Light Elf (5e Subrace)
From D&D Wiki
Hailing from the Elemental Plane of Air, light elves live high in the sky on solidified clouds that are surrounded by endless open air. Light elves are fun, loving, and charismatic. They tend make friends without trying. Though they love the Plane of Air and open skies, light elves do relocate and settle in other planes.
