Bitter Rivals, running from March 3rd to March 10th, gives players a chance to unlock the new Dwarf Slayer and Orc Choppa classes by completing quests and participating in the new Twisting Tower Realm vs. Realm Scenario. In Twisting Tower, the forces of Order and Destruction battle for control of a ruined Chaos tower while a vengeful god rains fire down upon both armies. The event kicks off the massive Call to Arms live update, which culminates in June with the opening of a brand-new raid dungeon zone, The Land of the Dead Mythic launches their four-month long Call to Arms live update for Warhammer Online this week, with the Bitter Rivals live event and the launch of their official forums.

Along with the launch of Bitter Rivals, Mythic has also opened the official forums for business, giving players an official place to bitch about balance issues, server lag, other players' moms - you know, the usual.
