Cassiopeia Astara Black was born to Lord Sirius and Lady Marlene Black nee' McKinnon on September 19th, 1979. Sirius and Marlene love their daughter with all their heart and wante her to grow up not having to worry about a dark Lord every moment. They decided to stay neutral and gain allies in the other neutral houses Potter, Bones, Malfoy, Zambini, Greengrass, Davis, and Diggory. They even had allies in other countries with the Delacours.
What many don't know is that the Malfoys only financially helped the dark lord because of threat of their heir Draco's life. The same was with the Zambinis and their heir Blaise. The others were lucky in evading his detection or interest. Susan was raised by her Aunt Amelia after her parents had been murdered. It was because of this that Amelia decided for her family to go neutral. For, she didn't want anything to happen to her niece and heir.
A year later Sirius and Marlene were ecstatic when they met their best friends Lord James and Lily Potter nee' Malfoy's son Hadrian Potter. Lily was Lucius's baby sister and had taken after their mother who had red hair. Sirius and Marlene were made young Hadrian's godparents and they couldn't be happier. Unfortunately, a prophecy had been made and there was only two babies born during that time. Hadrian's parents were murdered because the dark lord known and Voldemort though that the prophecy was about him and Harry. So, Marlene and Sirius raise Hadrian and the young Cassiopeia and Hadrian grow up treating each other as siblings. However, they were actually cousins because Hadrian's paternal grandmother Dorea was born a Black.
One day soon after Cassiopeia and Draco were playing they had been put down for a nap by their family house elves. The two started glowing a gold color and the two families knew that young Draco and Hermione were soul mates. They watched as Draco and Cassiopeia cuddle up to one another in their sleep. Hadrian also know as Harry to his family was sitting up in his crib watchi g the other two. Hadrian, Cassiopeia, and Draco grew up playing together everyday after that. This now leaves us in the present.
