Soul Fuel

You are a cosmic entity traveling through space.

On your way home you were attacked by pirates, but managed to shake them off.

Problem is: you have run out of fuel.

Luckily there are a couple tiny creatures living in your toy pocket dimension.

If you corrupt their thoughts enough to have them commit sins, you can harvest their souls as fuel.

You don't have much time until the pirates get here,
try to to get at least 50 souls in the next 200 years!
