xXx Evans Residence, Cokeworth, England xXx
xXx February 1st, 1960 xXx

Unbeknownst to the residents of the house on a little sleepy drive two extremely powerful magical entities had just arrived outside their residence.

"Are you sure this is for the best My Lord? I mean the residents of this house don't have any magic in them at all. Usually we leave our children with those of magical lineage," a woman with green eyes that were so brilliant they practically glowed with power and hair like an inferno, asked of the man whom she was standing to the right of.

"Yes my dear, while this family does not have any magic, one of their ancestors saved my life during a war some centuries ago. I am merely returning the favor by gifting them with something that may bring them incredible happiness." The man said.

"But to give them our precious Lilium… I just don't know…" the woman continued.

"Trust me; she will have a happy life. And worst case scenario, we can come and retrieve her at a later date." The man answered, he then took their daughter from his wife.

"Promise me one thing. Ensure that she will retain her name." The woman asked.

"I will do what I can." The man said, he already knew these humans had named their daughter Lily, so it wasn't that much of a problem. That was part of the reason he had decided to go ahead with his plan at this time. Floating up to the nursery window, and phasing himself and his daughter into the room, he looked around the room, and smiled when he saw the young little girl who he would be replacing. Going over to the child he used magic to levitate that child out of the bed, while gingerly replacing his daughter into the bed. "Fare thee well Lilium, and safe journeys."

He then took the real Lily Evans in his arms and phased the two of them out of the room and back down to his wife. "Let us be away my dear."

"Yes. It would not do for the mortals to see us, now would it?" the woman said. And with that the two otherworldly beings, plus the human child vanished from the world of men.

xXx Godric's Hollow, England xXx
xXx October 31st, 1981 xXx

Unbeknownst to the Wizarding World as a whole, the Fidelius Charm is only effective against those whose magic originates in the physical world. Thus the Fidelius Charm has little to no effect against beings such as Dementors. However there is another lesser known order of being who remains unaffected by the Fidelius Charm. And it is a member of that order of being who in the form of a centipede currently sat in the Potter family's nursery keeping an eye on the young Heir to the Potter family.

The long number of days sitting here hour on hour with nothing all that interesting happening were broken when there was shouting coming from out in the hall and then Princess Lilium ran into the room. Oh sure, she didn't know she was a Princess due to her parents never having an opportunity to tell her, but that didn't change things as far as her people were concerned.

The shouting continued as Princess Lilium frantically performed some sort of magic on the crib, while etching runes into her hand and lightly onto the forehead of the Little Sir. The entity, whose name is Nes, instantly, knew what those runes signified and thought 'Oh bloody hell, she means to sacrifice herself; Queen Oona is going to be pissed.'

Almost in sync with the last of the spells that Lilium was casting had finished, the door to the Nursery burst open and in walked a man who oozed dark magic. So much so that Nes was thinking 'What the hell did he do to himself? He doesn't feel whole… Oh… oh yuck… yuck, yuck, yuck. How could anyone do that to themselves?' was all she could think.

Meanwhile the man raised his wand at Lilium and said "Step aside girl. All I want is the boy. Step aside and you will come to no harm."

Lilium, ever the stubborn child raised her arms defensively and said "Not Harry, anything but Harry."

The man in an exasperated tone said "I will not ask again, step aside and you will come to no harm."

Lilium in stubborn protest began to raise her wand while still saying "Not Harry, please not Harry!"

The man just said "Avada Kedavra!" and a bright green light issued from his wand.

Nes thought 'Shit!' and watched in horror as the man raised his wand at the Little Sir.

"Avada Kedavra!" the man said, and the green light of the killing curse issued forth from the wand. However as soon as it touched the young boy, the rune on his forehead glowed bright red, coursing with magic. The bright green of the Killing Curse scrunched up in a ball of light and then shot straight back at the man, who as soon as he saw what was happening said "Aw shi…" he didn't get enough chance to finish what he was going to say as the curse hit him.

Now to most eyes what happened next would make you assume the man was dead. But to the eyes of Nes, who could see the magic in the area as it happened, nothing could be further from the truth. What Nes saw as the Killing Curse hit the man, was about three dozen rune tracings on the man's body all simultaneously light up, which resulted in the man's body self-destructing taking everything but his wand with him. Additionally she saw a magical tracery connecting the man's soul to whatever accursed objects he may have made allowing him to retain an existence.

