Title: Needed

Chapter 10

Disclaimer: Harry Potter and Sailor Moon belong to their respective owners.

I wanted to get the plotline running and so this one should prove to be interesting.

Someone asked about transforming into Sailor Moon and about the crystal. First of all, I don't think Serenity will be transforming, because it's a whole different world and there are some advantages of being a witch than Sailor Moon. As for the crystal, she still has it and carries it with her – it's the core of her wand. The crystal transformed into a wand when she wished for a wand: more details can be found in Chapter 1.

""""""""

Several attacks had occurred since November 13th. One of which had been devastating, almost to the point where Madame Pomfrey would have announced that a death had transpired, and the school would inevitably close. Thankfully, that it had not, all thanks to a certain white-blond haired Slytherin.

This incident occurred late Thursday night. The lich had, once again, managed to get inside the castle, despite all the wards that the Professors had placed, making it stronger than ever. While inside, the Dark Creature had captured a number of students of varying ages. They were students who happened to make an attempt of sneaking into Hogwarts' Library after hours, because of as assignment for Potions. It was their longest project yet, and none of the students wanted to do it over the Winter Holidays. Their plan had been carefully laid out; they managed to sneak out of the Ravenclaw, Hufflepuff, and Gryffindor Common Room with no problem and agreed to meet underneath a landscape painting on the Fourth Floor, not far from the library. Unfortunately, as they were making their way to the Library, the lich had come across the group of 10 students, instilled fear on them, and continued the process of taking a portion of their magic before dropping them carelessly on the ground.

Serenity had found them briefly after her encounter with Malfoy and was at a loss with what to do; there were too many students to levitate. Shockingly enough, Malfoy arrived shortly after the distraught Gryffindor and worked out the problem with her. After all, he was still a Prefect, he may not be a wonderful one and tended to ignore most students who asked for his help, but even in a situation as disastrous as the attack of ten students, even he couldn't turn a blind eye. It only led him to remember the muggles who had wandered into their estate, and died.

Therefore, much to the shock of Serenity Moon, Draco Malfoy offered to stay with the victims whilst Serenity ran to Madame Pomfrey. Soon after, the medi-witch arrived and, with the aid of Malfoy and Moon, proceeded to gather the students varying on the degree of their wounds towards the Hospital Wing.

But that was not where the problems ended. A few of the students had, by then, suffered greatly due to blood loss. Despite the multiple tries of cauterizing the wounds, the blood continued to seep through and by the time Madame Pomfrey managed to figure out the reason – the potions she had for them could only be supplied to half of the students.

When prodded about having Professor Snape to create the potion, the two students were informed that Professor Snape was not available and would not arrive until breakfast. The implied notion that was not missed to the two students was that by the time breakfast arrived, half of Madame Pomfrey's patients would surely be dead. A few seconds merely passed before Malfoy spoke up, proclaiming that he has the needed potion in his room and quickly left the Hospital Wing only to return a short while later, bearing the number of potions that would be needed to help the patients. Madame Pomfrey didn't question the student and Malfoy did not offer a reason.

That was the story of how a Slytherin had managed to save five lives that single Thursday night. And it was also in that night that a blizzard hit Hogwarts and by early Friday morning, the field outside was covered in nothing but iridescent snow, unblemished, cold yet beautiful.

It was also that early Friday morning that Serenity sincerely felt that maybe, just maybe Draco Malfoy was not as horrible as she was led to believe.

""""""""""

That eventful night occurred two days ago, but the attack from yesterday was thankfully not as serious. More and more students have had the misfortune of seeing a few of their classmates littered in the hallways or outside. Thus, less and less students have been willing to venture out on the grounds, and even the hallways. When Care of Magical Creatures came about, students stuck close together in groups, despite their knowledge that even that wouldn't save them from the monster that was terrorizing their school. There has already been written complaints from frantic parents, and it had already been scheduled that if the problem will not be resolved in the near future, they would be taking the students out and transferring them into another Magical institution.

It was evident by the recent actions made by several students and parental units that time was running out. If the matter with the lich will not be resolved, Hogwarts will surely close down for good. And that was not an option that several certain students were willing to take.

"Ms. Moon, if you will come with me," Professor McGonagall's stern voice came from behind the dazed Gryffindor.

"Professor," Serenity greeted, shaking the sleep from her eyes as she rose to stand.

The Professor nodded after a speculative glance before turning away, expecting the Gryffindor to follow.

