Chapter two: Nescio quid dicas.

The summer passed rather quickly for Salazar as he searched for the hidden room in the library (which he found the fifth day). He also noticed that he regained his abilities from the time when he was Slytherin. It was mostly Occlumency and Legilimency he had to train on, but also his Animagus form. He was a snake - which isn't really surprising. He had, however, a few more conversations with the Headmaster, telling him about the abilities and the room he found. It was behind a book-shelf, pretty near the entrance to the library. After having a long discussion with Dumbledore, they decided they will not tell McGonagall the truth, although Salazar knew that Dumbledore's warning would someday come true.

"Mark my words, Salazar. She is not dumb and will find it out. It is no point in hinding it from her, it would even be easer to both of you. Besides, it's not nice keeping secrets from your Head of House."

And Salazar agreed with him – at least about the first part – although he never said it out loud.

And McGonagall kept sending him those suspective glances.


He didn't care for how he looked like. At least not as Harry. But he did it as Salazar. All he noticed that changed in his look was that he got a tattoo burned on the left palm – the Slytherin crest. He was a bit amazed in how he survived a whole month without looking in the mirror. 'Cause when he did it casually someday, he received a shock. He didn't at all look like he did in Juny. His hair became blacker and longer and his eyes glew brighter green. He also seemed taller than he normally did. He just took the glasses off to see if he wasn't dreaming – he looked exactly like he did as Salazar. It was also then he noticed what he could see pretty well without glasses. Not as good as he did with them, but it was surprising anyway. He assumed that within weeks, he wouldn't need glasses.

Of course, he informed Dumbledore about it. The old man didn't seem suprised. When asked, he answered:

"Salazar, you know, I saw then change in your look and–"

"And of course it didn't occur to you to tell me?" Salazar exploded.

"Now, now. Don't scream. Unlike the pubic opinion, I am not deaf. And I thought you're smart enough to notice it yourself."

"Anything else you didn't tell me?" Salazar asked sarcastically.

"No, now I think it was all."

"How do you imagine to explain my new look to McGonagall? And everybody else?"

"Well, to the Wizarding World we can say that you grew your hair and darkened it. Minerwa, on the other hand– I assume you still don't want to tell her the truth?"

"No, no and once more: no!"

"OK, I just made sure. We can tell her the same: that you wanted to change your look and I threw a spell to do it."

"Deal."


McGonagall didn't seem convinced. She narrowed her eyes as she glanced from Albus to Salazar. She knew though that even if they were lying – which she was sure they were – she wasn't the one to discuss it with them. So she tried to let it go. But she couldn't. She listed up the facts she knew and that she noticed: he changed in look as well as in character; he was like this from coming up from the Chamber of Secrets. Something must have happened in there. Did Slytherin put som kind of spell that changed people who entered it? It would be the very truth: both Tom Riddle, Ginny Weasley and Harry Potter changed.

She then started researching in the library. She didn't find anything but some new spells she was sure he couldn't cast. They were too new for him. She then, after a long research, found some other spells, but nothing but one could change your character. That spell was an Ancient Greek reincarnation spell. But then again – that spell would be too old for him. He wouldn't possibly–? He couldn't have–?

And even if, who was Potter in his past life to change that much? It must have been pretty long ago, for in those times boys don't tend to have such long hair. And she have never met anyone with so black hair!

"Let's gather it all." she muttered to herself. "Coil-black and long hair, arisctocratic behavior, lived long ago and reincarnated by Slytherin's spell... Let's see..." she searched in her mind for a while, then suddenly stopped, shocked, as she realized the obvious. "Oh my godness, no!"


"I think she solved it." Salazar whispered to Albus at breakfast some days later. He kept glancing at McGonagall, who threw some not-so-subtle glances at the both males.

Dumbledore put down his cup filled with coffee.

"How do you know?" he asked.

"Mind reading." Salazar said casually, as if it was natural for 12 year-old boys to read their teachers minds. And, in fact, in Salazar's time, it was.

