Happy late Halloween everyone, Imouto here. Welcome to my first story here on fanfiction. This is going to be a massive story with several crossovers, a few major, most minor. This will start off in an au harry potter world with a fem harry named Helena and her twin sister Raven(as well as other genderbent and crossover characters). They will be keeping the Evans name for reasons that will be obvious once you get through the prologue. Several aspects of this story were inspired by others and I will give them all credit when the ideas I got from them show up in the story. Many characters will also be severley occ, some for obvious reasons and others because it fits, like I said this is an AU so do not expect a lot of canon personalities or events. The Prologue will be it's own ark called beginnings since the full thing is over sixty thousand words long and it will contain a lot of flashbacks, exposition, character development and personality setting so be warned that it will take a while to get to the actual story. This part will cover the changes I have made to Lily's character as well as her … conception of the twins. This is one of the shorter parts of the prologue but it is still decently long.

I don't really have a good summary for this story so I will just list a bunch of tags and add some warnings for triggers after it. The harem list for the first story and side pairings will be at the bottom.

Tags: Fem Harry, Half Demon Evans twins, Vampire Lily, Dark but not evil Evans family(Think Addams family but much less masochistic and slightly more sadistic), Mass lesbian Harem, Twincest, AU travel(mostly in sequel), multiverse travel(mostly in sequel), Crossover with various movies shows games animes books etc…(crossovers with fan-made au's will be marked at the bottom when they appear), Evil dumbles, GWL Fem Nev and more.

First story crossovers: DC(mainly raven from teen titans, and a few other characters), Hellsing and Hellsing Ultimate(mostly Sera's and Integra), more to be listed when they appear. And this is all with in the first(yes I said first) au hp-verse. Other big crossovers will be dealt with in sequels. This one is mostly about the Harry potter world.

WARNING!: This chapter will contain mentions of rape(but no rape scene) so be warned, I will mark when it happens so that you may skip it if you need to.

Begin

Lily smiled as she watched her 14 month old daughters sleep in their bed. While she may be in hiding from both an insane war monger and a manipulative bastard, she was happy. And while she knew this wasn't this best environment to raise two children, she was well aware that it was better than some could ever hope for in their situation.

As she watched the shadows wrap around them like a second blanket, she thought back to how she had received her beautiful girls.

If only it had been as beautiful as them.

(Flashback(with flashbacks in flashbacks))

Lily Evans was annoyed. For some reason Dumbledore thought that she would want his help hiding from Voldemort. Not only that but he thought it would be a good idea for her to hide out with that Bastard James Potter. Oh she could see how well that would work out. James would be lucky to survive the first week if he kept up his usual attitude with her.

Some how the idiot had got it in his head that they were destined for each other and that she could never be with any one other than him. It was for this reason that he did his best to ruin her friendship with Snape. She had been terrified when she thought he succeeded in their sixth year, but luckily Snape came running to her just before curfew that night to apologize and explain himself.

(Flashback in flashbacks)

Quite sobbing could be heard coming from the Ravenclaw 6th year girls dorm room. Lily Evans was distraught. Her best friend had gotten into another fight with that insufferable prat James, but when she had tried to help him he had shouted at her that he didn't need help from a filthy mudblood. She had run away to quickly to notice the look of horror that had appeared on his face after he said it but by the time he fully realized what had happened she was already gone.

He had been searching for her for the past two hours and was starting to grow frantic when he was suddenly pulled aside by one of the four people he really didn't want to deal with at the moment.

"What do you want Black? In case you can't tell I have more important things to do than deal with your pathetic pranks." Severus snarled at one of his most frequent tormentors.

Surprisingly, instead of snapping at him, Sirius seemed to look apologetic. He opened his mouth as if to say something, but the words appeared to get caught in his throat so he closed it before trying again. He repeated this a few times before sighing in frustration and pulling out a large piece of blank parchment.

