Genasi

Genasi are a condition of having elemental energy infused in you. This condition happens from people living in elemental magic conditions for a long time, or were born under special elemental conditions. This condition has been observed to be passed on to children too, but its relatively rare and seems to be based on chance as some children do inherit it, but most don't. There have been exceptions of specific bloodlines where the condition kept being passed on. There are some elements which are common, like fire, and water. but theoretically a genasi can be of many types like a fog genasi or even a light genasi, though those are a lot rarer.
