That's what I assumed, but wanted to make sure. Which leads to the question of the actual idea I have. Would a story about Muramasa, specifically one about the swords he made being cursed and such, lend itself to a greater Legend Rank by being a generalized "Cursed Sword"/"Cursed Weapon" story, since those exist pretty much everywhere that ever used weapons, or would it be a Fable due to being just the story(s) of Muramasa? 

I'll probably go with it regardless because I like the stories, but I'm re-familiarizing myself with them to find good details to weave into the grimoire, and wondered if I could branch out to other similar stories from other cultures.
