The brown LED grows stronger when your hand gets near.
You notice that you feel compelled to pull in a way that you might not in real life. It immediately feels like the chain is fighting against you, so you fight back for a bit, eventually getting a vague sense in the back of your mind to have some patience when you get nowhere. As you ease up, the resistance shows you patience in turn, letting you remove a section of chain without further incident.
The machine parts are starting to make a small pile on the floor.
While you pulled, various still images flash across the screen. It occurs to you that these are moments that Andrew has observed of you that are significant to him, such as you attempting to saw away at Kaoru’s straitjacket straps in Ellie’s projection, speaking with you in private, and when you first ‘greeted’ the group in the main hall.

The center screen violently distorts itself before dissolving entirely, morphing before your eyes into a regular PC monitor like the other two. The group might miss the reveal of seven locked folders appearing on the center screen when deafening noise* - what one could imagine to be the screaming of rusted machinery - drills into everyone’s ears the second that the last warden is finished.

Your vision is affected soon after in stutters, everything in sight jittering with analog noise and distortions, making it difficult to accurately judge how to hold onto anything, or even tell how big the room is. The gravity is now oppressive, making you take great effort for just the smallest of movements. Despite the projection turning incredibly hostile at a moment’s notice, you’re overcome with the feeling that your presence is hurting it.
The brown light shuts off, and a new group of four LED lights appears within the cavity: purple, yellow, teal, and a conspicuous gap of darkness.
