Max studied the blueprints of the central prison seriously and found the concept of going in and freeing Asiva and Severus to be nearly impossible.
The central prison was built just 3 kilometres away from the army regiment, meaning any breakout attempt by force could be contained by the military.
It was patrolled by tier3 and 4 guards and had a tier5 Jailer present on ground at all times.
The holding cells were all built underground in a cold and damp place so that neither natural sunlight nor fresh air ever graced the prisoners.
There were 3 underground prison levels with many security features like mithril iron gates and guard quarters.
In addition to all these features, the individual gate to each cell was made from 15 inch thick steel and was designed in a way that every opening or closing of the gate made a shitton of noise which meant that stealth operations were impossible even if one had the key.
