"The Devil's Disciple."

The starting prompt was the title of a play by George Bernard Shaw.

I did some editing to this image, but only to fix it so that the heading of the contract says "My Soul" instead of "Your Soul" across its top, and also to flip things so that the heading is upside-down from our point of view, but right-side-up from the perspective of the young man who is about to sign the contract. I left everything else alone.
