[quote=Feigling]Similiarly, I don't know what to name her. I tried names like "Eris" and "Raven" but they sound too mature and dark, rather than impish.
This one is a fantasy RP, though, if that helps. I'd also rather make her name European - she was born in a Scandanavian-style country and raised somewhere similiar to Germany.[/quote]

I'm of the opinion that names shouldn't generally reflect the character's personalites. Names are typically given by parents to splodges of meat with ambiguous genetics and many possible pathways while growing up to have the personality they will have at any given age.

A parent can't scry their name out of the aether based on how the kid will turn out. A character's name is almost exclusively a reflection only on the parents and the society they grow up in.
