I LOVE THIS!!!
Such an evocative background! I felt like I was watching a movie montage with voiceover narration.
The setting is completely atmospheric from page 1 through page 7 (I'm jealous that you didn't even need all 8 pages, you said, "Nah that's the whole thing." lol).
I do have a couple questions, as I may be running this in the near future. First, how do the players figure out that the only way to relinquish the curse is by using the noose? Should they know all of the info from the "Adventure Background and Overview"? If so, would it be best just send them all of that text? If I had the resources and time to do so, I would love to make a short film or animation of it with VO narration, just because that's how I originally imagined it.
As for the other question, if the witch won't return until the following Autumn Equinox, how are they to prove that they ended the curse to NPCs? Should I just let them lie about it and collect the non-XP rewards?
