Nagini, with Harry, stepped out of the shadows and walked down the busy streets of Diagon Alley. The snake princess was glad to be back in the world of magic, a place where she grew up. She finally came across Gringotts, the first stop on her mission to ensure they were going to have everything they could possibly have to live at least an average life. She walked past the guards standing outside and walked inside. The main hall was full of goblins lining both sides of the room counting money and going over many documents. Nagini walked down the hall and towards the far end of the room where an old goblin was signing paperwork.

"Excuse me." Nagini said. The goblin looked up from his papers and gazed upon the young snake woman and her child.

"What can Gringotts do for you?" The goblin asked. "I wish to take an inheritance test." Nagini answered.

"Very well. If you will prick your finger and let a drop of blood drop to the parchment, it will allow us to see your inheritance." The goblin replied.

Nagini pricked her finger, allowing a few drops of blood to drip from the wound.

Nagini gasped in surprise, she never knew her parents since they died when she was only a baby. She knew she must have been related to Salazar Slytherin due to her being parselmouth, but never would have thought that her mother was a Pendragon, which made her a descendant of King Arthur. However, the only thing that mattered was being able to take care of her baby boy. She asked the goblin if it was possible to blood adopt the infant she had with her. The goblin looked confused.

"Isn't the baby yours?" He asked.

"This child was abandoned by the Potters because they thought the child was a qquib and would bring great shame upon the Potter name." Nagini replied. "I took him in and I want to blood adopt him into my family."

"The blood adoption ritual will take a day to prepare. Come back tomorrow and we shall have it all set for you my lady." The goblin said bowing to Nagini due to her status as Lady Pendragon.

Nagini nodded as she was then presented with her ladyship rings. She placed them upon her middle finger and after that she took a money pouch and withdrew 300,000 galleons to shop for items for her new child. She thanked the goblin and left the bank and apparated to London, England.

London, England

Queen Elizabeth along with her husband Prince Philip and their children Charles, Edward, Andrew, and Ann were taking a ride in their royal carriage. People waved to the royal family as they waved back with the Windsor wave. Her royal majesty absolutely adored the public and they loved her in return. In the crowd, Nagini stood as her son giggled and waved his hands happily to the queen giggling. Queen Elizabeth noticed and waved back at the child. Deep in the shadows of the alley, Death Eaters were hiding to kill the Queen. They consisted of Bellatrix Lestrange, Antonin Dolohov, Greg Goyle, and Vincent Crabbe. They quickly moved into position as Bellatrix moved to stand in front of the carriage and the coachman stopped the horses.

"Young lady, you need to be more careful; I almost ran you over." The coachman said. "Move out of the way."

Bellatrix didn't move as she reached for her wand. Instantly, Nagini recognized Bellatrix immediately, cast protective charms over Harry and moved to intercept Bellatrix.

"Confringo." Bellatrix cackled, shooting the blasting curse at the carriage.

People screamed as the coachman fell of the carriage and the horses went crazy. The Muggles who tried to help and fight were either tortured or killed much to the horror of the queen. Prince Charles was put under the cruciatus curse by Bellatrix; the other royal children were tortured as well by the other death eaters. Soldiers rushed to protect the family but were blasted back by Fiendfyre and blasting curses. The cruciatus pain ended when Bellatrix was hit with a cutting curse by Nagini.

"Who dare try to challenge us?" Bellatrix asked, in fury.

"My name is of no importance to you, but I have come to stop you from hurting these people and the royal family." Nagini sneered back.

Nagini knew the Windsor family were related to the Pendragon family which made the royal British family her family. She quickly dodged a few curses. Nagini sent spells of her own but she said them in parseltongue, which shocked the death eaters as only the Dark Lord could speak that language. She body binded all three wizards so they would be picked up by the ministry of magic. Bellatrix seizing the opportunity, cast a killing curse at the Queen but was blocked as Nagini summoned a food cart to take the curse. She quickly disarmed and binded Bellatrix. Soldiers and wizards from the ministry arrived and gathered up the death eaters. Bellatrix was hoarded out but not before cackling about how the Dark Lord would return to kill them. Nagini checked up on the royal family.

"Your majesties, are you alright?" She asked them.

"You saved our lives." The Queen smiled. "We can't thank you enough."

"It was nothing really; I was just glad to help." Nagini said.

"May we know the name of our savior?" Charles asked.

"I am Nagini Slytherin and my mother's maiden name is Pendragon." She responded showing them the Pendragon royal family ring. The family was shocked, the royal line of Pendragon that was thought to be extinct due to the death of King Arthur was still alive.

"Who is this?" Prince Andrew asked noticing the baby.

