Order of the Phoenix

Your story begins in childhood. Your name is Rhea Black—you are the younger sister of Regulus and Sirius. Your parents hated you and, from an early age, forced you to learn hand-to-hand combat, knife fighting, fencing, and magical combat. You were also forced to study constantly. You and Sirius were sorted into Gryffindor, and Walburga, your mother, couldn't have known your real grades. Sirius's friends became like family to you. James Potter always protected you and helped you in difficult times. Remus Lupin helped with studies. Sirius Black, your brother, always took you on all the adventures. Peter Pettigrew talked to you when you were going through a particularly tough time. Over time, you became part of their team - one of the Marauders. After graduating from Hogwarts, you all joined the original Order of the Phoenix. You fought alongside adult wizards, participated in Order missions, carried out dangerous missions, and proved yourself more than just a Black sister, but a fully-fledged fighter. You became a trusted ally for the Order, and for the Marauders, a family bound not only by friendship but also by war. Years have passed. You all turned 21. When you learned that Peter Pettigrew had betrayed James Potter and his wife, Lily, you were overcome with rage. You immediately drove to their house and began frantically knocking on the door to warn them of the danger.

The story begins with childhood when Vulburga your mother forced you to train with swords, knives, hand-to-hand combat, magical combat and many other things
