Has anyone considered using plot twist (and plot twist: flashback) cards as benefits for harrowings?
My idea is that with every harrowing at the start of each chapter, I'll give each player 3 cards: 1 Flashback and 2 Plot Twist Cards for Past/Present/Future. Each plot twist card will tie into a harrowing card and this way the players have been foretold their destiny a little bit and have flexibility for their harrowing to come true.
Example: Describe Zellara drawing the Betrayal harrow card and describe how she predicts a sudden twist of alliances in your future (as well as still foreshadow any future chapter events). Then I'd hand him/her the "backstabbed" plot twist card).
I've never used the Plot Twist cards but that sounds cool!
