Before you say anything, know that I only made Cecilia because I will be killing three of my characters in the next two weeks. Or rather, they'll be killed. By other characters. But anyway. So Cecilia is just my way of maintaining my place as player-of-the-most-characters.
Anyway!
Cecilia Gerhardt, 27, is a Muggle-born Ravenclaw graduate who became famous as a writer of memoirs when she published the life story of wizarding romance novelist Barbara Gibson. Since then she's written four more successful memoirs and is extremely sought after by the vainest of witches and wizards who believe everyone should know their stories. She is a sweet person with very little common sense, and though she knows a lot she isn't really the smartest woman. She is currently experiencing a pre-mid-life crisis, having realized that she's almost thirty and has no idea what she wants from her own life; she's been too busy wrapped up in everyone else's.
Voila!
