In fact, what is the difference between Arashi and Anglea? They are both raiders and pirates. Barbarians and Hill People refusing proper civilization for freedom. What is different between Arashi and Anglea? Do they have conflicts?
Paraphrasing question:
Is Anglea and Arashi the same?
NOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO
My in-game and role-play character would so much disagree with this, and since I created them both, I also disagree, but not to the exaggerated extent of my above role-play statement.
I feel that Arashi is a more "In the moment" civilization. Keyword is "In the moment". The world is being run with raiding and being a merchant as the powers of the time. Naturally, the Arashi Desert's harsh conditions and low economic power (I'd think) makes it a "Are you kidding?" scenario for all merchants. So, this leaves the Arashi with a single way of life: Death. Raiding is their specialty, and that is all they will do because that is all they CAN do.
Anglea, however, is barbaric because ice vikings. Everyone hears ships and someone has to go "Pirates?" Arashi fill in the gap of "Raiders", so here we have pirates. Angleans look backward and move forward, trying to get machinery of the past to secure their future. However, as luck would have it, trying to trade with other nations is a bit of a hassle when you live on a mountain. Although barbaric, they seek to unlock the minds of those pre-war, to become more powerful and to be able to advance forward. With an Anglean, he will take as he pleases, as he feels he will be able to do better than you with whatever you have.
