I EDITED PART 1 FOR SPELLING, GRAMMAR, AND FLOW. IF YOU HAVEN'T ALREADY, PLEASE TAKE A LOOK.
Author's Note: OK, so I ended up writing WAY more stuff for the prologue and decided to post it as a separate chapter instead of making you all read the updated first chapter over again. Though, since I went and edited the spelling and grammar, as well as fine tuning a few things here and there to make it flow better you might as well read it again anyways. Or not. It's up to you.
EDIT: Just like before, I have edited this chapter for spelling, grammar, and flow.

"I said no, Lucy! Why can't you understand that I don't WANT to go back?"
"Because you are obviously lying to yourself, Mira! We sleep in the same bed roll; I can FEEL you crying about it at night!" A familiar sight greeted the summer morning as Lucy and Mira argued loudly about the Take-Over mage finally returning to her guild, more than a year after running away from them with no word.
"Okay, so I miss them!? That doesn't mean I want to just run off and leave you here alone!" The blonde Celestial Mage had started hinting that Mira needed to return to her siblings months ago, shortly after the blue-eyed girl had gone through a terrible spell of depression that left her both distracted and weak. Mira; however much she might miss her siblings, was almost irrationally afraid of returning only to be rejected by them, as well as not wanting to leave Lucy behind.
"I won't be alone, idiot! I have Aquarius and the other spirits!" Said spirit nodded in agreement from where she was floating while watching the girls argue. "Besides, who said you can't come back to visit!?"
"What?" The blue-eyed girl felt like hitting herself, having been so anxious about even the thought of returning that she had completely missed the obvious.
"IDIOT! Did you really think going back meant we could never see each other again!? You KNOW where we LIVE!" The blonde was practically pulling her hair out in anger, she had spent weeks going back and forth with the other girl about this and getting nowhere, only to find out that the other girl had FORGOTTEN about the MANY ways they could keep in touch. "Hell, my DAD has been sending us letters and care packages regularly for this entire time! STUPID!"
If Aquarius wasn't a magical floating mermaid, she would have fallen off of her perch in a fit of hysterical laughter at the scream of frustrated rage that Lucy had released before stalking away from the campsite clearing.
"Sigh~ I... am an idiot."

*Lucy~ you just have to go on this mission with me! It's absolutely perfect for us!*
Lucy sighed at the pleading image of Mira that was reflected in the small communications lacrima she owned. The Take-Over Mage had been trying to get the blonde to go on a guild sanctioned mission with her for the last few months, though Lucy was almost positive it was against some sort of rules somewhere.
"I don't know Mira. You said that last time, and the time before that, and the time before that. Even if I HAD said yes to any of those, your Master refused to let you 'solo' them because they were too dangerous."
*That's why I told him the truth! He kept asking me why I refused to form a team with anyone, and why I always want to take these types of missions solo, so I told him that I was planning to do them with my free-lance mage friend and our mentor.* The girl gave a big smile as she spoke, proud of out-witting one of the obstacles to her goal.
"He went from 'No, it's too dangerous to go alone', to 'Sure, you can go on this highly dangerous quest with these people whom I have never met', just because you said you were going to be with friends? Is your Master some type of crackpot?" Lucy was shocked that a supposed Guild Master would do something so irresponsible.
*Well~ I may have had to tell him that you and I were currently on equal footing in our spars and that our mentor was the Guardian Spirit Aquarius before he would agree, but~ once he got past the shock he was quick to say yes.* The Celestial Mage face-palmed at the obvious embellishment of the truth, knowing that it was more likely that the man had to be pestered for a week straight before finally agreeing in the end. She could understand how he felt.
"Fine. What's the mission and where am I meeting you?"
