Summary
The Black siblings; Sirius, Adhara, and Regulus, were a tad bit different than any other children in the Wizarding World. They had somewhat of a happy childhood - living in the Black Family Manor in the South of France with their nanny, and exploring the grounds within the speared iron gates that surrounded the vast property. They spent their free time playing imaginary games and causing mischief wherever they went, especially tiring out tutor after tutor, while their parents worked in London. But everything changed when Sirius was finally of age and went to Hogwarts. It changed when he met four little boys in one of the train compartments in the Hogwarts Express. And it definitely changed that next year, when Adhara and Regulus were of age to go to Hogwarts as well.
Note
The beginning of this fanfiction provides some background of the Black children's lives leading up to Hogwarts, and until Adhara's and Regulus' Sorting Ceremony. From then on, it skips a few years to their teenage years, and the story continues from that "official" starting point.
