The Aons on Sel… they're all based on, I assume the Investiture in Elantris itself, all the sigils are based on the general shape of the landscape around Elantris. Could that magic work in other places based on the geography of the other places with high Investiture, or is that exclusive to Sel?
That is an aspect of the Selan magic system-- Did I say Selian or Selan? I can't remember which one we settled on, Peter knows…
Oh, Selish, that's what we settled on, isn't it, yeah, Selish magic system. This is why we have copy editors *laughter* That's a feature of the Selish magic system that, so far as I know, no one has pulled out in any decent reason for. But there's a distinct reason that could be figured out, but it's one of these things that will make sense when I explain it, but I'm not sure if it's quote-unquote "intuitively obvious to the average reader". I don't think that it necessarily is that, but it will make perfect sense once it's explained.
