You get a button that gives you $10000 on each press, but also spawns a french woman from 15th century who blames you for being here
You can press the button maximum of 10000 times. Each time you press it you get $10000 dollars but an 18 year old woman from 15th century France gets spawned within one mile from you. It is a copy with all the memories of a real person from that period so don't worry about time travel paradoxes. She will spawn somewhere relatively safe so don't worry about accidental death at least not immediately.
She also knows that you are somehow responsible for her being here. She knows your face and could recognise you, and knows your current location (you had on button press) but not the name.
So you can get lots of money, but increased numbers of medieval french women are all accusing you of causing them to exist in this time.
