The Forgotten Potter

On the night of July 31, 1980, not one, but two Potter's were born. Julianna Lily Potter and Harry James Potter were their parents pride and joy. With the war looming over the family, along with two different Prophecies about their children, James and Lily went into hiding, trusting their best friend, Peter Pettigrew to be their Secret Keeper.

On October 31, 1981, James, Lily and Julianna Potter met their demise at the hands of Lord Voldemort. At least, that's what everyone thinks. Lord Voldemort was accompanied by Alecto Carrow on the fateful night. After watching the Dark Lord be vanquished by Harry Potter, she quickly grabbed Julianna and Disapparated, leaving behind the lifeless body of a different baby.

Alecto raised Julianna, changing her name to Kali Carrow, cutting off all ties to the Potters. Alecto did not enroll Julianna in Hogwarts, for she feared that Dumbledore would find out her secret.

In Harry Potter's first year in Hogwarts, he finds the Mirror of Erised, he sees his family, including a dark haired girl that Harry vaguely recognized. She walked across the Mirror, smiled at him, and disappeared.

In his fourth year, Voldemort is resurrected by Julianna herself, although her identity is still unknown to him. While staying at Grimmauld Place, Harry finds out that he had a twin, Julianna Lily Potter. But as far as Remus and Sirius knew, she was dead.

At The Battle of the Department of Mysteries, Julianna makes herself known as the Forgotten Potter. Little did she know her own Prophecy lied mere meters away from her.

Julianna had to die for Harry to win the war.
