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. There are around 70 cards in total. Some of the cards we have seen before and some we haven't, but be ware, there are spoilers!
Today is Tiberius, who is dear to my heart despite being a studious, lonely, prickly young man who really only gets along with his twin, Livvy. He and Julian have a fraught, complex relationship that’s been a lot of fun to develop. Ty takes the Hermit card, here the Genius, because while brilliant, he is solitary and somewhat divorced from the ordinary world.
You’ll see some of Ty in City of Heavenly Fire.
I spy the Codex in his pile of books there. :)
