I've played this through twice now, the second time largely for the plot, and there's a worldbuilding issue I'm still confused by. Is Syl'anar supposed to be a global economic and tech powerhouse, or an isolationist hermit-empire? They have ads advertising discounted elf-slaves for emigrants, yet the rest of the world seems to be almost totally ignorant of the practice. Does no one offer Elves asylum because Syl'anar's so mighty they don't dare, or because it's too obscure and weak to have any geo-strategic rivals who'd bother?
That's really the only false note, and the general lack of foreign public opinion on the issue. The MC obviously has to start as a naif for the plot to function, I'm not sure how one might reconcile that. Still, otherwise the world hangs together better than most fantasy novel series' I've read.
