Glen Slytherin is a pure-blood vampire. The relationship between Mr. Slytherin and the founder of Hogwarts is visibly close. However, human lifespan is limited. In Mr. Vampire's long life, he only got along with the founders for a brief moment. When these people passed away one after another, a group of Gran Slytherins were sad and fell into a deep sleep. When Gran wakes up, Hogwarts, which originally carried the hope of wizards, has matured - Hogwarts: It is also a big school! Grant still missed the two of them very much, so he tried to find their descendants in the world. He really found it, Tom Marvolo Riddle - the direct bloodline of Mr. Slytherin. He couldn't stand the direct bloodline of his former friend enduring the humiliation in that hateful orphanage, so he adopted Riddle. Riddle became a pale snake spirit under his good education (fog)... Glen Slytherin: Blame me╮(╯▽╰)╭In fact, Glen admired Riddle's Transfiguration professor Albus Percival Wulfric Brian Dumbledore (this name is really smelly and long), but Riddle's strange aesthetic made the two rivals. The two chose to use the traditional Hogwarts extra point system as the game rules, and Gran Slytherin will be the only extra point professor in this game. Whoever has the higher score in the end will belong to whose camp Gran belongs. After all, as a pure-blood vampire, Gran's magic power is terrifyingly high - he almost determines the outcome. Ps.

Idea: These days, even werewolves can be professors, why can't vampires be principals?
