Fire Genasi

Descended from efreet, the genies of the Elemental Plane of Fire, fire genasi channel the flamboyant and often destructive nature of flame. They show their heritage in their skin tones, which can range from deep charcoal to shades of red and orange. Some bear skin tones common to humanity but with fiery marks, such as slowly swirling lights under their skin that resemble embers or glowing red lines tracing over their bodies like cracks. Fire genasi hair can resemble threads of fire or sooty smoke.

Genasi

Tracing their ancestry to the genies of the Elemental Planes, each genasi can tap into the power of one of the elements. Air, earth, fire, and water—these are the four pillars of the Material Plane and the four types of genasi. Some genasi are direct descendants of a genie, while others were born to non-genasi parents who lived near a place suffused by a genie’s magic.
A typical genasi has a life span of 120 years.
