WOW! This is a really creative idea and I feel like the flow of the rules makes a lot of sense! The lore, narrative voice, and characters are fun, thought-provoking, and flavorful. The doom aspect is fun and a great way of exploring storytelling.
My only thought is to recommend that players use a second tarot deck for easier shuffling since this add-on requires all the major and minor cards be shuffled together. That's if they want to use this at the same time as they play through Tangled Blessings. Great work!
