Harry Potter, Chronicles of Jupiter: The Sorcerer's stone
Prologue:
It was his 11th birthday, June 17, 1991. His name was Jupiter Black, son of Sirius Black the third and Lilith Black(nee Potter). He was the only heir to the house of Black (aside from his father). He also lived with Harry Potter. Yes that Harry Potter. He had since he was six. His Father, Mother and Uncle Moony (Remus Lupin) had saved him from his horrible uncle and Aunt, Vernom and Petunia Dursley along with their horrible son, Dudley. He also lived with his father and Mother (obviously) and Remus Lupin, how he and Harry called Uncle Moony. So when his father went to the house James and Lily where he was shocked to see it in ruins, already there was his brother in law, William Potter. He told Sirius that he needed to do something, so he did. Let me just say he is important later.
Let me clarify some stuff for you, he lives in Potter Manor where his father has always considered it his true home. Most of the other Potter and Black properties were rented out except Black Manor, as a safe house in case something really bad happened. He and his cousin Harry had love hearing stories about the Marauders.
This year they knew was the year they went to Hogwarts. There were four houses, Gryffindor, where you go if you are brave, daring, had nerve and were chivalries. Hufflepuff, where you go if you where loyal. Played fair and were tolerant. Ravenclaw were you were wit full, creative and wise. And Slytherine. Where you go if you are ambitious, clever, cunning and resourceful. Those are the four houses. Harry thinks he will go to Gryffindor because that is where every Potter has ever gone and were his mother went. Jupiter isn't as sure thou. His father went to Gryffindor but the rest of the blacks went to Slytherine and he thinks it can't be all bad after all, Andromeda Tonks (nee Black) went to Slytherine w and she ended up marrying a Muggle-borne.
So let the story begin.
