Imperial Defense Academy was unnaturally silent. 

The corridors where third years discussed their enlistment and choice of planet service were almost empty. 

In the vast campus, cadets were only seen in the training facilities. 

Of course, this was the case for third years and a significant portion of second years. 

Most of the first years were still going about their routine. 

Common Classes for general, yet important knowledge continued. Recently, they were taught about the survival guide in case one was lost in a Dungeon alone. 

The tactics a cadet could employ in such a situation: Using beast cores to hunt an enemy, mastering various herbs to produce targeted baits and basic repair in case their cadet comm was damaged.