"I'll see you guys later," Serenity hastily said, while picking up her book bag and hurrying after her Head of House.

Her friends simply took one look at the retreating Gryffindor before shrugging their shoulders, continuing with breakfast.

"Ms. Moon, I believe it is time to discuss about your progress in your academics and the path you will take after you graduate from Hogwarts."

Serenity sat, stunned. It had been quite some time since she had spoken in this fashion with the stern Transfiguration teacher. Of course, there were rare moments in which she visited the professor but neither one actually discussed about her future career or how her Remedial Lessons were doing. It was simply for pleasantries and advises in how to approach certain subjects. The same held true for her other Professors, the ones that she had gradually grown closer to in the previous summer, and hopefully, in the following summer as well.

Now sitting here, across from her Head of House, she was flabbergasted. She hadn't thought of picking a career since the previous summer, and even then, never dwelled too much in it.

"Professor, I…" Serenity stuttered, at a loss for words, "I don't know what my career choice is."

Said Professor simply raised an elegant eyebrow in response before bringing her right hand on top of a small stack of pamphlets and pushed them forward. Looking down at the papers, Serenity noticed they were leaflets about different careers in the Wizarding World.

"Then I suggest you start looking at them. You will not always be in Hogwarts, Ms. Moon and in a little under two years, you will be graduating amongst your peers," Professor McGonagall lectured, "Now, enough about that. I have received notice from your Professors about your Remedial Lessons."

At her words, Serenity couldn't help but shift uncomfortably in her chair. In truth, she knew that she wasn't faring at her best but she was sure that her performance was not wholly unsatisfactory.

Noticing her student's attitude, Professor McGonagall allowed herself a small smile of assurance and sure enough, Serenity visibly relaxed.

"Your Professors have informed me that you are doing well in their classes, and, as such, you will be allowed to drop several of your Remedial classes. If you choose to continue with some of them, please inform me. That time frame will be used to further your studies and enhance your academic knowledge and performance to the best of our abilities," Professor McGonagall informed the Gryffindor.

"Professor, isn't that…unfair?" Serenity hesitantly inquired, "I appreciate the opportunity to further my education, but…"

"There's nothing to be concerned about, Ms. Moon," Professor McGonagall interrupted the girl, fearing that if she allowed the young Gryffindor to continue, she'd continue to talk throughout the whole morning.

"Nothing…?" Serenity blinked, bemused by the turn of events.

"Correct," Professor McGonagall re-affirmed, "Although your grades are satisfactory and you have managed to catch up to your peers, your knowledge is only sufficient enough to get by. If you choose to, your Professors will continue to teach you what they have been teaching the lower-years for the past six years. All that is left now is to brush up on lessons that are not as… imperative for this year's lessons."

Serenity sat still, absorbing the information that her Head of House had given her and wondered if she should remain in her Remedial Classes.

"Professor, I believe I shall only resume the lessons with Professor Flamel," Serenity firmly decided, looking at the Transfiguration teacher in the eye, resolute in her decision.

The stern woman simply nodded in acceptance and took out a blank piece of parchment. With a wave and flick, a small murmur of words, a schedule was firmly held in place and she presented it to her student.

"It's not that I don't want to continue my other lessons," Serenity obligingly took the offered parchment, "But I believe that I need to concentrate on my Defense at this point. That and I can always continue the other sessions over the summer."

"I understand," Professor McGonagall nodded in agreement before rising from her seat, Serenity followed suit.

"Thank you, Professor."

"Don't forget to look through those pamphlets," Professor McGonagall merely advised before shooing the young woman out the door.

(Didn't Albus mention that Harry was taking private lessons with Professor Flamel?) Professor McGonagall mused as she locked her office door behind her.

As the thought struck her, a small smile appeared on her normally stoic face at the revelation. There was more to the reasoning than her young Gryffindor student was willing to admit.

"""""""""""

Blood-red with flecks of dark orange was all the young woman could make out before diving to the side, tucking her legs in the process. The new and foreign spell had been fashioned by the Defense Professor; when struck by the spell it would momentarily send a pain charm before releasing you. The magic bordered on being illegal, but since it did not, the Professor took it upon himself in creating the spell for his two students.

Thus, Serenity Moon and Harry Potter found themselves dodging the spell while trying to figure out a way to stop their Professor from directing it their way. It seemed that once the spell was created and found a target; it would do all it can to find you.

