Never Alone

You've had a voice in your head for as long as you can remember. It's a nameless, formless thing that lives inside you. It was fine for a long time, but lately... you've made mistakes. You pissed it off. How do you survive when your closest acquaintance is your worst enemy, and it lives inside your mind? This one is more vague than my previous adventure; where it's set and when are up to you, if you want to define them. The goal here was the atmosphere and concept, not a highly specific setting. It's cyberpunk eldritch horror; you decide whether you're one of the monster's victims or a monster yourself. The AI can sometimes be fussy about possession and the player being subjected to mind control, so you might have to emphasise that. Rated Mature for body horror, violence, and general theme. Update: added AI instructions.
