Magic in the Leif & Thorn universe interacts heavily with spirits, who range from “majestic and imposing” to “tiny and adorable.” (Lookit that tough little Cthulhu-type guy at the top.)
Water and fire spirits appear to grow right out of their respective elements. Nature spirits are more inclined to have stuff growing on them.
(These aren’t the only varieties. For instance, Holly’s major connection is with star spirits, not shown.)
