Classes

The Blackhawk Academy has a credit system. Everyone started with 20 credits and gained more by doing activities that were called 'mission' assigned to one by the academy. 

The missions were normally something simple as 'Help clear the pond', or 'Help move desks from one classroom to the next', but they could also be quite complex sometimes.

Of course, the harder the mission, the more credit one got for completing it.

The credits could be used for the extra functions of the academy other than just normal classes. From buying Essence resources to being allowed inside a library, everything used credits.

So, everyone worked extra hard to gain as much credit as they could.

On the other hand, not attending a single class, unless one had previous clearance, made one lose credit for it. If they missed a whole day, they could easily lose anywhere from 5 to 8 credits depending on the number of subjects they had to go through.
