and even they were deeply affected by the experience.

Your heart races as the researcher mentions SCP-004-12, the key that leads to a dimension where the laws of physics and topology are drastically different. The mental health effects described send a shiver down your spine, and you can't help but wonder what horrors await those who dare to use it.

As the briefing comes to an end, you're filled with a sense of trepidation. The chamber feels charged with an otherworldly energy, and you can't shake the feeling that you're standing on the precipice of something unimaginable.

With a deep breath, you steel yourself for what lies ahead. As the researcher prepares to begin the testing, you can't help but feel a sense of dread creeping over you. Whatever awaits beyond SCP-004-1, you know that it won't be easy to forget.
