Aurenfaie refers both to the people of Aurenen and the language spoken by this group in the Nightrunner series of fantasy novels by Lynn Flewelling.
Seregil learns of a prophecy in which he is to become "father, brother, friend and lover" to Alec, and Alec discovers that Seregil is Aurenfaie, a race of long-lived peoples inhabiting the distant and exotic realm of Aurenen, from which magic originates.
