Prologue

Saint Mungo's was a hospital that was always full of the unexpected considering it was a hospital for witches and wizards. However one day when Lily Evans Potter was in labor and her husband James Charlus Potter was pacing by her side, there was something that happened that no one ever thought was possible...

"James!" "Yes Lily-Flower?" Cue another scream from Lily as her contraptions became more unbearable. "I have to..." she stops and grunts from pain "..tell you the truth about what I'm having..." another grunt comes from the expecting mother "...today. James keep in mind that one night when I stormed out on you. Well that night..." she grunts again and James being over-worried, grabs her hand and starts stroking her hair. "...I met a man at a bar and he bought me some drinks and well.." James looks at his wife and remembers that night and he gets some of his Gryffindor bravery. "Lily-Flower are you telling me that this baby is his?" "No...well not both babies..." He looked at her in shock and faltered with his stroking.

His wife was pregnant with two children and one was his and the other was some stranger's baby. "How is this possible?" James couldn't comprehend the possibility. "James because both times were so close the two sperms took one egg which means..." When she stops to grunt again, James tries to wrap around his mind how his wife is having twins who have different dads. He decides to ask his friends so he conjures his patronus and sends it to Remus, Sirius, Frank and Alice, and Dumbledore.

Dumbledore was the first to show up, followed by Remus and Sirius. Frank left Alice down the hall with their newborn and walked over. When everyone was outside of the room James told them what Lily had told him so far and that she also told him the baby of the other man had a secret and was different then what anyone knew.

They all walked into the room to Lily screaming and grunting in pain because of her contraptions. "Lily-Flower almost all our friends are here and we want to know what is so different about this other baby that your having..." Everyone looked at her waiting and when she could talk and told them they were shocked. "...The father isn't a muggle or even a wizard...he's a..a...a god!" She grunts and screams again. "He's a Greek god...the father is Hades the Greek god of the underworld."

Everyone lapsed into a silence that no one knew how to break until Dumbledore spoke. "That baby can't be raised with you all. I'm sorry but it needs to be trained properly. I believe I know a legacy of Hades that can take the child to its father and be able to contact it when it's time for Hogwarts." James turned to his wife who hesitantly said, "only if we can have the godparents be accepted now." Dumbledore nodded and Lily turned to Remus and Frank. "Remus can you be the godfather of the child please?" "uh sure Lily but are you sure you want me to be the godfather?" "Yes I do. Frank can you go ask Alice if she will be the godmother please?" Frank nodded and walked off to go ask Alice.

Dumbledore sent his patronus to Severus Snape asking him to come to him. James was talking quietly to Sirius about being the godfather of the other child. When Alice came, a nurse came in and checked to see if Lily was ready for birth. The nurse then left to get the doctor and Alice accepted being the godmother once they had filled her in.

The doctor came and shooed everyone but James out of the room. He than asked Lily to push and push. Lily grabbed James' hand and started to scream out profanities that no one would ever expect to come out of her mouth. She kept promising to cut off his family jewels and never allowing him near her again which he didn't believe her. Exactly ten minutes later a girl was born. She had tufts of Lily's red hair and had dark purple eyes with specks of Lily's green in them. James looked at Lily and said "She looks kind of like you. We should name her Arabella." "ok James. if you want." Thirty minutes later a boy was born. He had James everything and Lily's eyes. Lily looked at James and said softly "Lets name him Harry James." "I'll go get everyone then love."

The first one through the door was Sirius followed by Remus, Alice, Frank carrying their newborn, Dumbledore, and then the person they both least expect to see, Severus Snape. "James, Lily the legacy of Hades has arrived to take the child. Which one is it?" James looked at Dumbledore and replied, "The girl is to be taken. She is the daughter of Hades." Everyone looked at the child and gasped. Severus decided to give Lily advice seeing as he still loved her. "Name her Persephone to please her stepmother. She more likely won't kill the child because of it and might care for her more." James looked at Lily and knew exactly what to say.

"Arabella Persephone Evans...it has a nice ring to it." Lily looked at Alice and Remus, "It's time to do the godparents christening." They nodded and placed their hands on Arabella, who was in Lily's arms. Dumbledore stepped up and raised his wand. "With the magic in me I bind Remus John Lupin and Alice Prewett Longbottom to be the godparents of Arabella Persephone Evans if they accept the responsibility now." They both unanimously said yes at the same time and Dumbledore finished the spell. Then Severus stepped up and spoke in his low smooth voice "I'll take Arabella to Hades now and then shall meet with you later Dumbledore." On that note Severus disappeared into the shadows with Arabella.

