Here's a quote regarding it:
Quote:
| It is currently known, according to the special Guild Wars edition of PC gamer, released in October, that the Ancient Dragons will be the primary antagonist of the PvE campaign. Other minor antagonists that are known at this time are the White Mantle and Palawa Joko and his army of the undead and fallen Sunspears. |
Who or what would you like to see be a villain or evil entity to corrupt and/or bring destruction to the heart of the three continents and the entire world?

Nothing more satisfying than slaying some huge monster.
