These supplements are lovely to read. I feel like the original preoccupations of the game come through with some new twists and additions that feel very natural. The additional questions at the end of each archetype are fantastic and open up so many interesting possibilities for play (Is your novice from a place you have schemed your way through before? Were you more skilled than your expert before you lost your powers?). The visual design also looks so polished, I'm taking Canva notes (the cover for The Foresaken is particularly awesome).
I love how you took the Charlatan in a darker, less slapstick direction than I took the Impostor, more focused on actually avoiding detection than near-inevitably being caught. I also love that both of us put in an unimpressed familiar of the previous witch. The 'problem you're facing' prompt of a magical artefact wreaking havoc almost writes the scene by itself, while keeping storytelling options wonderfully open. The idea of the Expert Charlatan as a magical shopkeeper is just perfect.
I hope me leaving a comment isn't too awkward, I think it's awesome that we saw some of the same possibilities. I would love to play the Avatar sometime. Thanks for sharing your work!
