Hey everyone!
I might be late but it hit me in the shower where the name Ascians may have come from. In Greek, a prefix of A can signify "not."
From this train of thought, you can break down Ascians to A-scians. In other words, "not scians." Looking at this sideways, I took this a little further, "not scions."
So we have the Scions of the Seventh Dawn and their opposites, the "Not-Scions" i.e. "Ascians."
What do you think?
