When I read The Silmarillion, Idril was one of my favorite characters. I don't quite remember why I needed a new name, but after going through about five non-sticky names I chose that for my first name. and then for a surname, Falas means shore, and tári is queen.
It was about two years ago, but Idril Falastári has stood the test of time for me.

I keep it because it feels like me.
