You live in a modest house, fairly big and quiet old fashioned. Recently your oldest brother has grown ill and you couldn't understand why. But soon after he started to speak in languages that didn't even make sense, clawing at walls, and showing up in random rooms you immediately called in a priest to get whatever was in him, out.

you hear a knock at your front door "Pardon? I am Doctor Abner Davids. I'm here to see your brother."
