I’ve found a couple, but does anyone know if there is a list of gender neutral elven names collated anywhere for the #dnd Forgotten Realms? Or where there are some language rules I could use as a guide to create mh own? All of the "-une" elven names can be used by any gender.
Lune and Rune are the most popular, but Iune, Lyrune, and Tarune are runners-up.
(Note: Faerunian elves don't normally use D or F or hard-K to begin names, so there're no "Dune" or "Kune" monikers, and "Ph" is used for F.)

Thanks Ed, that’s amazing! A pleasure. Also, all the elven names ending in "ael" can be used by any gender (e.g. Alael, Belrael, Cathael, Eluael, Gelthael). Many half-elves in the Realms seem to bear the "une" and the "ael" names as given names, for reasons best known to their parents.
