You can approach this story helper in three ways: 1) go off the card’s meaning using the keywords and descriptions I provided, 2) ignore those descriptions, using the images alone to inspire you, or 3) use a combination of both the images and the descriptions to influence your story. Or, you can approach it in whichever method your muse gets excited about. That really is the point here, after all: to have fun with your writing and to just let it come without putting too much stress into it.
I decided to give very basic information for the cards so your muse can have more free reign with where it takes you, however if you want to know more about tarot and how to read the cards, two great books to start with are The Ultimate Tarot Guide & Seventy-Eight Degrees of Wisdom. There is also the really interesting book Tarot for Writers that talks about all sorts of different methods for using tarot cards in your writing process.
Remember: Even if what you come up with doesn’t make sense, keep it and come back to it later. If your muse is like mine then it most likely enjoys giving you puzzle pieces that need to be fit together over time rather than the whole story all at once. You never know what will connect your pieces together, so don’t trash something just because it doesn’t seem to go anywhere right away.