"What?" Albus almost screamed.

Salazar just shrugged.

They ate in silence for a while. Then, finally, McGonagall said:

"Potter?"

Salazar looked up from his breakfast.

"Yes, professor?" he asked.

"What exactly happened in the Chamber of Secrets?"

He smiled inwardly – he expected this question. He had the answer ready.

"I searched for Ginny and all of a sudden I found myself in front of an entrance. So I entered it and spoke to Tom Riddle. Then the basilisk came and I killed it. Oh, and I got help from Fawkes." he added, as an afterthought. After all, it wouldn't good to get on a phoenix's bad side – and forgetting him in such an action would be exactly that.

"Didn't you release any spell?"

"No, I don't think I did."

"But you've still got some explaining to do, haven't you, Salazar Slytherin?"

Salazar smiled slightly inwardly and answered:

"Nescio quid dicas."

"Of course you do! Don't lie to me. You're Salazar Slytherin and don't neglect that."

Salazar sighed. He didn't know McGonagall was that stubborn.

"Ipso facto, bene dicitis."

"And in English?" McGonagall asked.

Albus bent over and whispered something in her ear.

"Ah..." McGonagall said.

"How long have you known about it? I mean, about you being Slytherin?" she continued.

"A few days after the Chamber accident." Salazar replied.

"And you've lied to me! You said you grew and darkened your hair! How could you!" she burst out. "Minus 20 points to Gryffindor!" she then realized that school hasn't started yet.

Then, thinking about what she said, she realized one more thing.

"How ironic." she said, then laughed. "Salazar Slytherin in Gryffindor!"

She stopped laughing after a few seconds, thought she still giggled.

"Sorry. It's just so surreal."

They ate the rest of the breakfast in silence. Then, when Salazar was about to leave, Albus suddenly said:

"Salazar–"

"You call him Salazar?" McGonagall asked incredulous.

"Yes." Albus answered.

McGonagall turned to Salazar.

"And how am I supposed to call you?"

"Actually," Salazar said. "I prefer being called Salazar. And I'd be pleased if you call me as such."

"But, as I said," Albus interrupted. "Salazar, how large is your knowledge?"

"Quite a lot." Salazar admitted. "Except what I've already told you, I have reached quite high levels on every subject taught at Hogwarts, at least in Salazar's time. I also know wandless and Ancient magic, reading thoughts, basics of wandless flying..." he trailed off.

Albus and McGonagall stunned, shocked. Then McGonagall burst out:

"What? If you're so advanced in magic, then what should I teach you?"

"Probably the Transfiguration spells that've been found over the thousand years I've been gone?" Salazar suggested. "And I guess they are quite many."

"Thank you for the idea."

"OK, but I've really gotta go." Salazar said, opening the door.

"Where?" McGonagall asked curiously.

Salazar hesitated, but answered:

"To the Chamber of Secrets. I figured I must clean up there, seeing as I'll use it as my hideout for the next few years."

McGonagall looked like she considered something. Finally she said:

"Can I come with you?" she begged. "I mean, I wanna see the ancient place where the legendary Salazar Slytherin hid the mythical basilisk and where the famous Harry Potter killed it." she added.

"Sure." Salazar shrugged.

"Can I come?" Albus lit up, his eyes twinkled.

Salazar sighed.

"OK, come with us. But remember to take some brooms for yourself." he added.

"And you?"

"I can fly without broom."

"Oh."


The first thing Salazar stated when they were down there was that it was way too dirty. He waved his hand while thinking about a clean room. He then did the same thing the longer they came.

Then they did come to the mass of stones that fell over, separating Ron from Harry.

Salazar did some strange move with his hand and the stones exploded.

"What kind of charm was that?" Albus asked.

"The Exploding Charm." Salazar answered as he kept going. "I'm surprised you haven't heard of it."

"Neither have I." McGonagall admitted.

Suddenly, Salazar stopped. They have now arrived at the entrance to the Chamber.

