Realizing that he probably captured Bellatrix Lestrange, the eldest sister of the three Black sisters and Sirius Black cousin. Felix lightly paced around her body as his thoughts were slightly messy. Due to watching the movies, he knew a few things about her such as being Voldemort's right hand woman, her insanity, and the tragedies she causes.
While pacing, Felix rubbed his forehead trying to think what he should do with her. He didn't really need her to gain access to one of Voldemort's Horecruxes. Due to the plan he had in mind, he only needed access to one and he could destroy all of them in one go. Which in turn should block him from making more, but he isn't an expert on souls. Since Voldemort shredded his like a block of cheese, it wouldn't be impossible if a piece floated out and attached making a rough horcrux.
Glancing at her figure a few times as he couldn't help himself. Felix wanted to slap himself for acting like some sort of voyeur pervert. He just thought she was wearing a bikini, a very micro bikini. Bonking himself on the head as his mind began drifting again.
"What should I do with you?" Felix softly said to himself.
He couldn't bring himself to kill her nor did he want to. While he has killed a few Death Eaters before when they ambushed him last Christmas, he didn't like killing. Yet letting her go wasn't an option either nor keeping her tied up.
Then he saw the dark mark on her arm, a mark that looked like a black tattoo. From what he saw and knew, this mark of a skull with a serpent exiting its mouth allowed Voldemort to call his followers. It was an interesting piece of magic and in some fanfictions it was a slavery mark.
"Enslavement Magic?" Felix softly muttered to himself.
Lightly touching the mark, Felix opened up his ability to peek at the Paths and shook his head. It wasn't actually enslavement magic like in those stories. Instead it was a mixture of communication and a pain curse. Which made him wonder if the Death Eaters were masochistic for while the Pain Curse isn't as bad as Cruciatus Curse it wasn't light either.
While he muttered these words, Felix didn't like this idea either, since he didn't want to enslave anyone. He felt terrible thinking about it and as much as he wants to let her go and hope she can become a better person. Felix knew that this was more of his fantasy and wishful thinking than reality.
The chances of Bellatrix becoming a better person due to his actions like this was basically nonexistent. Tapping his finger against his arm as he tried to think of another idea that could potentially achieve a similar result. These thoughts either were either worse or not feasible, while a few seemed to hurt him more than if he just let her go.
After pacing for a few more minutes and seeing that her eyes were open watching him. Felix knew that using Enslavement Magic would probably be the best course of action. So after making sure that her bindings were secured, Felix sat at his desk while bringing out a journal.
"I never thought I would have to use this magic." Felix mutters to himself. "I should probably lock away this journal after this."
Peeking at the Path's once more, Felix became a bit pale for opening it once more in such quick succession. So moving quickly as he peeked at the enslavement magics, he quickly wrote out the instructions. After writing, he sat there for a while to recover from peeking before grabbing some ink and brushes from his desk.
Upon taking a seat next to Bellatrix, Felix watched as Bellatrix tried to struggle with the binding. Her eyes showed her anger and bit of craziness as she rocked back and forth. Yet, she remained mostly stationary and besides her extremely muffled screams, no sounds could be heard by normal ears.
"I'm sorry." Felix said softly with a heavy heart.
Then, he began to paint various symbols on Bellatrix's body. From her head to her toes, he wrote various symbols on her. There was a bit of struggling when he had to turn her over, but he managed with the help of magic. By the time he was done, it was like she had a body suit of tattoos on her body with very little space untouched.
"This step is done, now for the final part." Felix told her with a sad look.
"Mmmm!" Bellatrix muffled screams replied.
Finally, once he finished, Felix placed his hand in the center of her chest. While he blushed a bit, he soon used his magic and the markings rapidly lit up while Bellatrix glared and yelled through her gag mouth. Then all the markings converged underneath his hand where a new symbol appeared signifying that it was done.
Upon moving his hand a marking that signified the enslavement magic wasn't anything fancy, but it was a heart wrapped in chains. Felix had picked the design mainly for himself as even now after having done it, he didn't like it. The glare in Bellatrix's eyes slightly dimmed, but was still there.
"I'm going to untie you now." Felix said softly. "I want you to just sit up for the time being."
Following the command, Bellatrix did just that. She sat up and waited with her body slightly trembling as she tried to make a move against him. He knew, because upon casting the magic, a link formed between them.
This link mainly just told him if his slave held hostility against him while the others were basically the general location and if they were alive or dead. So after untying most of Bellatrix's bindings, Felix looked her over and felt sadness filling him again.
"What did you do to me, you brat!"
These were the first words Bellatrix said upon ungagging her. Felix just shifted his eyes as he truly is a brat at this moment. Even so, he didn't plan to remove the magic but actually plans to cast another few pieces of magic on her.
The first magic is the immortality spell from Furoufushi Shoujo No Naedoko Ryokouki. This is mainly to keep Bellatrix young for she is about fourteen years older than him. While the magicals tend to live longer compared to the non-magicals, they still age in appearance similar to each other.
So, even if it is mainly to keep her young looks he plans to put this magic on her. While the other magic is the Alchemic Golden Body that acts similar to the Super Soldier Serum. This alchemic body would put the body into a perfect state at the peak of human limits. It will also slightly adjust one to reach the golden ratio of their body. That is to say, Bellatrix's body will be curvy where it should and slender in others.
"Where are my clothes, you pervert brat!" Bellatrix asked with anger in her voice.
"Nearby. I had to make sure you didn't have some weapon or escape tool on you." Felix replied.
Bellatrix's eyes seem to flicker over to her neatly folded clothes with her undergarments on top. Felix also glanced over to see the pile, but didn't see the issue here. So he went back to looking at Bellatrix instead of a pile of clothes.
"Aren't you being a bit too cautious?" Bellatrix asked.
Felix pretended not to hear that as he shifted his focus to a different topic. He didn't find talking about his previous cautious behavior interesting.
"So how many of you came out to assassinate me this time?" Felix asked.
"It's just me." Bellatrix blurted out seemingly against her will. "The others and spies just gave me the information and polyjuice potion to sneak in."
"Oh." Felix guessed a bit.
It had been a few hours and since no one came looking nor jumped out to rescue her. Either they abandon her or the spies in Hogwarts didn't know or want to risk a rescue. It would be foolish to assume that there were no spies in the castle under Voldemort's control.
Thinking of spies, Felix found it interesting and a useful idea for Bellatrix. While he didn't really know of a good plan, he would just plant her in Voldemort's ranks as his own spy. He didn't actually have much use for her to hang around the castle nor did he want to lock her away in a box for the coming years.
For what would happen after Voldemort fell, Felix decided to deal with that when the time came. It should still be a few years until then since he wasn't ready nor did he have the ability to convince others to follow a plan. He is after all only twelve in the view of others.
"So, what do you think of becoming my spy?" Felix asked.
