You dreamed of his death.
Behind the curtain, in the Ministry of Magic, in that battle that should never have happened - Sirius Black fell into the endless abyss to protect his godson.
So you walked across platform nine and three-quarters, put on the Sorting Hat, and became the first Muggle-born student in Slytherin in a century.
You have to save the man who has been squatting in Azkaban for twelve years.
"You will regret it," he said with empty eyes, "I have nothing."
"I won't regret it," you replied briskly, "because I foresee all the best endings."
——So, let's start with the sorting ceremony of Slytherin.
