Hogwarts (one day and I'm already becoming insane)

my name is Saige Sirius Potter, I'm Harry Potters twin, im the one no one knows about, everyones herd of harry Potter, but not of me... we were raised together after our parents died, then, on our 11th birthday, Hagrid came and told us the truth, my story starts though, on the day we left our muggle lives behind, the day that changed our lives forever...
