Subject/s: D-96845 female, 25yrs, equipped with a headset with a connection to control, a camera mounted to the side of the headset, and a hand held torch as well as a satchel for anything recovered or found inside scp-5212.
Subject is instructed to enter scp-5212, with the front door being left open. Subject then moves through the main hallway, the camera activates and shows the darkly lit hallway, with piles of clutter taking up most of the floor space.
The subject then turns a corner as instructed, showing an even longer hallway, with doors on either side. The subject is ordered to proceed, as the subject enters the hallway, out of sight of control, all scans lose contact, and any indication of their existence besides the camera and vocal feed is gone.
The subject continues down the hallway, each door viewed is wide open with the camera picking up even more clutter being hoarded within each room. A textbook is viewed by the subject. Control then orders them to pick it up and view its contents. The book is shown to have writing of an unknown language, control then orders the subject to keep the book and bring it back with them.
Subject is then ordered to venture deeper inside scp-5212. As the subject finds their way to the end of the hallway scans pick them up again. Determining that they have returned to this dimension, they then turn the corner, which has now brought the subject back to control. Control then orders the subject to exit scp-5212.
Post expedition report: subject D-96845 retrieved a textbook from inside scp-5212. The contents of the book are assumed to be that of writing, researches are in the process of attempting to decipher the language, but without further content, this will take some time. Nothing living was viewed inside scp-5212. It appears that the interior dimensions of scp-5212-1 change, in an attempt to ward out any intruders, further expeditions are required to determine the exact size of scp-5212-1.
