Thancred in particular makes reference to this. I assume he refers to Y'shtola, Papalymo, Yda, Urianger, and himself in particular based strictly on context. The organization at the Waking Sands was called The Path of The Twelve in 1.0, I believe. But I don't recall having this Students of Baldesion thing explained. The familiar characters from 1.0 who were with The Path and aware of The Echo were said to have been those who had fled Sharlayan, and little more. Did I miss an explanation of these terms / this group somewhere along the way?