Severus was about to snap at him for wasting his time when Sirius pulled out his wand. He immediately went on the defensive expecting some sort of attack, only to watch in confusion as he pointed it at the parchment and say "I solemnly swear that I am up to no good."

Suddenly several lines appeared on the parchment as it unfolded itself. Soon it was clear to see that the lines were making a map of Hogwarts. He soon saw small foot prints appearing all over the map with names over them. Severus only had a moment to realize what this was and what it meant before Sirius pointed at something on it. Looking were he was pointing he saw Lily's name in the Ravenclaw tower(1).

Severus was elated to find out where Lily was when he suddenly remembered who it was that was giving him this information and what he had said before showing him this. If he was up to no good, then that probably meant this was another prank.

Just as he was about to shout at him for messing with him Sirius said "Look I know you have no reason to trust me, and we both know that normally I wouldn't care at all about what you do after wards, but we crossed a line and made you cross a line. And while James seems to be ecstatic that you probably no longer have a good relationship with Lily I know how much she means to you. I know we don't get along, hell we fight more often than not. But I don't actually hate you despite what you may believe. Our pranks aren't supposed to actually hurt people and the fact that we might have caused irreparable damage to your relationship with Lily doesn't sit right with me. So go and try to fix this mess we have made. I promise that at least me and Remus will apologize tomorrow but I can't say the same for James and Peter. Just … go fix this royal fuck up before it's to late."

Severus couldn't believe what he was hearing at first but soon realized that he was right. While the marauders were insufferable their pranks never caused real harm, and that the only one whoever actually targeted him was James. He nodded to Sirius in gratitude before running to the Ravenclaw dorms.

He arrived at the door and after answering a pointless riddle he ran up the stairs to the girls dorm, not bothering to question why the stairs didn't reject him before he found himself in front of her dorm suddenly at a lose at what he should do. He was still trying to figure that out when he heard her crying. Realizing that he had to focus, he steeled himself before knocking on the door. He heard a quick gasp before hearing a quiet "Who is it?" from the other side. Hearing her sound so weak made him feel even more guilty than before.

Quickly before he could lose his nerve he responded. "It's me, Severus". He waited for her to respond. He didn't hear anything for a moment before a small sound of footsteps could be heard. She opened the door and before he could say anything she slapped him. After regaining his balance Severus looked at her to see her face stained with tears while she looked to be a mix of enraged, sad, and exhausted. They stared at each other for a moment before she asked "Why?".

He immediately said "Lily, I am so sorry. I was upset and I wasn't thinking and I didn't know what I was saying. I am so sorry. You should know that I would never want to hurt you. It's just that James makes me so mad and I was just so mad and humiliated, I didn't want you seeing me like that and I just shouted. I am so sorry, please give me a second chance. Please don't hate me. I know I have been a real arse lately but if you give me a chance I can explain. Please Lily."

Lily looked at him for a while, seemingly judging his sincerity, before nodding.

(End flashback within flashback)

After literally begging at her feet for forgiveness he explained that he had found hate potions laced in his food a month ago and that they were keyed to her. After discovering this he realized that someone was trying to split them apart for some reason so he had to act like he was taking the potion. It hurt every time he degraded her, and he knew that when he had let his own rage at James take control long enough for him to truly hurt Lily that he may have crossed a line that he would never be able to return from. That likely would have destroyed him if Lily hadn't been understanding enough to forgive him. Lily was the closest thing he had to real family and he didn't want to lose her.

