Ok, some form of raw dark magic I can understand, but the ability to summon a cursed weapon? If you mean the necklace is a Greek fire ([i]which is a weapon, not a mystical flame[/i] - I have to emphasize this) in disguise I'm cool with that, but to have Greek fire appearing on her hands out of nowhere or even controlling its flame is stretching my tolerance level for Mary Sue-ish characters too far. I believe that she has no whatsoever relationship with Hephaestus, who is the god of fire.