"Serenity, duck!" Harry shouted before pushing his friend to the ground just in time before the familiar spell passed overhead, missing the two by mere inches.

"Sorry, Harry," Serenity breathed, offering a smile up at the raven-haired man.

"Just be careful," Harry lightly blushed before pulling themselves up, making sure that the spell wouldn't come by any time soon.

"Harry," Serenity began, catching the familiar spell from the corner of her right eye, "Do you think we should try…"

"Wandless?" Harry interrupted, seeing the female tense beside him.

"Maybe; you tried that field of magic before but it didn't phase the spell at all."

"Well we only started it today," Harry pointed out, now seeing the spell visibly in their line of vision and it didn't appear to be changing direction any time soon, "Let's do it together, it worked last Tuesday."

"But we didn't do it wandless," Serenity stressed out, biting the bottom of her lip. Neither of them was allowed to use a wand today after Professor Flamel drilled them in wandless magic.

"Trust me," Harry whispered in her ear before pulling her a few paces back, gathering a bit more distance from the semi-powerful curse.

"Fine," Serenity mumbled, her eyes still trained on the spell before bringing her hands freely in front of her.

Together, the two cast a shield spell in front of them. It would only stop the curse from hitting them for a few seconds, and hopefully it would be enough for the two to finish the incantation.

Stepping close together, the two Gryffindors worked in unison. Their incantation, their hands moving simultaneously to the intonation of their words, and while doing so an aura appeared to life, surrounding the two in a mist of gray and white.

"Ibi concordia, ibi vitam,

Dum spiramus tuebimur,

Viva voce."

Hands and voices combined and their aura only became more intense by each intonation, by each syllable, and as the spell drew closer, both hands rose in the air.

"Inflamare Maxima."

Large bursts of flame erupted from both pair of hands, joining together as one before racing down the room to meet with the blood-red and orange curse. Upon meeting, a great eruption took place, toppling the two students to the ground, both mesmerized by the power the two spells created. Smoke, shattered glass and a damaged wall was left in their wake and once the smoke cleared, the ground was nothing more than a gaping hole that led to a thankfully empty classroom.

"Impressive how both of you managed to defeat my curse," their Professor praised the two, "If only you two were not so hesitant in joining your powers."

Both students hurriedly stood on their feet, flushing from their praise but all the same feeling ashamed that they had been so hesitant in the first place.

"With practice, you two will grow in power and strength. Before long, maybe you won't need to take so long in casting…" said Professor Flamel, before turning around and fixing the damage their joint powers created.

Afterwards, he took the moment to study the now exhausted figures of Serenity Moon and Harry Potter, "And you two won't be so tired. Sit down and recuperate, while doing so, reflect on your next course of action and how you can improve your magical abilities."

Smiling to themselves, Serenity and Harry sat down, taking the chance to reflect and speak with each other on how to strengthen their powers without being so magically exhausted. In the back, Flamel looked on a small smile on his face.

(You are finally moving on with your life…)

"""""""""""""

"Serenity," Serenity paused and turned around, smiling at the occupant of that voice, who else would she smile to so favorably if not for Harry Potter?

Their relationship from all the way back in Transfiguration had been the cornerstone to their inevitable friendship, the events that followed only added to it.

"Harry, weren't you going to go with Ron and the others for Quidditch practice?"

The raven-haired young man flushed in response but didn't move from his spot. Instead, he moved closer and swept back his hair, more in nervousness than anything else.

"No, it got canceled because Hermione insisted that they do their homework. Especially since Snape's assignment is even longer than he normally gives," Harry explained and shrugged, "You know how Hermione is…"

"I thought Ron wasn't taking Potions this year," Serenity blinked, a bit confused.

"He's not, but he has more homework than all the others put together," Harry smirked, recalling the positively red-faced Hermione yelling at Ron when she found out.

Serenity chuckled in response and was soon followed by Harry, the two stood there laughing away in the empty corridor. It was in these small moments that she truly enjoyed being with Harry, it almost made her feel normal, as if they had all the time in the world. There were no Dark Lords, no immortal beings or undead creatures; these rare times only consisted of the two of them, being two normal teenagers.

"So what can I help you with, Mr. Potter," Serenity grinned while walking up to the young man.

Grinning, Harry walked the rest of the distance and laced his hands with hers before pulling her towards the staircase that would lead them downstairs.

"Would you care for a walk around the grounds, Ms. Moon?"

