I am currently working on a cosplay of Ellen from The Witch's House and I'm almost done with it. All I have to do is dye a white dress red. Because of this and a dream I had last night, I started writing a fanfic based on The Witch's House called The Witch's Asylum that is like a game where the character is refereed to as 'you' and 'you' are doing actions and experiencing emotions.
The jist of it is that after the ending to the Witch's House, 'Viola' goes insane and is haunted by 'Ellen' and is sent to an insane asylum where all the patients and workers mysteriously die in one night.
I will post no spoilers, but it basically flows like a game with having to pick up items and solve puzzles.
