500 years ago the tyrannical reign of the Krytan king Mad King Thorn came to end when he was deposed and slain by his oppressed subjects. Although his spirit was banished to the Underworld, legend says that he can return to the mortal realm for one day a year: on Halloween.
The Guild Wars 2 Shadow of the Mad King event will begin tonight at 02.00.