Yes Snape saw Lily as his sister. Despite popular opinion Snape did not have a crush on Lily, nor did he have any fantasy's of her falling madly in love with him. Though to be fair Snape was the only one who knew why Lily never accepted date request's from the many boys that had tried to court her. Lily had no interest in boys, at least in the romantic sense, because she was a lesbian. Of course she wasn't an idiot, she deserved her title as smartest witch of her age. She knew that the wizarding world was centuries behind the muggle world when it came to acceptance, and with the muggle world barley tolerating homosexuals while she went to Hogwarts, she had no illusions that she would be accepted there. Of course she had still crushed on a several of her school mates, and a few even seemed to return her affection, though usually they would move on and it would never go any where. Though her best friend Alice had actually been with her for a time and likely would still be with her if her new step mother wasn't such a traditionalist. Alice, unlike Lily, was bisexual and had fallen for both her and Frank Longbottom. She had actually been with Frank before he figured out she had feelings for Lily as well and made her pursue them. For a pureblood he was surprisingly accepting and he had no problems sharing since unlike in the muggle world, polygamy was still practiced in the wizarding world. Well at least by purebloods. It wasn't until Augustus found out that they were forced apart. She still occasionally saw them even after the war had started, but about a week ago they had gone into hiding under Dumbledores advice despite all of her protest's.

(Yay more flashbacks)

"But Alice, your child is still due several months from now. You know you wont be able to care for them as well as you can at the manor. And why do you even have to leave the manor in the first place, if you put the fidelius around the manor itself and not the entire property than it wont even mess with the other wards. It will be much safer than going to an unprotected cabin in the mountains with out access to help for miles around. I don't want to lose you if something goes wrong."

Alice looked at her with an apologetic look before saying "I know how you feel about this Lily. To be honest I am scared to, but this really the safest option we have right now. If we were to go with your suggestion the we would be even more likely to be attacked since the property line would still be known and they would be able find us still. There are ways around the fidelius if you at least know the general area, you know that. I don't want take any chances with my daughter on the way."

Lily sighed in defeat before saying "At least let me come with you, the thought of losing you, it just destroys me. Please let me come."

"I'm sorry Lily but with you being my secret keeper you know you cant stay with us. You know how much I would love for you to be there to help me raise our child. Hopefully this war will end soon and you will get to meet your goddaughter soon."

Lily just sighed in resignation before grabbing Alice and pulling her into a strong embrace. "Just please stay safe, I don't want to lose you or my goddaughter." she closed her eyes for a moment before smiling slightly and saying "Franks nice to I suppose."

Alice laughed a little at that before reassuring Lily. "You know I will be as safe as possible, after all I still have you, Frank, and our daughter to live for. I will make sure you get to see our child and help raise her."

There was knock on the doorway. They looked over to see Frank looking at them apologetically. "I hate to break this up, but it's time".

Lily sighed before she kissed Alice goodbye."You better come back to me safe and sound." She then turned to Frank and glared at him "And if anything happens to her than after I destroy what ever hurt her I will show you my own special hell, is that clear?!"

Frank nodded and said "If anything were to happen then I would be the first to give you your knife and wand. Don't worry we'll be back."

Lily merely nodded while tears rose up in her eyes. She wanted to believe them. She wanted to believe that everything would be alright, and that she would get to see and raise her goddaughter along side them but she couldn't stop crying. Because as much as she wanted to believe them, she couldn't shake the felling that this would be the last time she saw them.

(Flashback flashback over)

After they left Dumbledore had started trying to convince her to follow their example with James and she had repeatedly told him no. Now here he was trying to convince her that it was a good idea to go into hiding with one of the few people she could say she hated with out reservation. And the whole time James was leering at her like she was some kind of prize that he was about to win. After another hour of him trying to convince her that he knew best Lily stormed out after telling them in no uncertain terms what she thought of the old bastard and his infallible wisdom.

Two weeks later is when the nightmare started.

Lily was listening to wizarding radio, waiting for any reports about the attacks, when there was suddenly a large explosion against her wards. Lily ran to her window to see what was going on. What she saw scared her, there were over thirty death eaters right at the ward line, all casting spells against her wards which she could feel were rapidly weakening. She tried to apparate, but it seemed as if they had placed up wards of there own preventing her escape. Realizing this, Lily started activating her traps.

When her wards finally broke a few moments later there were several explosions coming from her front lawn. This caused Lily to smirk.

"And the idiots scoff at muggle technology, I'm just glad I don't have any dogs to walk. Keeping them away from the land mines would be too much of a hassle."

