Astarion's accent is Transatlantic....which is a manufactured American accent mostly associated with old money types.
Is it really? I actually had no idea--it sounded English to me. You learn something new everyday! Nevertheless, I like it.
Yeah, when it was manufactured they wanted an accent that vaguely sounded European. It is a deliberately designed prestige accent.
That's incredibly silly but also very fascinating. I recognize the accent now that you've pointed it out (Winchester in M*A*S*H speaks with it) but I never would have guessed that it was an intentionally manufactured accent to denote wealth. But this is the kind of accent variety (in games) that keeps things interesting. I'm hoping we get some more accents from around Europe. Welsh, Scottish, French, and German, in particular.