*YAY~* Mira clapped and jumped in joy as she finally won over the blonde, only stopping when Lucy repeated her questions about the mission. *Sorry~ But the mission involves a low class demon harassing some villagers from its cave nearby in the country side, and they have a silver key as part of the reward. See~ perfect!*
"I agree Little Demon; it sounds like a perfect training opportunity for the two of you!" Both teens jumped in surprise as Aquarius joined their conversation. Neither of them liked that she seemed so very excited about going on this mission, especially since they were in agreement that anything the Mermaid considered training they considered as its own version of hell.
"Now, how do we get there?"
Small Cabin 10km X of the Fiore Magic Library Summer X780
"Alright you two, it's time we had 'The Talk'." Aquarius floated before Mira and Lucy; the girls sat on a log they used as a bench by their fire pit, each of them fidgeting gently at the mermaid's tone of voice.
"What's, 'The Talk'?" Lucy was the one to ask, having less exposure to people in general than Mira, and to things like love and sex specifically. The silver-haired girl blushed bright red at the question, but made absolutely no motions to answer.
"It looks like Mira already has some idea of what I'm talking about, but, I'll be honest with you, Spirits see this subject much differently than humans do and because of that I'll be giving you the condensed Spirits version." The mermaid spoke bluntly, watching the girls reactions as she spoke and seeing interest in both sets of eyes.
"Now, 'The Talk', is how humans generally refer to a parent or guardian informing their child about sex and love. They find the discussion to be embarrassing since they are generally brought up to think of sex as something, not dirty exactly but not talked of except with your preferred partner. Having helped raise Lucy, I did my best to keep her away from those types of human conceptions wanting her to be comfortable once this time did come." Looking at the girls Aquarius could see that she had done a good job, as where Mira was still blushing red in embarrassment just from the topic; Lucy was absorbing the knowledge without hesitation, the same as she did with any new information.
"We'll start with what humans tend to see as the 'proper' form of romantic love; the relationship being similar to what I have with Scorpio. Though sex is not exactly necessary to have a healthy relationship of any variety it is often a component in romantic love, and this particular form of relationship is generally between someone who identifies as male, and someone who identifies as female."
"Aqua-nee, what do you mean by someone who 'identifies' as a male or female?"
"Spirits have been around for longer than there have been humans, and in that time we have continued to change from what we once were. To us, there is no permanence in the concept of 'male or female'. Many spirits find it easiest to attribute a particular gender to themselves as the situation, their desire, or their summoner calls for, while others will keep to one or the other for a majority of their existence. Some prefer to remain without gender entirely, and yet others consider themselves to be both male and female all at once."
"How about you Aqua-nee? Have you always been just a mermaid, or were you once a merman?" Lucy seemed to be in deep thought as she asked the question that seemed most pertinent to her.
"First off, asking that kind of question can be considered rude, so it's best to just take these things at face value unless specifically told otherwise. As for myself... I think I was male for a while when the stars were still new, but I honestly can't remember that far back." Aquarius noticed that Mira finally seemed comfortable with the conversation, as she had stopped blushing and instead leaned forward eager to learn more. She decided to continue with her lesson.
"Continuing on, the next most common form of romantic love is one that involves two people who identify as the same sex, for example two women, or two men, in a sexual relationship. Generally speaking, the relationship itself is similar to one between opposite sexes, with of course the physical act of sex being the largest difference." This time she caught both girls blushing lightly, probably thinking of the kiss they had been sharing right before she had decided to interrupt them for this very talk.
"There are romantic and non romantic relationships that involve sex for any number of pairing types; for example a close friendship that includes sex as a means of comfort, bonding, or play, while sexual in nature is not necessarily romantic despite a mutual feeling of some form of love. There are also those relationships that can involve multiple partners, whether all the participants are equally with each other or they have agreed to only certain combinations with each other." She paused for a second thinking of how to best explain what she had learned over hundreds of years and countless life experiences in the simplest of terms.
