Turned out those were evil elves/sprites/fairies who captured Northstar (Loki had something to do with it), and he was rescued and returned to Alpha Flight. Byrne did something before leaving AF where he had the Flighters trapped in Shaman's pouch, which was described as having the capability of driving a sane person mad. The only member conscious inside the pouch was Aurora. She had no dialog for the rest of the series under Byrne. Always thought he'd left the option for the next writer to have her cured. No takers, unfortunately. She'll most likely always be portrayed as mentally fragile. She, Wanda, and Lorna could start a support group.
