No, but she has a tempest inside her...
Interesting thing about most real-world myth: it has no canon.
People just made up words and creatures without much rhyme or reason or care for what might have gone before or what some scholar somewhere decided to put into writing.
I mean, none of these things really existed, so it's not like someone go check. "Guys, no, this is a brownie, and this is a booka, and this is a dobie, and this is a goblin, and this is a domovoi, and they are all totally different things, because look, they are not the same!"
Actually, it kinda does. It just isn't strictly enforced by someone in the Writing Room. King Arthur has Excalibur, there's a love triangle with Arthur, Guinevere, and Lancelot that ends badly for everyone, and so on. There are variations with region, and also variations with time, and the names change, but there are still common threads and structures.
Nobody worried about a scholar somewhere, but they did pass the same story around from region to region. And occasionally two versions of a story come around and meet each other, and someone gets to ask these sorts of questions. The name is just a name - you can figure out whether they are the same thing by looking at the role and qualities of the thing in the story.
The creatures are not real, but the *story* is a thing, and it changes and develops and reproduces as it gets passed around. So you can build a family tree, and eventually find out that the guy some folks called "Uncle Ted", was the same guy another group called "Robert Hastings". Or ou get to ask if Dagda's and/or Ceridwen's cauldron is the Holy Grail, and so on.