"Really, I could probably have summed this whole conversation up with, 'each person is unique in their identity, and their expression of love. There is no one right way to love someone, and as long as it is agreeable for all of those directly involved there is no defined wrong way to love someone either. Love is Love.' Though, I guess I should also mention that while there are healthy relationships of all types that should be allowed to flourish, there are just as many unhealthy ones that need to fade away in order to protect those involved. In that, at least, both Humans and Spirits can agree fully."
"That was beautiful Aqua-nee!" Lucy was looking at the Mermaid with starry eyes; her life philosophy expanded that much further by the spirits take on love.
"Thanks, but I did say 'The Talk' was about love AND sex, right? We've talked a little about romantic love, and I know the two of you understand the concepts of Family and Friends well enough. So now we talk about sex; what it is factually, what it can mean to those people involved in the act, safe sex, the consequences of unprotected sex, and finally basic techniques and fetishes. Any questions?"
"Yeah, why the hell is Mira so red?"
Small Cabin 10km X of the Fiore Magic Library January X781
"Damnit! I can't believe that armored hussy got S-Class before me! Stupid Cheating Bitch!" Lucy watched with feigned interest as the agitated Take-Over Mage paced the confines of their small cabin, ranting and raving about her loss in the S-class exams only two weeks ago.
Personally, she couldn't care less about the title, but knew that Mira wanted to be able to take missions that involved higher level Demons so that she could continue getting stronger. After all, a Take-Over's power was limited by the physical form of the creature they absorbed. As it was now, Mira was actually stronger without using her magic than the first Demon she ever obtained.
"That does it! Lucy! We're going hunting!" The blonde was snapped out of her thoughts at the sudden turn of conversation, confused by what the other teen meant by 'hunting'.
"What's that supposed to mean?"
"You heard me! I snagged all the Demon and Celestial Key related quests from the guild board before coming here! We're gonna do them all and get stronger, then I'll show that stuck up red-head not to look down on me!" Lucy was nervous now; Mira was REALLY worked up this time, so much so she was starting to sound like Aquarius when she got on one of her 'training time' rants.
"Uh, aren't you supposed to get those approved by your Master before doing them?"
"That's the best part; since there were only 5 quests he went ahead and approved all of them for me!" The smile Mira wore as she said that did not fill Lucy with the warm feelings she usually got around the other girl; in fact it kind of terrified her. That Aquarius had apparently heard the entire rant and was just as willing to send them into the unknown made it all the worse.
The blonde let out a tired sigh before smiling at the two nuts she was saddled with for the long-term. "Alright, I guess I'm in. Where do we head to first?"
'The things we do for love.'
Small Cabin 10km X of the Fiore Magic Library Late Spring X781
"Are you sure this is a good idea Mira? I know you want to get stronger and all but..." Lucy watched as the Take-Over Mage continued to prepare the area for her upcoming spell attempt with the help of Aquarius, the Mermaid surprisingly subdued as she worked.
"I know it's dangerous, but the Satan Soul spell is MADE for Demon Take-Over mages. If it works right, I'll be much more powerful overall and far less prone to listen to my demons in the heat of battle." Despite sounding confident, Mira looked as nervous as Lucy felt.
"That's because you won't HAVE any demons, you'll BE the demon! Literally! You're merging THEIR essence and abilities with YOUR body and magic to form a whole new self! You could essentially die, Mira!" Lucy was getting desperate as she tried to talk her friend out of performing the ancient magic once more.
"Damnit Lucy! I know all that!" She turned to her blonde friend in misplaced anger, pointing desperately at her head as she did so. "But I want to be able sleep again without hearing their annoying fucking whispers!"
"Sigh~ I know. I'm just... worried." Biting her lip in apology, Lucy continued on with more confidence as she reached a decision. "But, I'll help anyways. You need to do this to be truly happy, and that's all I really want for you so..."
"Thanks." Brown and Blue eyes locked, filled with understanding and love. They would have hugged each other if not for a loud 'Tch' from the UN-happy Mermaid reminding them she was there. "We should finish helping Aquarius."
