I'm curious about what this story means by the sword only being able to be wielded by a Hero, cause I've seen 2 uses of the term in literature and they mean very different things.
1: Only the hero can wield the holy sword in that no one else can touch it, it burns them or weighs like several metric tons, something like that. Only the Hero can touch it.
2: Only the Hero can wield the holy sword in that it's just a metal stick for anyone else, in the hands of the Hero it's a true holy blade capable of smiting any foe, felling mountains and leveling trees but anyone else and it's unwieldy, off balance and awkward to use. However unlike option 1 any one can touch it and therefore move or even steal it.
