"Sometimes the other planes manifest themselves into beings during birth, infusing their blood with their power. The Genasi are one such people, the offspring of genies and mortals"

Genasi - MoF

Genasi, the result of common races breeding with genies, are a rare race on Iyvis, but they are known of by even the most mundane towns person. They come in four varieties, Air, Earth, Fire and Water, often thought to be linked to the mysterious elemental crystals found throughout the world.

They are generally only found in larger cities of mixed races, but they do have their own smaller towns further out from the main areas on the different continents, but these are very secluded and other races are rarely made privy to their existence.