Unfortunately the DE got rid of the rest using various spells to set them off or get rid of them. Once the way was clear they started advancing once more. Seeing this, Lily ran to her basement and set up the siege wards to keep them out. On her way down she activated a ward in the wall that would steadily release a fast acting poisonous gas that would kill anyone who breathed it in and wasn't already immune. It took a few minutes to take effect, but only one breath was needed to secure their fate. By the time they realized the air was poisonous it was already to late. Lily waited for several moments before checking to see if there were any left using a ward that she had set up that was based off of the spell "Homenum Revelio" that allowed her to see any life forms in here house and what species they were since werewolves and vampires had distinct magical signatures due to their unique powers and conditions. Most of the magical races had a magical signature unique to them, but she was only worried about werewolves and vampires since they were the only ones working with the Dark Lord that could survive her poison.

When she activated the ward, it showed no signs of these creatures, but it did show one that disturbed her. At first glance it appeared to be a human, but when she looked at it closely she could see something that appeared to be corrupting and consuming it and replacing it with its own. What ever it was her magic could not identify the taint which could mean one of any number of things, though she could count on the fact that it seemed to be a possession due to the way the darker signature was eating at the humans. This was likely why they were still alive since the undead can't be re-killed with poison.

Seeing as there was only one left she decided that she would get rid of it herself. She opened the door ready to cast 'diffindo' when she saw who it was on the other side. To say she was shocked would be an understatement. Standing in front of her a staring at her eerily was James Potter. Though something was clearly wrong. Instead of an unruly mane of black hair, he had straight white hair, with two horns jutting out the front of his forehead. And where there were normally two brown eyes, there were four blood red horizontal slits.

(R trigger upcoming)

"Ah, so you must be Lily" he said "This fool here has told me so much about you. When you rejected him a few nights ago he decided he would look up a ritual that would make you love him. And while he had certainly found one, the idiot messed it up and instead summoned me. The fool tried to resist but he had such a weak mind that it was very easy to take over." he chuckled darkly at that. Then he looked at her intensely with a gaze that both terrified and disgusted her.

"Now normally when someone summons me, I either destroy or conquer there world. But since he showed such a lovely conquest, I decided I would simply take what he thought was his."

The way he said that with they way he was looking at her terrified her. Did he mean what she thought he meant. Was he going to try to 'conquer' her. If so then she really needed to get out of there. She tried to run but suddenly realized that she couldn't move. Seeing her struggle made him laugh before he slowly advanced toward her.

"Come little flower, it is time for Trigon the conqueror to conquer."

And then Lily screamed.

(R over)

(Three weeks later)

It had been three weeks since the attack, three weeks since Jame's possession, three weeks since she was violated in one of the worst ways possible. She felt dirty, like she was worthless and weak. She had thought about ending it several times, but every time she was about to work up the nerve, an image of Alice and her unborn child would appear before her making her remember that she still had to stay here. If only to make sure this didn't happen to them.

She was afraid to close her eyes, for every time she did, she would see his cruel smile. She rarely slept since she would have horrible nightmares were she would relive what happened. She was starting to get sick and would often throw up whatever was available in her stomach after she woke up. Because she had barley been eating it was usually just dry heaving or stomach acid.

As much as she dreaded it she was too tired to stay awake any longer. So with small tears in her eyes she laid down and closed her eyes.

(Dream)

The dream started off like most of her nightmares do, with him standing over her ready to "take what was his" when suddenly he went rigid. Suddenly two small clawed hands burst out of his chest. They moved in opposite directions, tearing him in half. When he fell she able to see who had saved her, and she was shocked. Standing where Trigon had been a moment before was two small girls. Their face were similar and they even looked like her when she was a child but that was not what shocked her. What shocked her was the rest of their appearance. The one on the left had blood red skin, sharp black claw like nails, deep violet hair and four blood red eyes. The one on the left had dark purple skin, Blood red hair like hers, sharp black claw like nails, and four emerald green eyes.

