The Genasai, Aasimar and Tiefling

'''When the outer planes come in contact with the prime material planes, the living beings of both planes are affected. It is well documented in dwarven history that the elemental wives taken by the sons of Moradiin  resulted in the half elemental dwarves known as the Genasi.'''

'''It is also rumored of the intermixing of angels and devils with humans, either directly or through dark deals. Aasimar are rare and mostly unheard of (though the kings of thoril have been rumored to be of divine. Tieflings are slightly more common, especially in the great desert empire of Sæm A'non'''