"Alright, but I want you to promise me something before we go through with this." Brown eyes bore deeply into blue, determination shining bright as she spoke with authority. "Promise that you won't listen to those ass-hole demons for even a second! YOU are the one in charge of YOU, and if I have to save you from even one of those idiots I won't let you live it down for the rest of our lives! Got that!?"
Mira looked at the determined blonde, her posture radiating authority as she pointed imperiously at the silver haired girl. The image of her standing there with such assurance combined with the words she spoke filled the blue-eyed mage with a new found confidence. Cracking a grin, she answered in the only way she knew how. "Got it."
"If you two are done flirting over there, I already finished setting everything up."
"Sorry Aquarius. Thanks for all the help with this though." Mira smiled at the agitated spirit gratefully as she took her place in the prepared area.
"Don't thank me until it's over brat. The spell is going to take a lot out of you, so you need to subdue ALL the demon essences before you run out of magic. Remember, you only get one shot at this so concentrate and get it done!" Standing side by side with her key-holder, Aquarius wished the girl before her a silent good luck.
"Mira!" Lucy's sudden yell drew the attention of both other girls. "You had better win quickly if you ever want to be able to kiss me again!" Mira smiled dreamily before suddenly filling with a new determination as she began the spell. Aquarius snorted in mild amusement as she realized which one of the two friends was actually the perverted one in their relationship.
Later...
The spell itself had taken only minutes to invoke, but the intended effects had no set time frame according to either Old Man Crux or the book they had found it in. It all depended on the mage, the number of souls they intended to merge, and the will power of those involved. Thankfully, the combination of Mira's magic power and will managed to overwhelm the five low level demon souls she had acquired in her preparation for this very spell; the battle of wills draining the Take-Over Mage completely but also taking only a little over an hour all together to finish.
For the two watching the spell it had been beyond horrible. Each demon she conquered and merged with herself had changed some physical part of the Take-Over Mage irreparably as she stole their essence and power for herself in its entirety. Little by little she had forcibly changed to become an entirely new being before their very eyes.
The worst part for the pair though was the obvious torment each change caused as it occurred. Mira's pained cries echoing through the air in time to the cracks of bone shifting and the tearing of flesh as her body changed its shape over and over again. If they had not been determined to endure this sight as a testament to their love of the Take-Over mage, each woman would have turned away 10 times over before the end had finally come.
Standing before them as her newly reborn demon self, naked and exhausted from her ordeal, Mira managed to utter only a short statement before collapsing unconscious into their arms. Despite everything that had occurred up to that point, both Celestial Spirit and Mage smiled.
"I win..."
Small Cabin 10km X of the Fiore Magic Library January X782
"WHOO! You are looking at Fairy Tail's newest S-Class Mage baby!" Said mage was currently dancing like an idiot in the enclosed space of the cabin she had come to call a second home.
"Congratulations Mira! I knew you could do it." Watching the childish dancing with a smile, Lucy couldn't help but find the other mage absolutely adorable in her enthusiasm.
"Yeah! I was already a shoe in candidate from last year, but Satan Soul Mira put me over the top! I even beat the crap out of Erza~" She broke off into maniacal laughter at the memory of one-upping her rival before stopping it to pout as she remembered what Master had ordered immediately after she was crowned the victor. "Can you believe Master said I'm not allowed to fight with Erza anymore? That totally bites~"
"Actually, I can. You and I can end up causing tons of damage when we spar seriously, and Erza is obviously on the same level if all of your complaints about her are true. If the two of you went at it even semi-seriously there would be a lot of broken buildings to repair. I don't think your Master wants to spend all that money every time you think rearranging her face would be better than just walking away."
Mira took on a serious face of contemplation as she walked over and dropped onto the bed next to Lucy, snuggling into the other girl's warmth without thought. Lucy, used to these sorts of moments, simply turned herself to better cuddle with the distracted mage as she let her work out whatever it was she was thinking so hard about.
