I have elementals in my world. They are basically just normal people with slightly changed features. They are not a part of their element, but are merely born with the ability to control it and move invisibly within it. Though I have not written anything with them yet, they would typically be portrayed as good.

When you say "elementals" what do you mean?

^^Yes. Do you mean elemental type creatures, or elemental type magic?

I don't think I have any elemental creatures in Ritharael (I might; but I have none yet.)

For magic, nearly all magic in Ritharael is elemental. Each of the seven races has a natural skill in one of the elements that corresponds to the different regions of the land they were made to take dominion over. Elemental magic comprises of using that skill along with magical energy and a proper shape to channel the magic through, and then having enough concentration and knowledge about how the element works in order to manipulate it. So that's the rough summary about how I portray them in my world, if that answers your question...

I have elemental dragons in one of my shorter stories that I'm planning on recycling into a full novel. They're not really magic, though. There's nothing mystical about their abilities - they just do. As in, the sky dragon has a special gland that produces electricity, and it can spit lightning, and the water dragon can spew large quantities of a boiling liquid with huge amounts of force, etc.

Did I misunderstand the question?

This novella I'm working on (and planning to self-publish), Dreamwalkers, will kind of have Elementals in it--there are four wolf packs representing all four elements, and they each have special abilities to go with those elements. The wolves from the Air Pack have the abilities of walking on air/flying and controlling weather (though just slightly, and only in a small area at once). The Earth Pack can, obviously, control earth and trees.
The Fire Pack can call fire out of nowhere, and walk through it unharmed.
The Water Pack can breathe underwater.

*ponders * I've wondered about having elementals, as a form of angel/demon who had manipulated a substance to give themselves form. But still not something I'm sure I want to do. Thoughts to process.
