for the eye i've always thought that whatever they initially intended it for he merely used it to safely "force" himself to a greater potential early. he barely channeled a thread before the eye but early in the TGH he's accidentally using portal stones which verin doesn't feel strong enough to use although she can later travel. maybe she was lying and just trying to prod him into using the stone however it always seemed logical. :)

i'd never considered a continuing use for it though. interesting :)

i always assumed that this particular dragon banner was a ter'angreal tied to the horn anyway.

hoping that hawkwing does influence tuon. mat blows the horn. and rand orders hawkwing to scold his decendent about the injustice of slavery etc :)
