Almost one millennia ago, four great sorcerers built the first school of Witchcraft and Wizardry that the world had ever seen.
The four founders of the school were Helga Hufflepuff, Godric Gryffindor, Rowena Ravenclaw and Salazar Slytherin. Each of the founders had preferences on the students accepted at this school, Hogwarts. Gryffindor wanted only the brave to be able to enter, while Ravenclaw wished for only the most intelligent students to be schooled. Slytherin was of the opinion that only students of pureblood wizarding families should enter, whereas Hufflepuff preferred that was to be arranged so that all magic children could be educated there. After a long debate, Gryffindor came up with the idea of each founder having his or her own school House, and this they did.
However, soon an argument broke out between the four, and it seemed as though the school would crumble as soon as it had begun. After many months of feuding, Slytherin left the school, and all that the feuding abated after that.
The last part of this legend is true, however much of is was purely fiction. Slytherin did not cause this feud and he did not leave because of it. In fact, the reason Slytherin left was not because of the others, but because of his own father. I know; I was there.
Slytherin had no liking for the Dark Arts, although many would claim that he did. His father, Severus, and his elder brother, Sorvolo, however, both practised the Dark Arts. Severus Slytherin visited his son in Scotland, at Hogwarts, and tried to convince him to join them and practice the Dark Arts. Salazar tried to convince Godric, Rowena and Helga to let him leave, but Godric wouldn't. Slytherin didn't listen to his friends; he left after the Chamber was completed. He had no idea that Sorvolo had decided to place a Basilisk within the chamber in order to purge the school of muggleborns. Salazar and Sorvolo were both Parselmouths, they could both control snakes, and it was Sorvolo who had the intense hatred of muggleborns- whom the he called mudbloods-, whereas Salazar simply mistrusted them (he believed that it was necessary to not trust those who could have given our world away).
But I digress; Slytherin left Hogwarts and travelled to the North. It was there that he met up with two old friends, Hades Hemlock and Lexis Lunaria, both of which had helped build Hogwarts, but left soon after Godric announced that the school would welcome both pureblood and mudblood students. Hemlock had an old acquaintance, Pandora Pyrites, who later convinced them to build another magic school. That school was Durmstrang.
Slytherin died just before Durmstrang was complete. He watched as Pyrites left Lunaria and Hemlock and built a third school, Beauxbatons. He watched at Godric died after almost twenty years as headmaster of Hogwarts, and how Helga died soon after- of a broken heart I suppose. He watched as Rowena took charge of the school and as she established the Ministry of Magic.
Slytherin knew that before he had departed, he had left his unborn son with Rowena. He had left them solely to save himself from the Dark Arts. Yes, Slytherin had saved himself, but no others…
He watched as animosity grew evermore between the four houses after Rowena's death, until at last his own house was shunned from the rest of the school; and the outside world as well.
He looked on as his true heir, one Tom Marvolo Riddle, opened the Chamber and unleashed his brother's monstrous Basilisk.
He watched as young Riddle, then known as 'Voldemort' descended deep into the darkness that he himself had run from. Voldemort believed to be carrying out Salazar's wishes, when he was, in fact, carrying out Sorvolo's.
And he watched as Voldemort gathered others of his damned house and dragged them too unto the darkness.
Now, Slytherin means darkness; they are the darkness; Slytherin's damned children are everything he did not wish to be.
Yes, for to be a Slytherin in days of old and to be a Slytherin in this new age… well, they are entirely different things.
And I would know… because I am Slytherin.
