Sir
I apologize for my son's rudeness; he is currently feeling a bit emotionally fragile due to a recent divorce. While that is no excuse, I feel as if I should extend an olive branch on his behalf.
In terms of magic; I always assumed that it came from Aeons - beings of great power in my homeland. However, I assisted in their needful death at home. Due to their demise, I am no longer certain of where my magic stems, simply that I am a black mage, as is my eldest son. My youngest son is already showing an affinity with white magic.
