The Halloween 2007 event ran from Thursday, October 25 until Wednesday, October 31, 2007. It included the return of Halloween collectors, the redecoration of Lion's Arch and Kamadan, and the return of Mad King Thorn who once again terrorized the populace with 'hilarious' jokes while at the same time rewarding them with special holiday treats. This event was similar to the past events of Halloween 2005 and Halloween 2006. This year a new item, the Trick-or-Treat Bag, and a new mini-game, the Costume Brawl, were added to the celebration.
