The element of air is associated, in mystical theory, with "thought"
For the purposes of this story, I'd ask you to forget that AIC says Galus was 130 in the OAV series, if you knew about that. If you didn't, I'd ask you to forget I even mentioned it.
I can see where Afura would be good for almost any pondering, and I don't mind the Wanderers definition of a heavy reader. In that sense, the author brought it out fairly well, without having to carry extra baggage from Wanderers I DON'T care for (the silly "competition" with Shayla, the overall bitchiness, etc...)
You need to see all of the El-Hazard animated series to even vaguely understand this, okay?
Since there doesn't seem to be a definitive map of the Alliance kingdoms, someone probably ought to draw a "fanon" (fan-canon) map, if they haven't already.
FWIW, I've assumed/hoped that Roshtaria and Gannan shared a border in my fan fiction.
The reason that I don't understnad most of the stuff that goes on around here is because, even though I love El Hazard, I don't know much about it, so therefore, I get confused easily.
Now, to get started on That Farmer Guy That Rune Venus Likes...