"Do you think he would let me fight her if I promised NOT to use magic?" The question was said with such sincerity that Lucy couldn't help but laugh at the other mages cuteness. "Don't laugh Lucy! I was serious!"
"I'm sorry, I'm sorry! But, you're just too cute sometimes!" Pouting at the blonde, Mira rolled to face away from her without leaving the warmth of her arms. She was only slightly miffed that the other mage had laughed at her, but knew it wasn't meant maliciously. Plus the blonde had called her cute which always made her happy. "But... I'm sure he would let it slide if you got Erza to agree to also not use magic when you two fight in the guild."
"Really!?" Mira was quick to turn herself back over and face the blonde at those words, a large happy grin taking over her face at the thought of beating Erza's smug face in whenever she wanted. "You're so devious sometimes, Lucy~ I love it!"
The words were punctuated with a quick excited kiss to the lips, which turned into a second longer kiss, and then a third. More followed and soon enough so did hands as teenage hormones took full control of the situation, leading to a very NSFW experience between the girls. Unfortunately for them, Aquarius proved that she still had the same knack for horrible timing that Layla had cursed repeatedly over the years as she materialized in the human world at the 'height' of their time together.
The Mermaid didn't stop laughing at the pair's embarrassed faces for a week.
Small Cabin 10km X of the Fiore Magic Library Late Fall X782
Rain fell steadily against the roof of their tiny cabin, a fitting accompaniment to the heart wrenching sobs being emitted by a distraught silver-haired mage. Wrapped as she was in the warm embrace of her dearest friend, Mira felt safe enough to let all the pain she felt at her sister's death flow free. An unwelcome surge of magic triggered by her emotional state had the Take-over mage changing forms against her will, her magical control completely shot from the effects of deep trauma.
"Sorry-"
"Don't be! Just take your time and let it out, I've got you." The celestial mage tightened her grip on the currently demonic figure of her best friend, wishing she could absorb the others pain but settled for making sure the blue-eyed girl felt safe enough to share it with her as much as possible. "I've got you."
Some days later...
They had spent days just hugging and crying as Mira mourned her loss while Lucy did her best to comfort the distraught mage. Many times had the eldest Strauss sibling's magic flared with her emotions, often triggering a transformation into her Satan Soul and back without meaning to. Lucy took the transformations in stride, seeing no true difference between one form and another since they were both Mira's real body in her eyes, and simply continued whatever they had been doing as if nothing had changed in the slightest.
Aquarius, uncomfortable with the show of raw human emotion chose to leave the two girls to themselves unless otherwise necessary. Though the mermaid spirit cared deeply for the Take-over mage in her own way, she knew that she was not exactly tactful when it came to human sorrow and chose to leave the majority of the comforting up to Lucy. Plus, she really didn't care to 'walk' in on the two during another intimate moment should the comforting happen to shift into a more physical territory; the last two times she had done so being more than enough for all parties involved.
However, today the spirit planned to address an important concern that couldn't really wait for much longer. Carefully she peeked into the one room cabin they all called home, and seeing only sleeping mages chose to wake them up in a somewhat gentle manner. A glass of ice cold water later and the blonde mage was wide awake and hissing at her like a wet cat. "What the hell was that for!?"
"I know she's still upset, but we have to talk about something important. Wake her up and meet me outside once you're ready." The mermaid was all business as she spoke, quickly leaving the second she was done speaking.
Several long minutes later the pair of mages exited the cabin and came to a stop in front of the currently Human looking Water Bearer. "If you called us out here just to talk about how great your Human legs are again-"
"Idiot! That's not what we have to talk about!" The spirit cut off the blonde before she could finish her sentence, and chose to concentrate on the matter at hand. "We need to talk about the Little Demon's Magic, or more specifically her current lack of control."
