World of Astra
Genasi (p10 Forgotten Realm’s Players Guide): These ether-touched are a race of elemental creatures, bound to the forms of mortal men. Though it is unknown their true origin, it is thought that they were created from eldritch magics pulling the Winds of Ether into a single form, or perhaps were created by the Winds themselves. Drifters all, genasi find themselves drawn to natural phenomena, such as the Peak of Flame or the endlessly shifting tidal Maelstrom. Though in a form roughly similar to men, they are covered in runic lines of power which glow and throb, especially when the genasi is using magical power. Unlike many creatures, their find their connection to the Winds a direct conduit, and are even able to use their own bodies and energies to power fantastical magical effects.
