The Halloween 2010 event runs from Thursday, October 21, through Monday, November 1, 2010. It includes Trick-or-Treat Bags dropping foes, the return of Halloween collectors, the redecoration of Lion's Arch, Kamadan, Tomb of the Primeval Kings, and Droknar's Forge, and the return of Mad King Thorn who once again will terrorize the populace with 'hilarious' jokes while at the same time rewarding them with special holiday treats. He'll be making many appearances so be sure to get one of the special hats! This year, a set of brand-new Halloween quests will be introduced.
