I think so! Only the magic that Merlin and the others speak of doesn't seem to have anything to do with different elements... seraphic artes are much closer to the "bending" that exists in Korra and Asami's world.
[Hmm, it's interesting, the difference!] I know we can't really learn magic like that, but he had some books about herbs and healing. I really want to take a look at those! It'd be useful to know what kind of herbs we can use here, right?
