Genasi {Void}

Many theorized how void genasi came to be, but most guesses include them as corrupted form of air elementals or perhaps the results of certain kinds of magical experiments or rituals. The void genasi are generally humanoid, but have an eldritch, otherwordly aspect about them, such as out of place abberations that frequently appear on their body, extra appendages, limbs, eyes, wispy smoke or cloud-like hair, skin that's ice cold to touch or palettes that shift from dark blue and purple to shimmering starry textures, giving them a look of as if the night sky was condensed into the form of a person.
