Hi! Random person- 

Okay not really. I'm Exit's other 'friend', and I'd like to ask a few questions mostly about the history of behind the scenes stuff. 

Is there any way to know how exactly the powerful families disappeared? 
What about the powers they mostly wield? (Including the De Silva family) 
Ethnicity of each family? 

Then questions about the forbidden powers; was there certain events or happenings that caused them to be branded as 'forbidden' or do they just decide it's too OP and are like, "Yeah, no."

EDIT: AH! AND I FORGOT ONE MORE QUESTION!!! 
Since I wanted to make a captain (fight me guys if you want it), I also wanted to ask if it was okay to make my character also the head of a division that deals with research? Or are the captain positions army-related only?