"What would they say, there are dark creatures out there," Serenity smirked, her eyes glinting with undeniable mischief in her eyes.

"I don't know about you, but I'd rather face a dark creature any day than the wrath of a Miss Hermione Granger," Harry laughed and found that Serenity had joined him.

"If you put it that way, let's get out of here and fast!"

Laughing, the two hurriedly left the castle and ran outside, the first laughter to enter the Hogwarts Grounds since the first snow fall.

"""""""""""""""

"My Lord," a dark robed figure knelt down, his face nearly touching the cold ground.

For several minutes, the dark robed figure received no answer, but this was normal to the Death Eater. All the old recruits and some of the new ones knew that the Dark Lord was quite perverse when it came to finding some way to catch his Death Eaters off-guard, simply so he can punish them with a well-placed Dark Curse.

"Speak," the Death Eater heard his master hiss, feeling a small shudder enter his soul.

"Everything is going according to your plan. In a few days, we may begin," the Death Eater reported, repressing a shudder when he heard the familiar hiss that most assuredly came from his master's favored pet, Nagini.

"Pray that you do not disappoint me, Lucius," Voldemort rose from his seat on the dais and strode down, stopping several inches from the robed man, "I want everything perfect when she arrives."

"Yes, my Lord" Lucius replied, knowing that no other words would appease his master.

"Rise," Voldemort smirked, allowing his favored Death Eater to get up on his feet.

When Lucius Malfoy did rise, he resisted the urge to gasp at the sight that greeted him. No longer was the Dark Lord Voldemort the vile creature that they had seen earlier that year and the years previous. Instead, what stood before the Malfoy patriarch was a tall, handsome man in his early 20s, with jet black hair, distinguished and with a radiating aura that drew you to obey his words, and the only discerning portion of this young man that led him to believe that he was his master was the blood-red eyes that stared right at him.

"Go; make the necessary plans. I want our guest to arrive on Winter Solstice," Voldemort smirked and watched as Lucius bowed once before leaving his master's presence.

"On the night of greatest darkness and the longest night of the year, we shall meet again," Lord Voldemort hissed.

"""""""

Serenity visibly sighed, the pamphlets that Professor McGonagall had given her were informative but not one of them caught her interest. Being a Healer, Medi-witch, Auror, or working in the Ministry had their benefits and share of excitement but Serenity just knew that not a single one of those fields were meant for her. Her friends, family, and guardians would digress; after all, wouldn't the ex-future Queen of Crystal Tokyo be wonderful in the Minstry; wouldn't the ex-senshi, defender of Justice and Love, Savior of the World and the Universe be an excellent addition as an Auror; and lastly, wouldn't the ex-senshi, Princess Serenity, owner of the Legendary Crystal, granter of wishes and healer via the crystal be a miracle worker in the Medical Field of the Wizarding World? Despite all of her titles and achievements, Serenity Moon could not bring herself to enter any of those fields.

(This is a new world, a fresh start, a new me. If I am to remain in this world, shouldn't the current me be something else?) Serenity thought out, stuffing the leaflets back into her pocket, opting for the beautiful scenery of Hogwarts Grounds.

It had only been two days since Professor McGonagall had spoken to her, and two days since Harry had taken her out on Hogwarts Grounds to play in the snow. It was an unwise decision, but a memorable one at best. Shortly after they had tired from their chase and snowball fights, Filch had found them and shouted for them to come inside. After all, a lich was still wandering around and had attacked enough creatures and wizards alike that even Hagrid stayed inside the Castle, not that it helped the situation.

Turning away from the window, Serenity began her journey to the Entrance Hall. If she was fast enough, she could make it in time to see Hermione and the others off. Only a few students would be staying over the Winter Holidays: Serenity, Harry, Ginny, Ron, Draco, and Blaise. The other students, frightened of the lich, had scrambled to get everything ready in order to leave the school, and hopefully, convince their parents that Hogwarts was not safe and to please not send them back. Of course, there were a number of parents who had already made plans in not returning them for the second term. In the meantime, the Ministry had already been contacted a few days ago by the Headmaster, and was informed that specialized Aurors and those in the Department for the Regulation and Control of Magical Creatures.

(Not that they could possibly know how to control a lich if they have no knowledge of how to retrieve the phylactery.) Serenity mentally rolled her eyes. (It should prove to be difficult, if the one who holds that particular device is none other than Voldemort.)

"Serenity! We were wondering when you would get here," Hermione startled Serenity out of her reverie as she stepped down the last flight of steps that led to the Entrance Hall.

