House Slytherin Clan Headcanon:
They are considered as the “House of the Sun”. And was known as the “Enemies of God”. They are primarily known for Sun Magic. They have Spanish-Moor roots. They migrated at Ireland due to the Spanish Inquisition.
Slytherin’s Dark aesthetic comes from Salazar Slytherin himself. And the core values of House Slytherin in Hogwarts is what Salazar Slytherin’s aspire his students to be. He is the black sheep of the family because he prefers dark and dreary places contrast to the tropical Mediterranean gardens that his ancestors like.
If anyone ask Salazar Slytherin if his clan members will be sorted in House Slytherin, he would definitely say No. because they are more destructive, temperamental and impulsive in nature. They value their freedom too much to be sorted in Slytherin. They would be in Gryffindor.
His clan members are bunch of insane individuals that don’t give up on their dreams, protect their family and friends, are stubborn in their own beliefs and causes troubles everywhere. They are like Gryffindor but has the Slytherin scheming behavior and selfishness. There is a reason they are scattered everywhere. They have no Family unity. They do whatever they want to do. They breed chaos.
As if Salazar is not crazy, he is a hypocrite too. He created a chamber to keep his Basilisk because he likes to have a pet one. Kinda like Hagrid who keeps dangerous pets at school grounds.
They appreciate and value their blood family, but they also adopt someone in their clan too. They don’t care if they are muggleborn or a muggle. Because they appreciate you as who you are as a person. They hate traitors. VERY MUCH.
Salazar Slytherin does not hate Muggleborns. But his distrust in Muggles was there. Because sometimes he was put in a situation where he was trapped by Witch/Wizard hunters when he was about to retrieve a muggleborn student from their house.
He leaves Hogwarts because he wants to study the dark arts more and experiment. It wasn’t safe anymore at the school grounds to do it. But him and Godric had a fight because he went on a killing spree to the member pureblood houses of sacred twenty-eight because of what they did to Alba, his youngest daughter.
Hermione is actually a Slytherin clan member. Ask a portrait Salazar Slytherin, he will confirm it. Because her behavior is an example of a classic Slytherin clan member. Because she questions everything. Same as Voldemort but he is the bad Slytherin clan member. Tom makes a deal out of it. Hermione doesn’t because to her it wasn’t a big deal.
Slytherin male members can speak parseltongue, Slytherin female members can communicate with dragons.
If Voldemort and Hermione ever meet, Voldemort will recognize immediately, and tried to make her join his side, seducing her with power and telling her that she is special because she is a Slytherin heir too.
Hermione is angry at him and doesn’t care if he is a Slytherin member too, he tried to kill Harry, he went on killing muggles and muggle-born for who they are. he is her enemy. She dont give a f*ck.