"Hey! It's not her fault! She'll get better we just have to give her time!"
"Shut up Brat! This is serious!" Aquarius shut the protesting blonde up with her most fearsome glare to date. "I'm not saying that she can't mourn or be sad about her loss, but Mira's magic going out of control like this is dangerous! The most important reason being that Take-Over mages literally absorb the creature they become and suppress its will with their own. While her base Satan Soul is no different from her human body in terms of will and control, The Demon Sitri is another matter entirely."
Both teen-aged mages took the mermaids words into serious consideration. Lucy was shocked, and also a little bit scared since she had no love for the Will behind the Demon that had almost killed the three of them and enjoyed every second of it. She was especially not happy with the thought that it might over power and then take Mira from her in order to live free once more. Mira on the other hand, remembering all the warnings that went along with the learning of her magic, had already figured this was the case the first time she had changed against her will on the day of Lisanna's death. It was actually the main reason she had chosen to leave the guild and thus her little brother behind once more.
"I sort of figured that was the case." Though still deeply depressed, Mira was determined to be able to work past this issue so that she could safely return and comfort her remaining sibling.
"What!?" Lucy's head swerved to look at the blue-eyed mage so fast her neck cracked.
"Good, you actually paid attention to the warnings about using the advanced forms of Take-Over magic. Now comes the hard part though." The teens minds flashed back to all the years of dealing with a sadistic Aquarius and the torture that she had considered 'training' as the Mermaid gave them a familiar menacing smile.
"Time to train~"
Small Cabin 10km X of the Fiore Magic Library Early Summer X783
"I think that's about all of it. Who knew we had so much stuff?" The three long-term inhabitants of the tiny cabin were hard at work packing everything away. While not a lot of items had been accumulated over the years of their stay, it was more than enough to fill the two large wheeled suitcases and single travel pack to the brim.
"At least it's still manageable, you should see the amount of things my brother has managed to gather since joining Fairy Tail." The silver-haired teenager took a moment to look over the campsite for any stray items as she spoke, not wanting to accidentally leave something behind.
"To be fair, people often tend to accumulate various items when they live somewhere long-term." Aquarius was also taking a moment to double check that nothing would be left behind, not really wanting to have to backtrack once they were on the road.
"True~ but still, about half of this stuff is junk Dad sent me and the other half is stuff Mira brought back from her missions. Only about a quarter of any of it is actually useful to us on the road." Lucy was gesturing to the three different bags as she spoke, ignoring the huffy glare from the take-over mage at the mention of her contributions to the items.
"Speaking of the road, are you sure you don't want to join us Little Demon? You know you are more than welcome."
"Yeah, I'm sure. I've been able to control my magic properly for a while now, and while I'll miss you guys, I should probably make sure my little brother is doing okay after everything that happened." Both Celestial Spirit and Celestial Spirit Mage nodded, agreeing that it was past time for Mira to be with her remaining sibling. "Besides~ this way I can make sure you have a reason to come and join Fairy Tail!"
"I already promised I would, you don't have to bribe me into it!" The blonde mage pouted cutely at the blue-eyed girl, knowing perfectly well that she was being teased but unable to resist playing along.
"That's right, but who knows WHEN you would join if I didn't give you an actual reason to do so." The teasing smile Mira gave the blonde as she spoke widened at the sheepish grin she received in reply. "See, even you agree!"
"Okay, so it may have taken a while, but I would have done so eventually!"
"If you say so, but in all seriousness I expect you to show up before the end of next summer! I want to be able to go on adventures together as an official team; like you promised!" Mira pointed a demanding finger at her friend, daring her to say no to something she had been talking about for years now.
"Fine, I'll come to Magnolia before the end of next summer and join the guild so we can be a team. But~ you have to go that entire time without picking a fight with Erza!" Both Spirit and Blonde mage watched as a look of contemplation crossed the Take-over mages face, the silent war in her head written plainly on her features. They could both almost hear the girls thought process. Did she get what she wanted by sacrificing something she enjoyed, or did she keep the status quo?
