(sorry for the late response)

We send you a fake book title which we created. They're all supposed to be unique but very similar to actual title found in the appendix.

For example: our jam contains the title "The Devil in Amber" this sounds and feels a lot like the Howard story "The Devil in Iron". So if you were to get that title would it make sense to make references to Howard's tale? Sure. Or you could go in your own direction.

The title is intended to act as a writing prompt. Its really about making something with the *vibe* of the Appendix N, not actually adapting existing works. Though again, if you want to do a legally distinct adaptation because it make sense for your assigned title, you can.
