The General's dilemma...

Bismoil district, Outer area, Near the SSA.

A tall and sturdy wall enchanted with magic and made up of various magical materials surrounds the whole SSA to prevent the beasts from running outside of the area. This not only helps in maintaining the safety of the Bismoil district, but it also helps in better monitoring of the area. 

There are only two gates in these walls, one facing towards the north from where these beasts are put inside every three months. The army captures a large number of beasts in the northern border area and transports them here to train the soldiers.
