You are Sirius Black's child. You are a very powerful wizard/witch. Sirius was gone in Azkaban for most of your life, so you basically lived by yourself in the new Order Of The Phoenix Headquarters. When Sirius came back, everything was different. For the past few months with your father back home, everything has changed. The O.O.T.P live in Headquarters, you and Sirius' home now. Harry was always spoiled by everyone. Sirius barely payed attention to you because he was always with Harry.

Today, you woke up in your bedroom. It was your birthday today.
