I don't see the Aviak Feathers drop in South Karana showing in item lookup. It has the tradeskill tag but without seeing it listed I can only assume the claims of it being used for Magician research are only hearsay. Don't really need to research it with my mage at this point but I will check back and post results and a log file if it works since I have a few of Knari's feathers stashed away. It is listed in Lucy.