Looking toward the sound of the voice, Serenity smiled at the group of students huddled together saying their goodbyes and exchanging gifts. And in the center of the throng were Hermione, Neville, and Luna with Harry, Ron, and Ginny close by. Ignoring her past musings, Serenity strolled toward her group of friends.

"I'm sorry I couldn't go and buy you your gifts," It pained Serenity that since her untimely arrival to the Wizarding World, there was not one knut in her name.

"Don't worry about it, Serenity," Hermione smiled alongside Neville. Luna simply hummed, her eyes holding that same dreamy expression that made Serenity wary. There were strange things in the Wizarding World that Serenity came across, but Luna Lovegood was one of the strangest. There were times that Serenity truly wondered if she simply acted that way to avoid people, or if that was her true personality. In time, Serenity gradually grew to appreciate the eccentricities of Luna Lovegood, she was strange but an overall nice girl.

"Just make sure that you take care of these two while we're gone," Hermione grinned, looking at a frowning Harry and Ron.

"And keep Ginny out of trouble," Neville put in, smirking at a red-faced Ginny Weasley.

"Don't forget the Blibbering Humdinger," Luna stated, causing several heads to turn and give Luna a curious look before turning back to their original conversation.

"Sure thing, Luna," Serenity smiled, she found Luna's words always comforting, despite her oddity.

"We're not that bad," Ginny frowned, "It's not like I go out of my way finding trouble."

"Hey, we don't go looking for trouble!" Ron protested.

"Trouble finds us," Harry re-affirmed, an expression so serious that the others couldn't help but laugh at their antics.

"And who were the two that earned themselves detention with Filch two weeks ago, because someone was hungry?" Hermione pointed out.

"That was different!" Ron flushed; he had forgotten about that small excursion.

"Sure it was," Neville chuckled before turning his attention back toward Serenity, "Have a pleasant holiday, Serenity. I'll be back on Boxing Day, and I'll bring you something from my trip!"

"As will I," Hermione nodded and Luna mimicked Hermione's words, more or less before all three of their friends exited Hogwarts and onto the awaiting carriages.

"Well, that's it," Ron stretched, ruffling his red hair before turning around and looking at Serenity and Harry, "Let's go to the kitchens and get some snacks!"

"Ron, you just ate two hours ago!" Serenity exclaimed.

"Exactly, I'm hungry," Ron exclaimed and Harry and Ginny groaned at his words.

"Now that you mention it, I am feeling a bit hungry myself," Serenity thoughtfully said.

"I thought you were here to get us out of trouble, Serenity," Harry smirked.

"Well you guys do rub off on me," Serenity remarked, lacing her hands into Harry's, an act that didn't go unnoticed by Ginny.

"Glad to know," Harry grinned before following after Ron, neither one letting the other go as they made their way to the Kitchens with Ginny right behind them.

"""""""""""

"That was delicious," Serenity proclaimed, her head tilted back as she looked up at the blue-gray sky, a smile on her face.

She was currently on the perch of the Entrance door, not wanting to return to the Gryffindor Common Room just yet. Harry had wanted her to come with them up to the Common Room where it's nice and warm. She hadn't missed the way his eyes bore into hers, with the underlying meaning that it was also safer than walking around the school corridors, and especially, right outside the walls of Hogwarts. But she insisted that she would only be gone for a short while, and so, all three of her friends had reluctantly left.

(Ron should have already begged Harry for a game of chess.) Serenity fondly smiled (And Ginny would watch for a few minutes before taking out a Witch Weekly magazine.)

Suppressing a shudder, Serenity brought her school robes closer to her frame and tried to blend into a small niche near the doorway. If she had brought warmer clothes with her, she would have decided on a nice stroll, but she hadn't.

"Shouldn't you be inside, little cub?" a warm voice whispered to her ear.

"Malfoy," Serenity lightly smiled, she knew that the Slytherin would have found her sooner or later. It was a ritual they shared every day, even if the timing wasn't always the same. But if it was, people would have probably figured out the odd relationship the two shared.

"Moon," Draco smirked before tugging on Serenity's robes and pulling her closer to his tall frame, "Foolish Gryffindors, never one to think about the consequences of their actions."

"If I'm foolish, what are you?" Serenity turned around, an elegant eyebrow lifted up in query.

"Unlike you," Draco leaned in, his mouth dangerously close to her lips, "I'm not alone."