"What if SHE starts the fight?"
"You can defend yourself obviously, but if you can end the fight without coming to blows then you had better do so. Malicious verbal arguments without violence count as fighting." The take-over mage went back to contemplating the choices. At this point both Aquarius and Lucy were a little surprised with how seriously Mira was treating the request that the blonde had thrown out there as a joke.
"Hnnnn~ fine! I'll do it!" Apparently Mira REALLY wanted Lucy to join the guild, since they were well aware that one of her all-time favorite things to do was bait her supposed rival into fights regularly. It was officially FAR too late for the blonde to even hint at the fact that she was only joking or she risked invoking the worst of the Demon's wrath.
"G-good! It's a deal!"

Ending Author's notes: As you can see this is gonna be REALLY AU.
Magic Theory with Aquarius Sensei- a guide to basic magic terminology
This section will be at the bottom of each chapter and will feature either; a quick rundown of the changes/theories I have on several forms of magic OR a set of Character information that features the changes made from official cannon. These are not necessary to the story, but may provide a bit of clarification and background information to the Alternate Universe I am building.
Today's topic: Magic Terminology
Celestial Spirit Magic- Celestial Spirit Mages use specially contracted gate keys as a magical focus in order to create a bridge between this world and the Celestial spirit realm, allowing spirits to cross over to perform various tasks as needed. The spirits use the magic of their key-holder not only to arrive, but to remain and function in the Human Realm, though they rarely stay for very long as it is physically painful for them to remain there. The act of summoning and maintaining a gate takes a large amount of magic from the mage in question though most mages do not understand the actual energy requirements necessary for even the weakest of Spirits. This lack of understanding has lead to the wide spread belief that Celestial Mages are weak or cowardly because they 'hide' behind the so called strength of their summoned spirits, a strength which is directly proportionate to the magical strength of their key-holder.
Guardian Spirit- A Celestial Spirit can form a contract within the bounds of Celestial Law that allows them to essentially 'adopt' a human mage in the same manner as the custom of legal god-parents. The contract must be approved by the Celestial Spirit King to be binding, as it allows the contracted spirit the freedom to move between the worlds under their own power at will in order to watch over their chosen mage. Aquarius' contract was approved based on her previous ability to open her own gate and the promise she had made with her previous key-holder Layla Heartfilia. Guardian Spirits are contracted for the Life of the Mage, and no magic beyond the destruction of either mage or key can break the bond.
Take-over Magic- Take-Over mages utilize a magic that absorbs the physical being of the target and subsumes its will with that of the mages, allowing them to freely use the creatures form and abilities as their own. Those mages with weak wills run the risk of losing themselves and being controlled in place of doing the controlling, especially against beings of advanced intelligence or will power such as the Beast King and various Demons.
Ancient Spell: Satan Soul- The Ancient Spell Satan Soul was developed specifically for those rare users of Demon Take-Over magic who risked madness from the number of demons they had absorbed over time as, unlike other creatures Demons retained their own free will and would often influence the mage over time in an attempt to wrest back control. Designed to essentially kill the Demon and steal its power in whole, the mage would gain a new take-over form in place of those they sacrificed upon successful completion. The new form is one that would suit the combined demonic abilities and was known as the 'other self' as the mage became capable of retaining their new body indefinitely, only requiring their magic to trigger the switch between the two forms instead of maintaining the take-over. Enhanced senses and minor demonic abilities are often retained by the mages 'Human' self as a side-effect of becoming a hybrid demon. "Though they retain a Human heart and Mind, they will have sacrificed the physical form of humanity for the intangible assurance of mental self. –Author's note on the spell for Satan Soul."
P.S. If you see any spelling or grammar mistakes, please forgive me as my spell check says that everything was correct. I don't believe it in the least.
