The cell is a 3x3 box. The walls and floor regenerate (with double-thick cobblestone) and the roof is too high to reach. The prisoner respawns in the cell using the squilly bed glitch. Visitors enter via the ceiling.
Outside Defence
The prison is surrounded by a bunch of chunkban items in chests. The guards can filter more chunkban items into chests on the inside of the prison to cause fear to the escapists.
More Security
The guard areas have ... a layout. There is a sustainable milk supplier to give the guards infinite milk. There are many elder guardians in a particular part of the prison that give Mining Fatigue 3 constantly.
