Faries are winged creatures, 5'- to 6' tall. There features are a mix of human and elf, however they also possess glamor and can make themselves look like any humanoid.
Many have powerful fay magic that is unique to them.
While in the Feywild fairies are effectively immortal only showing physical sign of aging up to maturity (about age 100) then never showing signs of aging. Outside of the Feywild their bodies will slowly start showing signs of aging (a process that cannot be reversed). Eventually dying of old age between 1400-1600 years old.
