There are four types of Genasi – Fire, Water, Earth and Air. The exact origins of the Genasi varies, but the most common is that the Genies of each of those Planes created the Genasi as a means of having servants – but a massive rebellion across the Planes happened at the same exact time – and the Genasi broke free of their masters and became independent and united, creating civilizations in each of the Planes.
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.
Water Genasi: Water genasi descend from marids, aquatic genies from the Elemental Plane of Water. Water genasi are perfectly suited to life underwater and carry the power of the waves inside themselves. Their skin is often shades of blue or green, sometimes a blend of the two. If they have a human skin tone, there is a glistening texture that catches the light, like water droplets or nearly invisible fish scales. Their hair can resemble seaweed, waving as if in a current, or it can even be like water itself.
Earth Genasi: Tracing their ancestry to dao, the genies of the Elemental Plane of Earth, earth genasi inherit dao’s steadfast strength and control over earth. An earth genasi’s skin can be the colors of stone and earth or a human skin tone with glittering sparkles like gem dust. Some earth genasi have lines marking their skin like cracks, either showing glimmering gemlike veins or a dim, yellowish glow. Earth genasi hair can appear carved of stone or crystal or resemble strands of spun metal.
Air Genasi: Air genasi are descended from djinn, the genies of the Elemental Plane of Air. Embodying many of the airy traits of their otherworldly ancestors, air genasi can draw upon their connection to the winds. Air genasi’s skin tones include many shades of blue, along with the full range of human skin tones, with bluish or ashen casts. Sometimes their skin is marked by lines that seem like cracks with bluish-white energy spilling out. An air genasi’s hair might blow in a phantom wind or be made entirely of clouds or vapor.