[Open yourself.] he ordered in Parseltongue.

The snakes started to move, slowly making it possible to open the door. When Salazar did it, the smell that was inside hit him.

No wonder – a smell from a thousand years old basilisk, even if killed quite recently, isn't the best you can smell. In fact, it stinks.

He tried to breath through the mouth. When he mastered it, he walked up to the giant animal. Out of corner of his eye he saw that the both adults started investigating the Chamber.

He opened the basilisk's gape carefully and used the Cutting Charm to erase the teeth. He then hid it in a bag he took with him.

He took some shucks as well, then turned around to see the two adults in the middle of a research.

Sighing, he waved his hand to take away the carcass. Then he asked:

"Are you two ready yet?"


They apparently weren't ready. But after assuring they could come up themselves, Salazar headed towards the dungeons. Lately, he slept there more than at the Gryff's Tower.

He thought about his past life. About him, Salazar. About his friends, Godric, Rowena and Helga.

He thought about how they met. They went to the same school, Teuchiell's School For Young Wizards and Witches. They were in fact in the same class. They built a classmate-classmate relation to each other – nothing more, although he assumed that Rowena and Helga had been good friends once they all graduated. Then they separated. Helga had to come back to marry some wizard that his father chose – it was a tradition in the Hufflepuff family to let the father choose. Rowena signed up on some university in France. Godric immediately started searching for a job and Salazar... well, he traveled around the world. As both his parents died (they fell into the water in January and died out of cold) when he was a little kid, he lived since then at their cousin's place. With his wealth, he could afford the trip. On the journey he learned a lot geography magical history, and other types of magic than he knew before

Then, one day, when he was in Germany, he met his old classmate Godric Gryffindor in a pub. He tried to convince him to build a school with him, Rowena Ravenclaw and Helga Hufflepuff. At the beginning, he didn't agree, but as the time passed... And there he was.

And Salazar also thought about his brother.

Yes, Salazar Slytherin had had a younger brother, Silvan Slytherin. He was only one year younger than Salazar, but that was enough for Salazar and the other founders to treat him like a kid. Of course Silvan didn't like it. However, he found a playing mate – Richard Ravenclaw, Rowena's younger brother. They were exactly the same age, as Richard also was only one year younger than Rowena. Soon, they got the company in form of Gabrielle Gryffindor, Godric two years younger sister. They made a pack with only one goal – to annoy their siblings (and Helga) as much as they could.

It wasn't easy, as Silvan Slytherin was a Prince of the Great Britain. At least the Wizarding part of it. He couldn't afford to compromise himself in public, so they only pranked the four in private. Of course the founders didn't just let it pass – no, they pranked back.

And as Salazar also was a Prince (the Crown Prince to be exact, after his aunt Sapphire. Although Sapphire had had a daughter, Silvia, she couldn't be the Queen as she got disowned by Salazar's father, Salisbury, for drawing disgrace over the Slytherin family), the war was a very private thing. Only the two groups – and the house elves who were unlucky enough to clean up the mess they left after them – knew about the 'pranking war'.

He also thought about how historians got it wrong. There wasn't any fight over 'Slytherin's prejudices', as the history books usually call it. He didn't have any prejudices to the Muggleborns. He just thought that their parents, the Muggles, would hate and abuse them if they learned their child was a wizard – or a witch.

And, in fact, it happened sometimes. Or in 2/3 cases. And half of the abused Muggleborns even got burned. Burned.

Then Salazar was suddenly struck by a realization. What if the Muggles decided that burning their own witches wasn't enough and wanted to invade Hogwarts?

That's how Hogwarts got her anti-Muggle shields and Salazar Slytherin his reputation as a paranoiac.

But back as to why Salazar suddenly disappeared. Well, it was quite simple. Queen Sapphire II died and Salazar had to take over the reign. He became King Salazar the II. Therefore, he couldn't teach at Hogwarts anymore.

It was that simple. Salazar could not understand why the history books got it so wrong.