Serenity raised her eyes in alarm and began shifting around, terribly afraid that one of the Professors or one of her friends were right around the corner and glaring at her. She suddenly felt uncomfortable to be around Draco Malfoy, a feeling she hadn't felt since the early encounters between the two of them.

The Slytherin, however, didn't feel any of this; instead he had the audacity to laugh.

"And here I thought Gryffindors were supposed to be brave," Draco chuckled before sobering up, "Where's your bravery now?"

Before Serenity could respond, Draco pressed his lips against hers, deep and all consuming. This kiss, Serenity noted was different from all the rest, one that she had yet to experience and an indescribable feeling wormed itself into the recesses of her heart, her mind, and her gut.

His kisses and hers, when formed together, caused her to be lost in the bliss of heaven and hell but it was peculiar. In the heat of the moment, Serenity couldn't think clearly and so didn't think much on the matter, only absently noting that the kiss was more emotional.

And emotional was what one would describe the passion that the two shared. It was slow and sweet, fast yet firm. Lips locked together in an embrace that was deeper than all the others the two shared. Desperate, unyielding, and strong and just as Serenity gets a feeling of that exchange it suddenly changes; soft, inevitable, a kiss so soft and calm that it almost felt like a passing breeze. It was akin to drowning before suddenly changing to a feeling similar to being lifted up into the air and soaring into a calm breeze.

The kiss that Draco Malfoy bestowed upon her was a kiss of unimaginable proportions. The kiss that Draco Malfoy imparted to her was memorable; a kiss to last for a lifetime.

When it was over, Serenity was back to the telltale signs of a dazed look, rumpled hair and clothes, breathless, and bruised lips. Malfoy took the time to trace her lips and cheeks, memorizing her face as best he could before stepping back.

"Thanks," Draco whispered huskily into her ear before giving her one last chaste kiss and turning around, returning inside to the castle.

Several minutes later, Serenity slowly returned to herself and realized that she was still outside. A small smile on her lips, Serenity began straightening herself out and was about to enter the castle when she caught sight of a glittering object a few feet from where she stood.

Curious, Serenity left her spot and stepped onto the cold grounds. The object in question couldn't have possibly been there earlier or else she would have noticed it.

Who wouldn't? Even though it was small, there was an untold power that drew anyone to it and the item seemed to be shining so brightly that a person had to look twice to see what it was. And that was what Serenity had set out to do.

A few steps later, Serenity bent down on the snow and picked it up. There, on the palm of her hand, laid a ring. The simple yellow-gold band had an unnatural glow and at the center was a diamond serpent.

"Strange; who would leave such an expensive item on the ground?" Serenity mused aloud and drew closer to it, on the inside of the band there was a written inscription.

"Anguis in herba," Serenity read aloud.

(Doesn't that translate to, a snake in the grass?)

Right after those words passed her mind, the ring in question began to glow ominously before Serenity felt a tug on her navel and darkness enveloped her thoughts.

Unknown to Serenity Moon, just before she was transported away she had dropped her wand on the now empty embankment of snow. And it wouldn't be until later that night that someone discovered that Serenity Moon is now missing from Hogwarts; the only sign that she could possibly have been taken from the school was the wand left behind, a few feet from the Entrance.

To be continued…

"""""""""""""""""

This chapter was aimed solely to lead up to a closer relationship between Harry and Serenity. They aren't as physically involved like Draco and Serenity, but it's just as sweet. Harry, who hasn't really known love and isn't quite the expert as Draco would probably be, wouldn't fully comprehend as to what his feelings are toward Serenity. So he would treat these feelings with caution until he realizes what they exactly are. He already made a grand mistake with Cho Chang, and I imagine that he wouldn't want to repeat that with Serenity Moon, someone that he finds himself caring a great deal for.

Here are the translations for those Latin terms!

"Ibi concordia, ibi vitam, "There is unity, there is life,

Dum spiramus tuebimur, While we breathe, we shall defend,

Viva voce." With living voice."

"Inflamare Maxima." - Simply translated into "Large Flame."

"Anguis in herba,"

This one basically means a snake in the grass. But it could also mean: A treacherous person. That's probably a dead giveaway about what happened, isn't it?

One last note: if people are wondering about what Voldemort was saying about the night of greatest darkness and whatnot, that was inspired by Lightning on the Wave and then did a bit more research for the actual day; which is the 21st of December, I'll elaborate later.
