Aelius Potter is the younger sister of James Potter. While going through her journey at Hogwarts she meets many friends while making plenty of enemies. She is different from her brother in many ways but the only ones who see it are Remus Lupin and Regulus Black. Once she joins the Order however, she really shows James how different she is from him. Stepping up to become a spy and losing the love of her life. How will she handle everything life at Hogwarts has to offer and more importantly how will she handle Regulus Black. ------ Aelius is an OC, all other characters and setting belong to J.K. Rowling and the Harry Potter franchise. This is just a fun little fanfic I wanted to write. I hope you all enjoy following Aelius' story. This story will hold depictions of sex, strong language, death, grief, and mental distress.