James looked down at his son and then at Dumbledore before he turned to Sirius and Alice, "Will you both be Harry's godparents too?" They nod and Dumbledore goes through the spell with them. Everyone then left the couple alone with their son for now.

~~To Severus Snape~~

Severus shadow traveled with the little girl to the Underworld to hand her over to Hades. He walked into the throne room and kneeled before the two thrones. Hades and Persephone looked at him and then noticed the little girl in his arms. "Severus do tell me what is that in your arm that you brought here?" He looked at Hades and rose, "Lord this is Arabella Persephone Evans. Her mother can not raise her as a demigod child of yours and ask that you raise her and let her stay her with you. I will come as much as possible but the child is also a witch and so must go to Hogwarts when she reaches the age of eleven. I will take her wherever she needs to go to buy her supplies and if you want I could add my last name to her name. I can pose as her uncle when she goes to Hogwarts if you like Grandfather."

Hades looked at his wife Persephone who sighed and took the child from Severus. She walked out of the room and went to an empty room that she made into a nursery for the girl. She vowed the moment she saw the little demiwitch smile at her that she would raise her to be the daughter she never had...

~~Fifteen months later~~

Even though Arabella didn't live with them, of which made both James and Lily rather sad, they couldn't be happier with the life they have with their son. But it would been happier if it wasn't wartime and that Arabella could spent a couple more days with them at least she was sent off to be trained as a demigod or a demiwitch in Arabella's case. It was Halloween night, they remained inside their cottage, not knowing of what will happen that night not until the door was blasted off. James had looked over Lily, of who was holding Harry in her arms, knowing that they may not live through this night, but he hoped that Lily and Harry would live. James ran to the door and spoke as he did so.

"Lily, take Harry and go! It's him! Go! Run! I'll hold him off!" When James reached the hallway that Voldemort had spoke the killing curse killing him instantly. Lily had went running up the stairs, when she heard the thump of do done falling that she knew what happen and she screamed. Lily had managed to get into the nursery and put chairs and other things in front of the door hoping that it will stop Voldemort. Lily doubted it though, she had barely picked up Harry when the door was blasted open and the things in front of the door were either damaged or were pushed aside from the wand. Lily had looked at Voldemort of who was standing there before putting Harry back in his crib.

"Not Harry, not Harry, please not Harry!"

"Stand aside, you silly girl. . . stand aside now."

"Not Harry, please no, take me, kill me instead—"

"This is my last warning—"

"Not Harry! Please . . . have mercy. . . have mercy. . . . Not Harry! Not Harry!

Please—I'll do anything—"

"Stand aside. Stand aside, girl!"

Lily refused to move and ask for mercy but then green light hit her and she fell to the floor and her last thoughts that Harry might be safe and that Arabella was safe and that she would see Arabella for the first time in fifteen months.

~~In the Underworld~~

Hades stood in the doorway of the nursery that had been made for Arabella, he couldn't help but smile as he watched Persephone play with Arabella. Hades could tell that Persephone had learned to love Arabella as much as Hades learned to love her. Unlike with Persephone, that Arabella was down here all year long, with Arabella that the underworld seem to have become a brighter place to him, even more brighter than when he brought Persephone down here. Persephone had brighter the underworld up for only certain amount of time before she goes back to the surface with her mother. Just as Arabella started to crawl to Persephone that Arabella had stopped suddenly and started crying. Persephone had rushed over to Arabella and picked her up trying to calm down Arabella, Hades knew it will take a while for Arabella to calm down.

Arabella had never really got to know her birth, Hades wished he could have Arabella meet one day, but it was clear that Arabella had sense the death of her birth mother and stepfather. Hades closed his eyes, in many ways he was glad that Arabella was not up there but what worried him was what will happen to the boy that Lily had went the man she was married to. Hades knows he wasn't died, otherwise Hades would have felt it as well as the death of Lily and her husband. Hades had opened his eyes, without saying a word that he left the doorway and left the palace, for he had some work to do. Something he had done before and something he hoped that he would never do again after the last time. But his daughter's sake he had to do, so that she wouldn't scarred from learning of how Lily was killed. He couldn't begin to think of what could have happen if Arabella learns about that night. Hades decided to vow that she wouldn't know until she was older, much older...
