Mad King Thorn hasn't been seen in Tyria for over 250 years. Well, lore years, that is. He was actually seen this time about a year ago in the original Guild Wars
, which as you know has since given way to its much-heralded sequel.
Guild Wars 2's
first Halloween event is called Shadow of the Mad King, and ArenaNet
has announced that it will go live on October 22nd. Look for "new minigames, new dynamic events, and more," according to the blurb on the GW2
official site. There's even "an epic adventure in four acts" that runs through October 31st!
