Nice explanation of magic. <3

One thing I was raising my eyebrow at is the Sylphs however.
Sylphs are the elemental spirits of air, with their Queen living on the tallest mountain. But they seem to be attached to Terra element, as well as the forest and air. Is there a reason you have it this way? Curious to know.

(Also, where are the Undines, Salamanders, and gnomes?)
