Planar Lineages

Planar lineages are not a biological heritage, but rather the result of physical forms being invested with a degree of energy from one of the non-physical planes, usually celestial power from The Firmament, infernal power from the Nine Hells, or elemental energy.
Those with a celestial inheritance are called Aasimar, those with infernal heritage are called Tieflings, and those with an elemental legacy are called Genasi.
