The prisoner sits on a 3x3 platform, of which the middle block regenerates upwards using a basalt generator. They respawn using the squilly bed glitch. In the room they are in, the roof and walls are too far to reach, the walls regenerate upwards, and there is lava on the floor which is also too far to reach. Guards have clear vision from all around the room using glass hallways. The visitor enters the cell from above.
Outside Defence
Around the prison there are many zone protection items in glow item frames. These will repeatedly kick anyone who gets too close to the prison. They are also placed around the nether side of the prison. Above the prison is a roof detector, which will either turn on a light or trigger a suicide (sort of) depending on whether AFK mode is activated. Below the prison, there is a pearl glitch detector as well. There are many timed elder guardians all around the prison, which give Mining Fatigue 3 constantly.
More Security
Guards will run a ban check on the entrance hallway to make sure there are no invisible players sneaking behind. There are numerous killchecks for the visitor, and the guard always has clear visibility on them through glass. When the visitor finishes their visit, the items from the locker will be moved to them, and they will be allowed to leave, somehow.