"This is my adopted son, Harry James Potter." Nagini answered. "They abandoned Harry to Lily's magic hating sister because they believed Harry was a squib and didn't want him to shame the Potter name." Nagini said seethingly. "I took him in and I'm going to blood adopt him, but I am worried that the Ministry of Magic will take him away from me as I am also a part of the Slytherin family, which everyone thinks is evil."

"Well I have a solution to your problem, my dear. You can marry one of my children." The queen said, shocking Nagini. "You saved our lives Nagini and we wish to return the favor. Would you like to become part of the Windsor Royal family?"

Nagini went eye wide as she was offered a place in the British Royal Family. Did she want to take this honor? Taking a look at her sleeping baby, she knew this would be the best way to protect him especially with how prejudice the british ministry of magic is. She nodded her head quickly.

"Your royal majesty it would be an honor." Nagini smiled. "But who would I marry?"

"Either my son Charles or Edward." She responded.

Nagini looked at both men and her magic pulled her towards Prince Edward. She saw images of their happy life together and Harry becoming a well respected young man. She smiled as she took the hand of Edward. Nagini and Harry were placed in the royal carriage and the carriage took them on the road back to Buckingham Palace. On the way there, Nagini told the royal family about blood adopting Harry. The blood adoption ritual she wanted wasn't a normal blood adoption. This was the Alpha Blood adoption; it would remove all blood connection that Harry had to James and Lily and replace it with the blood of Nagini and Edward. The prince had no objections. Arriving at Buckingham Palace, Nagini was given her own room with a royal crib for Harry soon to be crown prince Harry Pendragon. The following day Prince Edward and his soon to be wife Nagini were dressed in their regal royal clothing, while Harry was in a royal onesie. Nagini took out a portkey and they were transported to Gringotts bank.

"Lady Pendragon, I see you brought company." The goblin said.

"This is my fiancé - Prince Edward, Earl of Wessex." Nagini replied.

The goblin bowed to her and Prince Edward. Edward hadn't met goblins before but he was told that they handle finances far better than any muggle bank. Perhaps he could ask the goblins to secure and protect the royal family fortune in the future.

"My wife and I are here for the blood adoption of our new son" Edward said.

"Follow me." The goblin said taking them into the ritual chamber.

When they arrived at the chamber, they were required to cut their palms to allow blood to pour into the bowl. Their blood filled the bowl and was poured into a baby bottle. It was magically disguised as baby milk as Nagini fed the bottle to her son. Harry drank it down fast as he was very hungry. After the bottle was empty, Harry let out a little burp and fell asleep. Harry's hair turned from brown to raven black like Nagini's. His body structure changed to that of Prince Edward and had Nagini's eyes. Every detail and feature of the Potter and Evans family was now gone for good. The goblin gently pricked the baby's finger letting blood drop from his finger onto the parchment. The goblin smiled as he handed the parchment to the royal couple.

"The ritual was a success take a look." The goblin commentated.

Edward took the parchment as he and his wife took a look at the parchment containing their sons new lineage:

The Royal couple were smiling as the ritual was a success. Prince Edward held his son in his arms as he was finally a father. When Nagini looked over her son's results, a part of the information confused her.

"Honored Goblin, why does my son's magical status say reincarnation?" Nagini asked.

"Do you remember that rune on your son's forehead?" The goblin asked.

"What about it?" Edward asked.

"That rune was the same rune the great dragon carved into Arthur's skin after he died. The magic in your son's rune is the very same magic that was given to Arthur." The goblin explained.

"Are you saying that my son is the magical heir of Arthur?" The prince chuckled.

"Harry isn't the heir of King Arthur, he IS King Arthur." The goblin replied.

The room went silent as Nagini and her husband were speechless that their child was the reincarnation of King Arthur himself. Edward asked that this was to kept as a secret until Harry was at least eleven years old. The goblin nodded as Edward also asked if their King Ragnok would be interested in meeting with his mother to discuss having the goblins secure and protect the royal family's vast fortune. The goblin nodded shockingly, as he said he would let their king know immediately.

"Thank you honored Goblin. Come to the Buckingham Palace in two days." Edward said.

"You are too gracious, your majesty." The goblin said.

"Think nothing of it. Thank you for all you've done for us" Edward said.

"You're most welcome, your majesty." The goblin said.

Nagini smiled at the goblin as she and her husband left the bank. When they exited the bank, Edward smiled at his wife as they shared a kiss.

"I believe we also have a royal wedding to prepare for." Edward smiled.

"I believe we do." Nagini smiled as she apparated with her husband to be and new son back to Buckingham Palace. -
