Elementals
Elementals can roughly be defined as spirits inhabiting un-living matter, though they are infinitely more complex than that. A water elemental isn't just moving water with a mind of its own! Once the matter is possessed by an elemental, it becomes the body of the creature and forms complex organs just like regular organic creatures body. It take days or weeks for an elemental to properly develop its body when it first inhabits it.
Because of Felarya's magical nature, most elementals are able to animate huge mass of matter, making them gigantic. And because an elemental needs a lot of energy to maintain its form, they need to eat a lot. They hunt pretty much anything that is living and that they can consume. Their body is moldable, which means that their throat, mouth and stomach can stretch quite a bit, allowing them to swallow large preys.
Elementals are extremely hard to kill. If you fight one in its own element, the task can become all but impossible because the elemental will use the surroundings to sustain itself. Even if you manage to severely damage its body, the elemental will just leave it and search for another chunk of matter to animate in a quieter place. However, once an elemental spirit has chosen a type of matter, it will never been able to use another type. A fire elemental will never become an ice elemental, for example.
The only sure ways to get rid of an elemental is to either devour its spirit (but creatures able to perform that trick are rare) or use a banish spell once the spirit is separated from the body, to take the spirit away. Using opposite elemental magic is also a good way to damage them (water vs fire for example). There is no existing spellcaster strong enough to harm an elemental using its own element (aside from the Coldfire used by some very rare beings, among them the succubus Arale).
How intelligent and conscious an elemental is varies enormously from one specimen to another. There is some spirits barely aware of themselves and some with a mind closer to a god than a human's. There is also a wide range of personalities as well, from a grumpy earth elemental to an impish and friendly lightning one.
