At the comment of it being such a waste, Rena just shrugged.
"I can't exactly know the mind of the old lord. It was long before my time. From my point of view, you can't afford to potentially flood the world with such swords. The effects would be pretty calamitous across the countryside."
Magic was already prolific in the world, and a wizard duel alone could endanger everyone and everything around it. If these swords were numerous in the world, as common as steel or silver, there would be alot of death on everyone's hands and destruction abound. Besides, if there were many, the ones that existed would no longer be special. Maybe the originals would be heralded or cursed in such a world, but they would certainly lose their signficance in the face of so many copies. The answer to Exon's questions would no longer be interesting.
"Flint, Flood, and Swift represent fire, water, and wind, respectively. It's worth noting that the swords tend to fit our personalities in some way. My father was a well-tempered heat in battle, and my uncle was a clever, adaptable man. So, their swords fit them well enough. Flash, Dusk, and Quake - the absolute originals - represented heaven, the underworld, and the Earth in between, so they are light, dark, and earth-powered."
Altogether, it was seven. Now, they were just about coming into town... Where exactly were they going to have Rena's legs looked at?
