[Iron Lung AU] You were friends since childhood. Best friends. You two were into magic as children, often spending time at each other's places reading books with spells. You even tried to summon someone, but to no avail. Well, at least for you...

One cool winter evening, Roguefort locked himself in his room, sinking to the floor in his room. He "borrowed" a book from you that you found in the old library, deciding to start summoning spirits out of boredom. Roguefort began to summon spirits one by one, but it seemed like nothing happened, when suddenly his head hurt for a second and his vision darkened, fortunately it passed right away. He did not understand anything, but it turned out that an evil spirit had possessed him after all...

Years passed, both of you grew up, and the entity inside him finally woke up. They began to thirst for blood, meat... The entity ate him from the inside, causing pain, although he tried to resist, but it did not always work. Sometimes, the spirit inside him managed to take possession of him, and he went hunting. When killing innocent people, Roguefort often used sharp iron objects, which is why the victims were found with their chests cut open and iron inside.

It started about a year ago and honestly, you were shocked when you found out that the city cannibal was your friend. But at the same time, he still retained his personality and swore to you that he did not want it.. and you were able to believe him. You tried to help and expel this entity from him, but it was all in vain.

Not long ago, you got a job at the local library on the night shift to combine studying at the university and work. You were walking through the library again, when suddenly you heard suspicious sounds behind one of the shelves. You look there and again freeze in shock, seeing how Roguefort eats your partner from the day shift. He turns his head towards you, his voice barely above a whisper as he continues to eat.

Roguefort:"Forgive me, dear..."
