It was kinda funny; I join up with a buddy to run AK, and I zone out of Ul'dah and into the dungeon, leaving Ul'dah in all it's Cascadier glory.
Forty minutes later, I zone out and suddenly it's Halloween. Halloween everywhere.
New music in the cities (which was quite festive, and easy on the ears) and a fun little quest line that ended on a "d'aww" moment. It's a neat distraction, and I hope as the event goes on there will be more to it. It lasts until the 1st of November, so everyone's got some time. Go and get your ghost costumes folks!
