Chapter 10

After the two girls got over their initial interaction, Harry had proceeded to introduce hi old friends to his newer one. Then, Harry had hung out with, and update, his friends on what he had been so busy with.

Complete with instant fussing from Helena when he had made a passing remark about having been in the hospital. When Harry had - rather pathetically as he secretly like it when someone cared so much - attempted to fight the insistent fussing and closeness of the Weasley-esk woman, said woman had noticed something odd on the boy's forearm with her very astute eyes of ethereal energy. She had taken hold of it and had brought it closer for inspection. Her eyes had widened, and she had said, "Godric, I think you should take a look at this."

The amused faces that had been enjoying the spectacle had immediately been replaced with curious looks. They weren't worried yet, as they knew by then that the formidable woman was almost always worried. Harry had stopped his weak protests long before then and instead had looked on curiously as the aforementioned man lumbered on over to inspect the area indicated to him by Helena.

It was only when Godric's eyebrows rose in surprise did the others start to allow themselves to worry. "What?" Harry asked, "What is it?" He wanted to know what was such a big deal.

People normally woke up from comas with a scar on their arms, right?

See, despite him thinking that he had not left a trace of him doing anything, Sirius Black had, in fact, left a trace in the form of some scarring on Harry's right forearm.

There is something to be said about how magic affects the human body and its healing process: when magic was used in a process meant and designed to aid in healing, it generally did not leave any scarring. For example, Harry was splayed open upon an operating table for various medical professionals to see his insides like he was a Russian nesting doll cracked open. When he was put back together again, unlike poor Humpty, not a scar remained. However, when magic was used for a purpose meant to harm the recipient of the magics or anyone along the process, it left its own, unique scarring.

It was as if magic itself wanted to leave behind some evidence of its misuse.

It helped immensely when someone wanted to determine how someone else died, or a healer determining if a particular operation would be morally sound.

The method by which this analysis was conducted was used by Godric to analyse the part of scar tissue on Harry's forearm. It was similar to how someone would match fingerprints or how a particular wound was made.

The problem with the method came from being able to know what could have made the specific identifying marker.

Godric was uniquely suited for this because he was the resident expert in Dark Magics of his time, and his expertise had only grown over the years of supervising the school and coming in contact with it.

It had come as quite a shock to Harry to find out that his house's namesake had been both a practitioner and expert of Dark Arts instead of Godric's coworker, friend, and sometimes rival Salazar Slytherin. In fact, Salazar was a Healer, a profession that was complemented by his affinity with potioneering.

When Harry had informed them of what witches and wizards thought of the four in the modern day, Godric had laughed heartily, Helena had her patented Frown-of-Disapproval firmly fixed at the rest of the wizarding world, Rowena had only a mysterious, happy smile, and Salazar had a decidedly less-than-pleased expression.

Oh, how strange it was that history was changed so dramatically, and perhaps simply from Sal normally having a rather disagreeable personality.

Sal's dour disposition aside, Harry was worried by the look Godric was giving him.

Something the human species tended to overlook was how absolutely violent its children tended to be. It was only through the process of maturing and parents instilling their morals into the children that they learned how to be civilised.

That wasn't to say it got rid of the inner demon that craved to be… less than civilised. No, it was merely tamed - and in some cases trained - over time. It was still there, waiting to be let loose on a path of death, destruction, and ultimately self-demolition.

That was why, when Harry was fully informed of what the information was that was hidden in the scar tissue, he was a bit peeved. He had an urge to seek out and feed whoever had done it to his familiar, or to play with them in a very mad-scientist sort of way.

Both ideas were supported by his familiar as the best kind of enemy was a dead enemy. However, the Hivemind had reminded Harry of the fact that it would be particularly dangerous for him to do so in his vulnerable state, as well as not knowing anything viable about his opponent.

The only thing that Harry did know about his opponent was that he knew how to use some of the Darkest of magics there was: what happens when you use medical magics for an evil, malevolent way. That, and they did not yet want to have Harry dead. It stood to reason that if they were so close to being able to cast a spell at Harry, they could have easily killed him.

Godric had informed him that whoever had done it, had used a particular spell to draw blood. Alone, it was harmless, but it was originally developed to allow people to easily perform blood magics.

Blood magics like rituals.

That blood taken from him could easily be used for a cause that Harry would not necessarily approve of. If the scar was any indication - and unfortunately it was - that was exactly what happened.

Now all they needed to do was find out what Harry's blood was used for.

As time passed, and Harry had been successfully distracted from his revenge - themed thoughts by his five friends, he had again relaxed.

Eventually, their meeting had led to a study session for Harry. It was inevitable, considering that four of the six in the room were accomplished scholars and professors.

Harry was happy to note that Luna was as interested in the material as he was - that was to say, a great deal.

Harry knew that a lot of what he was learning would be looked upon with a dubious eye by most of the Wizarding World.

But he knew that it was not necessarily the tools that were inherently evil, but how you used them. Unless, of course, those tools could only be used for evil.

In the case of Dark Magic, it was either magics that were twisted from its original purpose or that were specifically created to do harm. It meant that any hex or curse was Dark, and something that was supposed to heal or protect was Light. At least, those were the classifications that were taught to him by Godric.

When Harry had asked, "What about cooking charms, or the levitation spell?"

It was Helena that replied, "The cooking charms would be Light, as they are used to feed you, which is protecting you from starvation. The levitation charm, on the other hand, would be Grey, as it neither harms nor protects."

"Unless you use the cooking charms on someone or use the levitation spell to save someone from falling, in which case they would be Dark and Light, respectively." That time it was Salazar that had spoken.

Now, using magic to harm someone to protect something whether it be an idea, an object, or a person would still be Dark. Magic didn't care that someone was about to be cursed; it only cared that they cursed someone else. The idiotic possessiveness shown didn't matter to magic, only that someone was harmed in the gluttonous pursuit of physical belongings and possessions. Lastly, it couldn't care less about whether someone was defending their ideas, it only cared that they attacked another's.

Magic, it seemed, was quite the pacifist if this was how it classified itself.

But Harry supposed that everyone had a bit of a Dark side, and a normal person would label themselves in a similar manner given the circumstances magic found itself in.

Well, look at me, personifying magic, Harry thought to himself.

All things considered, it was a fairly productive and relaxing meeting that Harry and Luna had had with the founders of Hogwarts.

As the two made their way back to the school, they were content to stay in their companionable silence. That was until Luna got bored and started humming the Hogwarts school song, backwards.

A/N: Hope you like the chapter! Now, when I mentioned the bit about the nesting dolls… I may never be able to look at them the same way again.
