The Machine (Lethe and GUF)

You've seen it in your dreams. the darker area of The Machine. I don't understand it, not really, But I think I can control it for a little while. I'm supposed to only use it to assign the mortal souls and make them forget. But I think I can help you. I think I can make you forget, and assign your immortal self to a mortal frame, if you're willing to take the risk.
