I do not own Harry Potter or Charmed. This is just a bit of fun. Reviews are welcome.

Prologue

October 30th, 1981 Godric's Hollow

Lily and James Potter were sitting together in their study/library discussing there current situation. Both were concerned about the welfare of their only child and son Harry who was asleep upstairs. James expressed his doubts about choosing Wormtail for a secret keeper and wondered aloud if it was too late to switch. Lily was deep in thought when suddenly she shot to her feet.

"I've got it!" she exclaimed keeping her voice down at the last minute. "We can call for Harry's guardian!" James looked at her like she had grown two extra heads.

"Call for his what?" Lily rolled her eyes.

"Every witch or wizard has a magical guardian James. We can call for Harry's to help protect him and keep an eye on him in case..." She didn't finish the sentence and didn't have to.

James expression grew determined and nodded in agreement. The two, not wanting to waste any time, walked quickly to Harry's room. Lily gently lifted her sleeping baby boy and nodded to James. After taking a deep breath he said aloud the words his wife told him not 5 minutes ago. The Potters waited in silent anticipation for anything to happen. Even so both were surprised when a woman at least 10 years older appeared in a swirl of blue lights with a baby a few months older then Harry in her arms.

"Where am I? Who are you?" The woman backed slowly away turning so she shielded the baby with her body.

"You're in Godric's Hollow in Wales," James said quickly. "Im James Potter and this is my wife Lily."

"And this little guy is our son Harry," Lily rubbed the baby's back gently. The woman relaxed.

"I'm Piper. Why are we here?" She wanted to know.

"We summoned Harry's guardian," Lily explained. "Is that you?" Piper shook her head wearily.

"No, that would be my daughter Serena," she indicated the baby on her hip. Both Potters gaped at the woman shocked.

"But how can she help Harry still being a baby herself? Voldemort could attack any day." James sputtered. Piper smiling in understanding.

"She's a remarkable little girl despite her age. A magical prodigy." Piper walked over to the crib and the two looked at the sleeping baby. Piper looked at her daughter. "Rena this is Harry Potter your first charge. Remember how Daddy and I told you about charges."

"Uh-huh," Rena said the serious expression amusing on one so young. She turned from her mom and looked at the little boy again. Reaching down she touched his back and whispered something no one could hear. Her mother smiled at the brief golden light and explained that she was forming a bond with him as all whitelighters do. It was to enable them to hear or know when their charge was in danger. None of the sdults saw the light go from gold to white.

"Thank you," James said hoarsely. "I-'

"You don't have to explain, I would have done the same." Piper interrupted.. "Have you prepared for the inevitable?"

"No," sighed Lily. "We've been procrastinating." Piper nodded in understanding.

"It's never to late to start," She bid the Potters good-bye and the two disappeared in a swirl of blue lights. Before she left she whispered "Prepare the trunk."

Taking the older woman's words to heart Lily and James got to work on preserving memories for their son. While James was dragging a trunk out of the attic Lily made a fire call to Alice Longbottom, her best friend. Both their boys were possible candidates for a prophecy their former Headmaster heard. One that would cause the chosen one to be number one on Voldemorts hit list. Alice appreciated both suggestions and she and her husband Frank ended up summoning Piper and Serena again as well as preparing a trunk of their own.

The Potters were busy preparing the trunk. As the charms expert Lily was in charge of building the trunk. She made it seven compartments. All the compartments were for storage, each one holding something different. One compartment held books, another potions ingredients and supplies. James placed numerous family and personal heirlooms in one compartment, while Lily placed papers, an animated portrait of a group of their friends (all updated), as well as her and James' personal journals. The rest of the Potter Heirlooms and furniture would be deposited in the Potter family vault. Their will was done and a copy was in the trunk as well as both Potters personal journals.

Lily's last bit of charm work was to charm it to disappear if she and James were to die and transport to Harry's whitelighter for safe keeping. Both had written letters for both their son and Serena. James had a visit on Halloween morning with the Head Manager at Gringotts with explicit instructions for the managing of his estate vaults should something happen to he and Lily. He deposited the trunk full of furniture and valuables from the house and updated the security on the family vault to blood and magic wards. Only someone with Potter blood and magic could gain access. Sirius Black had met James at the bank and once he had learned of what took place the night before he suggested he and Harry perform a blood adoption ceremony. James liked the idea a lot, it would untangle a lot of red tape if Harry was a blood relation to Sirius. Guardianship would go smother if...

Lily and Harry flooed in and Ragnok performed the ceremony himself and filed copies of all in the Potter family vault and the personal vault of Sirius Black. The Potters left Sirius at Gringotts to do a bit of shopping, incognito of course, and purchased numerous things to add to their sons trunk. Harry was blissfully unaware as his father had made a beautiful cloak with the Potter and Black Crest as a present for his maturity. He also purchased a cloak pin and pocket-watch for that special birthday. He picked up a few Quidditch books and paraphanalia and went to rejoin Harry and Lily. Lily, meanwhile, had gone through the cauldron shop, apothecary, and bookstore buying all that she could. She would put the potion ingredients in stasis in the trunk potion lab. All day she could have sworn she heard a ticking clock and it inspired her to buy a pensieve a fill it for Harry to view later on.

The Potters arrived home at 4 p.m., while Harry played with a new toy his parents filled the pensieve with their own memories of childhood, their school days, and after. They worked in the trunk for the rest of the evening. As Lily was taking Harry upstairs Voldemort entered the wards.
