X_X (Pronounced "Double X") is a unique club made up of everyday folks, Anomalies, and Espers. It's home to the famous magician Houdinii with his huge following, the brilliant playwright Cassandra, and notorious figures like the phantom thief Chameleon and the gambler "21," both wanted by Midas Technologies. The club hosts regular meetups called "potlucks," and anyone who locates the spot and joins one can become a member. Many Anomaly Hunters look up to X_X. Beyond its legendary members, the resources stashed across the city by the group are a huge help for rookie Hunters looking to grow.