What truly horrified her however was that a small portion of the man's soul split off from the main body and burrowed into the scar on the Little Sir's forehead.

As soon as she was certain that the rest of the man's soul had vacated the property she immediately transformed into a form that closely resembled human, though the horse ears and tail ruined the appearance rather spectacularly. In this form she appeared to be little more than a child of 5 or so. She quickly walked over to young Harry's crib and performed a few diagnostic charms, something that was ridiculously easy for someone of her nature.

"Damnit, he has a-a-a whatever the hell that is; in his head. Otherwise though he appears to be fine, that's good. Hey there Harry!" she said.

"Nes! Nes! U help Mum?" the one year old asked in the way that only a one year old could.

Nes smiled sorrowfully and said "Sorry Harry, but there's nothing I can do. But don't you worry. We will look after you, you are family after all."

Suddenly there was a loud popping sound and a loud voice asked "James? Lily?"

Sighing that she would have to hide again she transformed into a baby blanket and floated herself into Harry's crib. Harry, bless his heart immediately grabbed onto her. Just in time too as a rather large man made his way into the room.

xXx #4 Privet Drive xXx
xXx November 1st, 1981, 3:00 a.m. xXx

The night had been long and stressful for Nes. Harry fortunately had slept through most of it. As soon as they had arrived at Privet Drive, Nes had instantly become aware of the wards that were emplaced around the residence. How could she not? They utilized blood, specifically Princess Lilium's blood.

What Nes couldn't understand was how these wards were supposed to work. The runes used in constructing them implied that they were supposed to offer some sort of protection to Harry simply by virtue of him living in the same house as someone who share a blood relationship with his mother. While that was a nice theory, it didn't work because Petunia Dursley didn't share a blood relationship with Harry's mother.

To make matters worse, Nes had passively scanned the minds of all three of the adults that had shown up to leave Harry at his 'Aunt' Petunia's; and while she couldn't get past that old man's shields without alerting him to the attempt, the woman, Minerva McGonagall was an easier read. And Nes happened to agree with Mrs. McGonagall, Harry would be far better off with someone else rather than being left with Petunia Dursley. Nes had heard the rumors from her friends, this Petunia actually despised magic. And that says nothing about her husband. Leaving Harry here would be little better than a death sentence.

What made matters worse, is that Nes could sense the wandless tracking charm that the old man had placed on Harry. Not on his clothes, not on his blanket. No, he placed it directly on Harry himself. And the Charm was quite powerful; powerful enough that it would only need to be re-applied once a year.

'Oh well, it's not like Lady Oona can't get rid of that.' Nes thought to herself, still in the form of Harry's binky.

And they just left, left him on a doorstep in the middle of the night on the first of November. It's got to be near freezing out here. 'None of them even bothered to apply a warming charm!' Nes thought to herself furiously as she allowed her magic to actively keep the two of them warm. This was going to be a long, long night, she could just tell.

xXx #4 Privet Drive xXx
xXx November 1st, 1981, 7:00 a.m. xXx

Nes was rudely awoken after getting only four hours sleep by an ear shattering scream which had the ancillary effect of waking Harry up and causing him enough displeasure that he started crying himself. Using her currently invisible eyes to give Petunia Dursley a death glare, Nes was quite surprised when the woman checked herself and glanced around at the other houses in the neighborhood. Then seeing that no one was looking she nodded to herself, and picked up Harry's baby basked and brought him into the house.

She took the letter that was left with Harry, and tossed it aside. She then walked over to the cupboard under the stairs, opened the door and placed Harry, basket and all, inside the cupboard and closed it, going about her business.

Sighing inwardly Nes levitated herself off of Harry who suddenly got a bit clingy. She let him hold onto her as she transformed back into her humanoid shape, making the bit he was holding into her hand. "Harry, I need to go talk to your Grandmother. I can't leave you in these people's custody like this. I don't know how long I will be gone as time flows differently where I am going, but I will be back. I promise."

"U come bak. U pomise." Harry mimed.

"Yes, I promise. Now I have to go." And with that Nes vanished from right in front of him causing Harry to start crying once again.
