My name is Chrystashia. I have a last name, it is that most people jump to conclusions when I tell them my last name. I am going on a limb and trusting you. My last name is Black.
Sirius Black is my father, but he is NOT a murderer. He is NOT a Death eater. He has never helped Tom Marvolo Riddle, A.K.A Voldemort. Our family has but my dad and I never have nor will serve the old, snake faced, freak.
When my father was sent to Azkaban, I was sent to one of my father's best friend, Remus Jasper Lupin. Lupin was called Mooney by my father and his friend, my godfather James Potter, and his fake friend, Peter Pettigrew.
James was called Prongs, Peter was Wormtail, and my dad was Padfoot. You see, Lupin is a werewolf. My father and his friends (fake or not) had drank a potion to make them animegi (plural of animegis).
My dad was a big, black (yes, I see the irony) dog, hence the name Padfoot. James was a deer. Peter was a mouse. The reason the three became animegi was so that they could be with their friend while he was a werewolf. Dad and Prongs were large animals so that if Mooney was to attack them, they could defend themselves. Peter was small so that he could get past the Whomping Willow branches and touch a knot on the tree that would petrify the tree long enough to get Mooney, Dad, and Prongs to a hole at the base of the tree that leads to a place people call the Shrieking Shack.
It isn't haunted, it was just Mooney screaming in pain as he turned into a werewolf. Mooney taught me how to fly on a broomstick. For my birthday, he took me to meet some others like us. Mooney and I live alone in the Shrieking Shack. I had learned how to make the potion that prevents him from turning as much as possible. The family we went to see was a big one.
