Name: Mine? Rebecca.
Character: Annie Kavanagh, a multiverse OC. She does have two OUaT verses, though, and I am entirely familiar with Once.
Child or Adult: Child, please.
Backstory: Annie is the youngest child of Sharon and Harold Kavanagh. Sharon is a middle school English teacher, Harold is an attorney. She has two older brothers, Ethan and Matthew. She has taken dance lessons for a year or two (depending on whether you want her to be four or five). Overall, she comes from a happy, stable, upper middle class home and is a cheerful, friendly, outgoing girl.
Thank you for your consideration. If you cannot accept Annie because she isn’t fandom specific, I completely understand.