After a moment of just staring at them, they started to fidget and look at her slightly fearfully. This confused her, why would they be afraid of her when they had just saved her. Then she realized something, she knew who they were. Even though she had never met them before or was even aware they existed she knew how much they meant to her. And then she realized why they were afraid. They were afraid she would reject them, abandon them. Once she realized this she instantly ran forward and held them close to her all the while crying. She would never abandon them, no matter the reason, no matter who their father was. Because even though it didn't happen how she would have wanted, she would never abandon her little girls, her darling daughters.

(Dream end)

Unbeknownst to Lily, a prophecy was made that night, one that foretold of the end, one that spelled death for countless lives.

"the twins of hell are coming... Born of a mothers torture, born as the tenth month dies... The masters shall try to destroy them, for they may bring about their end... for if they fail, the world shall be theirs to conquer or raze... the twins of hell are coming."

On that night Lily had met her daughters, she knew that she had to make sure that nobody found out about them. To many people would try to get rid of them or take them from her. And nobody was going to take her precious daughters from her. Even if that meant she had to slaughter every last death eater her self, nobody would take them away. For the twins of hell were coming, and their mother would become a goddess of death to all of those who even thought about hurting them.

End

And that's a wrap. Part two should be up in a few days and it will cover the birth and first few years of the twins lives. Tragedy will strike, and important people will be met. Families will shrink and families will grow. And who is this red eyed woman that just burst through the front door covered in blood. Well it's going to be an interesting ride that's for sure. The harem list, side pairings, and some information you might want to know is just below.

Helena and Ravens confirmed Harem(yes it's large, I'll explain that after i list the pairings): Luna, Natalie, Daphne*, Susan*, Ginny*, Hermione, The Black sisters*, Nymphadora Tonks, The Patil twins*, Tracey*, oc werewolf, oc vampire, and ?*, ?*, ?*, ?*, and ?*(? to be revealed later if you can guess one of them than you get to decide to add any one you want from the undecided list, or try to convince me for some one not on it, or even your own oc)

(*) mean that I plan to add them to the harem in a later arc

Undecided(try to convince me if you want): Hannah, Lavender, any of the female professors(Dolores doesn't count), Pansy, Cho, the gryffindore chasers, Apoline Delacour, oc witch(ex Draco's sister, Sirius's daughter), oc succubus, oc lamia, oc fae, oc mermaid, oc satyr, oc demon, oc alien(preferably star wars or dragon ball z), oc not listed.(now as they are undecided I could at any time decide to add them on my own so be aware of that)

Side Pairings

*(Lily x Seras x Integra x ?)

(Flitwick x ofc goblin)

(Snape x ?)

rest if any undecided(if you want to know about the ? and don't care about spoilers then just PM me, The same applies for relationship mechanics, and future relationships that affect the harem, and anything else in the story in general)

Harems Size: Okay, so onto the harem's confirmed size, and even larger possible size. I'm not gonna bull shit you and say that they love all of them, or at least isn't in love with all of them. I'll explain it better next chapter since you'll learn more about Helena and Raven so that it will make more sense. What i will say now is that even though they're not in love with most of them, they do still care for all of them greatly, and would not get in there way if any of them fell in love with some one outside the harem. Hopefully that will pacify some of you who dislike large harems, though rereading that, that sounds almost exactly why some people don't like harems in the first place. But like i said before, why they may not be in love with all of them, they will still love the if that makes any sense.

Now on to the subject of lemons, I honestly don't know if I will have any. While they would completely fit with the story I am pretty sure I would be trash at writing them. So if enough of you want it, or some one writes one for me, then I will add them, but I will be posting them on a different site since I dont want this getting taken down in case fanfiction starts another story purge again and I know not everyone wants to read them.

Have a good day everyone.

1. I know the map doesn't show the houses in canon but as I said before, there wont be much canon in this story, and with the invisibility cloak it wouldn't be all that hard to at least find out were the dorms are.
