Starting from the 18th of October heroes and villains of paragon are encouraged to participate at a special Halloween themed event . "However, a dark shadow has fallen over this year's festivities. Word has spread from the shadowed town of Croatoa that strange things are headed south to spoil the holiday with their own evil celebrations. With the location of the Malleus Mundi still a mystery following it's disappearance last year, it's feared that new creatures might appear on the city streets. There have already been rumors that the Unseelie court may be sending fiends to paragon City to join the Vampires and werewolves that stalk the night on All Hallows Eve."
