There won't be blood-shed

"There will be blood-shed! The man in the mirror nods his head." Dan sang quietly as he walked through the empty halls of Hogwarts.

The body of an Endermen was confusing. Dan figured that out pretty quickly and a week of calm under the protection of the castle confirmed it.

He didn't need to sleep as much as normal people and felt much more energetic at night. Although Dan still felt hunger, thirst was something he forgot about on the third day in this world. Which was convenient, because he wouldn't have to drink something that could very well burn him from the inside. He didn't need to go to the toilet or bathe because his skin didn't sweat and seemed to repel dirt, earth and even dust. He still cast a cleansing charm on himself every morning, just to at least feel cleaner.

Dan progressed quite fast in his studies of magic, theory and spells themselves came to him quickly, as if he had already done all this before. The feeling of déjà vu never left him while reading books or practicing spells, remaining in his mind every time he learned something new in magic. The first-year spells didn't take too long to learn. These were the basics of the basics, spells designed to teach children to control the flow of their magic. Of course, there were a couple of useful spells, Dan even reworked the Lumos spell into four spheres that flew around his body, but these were still far too easy. To tell the truth, theory took up most of his time because he couldn't read and understand the seven major books in one week. Not counting the additional ones, of course.

In part, this could be attributed to his past life, where he read about various spells and their effects, but it did not explain the cases when he stumbled upon another completely untouched section of magic. Druid magic, for example. But all this has nothing to do with what Dan was doing now.

Under the soft light of the moon, the only Enderman in Britain wandered the corridors of the ancient Swedish castle, trying to escape from the oppressive atmosphere of his room. It was too empty, like a roadside hotel room that you had moved into just to sleep and would be on the road the next day. Dan didn't have many personal items, and even those were already in their closets or drawers. There were no new things in the room since his last shopping trip, simply because Dan didn't even try to add anything new.

Of course, if we don't count the oddly shaped scratches that appeared on the walls after every time Dan actually slept.

As he walked across the castle's cold stone floor, Dan couldn't help but notice how much the atmosphere around him had changed. If during the day everything around breathed happiness and excitement, then at night even the walls glistened with unsolved mysteries. Approaching the moving stairs, Dan stopped. He heard the quiet voices of teenagers from somewhere below, but couldn't make out the words. Someone, like him, was wandering tonight.

'Hmm... Time to turn back, then,' he turned toward another corridor, but stopped when something reached his ears.

"–throw her in a closet. Let's see how Loony likes to lay naked there all night." The girl's voice was filled with dark anticipation.

Dan glanced down the stairs, but could only see the top halves of three female students, two of whom were dragging a struggling fourth. "Imagine what will happen when the door opens in the morning and everyone sees this freak!" The second girl almost shouted in glee, only for the others to start shushing her.

Anyone who sees these three will immediately understand that most likely they are not friends of the blonde.

Seeing such a situation, some would rush to save the girl without even thinking about the consequences of their actions. These people would confidently go to the girls and try to do something to prevent the brutal bullying and come out victorious in the situation by getting at least one friendship out of it.

Others would have helped the girl when everyone had left by opening the door and providing comfort to the victim. Maybe even promising to pour hell on offenders at the right time.

Dan wasn't that kind of person.

He wasn't going to play the hero when he wasn't. He usually didn't care about people he didn't know: homeless people, dogs on the street, old geezers who needed to cross the road; he ignored them all. If his family or one of his friends needs help, he will definitely help in any way he can. But going out of your way just to help someone you don't know? No thanks. Especially when there is an alternative that will bring more results.

One of the girls pushed the platinum blonde into the closet and Dan frowned.

"Well, that's not nice," he muttered and disappeared.

-=-=-=-=-=-

With Loony already in the broom closet, her eyes wide with fear, and her wand in Marietta's hands, all Sabrina had to do was jinx her clothes off and hit the door with a couple of locking charms.

Why did three exemplary Ravenclaw students decide to go for such a mockery? No one but them could know.

"Sweet dreams, Loony," Sabrina sneered. She really didn't like people like Lovegood. Just by their presence, people like her brought shame to the name of Ravenclaw! Not to mention her stupid newspaper, which is published by her equally stupid father! "Depone!" A bright flash of light blue left her wand, but to the great surprise of all four girls, it simply shattered on an invisible barrier in front of the door.

The girls quickly looked around and in shock noticed the deadly calm head of their house, who was standing near the stairs, his wand pointed towards the barrier. He stood in his blue pajamas, fluffy bunny slippers on his feet, but even so, his gaze made the girls tremble.

"Miss Gibson, what do you think you are doing?" The usual jovial notes in his voice disappeared, their place was replaced by steel.

