The Prometheus Staff ("Apple of Idun" in the Chuang Yi edition) was a legendary artifact created by Master Dvali and used by the alchemist Fay Kanavion when she faces off against the warlock Fenris Fenrir in Geffen's triennial Tournament of Magic. It, along with Skrymir the Golem, was destroyed by Fenris' Laevatein staff at the conclusion of their match.
