Some thoughts on AoL technologies and knowledge coming back -- first, the white lines in the sky in TGH in the 'if' world (portal stone) (where they meet Selene/Lanfear). Those are most likely sho-wings, yes? Second, Shara could be hiding just about anything. Third, the land of the madmen -- the southern continent. Ripe with male channellers. Most promising -- moghedien mentioned interstellar travel! While clearly saidin would be just as tainted wherever they had colonized, perhaps the breaking wasn't as bad because of distance from the bore?
