Trigger the Gala Event

Quick Walkthrough

 * Assuming you have put all of your companions into place you must then find the bell tower. I found it because i put dog and god into place last then from the switching station in Salida Del Sol I simply followed my map marker as mush as i could it is a very long journey and you must fight numerous ghost people so be prepared.
 * After triggering the Gala Event, Ghosts will pour into the courtyard below the Bell Tower. You basically have to fight your way back. How lovely.