"Professor!" She exclaimed, quickly trying to come up with some explanation that wouldn't lead to her being expelled. "It's not what you think! Loony–" That was a mistake.

"Her name is Luna Lovegood, if you want to pronounce it correctly," Flitwick interrupted her. "But please, do go on, I want to hear what explanation you can give me. If I'm not mistaken, you wanted to use a de-clothing jinx on Miss Lovegood while her wand was in Miss Edgecombe's hands." Marietta quickly tried to hide Luna's wand behind her back, but her hand stopped at the professor's words. He was looking at his students with disappointment. "Well?"

Sabrina lowered her head to hide her anger. Flitwick should have been in his office! Today was a Wednesday, and every Wednesday he evaluates his students' homework, what is he doing here?! It doesn't make any sense!

But alas, everything was quite simple. Dan teleported to Flitwick's office, quickly explained what was happening to him, and teleported him around the corner. It didn't even take a minute.

Dan met all the teaching staff at the school a couple of days ago and received a warm welcome, although Professor Sprout was concerned for the safety of the rest of the students, given his... Ahem... Dark nature. He heard Professor Trelawney whispering about Obscurus and decided to try and find books with the word when he could.

"As I thought." With a wave of the wand, the barrier disappeared and all the students' wands flew into his hands. Filius went to the door and looked at Luna, who just stared at him with wide eyes. "Can you stand, Miss Lovegood? You can be sure you're safe with me."

She nodded and pointed to her throat, making Filius not frown. "A silencing spell too?" He muttered and waved his wand again.

Flitwick was disappointed in his students right now. Not only did they want to embarrass their housemate in front of the whole school, but they also used Charms to do it! The subject he taught! But that was just salt in the wound, the main problem was still their unforgivable behavior. Even the Marauders never stooped so low!

"Thank you, Professor..." Luna said while rubbing her throat.

"You're quite welcome. Well, now I'll ask everyone to follow me to the Headmaster's office." He cut off all protests with one glare and motioned for the three girls to go ahead, Luna walking beside him.

Flitwick just couldn't believe the behavior of his students. How dare they bully a second year like that? What gave them the idea that they would go unpunished?! He wasn't going to sleep until he got all the answers.

Unseen by everyone thanks to Flitwick's spell, Dan walked a little behind, looking at the silver-haired girl in front of him with interest. If anyone could mistake her wide gaze for fear or shock, then Dan saw something else. Acceptance.

Artists were the kind of people who always saw more than others, like detectives who noticed a drop of blood where an ordinary person saw a mere stain. Luna accepted her own housemates' decision to shove her into a close completely naked as easily as she accepted her unexpected rescue. She tried to break free and fight to somehow save herself, but seeing that she had no other choice, she accepted her position.

Against her were three students, they were older, physically bigger and more magically educated, her chances were minimal.

It was jarring to see that in the eyes of a little girl who wasn't even tall enough to reach his waist. Humans weren't creatures that simply accepted the shit that was thrown in their direction, they fought even when there was no chance of winning at all, just to fight, to say that they did all they could. But Luna... Luna understood that fighting would lead to nothing. Resistance was futile, especially when she was already in the closet, wand pointed at her face. She was smart enough to plan her actions after the girls left her unsightly, even then she had several plans to escape as soon as they left.

The secret door to her left was one of those plans. The ax lying in the corner of the room was another.

But Professor Flitwick showed up faster than anyone expected. Luna didn't calculate his appearance in her plans, but she was pleasantly surprised. Walking naked through the corridors of an ancient castle is only fun when you do it of your own free will.

Dan was staring at Luna Lovegood's back and couldn't shake off the feeling that he wasn't watching her, but quite the opposite. The girl was smart, smart enough to probably understand that Flitwick's appearance was anything but accidental. And that raised more questions about how he knew about this act of bullying.

Although on the other hand, who will ask about what the Professor does in his free time?

Dan shrugged to himself. 'Oh, well. Not that it's my concern.'

It very much fucking was.

Luna glanced over her shoulder and looked straight at Dan. Their eyes locked, but his goggles prevented any rage, the little girl smiled in his direction and mouthed: 'Thank you, Umgubular Slashkilter.'

She turned around and continued walking as if nothing had happened.

Dan blinked and disappeared, teleporting to his room. He just stared at the wall in front of him, not thinking about anything.

Well, that wasn't quite true, he was thinking about Luna and how the hell a twelve-year-old girl could see through the invisibility that the Charms Master had placed on him. How long had she known of his presence? What could she possibly see? Falling onto the bed, he covered his face with his hands, swearing at himself. Flitwick and Dumbledore will want to hear his side of the story.

When his brain restarted, Dan could only ask one question in the empty room.

"What the hell is an Umgubular Slashkilter?"
