Rhapsody (paraphrased)
How much freedom do you get from Brandon for the maps and symbols and so on?
Isaac (paraphrased)
I get a lot of freedom with the maps. There were actually times we've changed parts of the books to fit the maps.
Rhapsody (paraphrased)
May I have an example?
Isaac (paraphrased)
We changed around directions in the Kholinar chapters a lot.
Rhapsody (paraphrased)
And the glyphs and other symbols?
Isaac (paraphrased)
For the glyphs I have a symmetry tool which I play around a lot with. We developed the glyphs later in full from those images we liked.
For the Allomantic symbols I had a couple different ideas which didn't seem to work well. Then I had an idea about a bunch of nails lying around haphazardly and from that image the Allomantic symbols evolved.
