For some reason when I designed these banners I had the idea that they would have been used and designed primarily during the God Wars, but it makes far more sense for them to have been designed earlier, along with their uniforms.  It is, however, true that Ishar and co. did not have any banners until shortly after the God Wars, so I may have just been confusing the two issues.

You can also see my initial concepts for her hands on the side there.  I had to work on them a little more, of course, but the basic idea of pinky finger = wing finger remains the same.
