Version One:
On the other side of the mountain, beyond the sea, there were four young people. One day, they decided to start a school.
They used their surnames to recruit and train the students they favored.
Courage, ambition, loyalty, wisdom.
Version Two:
While Hogwarts was being renovated, the Four Founders once argued about where to put the four House common rooms.
Hufflepuff suggested, "We don't have many students right now. Why don't we all live together?"
Ravenclaw pointed out, "Do you want them to start fighting?"
Gryffindor immediately said, "I want a tower! Somewhere I can see the sun every day!"
Slytherin: "I've already picked the dungeons beneath the castle. They have a passage all the way down to the bottom of the Black Lake."
In the end, Slytherin added, "Oh, Helga, why don't you come live underground too? It's close to the kitchens."
Hufflepuff: "Huh? Is that so...?"
Ravenclaw just smiled without saying a word. Gryffindor: "???"
Pairing: Snake and Badger. A side story about the Four Founders.
Original setting details are being drafted.
