I see it as my duty to help you out; Durmstrang is actually located in the northern parts of Scandinavia! It does not accept muggleborns, though. However, it seems to be focusing mainly on the dark arts, and they have students from Bulgaria, among other countries. Counting that Draco's father was considering sending him there, we can assume that the school is more focused on an aptitude for the dark arts and magic, not so much where the students come from.
And asdfghjklø I just love your drawings.
