Essentially, it's this: A sword that, when held and drawn, the blade ignites into flames that do not harm the holder. It inspired various myths about such weapons, including: The weapon weilded by Freyr (which later ends up being used by the fire demon Surt), the angel(s) which guard Eden, and more recently, Eragon Bromsson's sword Brisingr.
