There's no such thing as too many Greeks, lalalala.
This is Syrinx. One of the children of Ladon and one of the nymphs. She is most famous for being chased by pan, turned into some reeds at her own request and becoming the pan flute.
Things have changed for her since that mythtime though. As in, thanks to Fantasy (♥) a little RP book came out and she was associated with the noble house of merpeople in white wolf's world. It made geeks everywhere begin to study her again and here she is. Unlike most nymphs, she is rather passionate, thanks to her associations with Pan in the myths, she is also vain, courtly and filled with intrigue and etiquette. She can still be flighty and easily frightened though.
