Three elemental spirits are known in Black Clover. We know Sylph chose Yuno when she had the chance. Salamander, the fire spirit, has left Fana of the Diamond Kingdom and has decided to support Fuegoleon. The most recent addition to the group of discovered elemental spirits is the water element, Undine. Undine supports the ruler of the Heart Kingdom, Princess Lolopechka.

While the term “sylph” is something that might be a little familiar, “salamander” and “undine” are particularly unusual names. Is there someplace where these mythical beasts were previously associated? As it turns out, there is one place in history where the characters first meet, and it is not recent.

The philosopher Paracelsus died in the 1500s, and a book was published after his death. In this, he made element and mythical creature associations. He paired wind with the mythical creature, the sylph. Fire, he matched with the salamander, and water was paired with the mythical creature, the undine. Since all of these unusual characters (called by these specific names) appear in Black Clover, we can draw some correlation with where the manga author got inspiration.

This history is fascinating to Black Clover fans because, in addition to these element representations discussed so far, the philosopher had one other element. Along with the sylph, the salamander, and the undine, Paracelsus also wrote about the element of the earth and paired with it the mythical creature, the golem.

After considering the golem as the next elemental spirit, the only question remaining would be to ask ourselves where to expect it. Sylph chose Yuno from the Clover Kingdom. Fana and Salamander were paired in the Diamond Kingdom, though when her “elf” self was gone, so too was the spirit. And lastly, Lolopechka and Undine are from the Heart Kingdom. As the story moves onward, both the fourth elemental and the Spade Kingdom remain out of sight. But for how long?
