Elementals are seemingly powerful beings. They are implied to be incredibly old by Yagorath (▶️), who doesn't consider the ancient Makoa to be that old (▶️). They can be trapped within gemstones somehow. Their magic seemingly originates from Nature; the same place Leipori and Warder magic comes from. Little else is known about them.
