Begin your training as a Shadowhunter by using Cassandra Clare's New York Institute Key! This collectible key will help you gain access to the library, the greenhouse, the training room, and more! This antique gold key has a beautiful stained glass topper reminiscent of the Institute's gothic cathedral, visible only to Shadowhunters. The key also comes with a beautiful lenticular card charm that displays all three Mortal Instruments and looks just like Madame Dorthea’s tarot card. It also comes with a demon and seraph blade charm so you can practice being a Shadowhunter again and again!
