Cassandra Jean has created Shadowhunter Tarot Cards. Some of the cards have been switched out for others (you can view all the ones that are out here), but Cassandra Clare announced on her tumblr that the card deck has been finalized. Each day, Cassie will try to post a new card on her tumblr. Some of the cards we have seen before and some we haven't, but be ware, there are spoilers!
Oh, this is fun! So Cassandra Jean has finished the complete Shadowhunter Tarot, so for the next … seventy-something days I’ll be posting a card a day in order, from the first card to the last. Some will be under spoiler cuts; some you’ll have seen before — I’ll explain why each character has the card they have.
This is Brother Zachariah as The Hierophant. The Hierophant is sometimes called the priest, the Shaman, or the Pope. “While the Magician was taking raw power from the Universe and manifesting it on the material plane, the Hierophant channels that power through society (as in the religions of the world).” The Silent Brothers are the studious monks of the Shadowhunter world, so it fit.
Above is the card Cassandra drew when she didn’t know who Brother Zachariah was/had been before he became a Brother. Below is the card she drew afterward! In both images, he holds the Mortal Sword.
