I was perplexed for a moment until I realized that Quintessence is just another name for what I was taught under the name of Aether :) I am sure there are a group of elements that belong to that class as well, since there are six colors in total on the periodic table Briar displays.

As a substance that is neither quite air nor fire but rather a mythological, deified something-sort-of-in-between, I am sure that magical elements under the categorization of Quintessence must be exceptionally powerful, though rather difficult to harness and control. It's definitiely a cool addition to think about!
