Something happened. Something bad.
When you woke up, you had a new arm. Metallic, strong, better than your original one, really. All but for one thing: the micro-AI that controls it isn’t in sync with you. Sometimes it does what it wants, or does things to a greater or lesser degree than you’d like. Sometimes it’s like it takes control of your whole body. Like it has its own agenda.
